" WASTEWATER FACILITIES PLANNING`} In completing wastewater facilities plans, municipalities must conduct popu- lation and service area projections, an infiltration/inflow analysis, a public involvement program, and an environ- mental impact assessment. Collection and treatment system alternatives are developed and evaluated prior to selecting a cost-effective plan for implementation. Pipe joint failure admitting infiltration into a sewer. Conditions like this and inflow conditions, roof drain connections, for example, are examined during the infiltration/inflow analysis. 7 '2 3 R E V Wastewater facilities planning is the first step in the Federal construc- tion grant process leading to construction of improved wastewater facilities. Completion of required analyses is mandatory to preserve grant eligibility for subsequent design and construction activities. Knowledge of the grant requirements, experience in dealing with regulatory agency personnel, and familiarity with the range of options available to provide improved facility operations make CH2M HILL well -qualified to perform facilities planning for our clients. We can also assist clients in grant administration and in gaining the best possible priority rating for their proposed projects. As a leader in wastewater treatment technology, CH2M HILL applied innovative and alternative approaches to solving wastewater problems before grant incentives were provided for such solutions. Now that greater emphasis is being placed on such solutions, CH2M HILL has an edge in conducting wastewater facilities planning projects incorpo- rating analyses of innovative and alternative processes._ We are familiar with other wastewater facilities planning services as well, including population and service area projections, infiltration/inflow analyses, public involvement programs, environmental impact assessments, flow and waste reduction techniques, and energy recovery or reduction measures. These analyses supplement the basic purpose of the facilities plan itself --to develop and evaluate transmission and treatment system alternatives. CHUM HILL can assemble a comprehensive team of engineers, environ- mental planners, scientists, and economists to work with clients as needed on all components of a facilities plan. Our capabilities include a, modern in-house computer system, which can help categorize manage- ment alternatives or predict the effects of future population growth and development patterns. Informational meetings are an important part of public participation in the planning process. Opinion surveys, •media presentations; newsletters, workshops, citizen participation, and communication programs also help gather public input. • 1 CH2M HILL has prepared wastewater facilities plans for large and small clients in many areas of the country. Our overall wastewater management experience includes the planning and design of some of the most advanced treatment systems in the world, and some of the simplest. This background gives CH2M HILL a range of unique insights and flexible approaches to wastewater planning. Our services include preparation of applications, total plans, and portions of plans for other consultants. Plans are developed in three phases. In the inventory phase, data are gathered to determine system characteristics. In the analysis phase, the various problems of the existing system are determined. Finally, in the projection and evaluation phase, alternative plans for serving existing and future sewered areas are evaluated and the details of a recommended plan are developed.

CLIENT: Milwaukee Metropolitan Sewerage District Milwaukee, Wisconsin The Milwaukee Metropolitan Sewerage District (MMSD) serves 26 communities within a 420 -square -mile area bordering Lake Michigan. In 1977, two courts determined that discharges from MMSD's sewer system were polluting Lake Michigan and that overflow from combined sewers was a major contributor to pollution in the Milwaukee River. To comply with newly enacted state and federal laws that set standards for effluent discharges and to meet stringent requirements established for Milwaukee under the court orders for the substantial elimination of combined sewer overflow problems, MMSD undertook a 12 -year, $1.6 billion water pollution abatement program. This long-term, complex program, begun in 1976, is a major facility planning, design, and construction effort involving a staff of over 500 from more than 15 consulting firms. The project itself consists of rehabilitation of the Jones Island Wastewater Treatment Plant, expansion of the South Shore Wastewater Treatment Plant, rehabilitation of the sewage collection system, substantial elimination of combined sewer overflows, establishment of &Total Solids Management Program, and construction of a series of interceptors to eliminate smaller wastewater treatment plants. Recognizing the complexity of these tasks and the need for innovative management, MMSD has operated under,a Program Management concept from the beginning of the project.- This approach has vested sole -source responsibility for the management and technical performance of the program in a single firm--CH2M HILL. As head of the consulting consortium formed for the Milwaukee. project, CH2M HILL is accountable directly to MMSD for all program tasks, regardless of which firm or individual is actually performing the work. In addition to overall program/project management --which includes project control (cost/schedule), strategic planning, and assistance in funding de'velopment--CH2M HILL is responsible for facility planning, environmental assessment, preliminary engineering, design, and construction management, including bid preparation and analysis. IC By following a Program Management approach, MMSD has 5 relieved itself of many of the burdens of project super- ° vision. In addition, centralization of responsibility has o saved both time and money --a high level of efficiency has been realized in the planning and organization of the work and the effects of inflation will be more easily controlled over the life of the project. An indication of how successful this approach has been comes from the Regional Office of EPA, which has com- plimented the program by noting that facility planning has been accomplished in 2-1/2 years instead of the more than 5 years it would have taken under traditional approaches. A number of management techniques and organizational arrangements have been employed to support the efficiency and economy goals of the program, including: ■ Accelerated facilities planning with concurrent environmental studies, infiltration/inflow analysis, and SSES--together with tight construction management --will save 2-1/2 years of design time and over 3 years of construction time, saving a potential $300 million in construction costs. ■ Close coordination with regulatory agencies, careful matching of funding with program elements, and "fast -track" reviews and approvals were implemented to save additional time and expense. ■ Technical expertise is provided as needed, freeing the project from the long-term cost of permanent personnel. ■ Central management fixes responsibility for quality control and enables systems and services to be standardized for all tasks of the program. ■ A community involvement program is maintained to permit citizens to participate in the evaluation and selection of project alternatives. • Involvement of minority business enterprise is coordinated and aggressively pursued to meet or exceed established community or regulatory goals. ■ Design packages are reviewed for constructability, optimizing scheduling, cash flow, resource availability, and owner -managed construction opportunities. ■ Work being performed on design packages that "cut across" facilities is internally monitored and managed to ensure coordination among designs. OUWATER RESOURCE PLANNING AND DEVELOPMENT CH2M HILL has 30 years of experience and broad capabilities in planning, designing, and supervising the construction of both large and small water resources development projects. Our clientsprojects have provided water supplies for irrigation, municipal and industrial uses, flood control, hydro- electric power development, water quality control, fish and wildlife enhance- ment, and conjunctive use of surface and ground water. All types of water resource projects, from the design of a dam and reservoir to the establishment of a water quality management control policy for a watershed, require a multi- discipline effort. CH2M HILL's project teams have all of the capabilities needed to work effectively with the client in water resources planning and development. Indian Valley Dam and Reservoir, designed by CH2M HILL for the -Polo County Flood Control and Water Conservation District in California, performs all of the above -described functions except power generation. In addition to the design, CH2M HILL's services included an evaluation of the existing irrigation system; water rights evaluations for acquisition through bond financing; financial analyses and engineering reports in support of bond and federal loan financing for the dam and reservoir; and assistance in long-range planning designed to ensure maximum use of available water resources.

For the Central Nebraska Public Power and Irrigation District, we prepared a master plan for enlargement and rehabilitation of its 67,000 acre E65 irrigation system. The plan included a system for conjunctive surface and ground water management. We also studied a proposed 40,000 kW hydroelectric power plant to be added to the irrigation outlet of Kingsley Dam on the North Platte River. For the Sacramento District Office of the U.S. Army Corps of Engineers, we prepared a design memorandum on hydrology and preliminary feasibility studies far the proposed Humboldt River project in Nevada. At Oroville Dam and Reservoir, for the State of California, and at New Don Pedro Reservoir, for the Modesto and Turlock Irrigation Districts, CH2M HILL planned, designed, and supervised the construction of comprehensive recre- ation facilities. In serving the Municipality of Metropolitan Seattle, we prepared a compre hensive water resources management plan for the Green and Cedar River Basins. Conjunctive surface and ground water supplies, streamflow mainte- nance for recreation and fishery enhancement, watershed storage for flood control, hydroelectric power, and water supply were among the considerations CH2M HILL and Trintoplan Consultants, Ltd (our joint venture partner). provided planning and design services to the Water and Sewage Authority, Trinidad. West Indies, on a major water supply project - The components of this multipurpose system include an earthen dam and raw water storage reservoir (35,000 acre - feet capacity), two raw water pump stations, more than 50 miles of large transmission pipelines, a 72-mgd treatment plant, and several distribution system pump stations and reservoirs. For the Placer County Water Agency's yliddle Fork American River project, we designed four hydroelectric powerhouses and associated substations with a total capacity of 210,000 kW.

I A ■ H ■■ WATER QUALITY AND, • CAKE EUTROPHICATION STUDIES CLIENT: Florida Sugar Cane League Clewiston, Florida In 1975, the Environmental Quality Committee of the Florida Sugar Cane League retained our firm to prepare a report on the water quality of Lake Okeechobee, the second largest lake in the United States. After a thorough analysis of published information on the lake, we recommended a program of further study, including a comprehensive evaluation of water quality in the Everglades Agricultural Area (EAA) south of the lake. The EAA com-• prises approximately 710,000 acres of peat and muck soils. The water quality study involved the determination of nitrogen, phosphorus, and water balances for typical sugarcane, pasture, and vegetable land use areas. The quantity and quality of backpumped and irrigation waters were continuously monitored and sampled at three representative farms. Five checkpoint sites were also monitored periodically, as were several private drainage districts that pump water directly into Lake Okeechobee. CH2M HILL also assessed the effects of agricultural practices such as fertilizer application rates, water table control, and type of crop. The results of the study, which was carried out jointly with the South Florida Water Management District, form a'basis for future water manage- ment decisions in the EAA.

We have more than 30 years' experience formulating financial plans. for municipalities and special purpose districts. These plans can. be simple, requiring only one or two sources of revenue, or complex, requiring revenue from multiple sources such as grants, bonds, taxes, assessments, user fees, and special or general funds. With our assistance, municipalities and special districts can more easily develop the ordinances, methods, and specific procedures to provide the proper balance of revenue for satisfying short- and long-term project expenditures. We have developed computer programs for financial plans that allow rapid analysis of such variables as interest rates, payment methods, phase development schedules, and revenue sources themselves. Arch Cape Service District, Clatsop County, Oregon, used such a program to monitor past expenditures and to estimate future cash flow involved with its sewerage system.

Our role has varied, consistent with the nature of the project, the techniques used, and extent of. our assistance. We have designed, executed, and evaluated the effectiveness of each major phase of public involvement: 1. Information dissemination --press releases and announce- -ments for radio, television, newspaper, and magazine coverage; leaflets and brochures; mailed notices; oral presentations at public meetings; video tapes, slide shows, and color movies. Information acquisition --interviews, telephone polls, mailed surveys, and questionnaires. 3. Information interchange --workshops, public meetings, public hearings, informal group sessions, and negotiations. Representative projects in which citizen participation was a major consideration are listed below: ALUMAX ALUMINUM REDUCTION ALUMAX PACIFIC CORPORATION UMATILLA, OREGON We prepared a community impact dinated the proposal with agencie views, and presented our finding PLANT study for public use, Coor- s, conducted agency inter- s at public hearings. BEND WASTEWATER FACILITIES PLAN CITY,OF BEND, OREGON During sewer' right-of-way acquisition, we personally con- tacted each property owner to explain the project and begin purchase negotiations. We also conducted the basic public involvement program required by EPA regulations. BROWNSVILLE CITY WATER SUPPLY BROWNSVILLE, OREGON Public information, public meetings, public hearings, and interviews were conducted for this HUD -financed water supply project. CHEHALIS, WASHINGTON APPLICATIONS FOR HUD BLOCK GRANTS As part of a successful effort in applying for HUD Community Development Block Grant funds for the City of Chehalis, we designed and directed the required citizen involvement pro- gram. This included printing leaflets, publicizing and con- ducting•citizen meetings, and organizing public hearings for both the Planning Commission and City Council. 1-7 PUBLIC INVOLVEMENT PROGRAMS CORVALLIS, CITY OF RIVERFRONT PARK MASTER PLAN CORVALLIS, OREGON Citizens were actually part of the planning and design team for the Corvallis Riverfront Park. We conducted three work- shops for goal setting, defining design alternatives, and preparing a refined master plan. Extensive public notifica- tion was accomplished by mail, news releases, and advertising. CH2M HILL also conducted work sessions with the project advisory committee and city staff. The public involvement process produced strong local interest and enough support to make the park a reality. Many workshops participants later became volunteers who helped with improvements on the riverfront. GAINESVILLE, CITY OF METROPOLITAN TRANSPORTATION PLANNING ORGANIZATION BICYCLE SYSTEM PLAN GAINESVILLE, FLORIDA Public involvement was a vital aspect in the development of a bicycle system plan because of widely divergent philosophies concerning bicycle use. Monthly workshops were held with the 25 -member Citizens Review Committee, whose membership included bicyclists, motorists, students, and representatives of the Florida Department of Transportation (DOT), the city and county staffs, and the Florida Utilities Council. Members of this coalition actively participated in the formulation of the final system plan. CH2M HILL planners also gave presen- tations before the City Commission, County Council, and the Florida DOT. HELEN S. HOWORTH COMMUNITY PARK PINELLAS PARK, FLORIDA Through a series of hands-on public workshops, the citizens of Pinellas Park designed their own 60 -acre community park with the help of CH2M HILL planners. Goals were established, needs were identified, and alternative park designs were formulated before the final design was approved by the City Commission. The public involvement program included work- shops, meetings, interviews, newspaper articles, and public sessions. IDAHO FALLS, CITY OF ELECTRIC TRANSMISSION LINE IDAHO FALLS, IDAHO CH2M HILL worked with local citizens to identify an acceptable transmission line corridor that would not only meet the long- term needs of the city but would be accepted by area resi- dents as well.

PUBLIC INVOLVEMENT PROGRAMS IDAHO TRANSPORTATION DEPARTMENT 1-90 LOCATION ANALYSIS ENVIRONMENTAL IMPACT STATEMENT DIVISION OF HIGHWAYS COEUR d'ALENE, IDAHO As part of a 2 -1/2 -year study to determine the route for 1-90 north of Lake Coeur d'Alene, special effort was made to incorporate the community's views. We developed a pro- gram in which all interested groups of citizens met with staff from the Idaho Division of Highways in a series of workshops to establish planning criteria for the projects. Through this exchange, the division developed additional alternatives for study and the citizens used the criteria to evaluate alternatives and list preferences. The results were communicated to the Idaho Board of Transportation and in- corporated into the EIS and the decision making process. A final hearing concerning the corridor location was then held after publication and review of the draft EIS. JBF SCIENTIFIC CORPORATION POTENTIAL SOLAR ELECTRIC USE STUDY WILMINGTON, MASSACHUSETTS The Solar Energy Research Institute of the U.S. Department of Energy conducted a series of studies to assess the poten- tial for solar electric technologies for six regions of the United States. For studies in the ten -state Northwest Region, JBF Scientific retained CH2M HILL to conduct a public aware- ness and participation program. First, we helped identify potential owners, users, and other persons concerned with the acceleration of the practical uses of solar electric generat- ing systems.' After more than 1,000 people were contacted, a select group was chosen to participate in a series of work- shops and seminars. CH2M HILL coordinated workshops and seminars in Omaha, Portland, Anchorage, and Honolulu; facilitated discussion sessions with program participants; recorded proceedings and published their results; and served as a local liaison for information dissemination. LOWELL NEIGHBORHOOD PLAN EVERETT, WASHINGTON CH2M HILL staff worked closely with local citizens and city staff in planning for future neighborhood land uses and public facilities.` Work included the preparation and distribution of citizen surveys and attendance at numerous small and large meetings during which goals, policies, and plans for the neighborhood were developed. Negotiations with owners of adjacent industrial property were also included in the public participation process. 3-7 PUBLIC INVOLVEMENT PROGRAMS MUNSEL LAKE MOBILE HOME PARK R. L. KUEBLER ENTERPRISES ESCONDIDO, CALIFORNIA Our planners interviewed local property owners and businesses to determine the need for a new mobile home park and to identify individuals and groups who would support the project.

Where overall water resource conservation is a goal, reclamation for beneficial reuse is another wastewater management objective. Advanced wastewater treatment (AWT) technology, with its ability to produce effluents of near -drinking -water quality, is a vital weapon in this battle to conserve and protect our water resources. In the first full-scale application of AWT concepts, CH2M HILL worked with the South Tahoe Public Utility District to combine biological and physical/chemical treatment processes in a 7.5-mgd plant. The tech- nology developed in this successful, pioneering effort has since been greatly improved by CH2M HILL and used throughout the. country. We have•continued to play a role of leadership in the development, refinement, and application of AWT technology. Our design and operation experience includes a variety of 'AWT processes: phosphorus removal by chemical precipitation, recarbonation, dual- and'mixed-media filtration, ammonia stripping, breakpoint chlorination, clinoptilolite ion exchange, biological nitrification-denitrification, reverse osmosis,, and activated carbon adsorption. Our ancillary process designs have 'included lime recalcination, carbon regeneration, sodium hypochlorite generation, various gas recovery systems, and the Ammonia Removal and Recovery Process. Through past service to our clients, we offer unparalleled knowledge and experience in the AWT field. With this "know-how," we can approach each situation uniquely and give careful consideration to factors such as influent characteristics, water -quality objectives, reuse requirements; financial capabilities., energy conservation, environmental effects, plant size and location, and existing treatment facilities. Y (over) The Tahoe -Truckee AWT Plant, California. CH2M HILL's capabilities on AWT projects span development and testing, feasibility studies, process comparisons, preliminary and final design, construction supervision, plant startup and operation, and operator training. A few of our clients' AWT projects are briefly outlined below. For the Tahoe -Truckee Sanitation Agency of Truckee, California, CH2M HILL designed a 4.8-mgd AWT plant. The treatment process includes high -purity -oxygen activated sludge, phosphorus removal by lime coagulation, recarbonation, dual -media filtration, activated carbon adsorption, and nitrogen removal by ion exchange. For the Upper Occoquan Sewage Authority, Fairfax County, Virginia, we designed a 15-mgd AWT plant with a treatment process similar to the Tahoe-Tuckee plant. After storage in a recreational reservoir, reclaimed water from this plant is released to Occoquan Reservoir as a usable portion of the area's raw -water supply. For the Unified Sewerage Agency, Washington County, Oregon, we designed a 15-mgd AWT plant that includes phosphorus removal by alum coagulation and mixed -media filtration. For the City of Gainesville, Florida, we designed a 7-mgd AWT plant that includes single stage activated sludge nitrification followed by denitrification in the final effluent filters. Phosphorus removal is by alum feed to the aeration basins. For the Denver Board of Water Commissioners, CH2M HILL is acting as technical consultant and designer on a program aimed at the develop- ment of full-scale water reclamation processes that will ultimately permit direct reuse of wastewater effluents. For the Milwaukee Metropolitan Sewerage District, Milwaukee, Wisconsin, CH2M HILL piloted AWT processes including chemical coagulation, sedimentation, filtration, and ozone disinfection. In major pilot plant studies for the City and County of San Francisco, California, and for the Toray Engineering Company of Osaka, Japan, we tested various physical/chemical and biological AWT processes. Lpper 1k c,}gLh n Sewage Authority's AWT plan', Virginia ■■ ■■ ADVANCED WASTE TREATMENT DESIGN EXPERIENCE In the early 1960's CH2M HILL, on the Lake Tahoe project, provided the major thrust toward today's advanced waste treatment technology by first combining biological and physical/chemical processes into a major advanced waste treatment design. The successful Tahoe project was the pioneer demonstration for economical use of lime as a coagulant; recovery and reclamation of lime for reuse; large-scale nitrogen stripping; mixed media filtration of secondary effluent; design of carbon columns for removal of taste, odor, color, ABS, and trace organics; and regenera- tion of carbon for reuse. UPPER OCCOQUAN SEWAGE AUTHORITY FAIRFAX COUNTY, VIRGINIA This 22.5-mgd plant includes activated sludge followed by phosphorus removal with lime coagulation, nitrogen removal utilizing clinoptilolite ion exchange, mixed media filtration, carbon adsorption, lime recalcination, ion exchange media and carbon regeneration, and sludge incineration. The plant will utilize the first closed -cycle ammonia stripping process for exchange media regeneration. The ammonia removal and recovery process (ARRP) was developed by CH2M HILL to eliminate the major objections to normal stripping (scaling, temperature limitations, and discharge of ammonia to the air) . The process includes recovery of ammonia nitrogen in the form of common fertilizers such as ammonia sulfate and aqua ammonia, which can be sold or used as byproducts. TAHOE-TRUCKEE SANITATION AGENCY TAHOE CITY, CALIFORNIA This 7.5-mgd treatment plant includes a pure -oxygen -activated sludge process; lime treatment with two -stage recarbonation; mixed media filtration; activated carbon adsorption; ion exchange for ammonia removal; and chlorination for disinfection. Additional processes include the aforementioned closed -cycle ammonia removal and recovery for the regenerate stream; activated carbon regeneration in multiple -hearth furnaces; and dewatering of the chemical precipitates with filter presses. As with all of our design and predesign considerations, CH2M HILL made a detailed cost-effectiveness analysis of all possible processes to achieve a certain effluent requirement. The Tahoe - Truckee project involved consideration of pure oxygen. versus conventional air activated sludge; use of ozone in place of recommended chlorine for disinfction and/or activated carbon adsorption; use of alternative nitrogen removal processes including ion exchange and vacuum degasifying of the ADVANCED WASTE TREATMENT DESIGN EXPERIENCE I regenerate solution; use of alum and ferric chloride as a , coagulant versus lime; use of anaerobic sludge digestion versus incineration; and use of virgin lime versus recalcina- tion. I The closed -cycle ammonia recovery process using acid absorption greatly simplifies the ammonia removal capabilities in cold climates such as exist in the Lake Tahoe area and Madison. This process, in combination with ion exchange, is one of the more cost-effective solutions to ammonia removal _ in cold climates. UNIFIED SEWERAGE AGENCY WASHINGTON COUNTY. OREGON This advanced waste treatment plant was designed for an initial capacity of 15 mgd, with peak flows of 45 mgd. Three alternative degrees of treatment were examined, including a detailed study of land application of secondary effluent. Two treatment systems and seven solids handling plans were examined in detail. The final plant will include pure -oxygen - activated sludge followed by alum coagulation, mixed media filtration, and disinfection using chlorine or ozone. Sludge from the primary, secondary, and tertiary treatment stages will be anaerobically digested and applied to land. WASHINGTON SUBURBAN SANITARY COMMISSION MONTGOMERY COUNTY, MARYLAND This initial 60-mgd capacity advanced waste treatment plant has a maximum dry weather capacity of approximately 90 mgd, with an ultimate capacity of 150 mgd. It involves all of the processes described for the Upper Occoquan Sewage Authority and, in addition, breakpoint chlorination for ammonia removal. Final design of this facility was preceded by a detailed site selection study, an in-depth pipeline and pump station route selection study for the interconnecting sewers and force mains, and a detailed predesign report fully describing all aspects of the proposed facility. CLARK COUNTY, NEVADA This 80-mgd advanced waste treatment plant will treat secondary effluent from the three major sewage treatment plants in the Las Vegas Basin with a process including lime coagulation for phosphorus removal followed by mixed media filtration and carbon adsorption. Lime recalcination and carbon regeneration are also planned. Prior to selection of this process 15 alternate treatment plants were considered, involving land application of secondary effluents; evaporation ponds, and combinations of treatment, land irrigation, and evaporation.

The City and County of Denver, although near abundant pure water in the form of snowpack, is situated in .a semi -arid region of Colorado that receives less than 15 inches per year average precipitation. Through the acquisition of water rights on Colorado's western slope and the implemen- tation of transmountain diversion systems, Denver has beneficially used western slope waters in conjunction with available eastern slope sources. As Denver's population has grown, so have the need and demand for water and water supply facilities. Denver Water Department projections indicate that this trend will continue, with .large amounts of additional supply needed by the 1990's. One possible alternative for augmenting fu- ture supply is successive use or reuse of water. In anticipation of this shortage, the Denver Board of Water Commission- ers embarked on a long-term program to evaluate the feasibility of direct reuse of water. Initial steps taken include the design and construction of a small test treatment facility, research at the University of Colorado through the establishment of a cooperative program with its civil and en- vironmental engineering departments, and application for and receipt of research funds from the U.S. Environmental Protection Agency. After a detailed investigation of qualified engineering consultants, CH2M HILL was retained to augment the project team to investigate the direct reuse of water. ii C 1` I N I I -■.1•I.■ RAMD MIX aOCCUTAIEON a Y�.W.Alll CHEMICAL SYSTEM d gNofl IO.IIN .w11 O[.110.1. paTMfl aALLAST POND [CARBON All ON t SELECTIVE ION U.

This 1-mgd plant will demon- strate the technical and economic feasibility, reliability, public acceptability, safety, and health effects associated with a reuse facility designed to pro- duce potable water equaling or exceeding the excellent quality of Denver's water. This demonstration plant will be operated and the effluent tested for up to 5 years prior to construction of the larger facility. The prototype plant will treat secondary effluent from the Metropolitan Denver Sewage Treatment Plant. The plant's process flow will include: • Rapid mixing, flocculaton, sedimentation, and recarbonation • Mixed media filtration • Selective ion exchange for ammonia removal, with regenerant ammonia removal and recovery • Activated carbon adsorption and carbon regeneration • Chemical oxidation with ozone • Reverse osmosis for demineralization • Disinfection Throughout the life of the prototype plant, numerous water samples will be drawn for intensive, sophisticated laboratory analysis. CH2M HILL completed final design in the fall of 1980, construction began early in 1981, and startup is expected early in 1983. The low bid for con- struction of the plant was approximately $16.2 million, with a total program cost expected to be approximately $29 million. Denver Potable Water Reuse Demonstration Plant. no KANAPAHA ADVANCED WASTEWATER 0o TREATMENT PLANT CLIENT: Gainesville Regional Utilities City of Gainesville, Florida The 1971 10 -Year Wastewater Plan for the City of Gainesville by CH2M HILL recommended construction of 7.0-mgd wastewater treatment plant to serve rapidly growing suburban areas west of the City. t - Because the City lies within a 300 -square -mile area that has no surface outflow, difficulties were encountered in locating the plant and determining means for disposing of treatment plant effluent. All urban and agricultural runoffs, as well as existing wastewater plant effluents in the area, are intro- duced to the ground -water aquifer via small streams which flow into solution cavities, or "sinkholes," that have formed in the shallow lime rock strata characteristic of this area. The Plan recommended locating the plant adjacent to Haile Sink and Lake Kanapaha. This natural connection to the aquifer could prove economically advantageous if incorporated into the plant's disposal plan. Kanapaha Advanced Wastewater Treatment Plant, Gainesville, Florida. Disposal and treatment alternatives were developed. After careful evaluation of environmental, economic, and logistical considerations with the Environmental Protection Agency, the Department of Environmental Regulation, and the City, effluent disposal to gravity -fed, ground -water recharge wells was selected as the best solution. Cost and geologic condi- tions made effluent disposal by means such as spray irrigation and deep -well disposal impractical. Discharge to the surface waters of Lake Kanapaha was selected as the alternate disposal plan. Recognizing that disposal to wells recharging a freshwater aquifer (and alter- natively to a surface water) requires a high quality effluent, CH2M HILL designed the Kanapaha Plant to include activated single -stage biological nitrification; followed by deep -bed, downflow filtration for denitrification (nitrogen removal), and by postaeration and chlorination. Alum can be added to the aeration basin feed for phosphorus removal, which is needed only when discharging to Lake Kanapaha. The plant has been in full operation since January 1978 and has consistently met all effluent requirements. The Kanapaha Plant is an impressive example of efficient and innovative technology applied in response to unique conditions. ®D WILLOW LAKE ®1 WASTEWATER TREATMENT PLANT 1 Y 4M1% Y CLIENT: City of Salem, Oregon M1 Th $18 5 'Ili n x nsi n ro'ect at Salem's Willow Lake million e . o e pa o p 1 Wastewater Treatment Plant has been in operation since December 1976. The new treatment system meets required effluent standards even though the influent flow increases abruptly during the two -month cahning.season. The popula- tion equivalent increases from 100,000 to 800,000 as a result of the foodprocessing waste discharges. A high -purity oxygen activated sludge system was selected as a result of CH2M HILL's major pilot plant study for the City. This system is the key process in effectively treating 35 mgd of high -strength mixed canning and municipal wastes. An existing trickling filter system operates in parallel with the activated sludge system. Peak wet -weather capacity for this plant is 105 mgd. Waste sludges are anaerobically digested and stored. During the dry -weather season, liquid digested sludge commercially called "BIOGRO" is transported by truck and spread on croplands. f._.. r. '.Y'. 3ryry } I r+. � .. � .

Advanced wastewater treatment at the plant will help protect Lake Tahoe and the Truckee River by producing an effluent of near -drinking -water quality. The $19.2 -million Tahoe -Truckee Water Reclamation Plant, now under construction along the scenic banks of -the Truckee River, is designed to blend pleasingly with its natural sur- roundings. The treatment process consists of high -purity -oxygen activated sludge secondary treatment followed by phosphorus removal by lime coagulation, recarbonation, dual -media filtration, activated carbon adsorption, and nitrogen removal by ion exhange. Anaerobically-digested organic and lime sludges will be dewatered and landfilled. Carbon will be recovered and reused through regeneration in a multiple -hearth furnace system. Carbon dioxide will be recovered from both the activated sludge system and the digester gas boiler system for use in the recarbonation process. Through use of the Ammonia Removal and Recovery Process (ARRP), valuable ammonium sulfate fertilizer will be a by- product of nitrogen removal at the plant. This process, the first closed -tyke ammonia -stripping process for ion exchange media regeneration, was developed by CH2M HILL. Another unique feature of the design is a combination piping, electrical conduit, pedestrian, and light -vehicle corridor that runs the full length of the plant. This corridor will provide the operating staff with convenient access and pro- tection during cold weather conditions. (Temperatures in this area have been as low as -45°F.) It will also allow easy access for maintenance and flexibility for future plant expansions. Although the wastewater will be highly purified, regional regulations prohibit its direct discharge to surface lakes or streams. Thus, the plant effluent will be discharged to an automated underground percolation system consisting of 80,000 lineal feet of perforated pipe. After discharge, the effluent will join the natural ground waters and eventually reach the Truckee River. The TTSA comprises five districts that serve the North Lake Tahoe and Truckee areas. Although only a small population lives in the area permanently, a dramatic increase occurs with the influx of seasonal residents and tourists. This initial stage of the plant is designed to serve a population equivalent of 54, 500 in the year 1985. It's peak capacity is 9 mgd. Plans call for doubling the plant's capacity by the year 2020. CH2M HILL has provided complete design and construction - supervision services on the regional water reclamation plant and the underground effluent disposal system. We are also preparing an operation and maintenance manual and will conduct an operator training program prior to plant startup. on WASTEWATER RECLAMATION r CLIENT: Government of the U.S. Virgin Islands St. Croix, U.S. Virgin Islands Due to St. Croix's location, topography, and climatic conditions, it lacks a sufficient supply of freshwater. Rainfall, although averaging 40 inches (100 cm) annually, is rapidly lost by evapotranspiration and is unevenly distributed both geographically and seasonally. Complicating this situation is the fact that the islands are subject to both flash floods and long periods of drought. Until 1968, most drinking water was collected in cisterns, which store runoff from the roofs of houses, or obtained from some ground -water development. Since 1968, numerous seawater desalination plants have been constructed on the islands, and they now supply most of the public potable water in the Territory. This water is expensive, costing $6 to $20 per 1,000 gallons ($1.50 to $5.25 per cubic meter), and the plants often experience mechanical failures. CH2M HILL was retained to explore wastewater reclamation as a means of increasing the available ground water and protecting it against saltwater intrusion. In order to offset the high cost of. desalinized seawater, a portion of the domestic wastewater produced in St. Croix is processed in an advanced wastewater treatment (AWT) plant designed by CH2M HILL and then reused for a variety of purposes. These have included increasing the ground -water supply through artificial ground -water recharge, agricultural irrigation, and mariculture. CH2M HILL designed this o.5-mgd (1,630-ms/day) AWT pilot plant, whits is used to reclaim wastewater for further beneficial uses. The reclamation plant is located on St. Croix's semi -arid south shore. I During the period 1971 through 1975, we performed hydrological investi- gations, designed the AWT plant and artificial recharge areas, supervised construction, and then operated the plant and recharge facilities for over a year. Extensive data were gathered on various aspects of the project, and local personnel were trained in facilities operation. In 1975, both the operation of the facility and the trained personnel were transferred to the Virgin Islands Government, which is in charge of operating the project. One possible use of treated effluent from the reclamation plant is for the irrigation of forage crops for the Virgin Islands cattle industry. U 1313 ROCK CREEK ADVANCED WASTEWATER - 0 1313 TREATMENT PLANT.:. El C` 4 CLIENT: Unified Sewerage Agency Washington County, Oregon At groundbreaking ceremonies for the Rock Creek plant, the LIlate Burt Wilson Jr., then chairman of the board of the Unified Sewerage Agency (USA) gave the principal address. He de- scribed the plant by saying "... (it) is a real winner for the a environment, and the way it is being designed and constructed is a real victory over inflation." By providing a high degree of wastewater purification, this regional treatment plant will protect the environment and set the stage for orderly growth in the 33,000 -acre Beaverton -Rock Creek Basin. In addition, phased design and construction methods are saving taxpayers more than $1.5 million. The Rock Creek plant, a major part of USA's 10 -year master plan for wastewater management in Washington County, will treat a maximum flow of 45 mgd. Average design flow is 15 mgd. Secondary treatment is provided by the high -purity oxygen activated sludge process. During the dry summer months, secondary effluent is further treated by chemical precipitation and mixed -media filtration. Rock Creek advanced wastewater treatment plant. I Waste organic sludges are anaerobically digested and trans- ported by truck for application to local agricultural lands. During wet winter months, when land application is not possible, waste sludges are dewatered in a filter press system and placed in a sanitary landfill. This is the first EPA -funded wastewater treatment plant designed and built using construction management techniques. Under this phased design and construction system, portions of the project are built while other portions are still under design. Construc- tion of the $20 million plant is scheduled for completion in October 1977, more than 9 months earlier than possible with the traditional design -bid -construct sequence. CH2M HILL's Construction Management Services (CMS) group ' has comprehensive project responsibility, coordinating all activities of contractors, suppliers, and the CH2M Hill design team. During the planning phase of this project, CH2M HILL assisted the Agency in facilities planning, site selection, and predesign studies. An environmental impact assessment and an infiltration/ inflow analysis were included in the facilities plan. UPPER OCCOQUAN SEWAGE AUTHORITY WASTEWATER RECLAMATION PLANT CLIENT: Upper Occoquan Sewage Authority 'Fairfax County, Virginia UOSA's 15.0-mgd Regional Wastewater Reclamation Plant. CH2M HILL has. provided complete services through the planning, design, construction, operator training, startup, and operations assis- tance. 7 2 i 3 r c R V 0 The Upper Occoquan Sewage Authority's (UOSA) $46 million advanced wastewater treatment plant went into operation in late June 1978, As a part of UOSA's overall Wastewater Reclamation Project, the plant is designed for the specific purpose of optimizing and conserving the area's total water resource potential. The plant is designed under the State of Virginia's "Occoquan Policy" to process wastewater flows of up to 15.0 mgd. Renovated wastewater, of near -drinking -water quality, is stored in a 55 -acre polishing impoundment. After storage, the water is released to Occoquan Reservoir, the source of raw water for over 700,000 people in the northern Virginia suburbs of Washington, D.C. The purification process used at the UOSA Wastewater Reclamation Plant includes activated sludge secondary treat- ment, phosphorus removal by lime coagulation, two -stage recarbonation, nitrogen removal by ion exchange, mixed -media filtration, activated carbon adsorption, and breakpoint chlorination. A central control system provides automatic process control along with data acquisition and reporting. Resource recovery and reuse are achieved by the use of ion exchange media, regeneration of carbon, and organic solids composting. The plant uses a closed -cycle ammonia stripping and absorption process for regeneration of the ion exchange system regenerate solution. The Ammonia Removal and Recovery Process, developed by CH2M HILL, recovers 40% ammonium sulfate for resale as an agricultural fertilizer. 7 I A composting system converts waste organic solids to a t stable organic soil conditioner suitable for recreational land rehabilitation or other agricultural uses. This project also includes the installation of 150,000 feet of interceptor sewers and force mains as well as six pump stations to deliver wastewater to the plant. CH2M HILL has provided all project engineering services through the planning, design, construction, startup, and operation of all project components. Total project cost is $83 million.

It was designed to play a major role in solving the wastewater treatment and water supply crisis faced by this suburban Maryland area near Washington, D.C. Montgomery County Advanced Wastewater Treatment Plant. Final design was preceded by a detailed site selection study, an in-depth pipeline and pump station route selection study for the interconnecting sewers and force mains, and a predesign report fully describing all aspects of the proposed plant. The estimated construction cost of the plant is more than $200 million. It is designed to provide up to 90 mgd of renovated wastewater of near drinking -water quality. The plant's peak hydraulic capacity is more than 130 mgd. The design provides for oxygen -activated sludge secondary treatment followed by phosphorus removal with lime coagulation, two -stage recarbonation, mixed -media filtration, nitrogen removal by breakpoint chlorination, and activated carbon adsorption. The plant also features onsite cryogenic oxygen and sodium hypochlorite (chlorine) generation, lime recalcination, recovery and reuse of hydrogen gas and the gas resulting from anaerobic digestion, and carbon regeneration. A computer -based system provides complete process control and data acquisition. Organic sludge can be burned in the boilers of an adjacent power plant owned by the Potomac Electric Power Company (PEPCO) . Additional plans under consideration call for using the sludge to reclaim strip-mined lands or as a fertilizer. The innovative and unique aspects of the plant's various solids handling systems led to the use of a scale model as a tool in designing the solids processing building.

CH2M HILL has provided complete planning and engineering services to the Washington Suburban Sanitary Commission on this project, from preliminary studies through final design ®®MUNICIPAL AND INDUSTRIAL WASTEWATER' TREATMENT• CH2M HILL's services in the field of wastewater treatment range from project development through project design to postconstruction services. Computer modeling techniques can be applied to specific water quality and wastewater problems via a terminal linked to our computer network. During planning and project development, local goals and desires, financing methods, environmental and social effects, and long-range plans are taken into consideration. The steps leading to a cost-effective, municipal waste- water treatment system can include 201 and 208 planning as mandated by Public Law 92-500, water quality studies on receiving waters, bench - and pilot -scale treatability studies, environmental assessments, and computer simulation. CH2M HILL has a demonstrated capability in all of these areas. Municipalities are required to follow the EPA 201 planning process to qualify for 75% federal funding for the construction of wastewater treat- ment facilities. The 201 plan is a sophisticated master plan which is carried out in three distinct stages: Step 1, preparation of a facilities plan; Step 2, preparation of plans and specifications for recommended and approved wastewater treatment facilities; and Step 3, plant construction and startup, and preparation of an operation and maintenance manual. Our engineers have prepared state- and EPA -approved 201 facilities plans for both large and small municipalities. We have prepared numerous plans and specifications under Step 2 grants. In addition, as part of Step 3 grants, we have provided construction supervision and startup reviews and have prepared state- and EPA -approved O&M manuals.

The aim has been to free the farmer from his dependence on the hydrological cycle by providing him with the water he needs, when he needs it. Increased agricultural production is the promised reward. Irrigation systems, however, must be a part of overall water resource management. CH2M HILL has provided complete planning, design, construction supervision, and operator training services on irrigation system projects of all types and sizes throughout the country. Our agricultural engineers direct a multi- discipline team of experts with years of experience in irrigation system design. Our specialists include agricultural scientists, geotechnical engineers, and hydrologists. CH2M HILL complete surveying and photogrammetric services, modern DEC system 10 computer facilities, and specialized infiltration equip- ment provide key design support. Our clients' projects have ranged from the rehabilitation and expansion of existing. irrigation systems to the installation of entirely new systems. Our canal design capabilities include hydraulic and structural engineering, seepage analysis, and slope stability analysis. We have also provided design services for various types of penstocks, distribution systems, farm turnouts, sprinkler systems, pump stations, storage facilities, and instrumentation and control systems. - n .... rµ f ✓^'Tt r'� " I • . .

Irrigation District, one of 85 metered farm turnouts, designed to deliver 65 gpm/acre at 65 psi min. for irrigation and 45 gpm/acre at 45 psi for frost protection. Booster pump station designed to increase the pressure for the higher ground in the ' Shasta View Irrigation District's new sprinkler pressure distribution system. Our clients' storage facilities have provided full or peaking supply through on -channel, off -channel, open, and closed storage. Control system designs have included automatic, telemetry, and remote instrumentation. In addition, CH2M HILL provides complete design services on drainage projects for both large irrigation districts and individual farms. Investigations of soil profile, permeability, and water quality are included. For the Shasta View Irrigation District in Oregon, we designed the conversion of an old canal system to a completely pressurized underground pipe system. A total of 17 miles of pipe mains and laterals, a 3,400 -hp main pump station, and a 1, 245 -hp booster pump station were installed. The system is equipped with a traveling water screen to prevent sprinkler plugging by algae. For the Glenn-Colusa Irrigation District in California, CH2M HILL's design provided for the installation of four radial gate checks and the enlargement of five siphons on the District's main supply canal. We provided both design and construction management services on this project. As consultants to the Central Nebraska Public Power and Irrigation District, one of our first tasks was inventorying the existing irrigation facilities. The immediate problem was assuring the farmer an adequate, consistent supply of water. Presently, his water supply is inadequate and is supplied on a fixed rotation schedule. CH2M HILL's design, which includes 22 miles of canal enlargement, a 40,000 -acre-foot peaking reservoir, and a pump station to fill the reservoir, allows the District to serve the farmers on a demand rather than a rotational basis.

LIAISON Effective communication among the many agencies associated with the project is a vital component of the project. The project manager acts as a catalyst to ensure that all parties involved in project decision - making are working together on an informed basis. INTERPRETATION OF PLANS AND SPECIFICATIONS The project manager provides interpretation of al I contract documents. PURCHASING OF OWNER -FURNISHED EQUIPMENT Our project management can include vendor identification and equipment contract bidding prior to finishing the detailed design and/or selecting a construction contractor. This procedure is often used to minimize construction delays on projects with long -delivery equipment items. EXPEDITING OF EQUIPMENT AND MATERIALS The equipment procurement function does not end with contract award. The project staff works closely with the contractor to assure timely delivery of materials and equipment. I _ Foreground shows reinforcing steel for foun- dation of chemical contact unit. Background shows structural steel and chemical storage tanks for the chemical building at the Murphree Water Treatment Plant in Gainesville, COORDINATION OF SUBMITTALS AND SHOP DRAWINGS The project manager/resident engineer coordirates the submission, review, and document control of all submittals require: for the completion of a project. Although the designer maintains resuonsibility for technical review of such submittals, the project manager ensures that reviews are performed in a timely manner. PAYMENT AND CHANGE ORDERS The project manager/resident engineer coordinates the issuance of all required change orders, determines the v due of the changes in the work, and negotiates contractor fees. Each morrh, the resident engineer, in cooperation with the contractors, determines the value of the work accomplished during the previous pay period; he then processes the payment requests and prepares a recommendation for payment. The completed package is approved by the project mar iger and then submitted to the owner for current payment action. MATERIALS TESTING COORDINATION The project manager/resident engineer coordinates the work of laboratories in the inspection and testing of materials used in the construction. Reports of such laboratories are received and evaluated. ADMINISTRATION OF RESIDENT INSPECTION ACTIVITIES CH2M HILL maintains a staff of tra ned and experienced inspectors. Our resident inspectors work with the owner, project manager, project -design team, and contractors to ensure c )mpliance of the work with the contract specifications. The project manager makes periodic visits to the project site to observe the progress and quality of the work. ASSISTING IN FINAL INSPECTION Upon completion of the construction work, the project manager, the resident inspectors, and the design team, in cooperation with the owner, verify that all components of the work have been completed in accordance with the terms of the contract documents. Our project manager ensures that this insn tion has been done, and further ensures that all deficient items are corrected prior to processing final payment to the contractor. I® LAND GRADING SERVICES CH2M HILL offers services in all phases of land grading, including feasibility studies, soils investigations, surveying, design, and construction inspection. A staff that includes agricultural engineers, a landscape architect, soil scien- tists, agricultural scientists, surveyors, and agricultural economists provides a wide range of expertise for land grading projects. Our extenstive experience in irrigation system design is of particular value since land grading design must coincide with border or furrow irrigation system design. In addition to general consulting, CH2M HILL offers a land grading computing service to farmers, consultants, and government agencies who desire to do their own field and design work but want to utilize our sophisticated method of computation. A computer program that offers many advantages over conven- tional hand calculations is used to make the computations. The program is highly accurate and provides flexibility that allows selection of the most de- sirable design. Uses of the program, other than for agriculture, include ath- letic fields, parks, and municipal and industrial plant site work.

The main features of the computer program are: .N Basic input is data describing the topography of the area to be graded. This may be from a field survey or, for preliminary work, by digiti- zation either from existing maps or during the initial mapping process. Acceptable grid intervals are 200, 100, 50, 10, and 2 feet. ■ Any number of fields can be defined within the area to be graded. Irregular field shapes and portions of grid squares adjacent to field boundaries are accurately accounted for. ■ For each field a plane can be computed that is either the "best fit" or that meets specified constraints. Constraints that may be varied are irrigation slope, cross slope, cut/fill ratio, waste, and borrow. ■ Preliminary output summaries show total cut, slopes, and other para- meters from which the designer may decide to either proceed with final output or to change constraints or field boundaries and run the analysis again. ■ Final output includes either data in a printed field note format or a plotted map showing field boundaries and the grading data at grid intersections. The cost of the computing service alone is generally between $1 .00 to $3.00 per acre. Costs are dependent on the type of output desired, size of fields, and the number of alternative designs considered. The cost of other land oradinq services varies with the scope of work and must be estimated on an •• LAND APPLICATION OF LIQUID AND SOLID WASTES MUNICIPAL WASTEWATER PROJECTS U.S. ARMY CORPS OF ENGINEERS FORT ORD, CALIFORNIA• Deep -well injection and irrigation were evaluated as poten- tial methods for disposal of 4.25 mgd of secondary treated domestic sewage effluent.

J 7-7 ■■ LEESBURG WASTEWATER TREATMENT ■i PLANT AND EFFLUENT IRRIGATION SYSTEM CLIENT: City of Leesburg, Florida With a 1980 population of 13,229, Leesburg, Florida, can still be classified as a "small" city. However, like several other small cities in central and north Florida, Leesburg is expected to continue growing, primarily because of migration from northern states and from southeast Florida. Located on an isthmus between two large lakes (Griffin and Harris) and 40 miles north of Disney World, Leesburg has many features, in terms of climate, outdoor recreation, and proximity to attractions, that will stimulate future growth. To provide for its inevitable growth and to minimize impacts on its natural environment, the City in 1970 began exploring ways to improve its waste- water treatment plant and to discontinue the practice of discharging treatment plant effluent to Lake Griffin. These efforts culminated in the improved 3.0 -million -gallon -per -day (mgd) secondary treatment plant and new effluent irrigation system, designed by CH2M HILL in 1978, which began operation in January 1981. The current system represents a major step forward in the history of Leesburg's wastewater treatment and disposal facilities. Modifications to the original system began in the 1940's with the installation of an Imhoff tank, followed by upgrading of the plant to provide 1.5-mgd primary treat- ment in 1955. Then in 1967, 3.0-mgd secondary treatment capacity was added in the form of aeration and clarification components. .t .. .mow - .., •y.. h+ ..YM1•T--I—, 1, �atih �,a\wi. \, •-w•., i i .. ulf' i•3•�\J •i. --.'•_-t i! �• •!ti/./.f4 ii i Lh A.fMN-L.a-u•-.� !_Lna_\.. i_.. - :i—/—.6, 02 • Irrigation site resery air. The EPA grants received by the City beginning in 1976 for a 201 Plan eventually paid 75 percent of the costs to upgrade the 1.5-mgd pretreatment units to a firm 3.0-mgd capacity and renovate several deteriorated structures, most notably the earthen aeration basins and their associated berms, which were eroding. Other plant improvements included a new 50 -foot -diameter digester, 10 sludge drying beds, and a new chlorine handling building. Finally, the existing lab and office building was expanded and the control room upgradedwith new monitoring equipment. The plant's effluent was diverted away from Lake Griffin by pumping from the plant to a 915 -acre tract of land 8 miles west of the plant. Within the site, approximately 330 acres are irrigated with the plant's effluent. This effluent irrigation system is currently the largest solid set (fixed gun) system in the state. It consists of a 10 -million -gallon reservoir, 6,400 -gallon - per -minute (gpm) pumping station (three 300 -hp vertical turbine pumps each rated at 3,200 gpm), 44,000 feet of buried irrigation pipe ranging in size from 24 -inch- to 6 -inch -diameter, and 83 irrigation guns (each rated at 620 gpm at 80 -psi nozzle pressure). Because of the seasonally high water table, approximately 100 acres of the irrigated areas are provided with subsurface drains, which deliver ground water to an onsite pump station, which in turn pumps the water to offsite drainage paths. The irrigated areas are planted with Coastal Bermuda grass, which is harvested by City employees using City -owned agricultural field machines and tractors. All of the effluent irrigation system was funded by EPA grants. The land was acquired with a 75 percent grant, while all construction items, including the transfer pumps at the plant, the 8 miles of 20 -inch ductile iron pipe necessary to reach the irrigation site, and all of the farming equipment received 85 percent EPA funding. p Ltanr N •I f ..

Pump station boosts pressure to distribution system after 7,900 -foot gravity flow pipeline to application site. An;imminent increase in sewer service charges prompted National Fruit Canning Co. (NFCC) to explore the alter.... •- natives to municipal treatment, Land application of seasonal pea and corn packing wastewater was selected. NFCC asked CH2M HILL to prepare plans and specifications on a crash schedule and to provide liaison for approvals from the Washington State Department of Ecology and the local County Planning Commission and Board of Commissioners. I. The process wastewater receives fine mesh screening prior to discharge into a 7,800 -foot gravity pipeline. The waste enters a flow equalization/emergency storage lagoon, and is ' later pumped into the irrigation system. Buried headers and portable aluminum laterals were used in this sprinkler irrigation system. I. Our work included soils investigation for hydraulic, organic, 6 and specific ion impacts. We designed the pipeline, storage 2 facilities, pump station, and portable distribution network. I2 C R P 0 n c I Because the effluent contained high BUD (1,600 to 2,600 mg/I),' TSS (400 to 800 mg/I), and sodium ion concentration, we proposed an irrigation system that basically limited hydraulic application to evapotranspiration requirements. Monitoring of sodium ion buildup in lower clayey soils was recommended. During the nonirrigation season, natural rainfall percolates through the soil profile to remove salts from the root zone. To control nitrogen leaching to the ground water, a Reed Canary grass crop is harvested annually and removed from the 60 -acre site. ' Our operating recommendations help to protect the site from excessive hydraulic and organic loads. The system is environmentally compatible with the surrounding wetlands area. I 1 C E is LAND APPLICATION OF TOMATO PROCESSING WASTEWATER CLIENT: City of Merced Merced, California To meet revised surface discharge permit standards for pH, nitrogen, BOD, and suspended solids, and to relieve seasonal overloading of their sewage interceptor system, the City of Merced contracted with CH2M HILL to investigate alternative means of handling and treating up to 5 mgd of process wastewater generated by a large tomato canning operation. During the canning season, flows from the cannery average seven times the volume during the noncanning season and are characterized by BOD values of about 1,500 mg/I, suspended solids concentrations in excess of 2,000 mg/I, and near -neutral to strongly acidic pH. CH2M HILL's facility planning and environmental studies recommended that the canning wastes be excluded from the municipal wastewater system and applied directly to preirrigate city -owned cropland. In comparison with other means of advanced waste treatment, land application provided the most cost-effective means of complying with the revised discharge standards and mitigating other problems associated with the cannery's high biological waste loads. rw •�YJ �y�q'{�i��i•f'1'� ' Y� .

This was successfully done by deep plowing to mix soil layers, addition of gypsum to improve soil chemistry, and extensive earthmoving followed by land planing to provide the required finish grades for efficient application. Facilities to accommodate wastewater application consist of ' seven 80 -acre surface -irrigated fields, pump stations, wastewater delivery and return flow systems, and ground- water monitoring wells. CH2M HILL provided complete design services and construction inspection for the pumping, distribution, and monitoring facilities, and for sitework associated with the project. A detailed site management plan and operation and maintenance manual were prepared to assist in the operation and maintenance of the land application treatment system, and to define the ongoing soil and ground -water monitoring program. Comparisons by the City show that the annual costs to operate and maintain the land application facilities are substantially less than the cost for treating the same volume of wastewater in the municipal treatment plant. Based on experience gained from site management and crop yields to date, the City anticipates that the site's gross operating cost will be reduced about 40 percent annually through the sale of oat hay and grain crops. Monitoring of site soil and ground water indicates no signifi- cant changes from preproject conditions as a result of wastewater application to the site. The site was prepared by deep plowing to mix the soil layers and improve soil permeability. ■s LAND APPLICATION OF FOOD PROCESSING WASTEWATER CLIENT: McCain Foods Ltd. Washburn, Maine This client processes Maine potatoes, producing various con- venience foods. As a result, up to a million gallons of nutrient - rich effluent is discharged daily from the plant. Until recently this flow was returned directly to the river. The consequent surface water degradation downstream was threatening to reach excessive levels. From wastewater management studies conducted by CH2M HILL, the client determine the best practical solution to be a multi- purpose treatment and land application operation. CH2M HILL• prepared the conceptual and final design for the new project and the construction surveying for the land application facilities. By means of a pipeline system controlled at the plant, the waste effluent, bearing dissolved and suspended material, flows approximately 4 miles where it is used for flood irrigation of 160 acres of grass hay. Site prior to construction of Land Application facilities. The initial study of the land application system included investi- gation of soil properties and geologic and ground -water charac- teristics to assess subsurface flow and permissible nutrient and hydraulic loading rates. The final design called for strategic location of seven observation wells to permit monitoring of ground -water levels and collection of water samples for chemical analysis. a I The extremely cold winter climate in northern Maine required special considerations. The design included allowance for 3.5 feet of ice buildup on the leveled fields and a subsurface drain line and pump station to remove the percolating water so that an unsaturated rooting depth of 3.5 to 4 feet can be maintained during spring thaw. Discharge from the subsurface drain line will be sampled and tested as part of the monitoring program. Because of the absence of well defined state requirements, close contact with state health and environmental agencies was main- tained during design. Support information for design criteria was supplied to these agencies. I I ®® WASTEWATER IRRIGATION OF MINT CLIENT: City of Junction City, Oregon Using its seasonally high summer effluent flows to irrigate a mint field, the City of Junction City has found an alternative to construction of $2 to $3 million worth of new sewerage facilities. The project was created by the need to dispose of ever- increasing volumes of effluent. The City treats its effluent in lagoons which discharge into a nearby stream. Between November and June, the flows in this stream are large enough to permit adequate dilution of the effluent. But during the summer months, low creek flows require that discharge from the lagoons be halted. The problem is compounded by increased summer wastewater flows from a major cannery. Since the lagoons have adequate organic treatment capacity, the City wanted to continue using them as long as possible rather than build new facilities. They therefore retained CH2M HILL to help them develop an irrigation program for summertime effluent disposal. I 6 2 C 1 1 Junction City mint crop where wastewater effluent is used for irrigation. The first phase of our work consisted of determining the City's wastewater flow and its quality, evaluating the alterna- tives of using city -owned land or private land, and contacting local farmers to determine the availability and suitability of their land for effluent irrigation. After results were evaluated, we recommended that irrigation be initiated on a private mint field adjacent to the treatment lagoons. We then established irrigation site development requirements and worked with the City, the landowner, and the Oregon Department of Environmental Quality (DEQ) to set up a one-year pilot/experimental program. Mint was preferred over other crops because it requires large amounts of water and nutrients; therefore, the land area needed for irrigation is reduced. In addition, tempera- tures reached during distillation of the mint to an oil, part of the harvest process, are high enough to kill residual bacteria. As a result, the crop product is not adversely affected by the effluent, making mint an ideal crop for this method of effluent disposal. The City's project was the first one in the state to win DEQ approval for the use of wastewater effluent on a food crop. So not only has the City avoided the major expense of adding new treatment facilities to its system, it has also proven that effluent can be successfully used to irrigate mint. E30 LAND APPLICATION am OF RAISIN PROCESSING WASTEWATER CLIENT: FRESNO COUNTY PLANNING DEPARTMENT FRESNO, CALIFORNIA Bonner Packing Company, a raisin processor near Fresno, applied for a permit to expand their land application system to mitigate developing environmental problems on their initial 20 -acre site. CH2M HILL was retained to develop a wastewater management plan for the proposed expansion. The study involved a detailed surface and subsurface soil in- vestigation, evaluation of the interaction of the high strength wastewater with the soil, and the evaluation of potential waste- water pretreatment processes necessary to effect adequate treatment by land application. Potential in -plant process changes which could improve wastewater quality and the en- vironmental health aspects of land application of wastewater were considered. A cropping program required to remove Bonner Packing Company nutrients applied with the wastewater was also developed. land application site. .. _.__ - e rr.=alAe6.- ' e - .-.6 • • (-3ry-Ps'ti L__ .ssa sue.-rzw® eeP•e•.� _ -lS�"y`r•yy�, ^6 uo dl's 3 !

When the local farming community is participating in a reuse program, intensive marketing and public relations efforts are key elements. Such was the case in Salem, Oregon, where CH2M HILL developed a system to reuse nearly 7,000 dry tons per year of liquid, anaerobically digested sludge (marketed under the name "BIOGRO") on the croplands of participating farmers in the area. Public relations and marketing are also key factors in a similar sludge reuse plan developed for Madison, Wisconsin, by CH2M HILL. In a system developed by CH2M HILL for Denver, Colorado, liquid digested sludge will be piped to a 2,000 -acre drying and distribution center located 25 miles east of the city. Dried sludge will be marketed as a soil conditioner. In Virginia, for the Upper Occoquan Sewage Authority, we conducted alternative evaluation and site selection studies for a composting/land application program.

The program involved more than six months of intensive study and planning by the City and CH2M HILL. By completing the $18.5 -million expansion project at Salem's Willow Lake Wastewater Treatment Plant, this system will recycle about 6, 750 tons of dry solids each year. Liquid sludge, anaerobically digested, will be spread on the crop- lands of participating farmers in the area. Semi -tank trailers will haul the sludge, and specially designed swamp buggies will spread the liquid sludge. To develop this sludge -reuse system, we studied soil and crop suitability and designed an extensive system for moni- toring sludge, soil, crops, and ground -water characteristics. An innovative marketing and management program developed by.CH2M HILL to promote "BIOGRO,"is a key factor for its success. Liquid sludge, anaerobically digested being spread on croplands. ®■ METRO !E SLUDGE DENVER MANAGEMENT PROGRAM CLIENT: Metropolitan Denver Sewage Disposal District No. 1 Denver, Colorado A 25 -mile -long transport system, featuring some of the longest sludge transmission pipelines in the United States, is one feature of the District's innovative sludge management program. This program provides for the reuse of 1 mgd of waste organic sludges (at 3 percent solids content) from the Metro Denver Sewage Treat- ment Plant. A $32 million, CH2M HILL -designed expansion project has added about 70 mgd to this plant's treatment capacity. The dual pipeline system delivers the sludge to a 2000 -acre drying and distribution center. Here the sludge is air-dried and stock- piled.prior to marketing as a soil conditioner. The drying center will also have areas for demonstrating surface and subsurface sludge application methods. These methods will be demonstrated for both dryland and irrigated farming. The key to this project's ultimate success lies in the District's extensive marketing program, begun well in advance of actual system operation. When the. benefits of this marketing effort are fully realized, the drying and distribution center will become one link in the ultimate reuse chain. An artist's rendering of the District's 2000 -acre sludge drying and distribution center Runoff from the entire site will be collected and stored. When its quality is acceptable, it will be released to nearby drainage - ways or reused for irrigation. An extensive system of wells will monitor ground -water quality. CH2M HILL assisted the District in the development of this system, from initial studies of sludge management alternatives through design of the selected agricultural reuse plan. Site selection and identification, fertilizer market analysis, and an environ- mental assessment were major elements of preliminary studies.

Through implementation of this plan, liquid, anaerobically digested sludge will be applied to agricultural lands as a fertilizer and soil conditioner. Loading sludge to be distributed and applied to local farmland, part of a proposed sludge reuse program. To ensure the success of its plan, MMSD has embarked on an extensive marketing and public information program that is de- signed to promote public acceptance and gain the support of the local farming community. The MMSD's 36-mgd wastewater treatment plant is being expanded to treat the 50-mgd flow predicted for the year 2000. By then, sludge production will have increased from the present 5,000 dry tons per year to an estimated 7,000 dry tons per year. In addition, a 135 -acre lagoon, in use for 35 years, contains about 90,000 dry tons of sludge that must be disposed of. u i ft Sludge- inlectan tractor for applyin- sludge to farmland Rryht Liquid sludge diarnuliun and land - oplIca Ion systems tor i 15D f9rJ `�[� � �.' i Jr �i'Y1 _ r 'ate '� -• ..�s-', v. \t .l :•�l`Q�'A. ` \�:'_\ter . ..:. ' To find the best ultimate disposal method, the MMSD did a comprehensive study of the various alternatives. After deciding on a land application system, the MMSD retained CH2M HILL to develop a reuse plan that could be implemented in the Madison area. The resulting plan provides for a long-range land appli- cation system and calls for removing the lagQoned sludge over an 8- to 10 -year period. Eventually, the lagoon area will be re- turned to its original marshland condition. Because the sludge lagoon dikes were showing signs of failure, immediate corrective actions were necessary. CH2M HILL geo- technical engineers recommended a unique, economical, repair method. All told, the dike rehabilitation project will cost the MMSD about half as much as has been predicted by the lowest of several previous estimates. In the development of this sludge reuse plan, CH2M HILL worked with the MMSD in formulating operation, management, and moni- toring procedures and public information and marketing prnnrams. Meetings were held with the farm community to outline the pro- posed reuse plan and obtain farmer input. Specific tasks included the determination of present, and probable future, sludge character and volume; a review of pertinent local, state, and federal regulations; soil, ground water, and crop suitability surveys; and an evaluation of reuse program alter- natives based on site location, sludge application rates and distri- bution methods, and local acceptance. I II • A.; 4-a Compost shredder The UOSA composting system follows this operational sequence: Anaerobically digested sludge is conditioned with ferric chloride and lime, then dewatered to 40 percent solids using a 2- by 1.5 -metre, 114 -chamber plate and frame filter press to yield 25 cubic yards of sludge cake per day. It is then hauled by truck to the onsite 220- by 350 -foot composting building and unloaded in windrows. A self-propelled composter is driven over each windrow, initially to blend the new material with recycled compost used for bulking and drying, and later to provide periodic mixing and aeration. The composting process creates temperatures up to 150°-170° F which destroy pathogenic bacteria and parasites. Regular tests confirm the removal of these organisms. A completely stabilized compost is produced in three to five weeks. CH2M HILL recommended the windrow method of compost- ing based on our research at two successful sludge composting operations for the U.S. Department of Agriculture's Experimental Station at Beltsville, Maryland, and for the Los Angeles County Sanitation District. Several modifications to conventional composting techniques were made to take into account the operational features and environmental characteristics of the UOSA facility and its location. Rather than taking place outside, the composting occurs in a covered area, minimizing the effects of rain, wind, and snow. This permits bacterial activity to occur more quickly and facilitates equipment operation for pile turnover. The compost building itself incorporates some unusual features. The floor slopes in two directions, incorporat- ing peaks and valleys to facilitate drainage. It also includes a drainage system that feeds liquids back to the treatment plant and a corrosion -resistant fiberglass air handling system used to keep each windrow in an aerobic state. The system became operational in January 1979. When landscaping demands for compost at the plantsite have been completely met, the Authority will make available 22 tons of compost produced daily to the Fairfax County Park Authority and the Northern Virginia Regional Park Authority for nursery use and recreational athletic field rehabilitation purposes.

HR SEWAGE PUMP STATIONS (UP TO 55 MGD) m Sewage pump stations are an integral part of most municipal sewerage systems. The topography of densely populated areas does not normally allow transport and treatment of sewage completely by gravity. Pump stations designed to lift the flow are located at appropriate locations in the system to provide the most efficient transport and treatment. CH2M HILL offers complete services for the development of sewage pump stations, from conceptual planning through final design and construction management. Each project is staffed with sanitary, mechanical, electrical, hydraulics, structural, and geotechnical engineers to form a multidiscipline team. Complete design includes soils investigations and excavation dewater- ing system design where necessary. The project manager is the team leader and is responsible for the project from initial conception through final con- struction. We have worked with large and small municipalities, sanitary districts, and industry. Pump station projects have ranged from small 100 gallon per minute package stations to stations with a hydraulic capacity of over 100 million gallons per day. All stations include controls to match pumping rates with influent flow. This is normally accomplished by on -off control in small stations; however, the larger stations include variable speed drives and controllers to provide continuous discharge matched to influent flow. Most large pump stations also include emergency power generation equipment for standby operations. A brief description of several of the pump stations recently completed by CH2M HILL follows. - (over) ___ - - -I-. Ii r 1 ft -,4 • {j It! .1 ycY.c'•• �w •�.'

The Boeing Company's 747 plant and John Fluke Industries (an electronics firm) are located in this area, and city planning policies will concentrate most of the city's future industrial growth there. The service area includes a popu- 7 ' - lation of about 60,000, with a population of 257,000 projected for the year 2 2030. The interceptor is sized for ultimate peak flows and will convey sewage 7 to existing treatment lagoons eight miles away in Northeast Everett. The '3. interceptor system will be extended into South Everett in 1990. 2 c CH2M HILL provided complete services to the city, including studies, pre- • a liminary and final designs, permitting assistance, cost estimating, soils in- vestigations, surveying, mapping, easement preparation, and inspection ' and services during construction. We also assisted with formation of the ULID and participated in public information meetings. Total time for planning, ULID formation, design, and bidding of the project was approx- imately 18 months. I Five major components comprise the project: • The Mukilteo Beach Interceptor, 3.1 miles of 16" to 30" gravity -pressure ' sewer at the upstream end of the project, is located in the tidal zone along a saltwater beach parallel to an existing sewer. Limited working time and space in the tidal area and corrosive beach sands present unique design and construction problems. • The Southwest Interceptor, 2.5 miles of 30" pressure and gravity - pressure sewer, carries the sewage across the city over a 170 -foot - high ridge. This required trench depths to 25 feet and extensive sur- face restoration of city streets filled with existing utilities. • The South End Interceptor, 2.3 miles of 42" and 48" gravity -pressure sewer, conveys the sewage the remaining way to the treatment la- goons. Much of this segment is built through soft, organic soil and wood waste with a high water table. It also includes a 500 -foot -long underground crossing of the Snohomish River. • Pump Station No. 1 boosts the sewage from the Mukilteo Beach Interceptor into the Southwest Interceptor, utilizing five variable -speed pumps to match the broad range of flows. • At the treatment lagoons, there is a new 125 mgd headworks facility. It includes four 84" diameter open screw pumps, three 10 -foot -wide mechanically cleaned bar screens, flumes for flow measurement, two 40 -foot -diameter grit collectors, and screenings and grit handling facilities. Along its entire length the interceptor required three highway crossings and 15 railroad crossings, most of which required jacking or boring. And although most of the interceptor route is along public right-of-way, 15 to 20 easements to cross private property were required, along with 41 permits obtained from seven public agencies. Total project cost was $28 million, $17 million of which was funded by ULID assessments. I II 0o COMPUTER APPLICATIONS TO WASTEWATER MANAGEMENT The computer... that marvel of modern technology. Its speed and accuracy are truly amazing. Yet, any computer's usefulness is governed by the people who put it to work. CH2M HI LL's people have many years of experience in the development of computer programs that help solve wastewater management problems. We see the computer not as a do -it -all designer, but as a tool that we can use to save time and money for our clients --both large and small. Engineer reviews plotted output produced by design program. 71 2 7 3 C 6 E V 2 A The computer's applications to wastewater management problems are many, from facilities planning through collection and treatment system design. Using the computer as a workhorse, CH2M HILL engineers _can complete tedious calculations and examine a host of alternatives rapidly. This allows us to select a design that is optimum in terms of both efficiency and cost. A computer model that we call SAM (Systems Analysis Model) was developed by CH2M HILL for detailed analysis of storm, sanitary, and combined sewer systems. It is straightforward and easy to use, yet technologically sophisticated. It may be the only model of its type that can be put to work by persons who are not computer experts or specialists in urban hydrology. Using SAM, we helped the City or Milwaukee, Wisconsin determine bottlenecks in their collection system and formulate control strategies to eliminate overflows. Artist's rendering of the Upper Occoquan Sewage Authority's regional advanced wastewater treatment plant in Fairfax County, Virginia. Computer modeling aided CH2M HILL engineers in the design of this 22-mgd plant. We have used the computer as a tool in treatment plant designs for both large and small clients in many states, including California, Idaho, Maryland, Washington. J/ (over) SAM is only one of the computer programs CH2M HILL uses to serve clients in the field of wastewater collection. We use others to design plot, and estimate the cost of storm and sanitary sewer systems. One CH2M HILL computer program has provided many of our clients with simplified cash -flow analyses through construction and financing periods. Like many of the programs we use, it is designed for use by clients without large staffs or access to complex computers. We have used computer programs to optimize secondary or tertiary treatment process designs for clients' plants across the country. Three examples are Montgomery County, Maryland; Denver, Colorado; and Washington County, Oregon. Another program, called HYDRO, has been used to provide thorough, accurate hydraulic designs for our clients' wastewater treatment plants. These are a few examples of the many ways that CH2M HILL uses the computer to better serve clients in the field of wastewater management. We maintain a library of nearly 400 general and special purpose computer programs in the sanitary, civil, structural, soils, architectural, mechanical, and electrical fields. CH2M HILL's modern, in-house DECsystem-10 computers are connected with our regional offices. • i - usinr, rn91Ruttr nrnr]r.r-i CIINt HILL tr13,neers ca'' r(r)idl'y' e<amnv many dlr- rflnt alts -r1 "I Pf and crIOCt .In rlp t I lrlll rtl Irei]n in torah of both etficicncy and Lt.

CH2M HILL's support capability extends from data acquisition and plant monitoring to supervisory and direct digital control. Areas of specialization include hardware interfacing, telecommunications, remote multiplexing, and software development. Examples of Computer -Based Instrumentation and Control Systems recently designed by CH2M HILL follow: Upper Occoquan Sewage Authority, Manassas Park, Virginia: The computer - based plant control system for this advanced wastewater treatment plant provides automatic data aquisitions; alarms, feed forward, feedback, and special control algorithms; maintenance scheduling; automatic backwash sequencing; electrical power consumption monitoring; cathode ray tube (CRT) operator consoles; and data processing and analysis. An analog control system provides backup on critical control loops. The remote sewage collecting and pumping system is monitored by an audio -tone telemetry system that is interfaced with the plant's computer complex. Metropolitan Denver Sewage Disposal District No. 1, Denver, Colorado: The instrumentation and control system for the expanded MDSS plant is computer -based with manual and automatic analog backup controls. Operator interface with the process is through CRT's or through panel instruments in the event of total computer failure. A dual computer arrangement with remote multiplexing was used. Each computer communicates directly and independently with the field multiplexer assemblies, allowing complete redundancy for the primary computer and its communication equipment out to the field multiplexers. z' g A V Metro Denver Control Center is C, a E Denver Board of Water Commissioners, Denver, Colorado: The Foothills Water Treatment Plant contains a hydroelectric generating station and provides a treatment process consisting of chemical coagulation, sedimentation, filtration, and disinfection. I Operator interface with the process is through CRT consoles or through the in -panel instruments in the event of computer failure. Provision is made for future microwave telernetering equipment that will allow communica- tion with a central facility in Denver for transfer of plant flow and water quality information and, eventually, for limited plant supervisory control. A unique feature allows manual backwashing of any filter at the filter location through a hand-held computer terminal communicating with the computer system over the in -plant phone systern. Water and Sewage Authority, Trinidad and Tobago, West Indies: This water system, which includes six pump stations, a water treatment plant, 15 reservoirs, and a force main system, is provided with computer -based supervisory system with radio telemetry. The central supervisory system provides data acquisition, display, alarming, and remote manual control in real time and data processing in the background mode. ii ENERGY MANAGEMENT• Just as it is necessary to approach decision -making about finances, personnel, facilities, and material use in a logical manner, it is necessary to make reasoned decisions for efficient energy use. CH2M HILL can assist you in gaining firm control of the energy flow of your facility and operations through the ENERGY MANAGEMENT PROCESS. Our energy managment team --mechanical and electrical engineers, economists, and planners --is experienced in the tasks required to develop an energy management program for your organization. Beyond developing and implementing an energy management program, CH2M HILL designs energy -efficient new construction and engineers energy -efficient retrofits. Our capabilities include cost estimating, value engineering, detailed design and specifications, construction management, system startup and adjustment, preparation of training and procedure manuals, and followup monitoring of system performance. We can aid you in developing a management framework suitable to your firm that will include: • An energy accounting system ■ An employee/operator involvement program ■ An audit and subsequent analysis identifying: No- or low-cost energy conservation measures Quick payback energy conservation measures Capital investment energy conservation measures ■ Procedures to comply with new and upcoming government and utility rules and regulations ■ A forecast of fuel costs and availability ■ Emergency curtailment plans ■ Recovery of resource material from scrap ■ Use of cost-effective renewable resources 4 ii INSTRUMENTATIO N CONTROL SYSTEMS AND DESIGN To meet the increasingly varied needs of industry and utilities, CH2M HILL has developed a wide range of expertise in the area of Instrumentation and Control. At present, CH2M HILL. has some 16 experienced I CC engineers among its 13 offices. We have specialists in virtually every facet of this discipline: analog systems (electronic & pneumatic), analytical instrumentation, electrical -systems (motor control), solid state logic, programmable controllers, process control computer systems, telemetry, multiplexing systems, and systems engineering. We have many years of experience in designing total systems for industry, military, and municipalities. As these various projects dictate, virtually any degree of detailing can be provided by the CH2M HILL I & C staff, from functional specifications to detailed component design or procurement and "hands on" implementation in the field. Examples of Instrumentation and Control Systems recently designed by CH2M HILL follow: Tahoe -Truckee Sewage Authority, Tahoe Vista, California: Advanced wastewater treatment plant with all electronic control system.

ENGINEERING Teamwork is basic to the concept of value engineering (VE). Today, design architects, engineers, and owners must work together efficiently to achieve a cost-effective, technically sound design. The goal of VE is to reduce not only capital costs but also operations, maintenance, and replacement costs. Through life -cycle cost analysis of designs, a VE study can significantly reduce overall project costs. CH2M HILL's professionals work directly with our client's staff or, if desired, independently to optimize life -cycle costs. VE is required on most large federally funded projects and is strongly recommended for most smaller projects. The Environmental Protection Agency; the Army Corps of Engineers; the Department of Health, Education and Welfare; the Veterans' Administration; the General Services Administration; and the Department of Defense all have active VE programs. CH2M HILL has been a leader in developing and implementing VE procedures for public projects funded by these Federal agencies, as well as for projects for private industry and municipalities. VE is not a traditional cost-cutting technique, although it is related to some systems used by thorough design engineers. Our approach to VE consists of a systematic five -step procedure that enables VE teams to 02 A. 2 •0 PO F av �? OO 0pat OO 002 /1 `02 `02 4 A.

TIME' POTENTIAL SAVINGS DURING LIFE - CYCLE focus on the costs of fundamental and secondary functions of a design. The objective is to revise, combine, or eliminate functions and find innovative solutions. While a design engineer not using VE methods will usually think in terms of the costs of alternative HVAC systems, a VE team will analyze many creative means of accomplishing the function "control temperature." This functional analysis technique allows the VE team to think in broad terms and consider such alternatives as building orientation, reflective roofing, and landscaping. The VE team spends most of its time examining basic functions that have a "high cost -to -worth" ratio, using a formalized, creative process to brainstorm alternative methods for achieving those functions adequately but more economically than the original design. The apparent viability of these ideas is tested by economic and technical feasibility calculations. Those ideas showing most potential for meeting functional needs and resulting in cost savings are developed to a predesign stage and pre- sented as alternative design proposals, along with a breakdown of life -cycle costs showing both capital and future savings. A decision board, composed of representatives from the client, the designer, and, if appropriate, regulatory agencies, weighs the merits of the proposals and decides whether to incorporate them into the final design. VE studies can be performed at any time during a design effort, but usually more savings can be made during the early stages of design, when the resistance to change and redesign costs are less. Most of CH2M HILL's studies start when design is 25 percent complete. Some larger projects may require several VE teams, working at different times and focusing on portions of the design. - Over 250 members of CH2M HILL's staff are familiar with VE methodo- logy and have actual VE project experience. All our VE team coordinators and team leaders are experienced design professionals who have attended authorized VE-training workshops. As a result, our VE proposals reflect both value engineering and professional design expertise. Typical studies have saved our clients $20 for every $1 spent on the VE effort, while documenting our methodical design review procedures. ii PLANT OPERATIONS SERVICES 2M HILL's plant operations team pro- ed a full range of services at the City Colorado Springs' 30-mgd secondary atment plant. Efficient wastewater treatment plant operation is vitally important to effective pollution control, especially with today's increasingly complex treatment systems. To better serve our clients, CH2M HILL has developed a team of experts specializing in operator training, the preparation of operation and maintenance manuals, plant startup, and system troubleshooting. These experts -- a senior operations consultant and sanitary, mechanical, and electrical engineers -- have an abundant store of practical operational knowledge and experience. They have assisted clients in the operation of hundreds of plants, large and small, conventional and tertiary. They are often retained as independent operational consultants. Another testimony to CH2M HILL's expertise in plant operation is our assist- ance to State and Federal agencies in the preparation of manuals and guide- lines such as "Estimating Staffing for Municipal Wastewater Treatment Facilities," for the EPA and the State of Washington's "Wastewater Plant Operator's Manual." CH2M HILL's "plant operations" team offers the following services.

This included training the operational staff, both supervisory and general, supervising plant startup of all unit processes, and providing compre- hensive operations assistance service to the Authority during the first year of operation:' Treated effluent from this AWT .plant is discharged into the Occoquan Reservoir,' source of raw. water for 660,000 northern Virginians living in the suburbs of Washington, D.C. The effluent's near drinking water quality is achieved through unit processes which include: activated sludge secondary treatment; lime -treatment, recarbonation, filtration, nitrogen. removal by ion exchange, carbon adsorption, and breakpoint chlorination. Extensive redundant designfeatures are incorporated at critical mechanical and electrical points. Sophisticated duplicate computer systems -control and monitor chemical feeders, composite samplers, rapid mix and recarbonation pH, the aeration basins' dissolved oxygen, the filter back- wash cycles, and the sequencing of the ion exchange media regeneration system. Because of the complexity of the plant and the fact that it was a,totaliy new facility with no performance history, a two -phased training approach was planned and implemented. Phase .1 involved key Authority operations staff in a 10 -week training program acquainting them with the overall operation and maintenance requirements- associated with all treatment processes. Phase 11 provided the general staff with 5 weeks of intensive training in operatirigxand maintaining equipment associated with., one of- the;five:specific process groups to. which they were --assigned'. ,Th& five, process groups were conventional (primary -secondary). treatment, chemical treat ment, advanced• waste- treatment., organic and chemical solids handling, and pump stations. u Instruction techniques included classroom and hands-on sessions, with regular formal testing and informal review to assess progress. Teaching materials included a nine -volume OSM manual prepared by CH2M HILL. Key Authority staff were instructed by CH2M HILL design engineers. Upon completion of their indoctrination, the key staff were given the responsibility to instruct the general staff under the supervision of assigned CH2M HILL design engineers. Preparation of lesson plans by the key staff was part of their training program, a program modification that saved the Authority $25,000 in engineering fees. Copies of all training lesson plans, exhibits, and tests were left on file with the Authority to facilitate future training, 4 I LOSA ole rater (left) cad (1121,1 HILL e n(Ilneor mulet. chemlce: feet] systerr per to rnsmce.

CH2M HILL engineering staff members were responsible for supervising plant startup operations. Original plans called for a week of operating the facility with clean water. However, imminent discharge permit expiration at 11 plants being replaced by the new facility forced startup without clean water shakedown and before construction was completed. CH2M HILL responded to this stressed startup circumstance with an intensive program of equipment troubleshooting by each process group startup engineer. Additional instrumen- tation and control support was brought in to assist in control loop troubleshooting and tuning. Within 3 days of accepting sewage, the effluent from the chlorine contact basin was of noticeably high quality --turbidity was consistently below 0.4 NTU. Nevertheless, re -treatment of the plant effluent was instituted for 2 weeks to assess the operational reliability of the on-line equipment and determine the effluent suitability for discharge. Throughout the first year of operation, the facility maintained extremely high effluent quality without interruption. HR CONSTRUCTION COST ESTIMATING`4 66" diameter Trunk Sewer for the Seattle, Washington Storm Sewer Separation. � Yr: Repairing a Collapsed Quaywall at the Swan Island Ship Repair Yard, Portland, Oregon. CH2M HILL has estimated construction costs for a wide variety of projects during its working span of over three decades. Some examples are water and wastewater collection, treatment, and dispersion; transportation systems marinas, ports, bridges; energy development, transmission and distribution; industrial complexes; solid waste processing,- resource recovery, and energy production. The geographic area where we produce construction cost estimates is wide. Although most of the estimates have been made for projects in the 48 contiguous states, the firm has estimated construction costs in Alaska. Hawaii, the Caribbean, the Central Pacific, the Mid East, and the Far East. The types of estimates range from the conceptual, which is often used for comprehensive plans and predesign reports, to the most definitive type - the engineer's estimate, which is commonly used as a reference for comparing contractors' bids. The estimating staff also regularly produces estimates used during various stages of a study, design,or even during construction. Most of CH2M HILL's projects require estimates of construction cost and, as a result, a vast wealth of cost data has been accumulated. These data are regularly updated and easily accessible to our engineers, economists, planners, and scientists for their projects. As a part of Construction Management Services (CMS) , the estimating group provides technical assistance on studies, construction projects, value engineering, and construction program scheduling. .. 4 The Bellingham.

NO ENVIRONMENTAL CAPABILITIES CH2M HILL's environmental groups are structured to provide our clients with a comprehensive range of services. The firm can conduct small baseline studies or manage and carry out complex projects involving a variety of specialists. Our services include baseline studies, public involvement programs, and the preparation of comprehensive formal environmental assessment documents responsive to state and Federal guidelines. We also conduct specialized environmental studies in high technology areas. Facilities at CH2M HILL include in-house computer systems with ties to remote computer centers; technical libraries; complete printing facilities; and biological, soils, water, and chemical laboratories. We also have complete sets of equipment for air, water, geological, or biological field studies. An important adjunct to our environmental work are CH2M HILL's capabilities in aerial photography and photogrammetry. We own and operate our own aircraft and maintain extensively equipped laboratory facilities. Recognizing that today's projects require communication and interaction among diverse technologies, CH2M HILL is organized on the basis of mutually supporting technical fields. Typically, an environmental engineer, planner, or scientist has major responsi- bility as project manager and utilizes staff members from other fields to assist in various elements of the project. Occasionally, CH2M HILL retains outside specialists when knowledge of local conditions or need for special expertise is warranted by the needs of the job. The major fields involved in environmental assessments/ impact statements are briefly described below. ENVIRONMENTAL PLANNING CH2M HILL's Environmental Planning Group has successfully completed major environmental studies for a wide range of clients throughout the United States. These have included draft environ- mental impact statements, environmental assessments, and baseline studies: Projects evaluated include mining development; industrial sitings;. interstate and other highways; bridges; dams; hydroprojects; water supply and water resources systems; utility rate increases; power generation facilities; and electric, gas, and oil transmission corridors. The members of.the planning staff are highly skilled, holding degrees in architecture, engineering, the social sciences, and planning. This diversity of.background has resulted in strong, balanced, workable solutions to planning and environmental problems. ECONOMICS The Economics Grou• p is an integral part of CH2M HILL's environ- mental services. It regularly provides economic impact evaluations both as independent programs and as input to larger environmental impact and planning studies. These evaluations assess the primary • impact of project construction and the secondary impacts on the surrounding community in terms of employment and multiplier effects on spending. In addition to economic impact studies, the Economics Group offers comprehensive services including feasibility studies, regional and land economics, industrial development studies, market trend forecasting, rate studies, resources and energy economics, fisheries economics, and utility and transportation economics. ENVIRONMENTAL SCIENCES CH2M HILL's Environmental Sciences Group is staffed by experi- enced professional scientists and engineers in the fields of aquatic, marine, and terrestrial biology; fisheries; oceanography; chemistry; soil sciences; limnology; geography; aerial photo interpretation; geology; hydrology; climatology; and ecology. The group functions both as a service organization, supporting CI -12M HILL engineering projects, and as a complete environmental consultant to industries, municipalities, utilities, and state and Federal agencies. The Environmental Sciences Group conducts studies ranging from routine field surveys to special effects studies, highly sophisticated laboratory analyses, and computer simulation programs. The group is responsible for scientific analyses for environmental impact statements, wetland evaluation and enhancement, industrial process investigations, natural resources planning, fish hatcheries and aquaculture, air quality analyses, noise studies, wastewater discharge monitoring, testing for discharge permits, and testing related to pilot plant studies. Extensive field investigations for developing data bases are conducted when necessary. LABORATORY CAPABILITIES Modern, well-equipped testing laboratories form an integral part of CH2M HILL's complete environmental services. The firm's laboratories are located in Corvallis, Oregon; Redding, California; Montgomery, Alabama; and Gainesville, Florida. These laboratories provide facilities for air quality analyses, traffic noise evaluation, biological studies, bacteriological and chemical analyses, and soils testing. In addition, we have a biological taxonomy and testing laboratory in San Francisco, California, with supplementary aquatic and terrestrial laboratory facilities in other offices. ENGINEERING CH2M HILL's complete engineering specialties are available as needed for environmental studies. Our engineering capabilities cover virtually every aspect of the field. Environmental impact teams generally include our specialists in water supply and water resources development, waste systems, transportation and traffic control, noise and air quality control, industrial plants and processes, civil and structural engineering, electrical power systems, energy conversions, resource utilization, and conservation. COMMUNITY INVOLVEMENT Community involvement programs are required by an increasing number of agencies and are an essential part of CH2M HILL environmental impact projects. The approach is tailored to the needs of the project and community. A wide range of techniques has been developed, such as audio-visual aids, workshop meetings, special newspaper supplements, and use of public media. The purpose of the community involvement program is to obtain citizen's input early in the planning process to avoid last-minute adverse reactions that often result from inadequate or incorrect information. We have also had extensive experience in formal environmental impact hearings at local, state, and Federal levels.

The program's chief goals were to protect human and animal life from flood hazards and to improve and preserve natural. resources being threatened by erosion,. flooding, and degraded water quality. The County Office of Planning and Zoning retained CH2M HILL to assist in the preparation of the Severn Run Watershed Management Study, General Location Map of Severn Run Watershed. . - _. . Severn Run, the only stream classified as a recreational trout stream in the county, is the primary source of freshwater inflow to the Severn River, a tidal estuary of the Chesapeake Bay. The watershed comprises an area of approximately 24 square miles in the. northwestern portion of the county. Existing land use is predominantly forest and agriculture. 1 2 I boding of tievcrn Run on Dacus Mill Road. Arrow show. 100 -year flood ele atlon. Debris has it umulated downstream Irom dump. Because the project was the first of its kind to be conducted by the County, the study served as a prototype and assisted in identifying watershed management concerns on a countywide basis. The project's structure and success were certain to affect the public's and other government agencies' acceptance of the watershed management program. One of the most important elements of the program was the active involvement of a citizens advisory committee and a technical committee. These groups met with representatives of the County and CH2M HILL every 6 weeks during the effort's initial phases. Working with the citizens group and the County, CH2M HILL prioritized the problems that had been identified (flooding, erosion and sedimentation, and water quality degradation) and developed recommendations for their solution. This close coordination resulted in a watershed management plan that was both responsive to local needs and acceptable to the public. The Severn Run Watershed Management Study focused on four major problem areas: flooding, construction site erosion and sedimentation, stream channel erosion, and protection of water quality and the environment. To deter- mine the potential flooding problem, CH2M HILL simulated the watershed hydrology using the Soil Conservation Service's computer model T R20 for the 2-, 5-, 10-, 25-, 50-, and 100 -year storms. Water surface elevations for the floods resulting from these storms were determined using the Corps of Engineers' HEC-2 backwater hydraulic model for 22 miles of stream. Based on these model results, flood -plain maps for major streams within the watershed were prepared. These maps can be used to delineate the 100 -year flood plain for use in the regulation of development. At the County's request, CH2M HILL also conducted a critical, independent review of state and county ordinances relating to watershed management ordinances and developed recommendations for new county ordinances and improved methods of enforcing existing laws. One key result of the study has been the formation of a county program designed to continue implementation of the stormwater management recommendations developed during the study and to ensure that watershed concerns are addressed in future county plans. DC WATER QUALITY MANAGEMENT STUDY - 00 Yakima River Basin CLIENT: Washington Department of Ecology The Washington Department of Ecology selected CH2M HILL to develop a plan for managing the quality of water in the Yakima River Basin. The study was to evaluate the current water quality and to develop plans for improving the quality. Such plans would have to make recommendations for reducing the level of pollutants flowing from croplands, rangelands, feedlots, dairies, municipalities, and industries. •�tiM6.f �£+ .y�..��.

Samples for analysis were taken from return flows to the river, from the effluent from municipal waste treatment plants, and from the river. I Reports based on the study described the present water quality conditions in the basin and contain recommendations for improvements in municipal and industrial waste treatment; handling of runoff from feedlots and dairies, and recommended further study into ways of managing wastes from agricultural operations. I CH2M CHILL Wastewater Management ,r"' F71 i 'W " atZIMIN ! z - r 11 I I I 5, I I I 11 I I I I LI I I I I E I I CH2M HILL offers comprehen- 1 sive planning, design and project management services for the full range of wastewater system com- ponents —collection, transmission, ' treatment, and sludge and effluent disposal or reuse. Our reputation is based on over 30 years of provid- ' ing simple, cost-effective and easy - to -operate systems. In addition to offering personal knowledge of ' local conditions, each of our regional offices is able to quickly assemble a complete project team ' with access to the technical sup- port capabilities of the entire firm. For the small and medium-sized municipalities which make up the majority of our clients, this means getting the right skills at the right time to meet the particular de- mands of a project, no matter how large or small. Our experience with local reg- ulatory agencies, grant application procedures and funding priority lists allows us to assist municipali- ties with the project funding proc- ess. Our knowledge of regulatory requirements facilitates proper preparation of the necessary plans for agency review, saving clients ' both time and money. We also de- velop grant applications and, when desired, help administer grants. I I I I FACILITIES PLANNING CH2M HILL offers complete services for both EPA- and locally funded facilities planning projects. We efficiently carry out and coor- dinate the required studies and evaluations, allowing the majority of project dollars to be spent where they are most needed — solving our clients' specific waste- water system problems. Federal law requires munici- palities to submit an EPA- and state -approved plan to qualify for financing of major wastewater treatment facilities. These "201" facilities plans must include popu- lation and service area projections, :1 an infiltration/inflow (I/I) analysis, a public involvement program, an environmental impact assessment, and an evaluation of collection and treatment system alternatives. An I/I analysis consists of plant record reviews, flow monitor- ing and measuring at key man- holes, and computation of wet- and dry -weather flow ratios. These ac- tivities enable us to estimate the I/I in a system and compare the cost of treatment with the cost of sewer rehabilitation. If there is ex- cessive I/I, we conduct a sewer sys- tem evaluation survey, using our own staff or working together with the client, to analyze the problem in more detail, recommend correc- tive actions, and determine their costs and alternative cost trade-offs. w._ I I I I I H 1 1 1 1 1 1 1 1 1 1 I With experience in over 1,500 wastewater projects, CH2M HILL can quickly evaluate feasible alter- 'natives and concentrate on those that are most promising. Develop- ment of innovative/alternative so- 'lutions to wastewater problems has been a hallmark of CH2M HILL's services for years. Application of 'these technologies represents an opportunity to increase federal funding and can result in lower 'operating costs. When evaluating the suitability of such applications, CH2M HILL gives special consider- 'ation to simplicity and ease of oper- ation. Although we have applied advanced technologies to meet stringent discharge standards, cost- ' effectiveness and energy conserva- tion have been equally important in selecting appropriate treatment and disposal systems. In fact, the average CH2M HILL -designed We give special treatment plant costs less to con - Istruct than EPA's average of all consideration to consultant -designed facilities. cost-effectiveness As part of facilities plans, 'CH2M HILL formulates financial and ease of plans to determine the most suit- able means of funding wastewater operation. 'projects. Some plans are simple; others are complex, involving mul- tiple revenue sources. With our as- 'sistance, municipalities can more easily develop ordinances and pro- cedures to provide needed revenue 'to meet short- and long-term proj- ect expenditures. We help organize local improvement districts, publi- cize bond issue elections and pre- pare audiovisual presentations for use in public participation meet- ings. In addition to economic and ' financial services in connection with engineering projects, our eco- nomics staff can provide rate 'studies, cost recovery analyses and cash flow projections. J ,._ DESIGN SERVICES CH2M HILL has designed wastewater collection, treatment and disposal systems for munici- palities throughout the United States. On each project, communi- cation —the ability to both listen and respond —plays an important role. Our project team is headed by a manager who meets regularly with the client, creating clear lines of communication, efficient use of our capabilities and a thorough discussion of major decisions affect- ing final design. Collection Systems Sound design of pipelines is the foundation of our services on sewer projects. This includes selec- tion of materials and preparation of specifications, estimates and contract documents. We have de- signed, managed and inspected thousands of miles of sewers for municipalities and private devel- opers. We can also provide survey- ing, aerial mapping, geotechnical and environmental assessment services, and assistance with finan- cial arrangements. Pump Stations Pump stations are an integral part of many wastewater collec- tion systems. We offer complete services for the design of all types of sewage pump stations from package units to custom-built sta- tions. Our capabilities include surge analysis, odor control, soils investigations and excavation de - watering system design. Treatment Facilities Serving both municipal and in- dustrial clients, we have designed treatment plants ranging in size from 0.1 mgd to over 100 mgd. Our design approach uses innova- tive production techniques such as I I I Li I I I I J I I 'detailed design instructions, ad- vanced facilities predesigns, proc- ess and instrumentation diagrams, and operability reviews. Using these techniques, we formalize the details of plant operations before 'proceeding with final design. This approach allows us to complete the design with a minimum of last- 'minute changes while keeping the client fully informed. CH2M HILL has played a lead- ing role in the advancement of wastewater treatment technology. This experience is used to develop effective, reliable systems. In ' approaching a project, we careful- ly consider such factors as sewage characteristics, water -quality ob- 'jectives, reuse requirements, finan- cial capabilities, energy conserva- tion, environmental effects and the 1 practicality of modifying existing facilities. Solids Handling ' The overall success of a wastewater management program often hinges on the effectiveness 'of its solids management system. CH2M HILL has experience with all types of dewatering systems. I We have also recommended and designed systems for agricultural land application of liquid digested sludge. To achieve a successful re- use plan, we can develop market- ing programs and assist in estab- 'lishing delivery systems to trans- port the materials for reuse. Effluent Reuse 'In many cases, it is also feasi- ble to reuse the "water" in waste- water for beneficial purposes. 1 CH2M HILL has developed efflu- ent irrigation systems throughout the country. Our capabilities in - tclude feasibility studies, site selec- tion, environmental studies, agri- cultural development services, site 'management and monitoring, as well as preliminary and final design. Construction of the average CH2M HILL - designed facility costs less than the EPA average. I SERVICES DURING CONSTRUCTON CH2M HILL's services con- tinue through the construction phase of a project, when ideas and concepts are transformed into a completed facility. To help attain quality construction, CH2M HILL resident engineers and inspectors work diligently so that design con- cepts are accurately carried through to completion. We work with the owner, project design team and contractors to monitor compliance with the intent of con- tract plans and specifications. We also offer construction management services that speed up project completion by overlap- ping design and construction activ- ities. The level of our involvement in construction management is de- termined by an evaluation of the requirements of each project. OPERATIONS SERVICES No matter how well a waste- water facility is planned, designed and constructed, it still depends on proper operating procedures to function smoothly on a day-to-day basis. CH2M HILL performs plant evaluations and provides guidance in operator training, startup, opera- tions assistance, development of maintenance procedures and troubleshooting. In addition, our staff offers complete O&M manual preparation services.

In addition to the plant, the UOSA system incorporates 122,000 feet of gravity sewers, 31,000 feet of force mains and six pump stations. Mechanical, electrical and fluid systems at both the plant and delivery system pump stations were designed so that the failure of any component or unit would not interrupt plant operations critical to meeting the final effluent requirements. Three individual sources provide electric power to the plant and pump stations. The plant is supplied by two 69 -kV electrical feeders and one 2,500 -kW onsite emergency power generator. Each pump station has 100 percent pumping and control sys- tem equipment redundancy plus an emergency reten- tion pond with a capacity to hold a minimum of one day's average design flow. A computer -based central control system provides the plant with automatic data acquisition; alarms; feed forward, feedback and special control algorithms; pre- ventive maintenance scheduling; automatic backwash sequencing; electrical power consumption monitoring; cathode ray tube (Cr) operator consoles; and data processing and analysis. Supporting the central control system, and also providing backup, is an extensive elec- tronic analog sensor and control system. In addition to the in -plant instrumentation and controls, the remote sewage collection and pumping system is monitored by an and iotone telemetry system that is interfaced with the plant's computer complex (JOSA personnel use cathode ray tube consoles to monitor and control plant unit processes. Resource Recovery Features Removal, recovery and reuse processes built into the plant as part of the contaminant treatment system provide for three types of recycling: byproduct reuse, or- ganic solids stabilization and ammonia recovery. Methane and carbon dioxide gases, which are pro- duced as byproducts of biological processes, are re- covered and used to reduce fuel and chemical con- sumption at the plant. Methane gas produced in the anaerobic digesters is burned in boilers that supply heat to maintain the temperature of the digesters and to heat several plant buildings. Carbon dioxide gas (CO2), which is a byproduct of both anaerobic digestion and combus- tion, is compressed and used as a source of CO2 in the recarbonation process. Carbon dioxide is also recovered during the regeneration of activated carbon, com- pressed and used in the recarbonation process. The use of these gases produced onsite greatly reduces the need for fuel and commercially produced CO2. The sludge from conventional treatment processes is anaerobically digested and dewatered prior to com- posting. During composting, heat is generated by bacte- rial decomposition of the organic portion of the sludge. The sludge temperature rises to between 130° F and 170° F, effectively destroying most of the pathogens and parasites. Thus, a stabilized compost material is pro- duced. Approximately 11 tons of compost material are produced daily for use by local park authorities for nursery and athletic field rehabilitation purposes. UOSAs consulting engineers developed the Am- monia Removal and Recovery Process (ARRP) to re- move ammonia from the ion exchange regenerant solution and to recover it as a fertilizer product In this process, a 3 percent salt solution is used to regenerate exhausted ion exchange beds containing clinoptilolite media. The spent regenerant solution containing nearly 300 mg/I of ammonia is elevated in pH, clarified and pumped through ARRP modules. Each ARRP module consists of a stripping tower, which strips the ammonia gas from the spent regenerant solution, and an absorp- tion tower, where the ammonia gas is absorbed by a sul- furic acid solution to form ammonium sulfate. Approxi- mately 2,880 gallons of ammonium sulfate at 40 percent concentration are produced daily for use as a fertilizer in the agricultural areas of the region.

According to data collected by the Occoquan Watershed Monitoring Labo- ratory, required by the "Occoquan Policy" and operated by Virginia Polytechnic Institute and State University, the plant has already had a positive effect on the Occoquan Reservoir. During fall 1978, several months after startup of the plant, water quality in Bull Run, a tributary to the reservoir, was the best ever observed in the six years of the monitoring program. The impact of UOSA's project on the water re- sources of Northern Virginia is expected to increase if growth in the area occurs as projected. UOSA now has the means of protecting the reservoir from the effects of point source pollution while producing a significant sup- ply of reclaimed wastewater for reuse. WIomH'I111 ■ !'

The Willow Lake Wastewater Treatment Plant insures that area wastes will not degrade the river's clean waters. The Capitol building. The Salem area is one of the largest fruit and vegetable process- ing centers in the United States, processing some 10 million cases of canned foods and 260 million pounds of frozen food annually. This has been a tremendous boon to the Salem economy. It also has created a colossal waste disposal problem. Things went fine during most of the year when the City treatment facility had to process only municipal wastes. But during the three months when the canneries were going full steam, the load on the municipal treatment plant was sometimes six times what it was during the rest of the year. As fruit and vegetable processing increased, the City had to work fast to come up with solutions to a two- part problem: They had to develop a new facility capable of processing both large and small amounts of Oregon's capitol municipal and cannery wastes; and they also had to find some way to dispose of ever-increasing volumes of waste solids (sludge) that the treatment plant would produce. Therefore, the City asked CH2M HILL, consulting engineers, to study the problem, find the solution, and design a facility. The result is the Willow Lake Wastewater Treatment Plant, which makes use of the best practical technology available for treatment and disposal of combined municipal and food processing wastes. The ultimate in efficient and environmentally sound treatment and disposal... system —the heart of Willow Lake's treatment process. To take care of the treated solids disposal problem, scientists con- ducted an extensive soil and plant monitoring program to determine that processed sludge from sewage can be both safe and effective when used as a supplemental fertilizer. The sludge is marketed as "BIOGRO." It is delivered and spread on farms within the im- mediate area of the Willow Lake facility free of charge. The ultimate in efficient and en- vironmentally sound treatment and disposal of municipal and cannery wastes, Salem's Willow Lake facility is admired and copied by cities around the country. -♦lam • • r.I .' •, T• .. r.

I I I El I 'J I E L Typically municipal waste treat- ment plants dispose of treated waste solids by disposing of them in a sani- tary landfill or by burning them. At Willow Lake, nothing is wasted: Sludge is recycled into the soil as BIOGRO, and treated water leaving the plant is of such quality that it does virtually no damage as it is emptied directly into the Willamette River. The completed Willow Lake Wastewater Treatment Plant consists of a trickling filter plant (the North Plant) and a high -purity oxygen acti- vated sludge plant (the South Plant). The combined facility is designed to handle the anticipated wastewater treatment requirements of the Salem area through 1985. The design ensures that the facility can handle extreme seasonal increases result- ing from a three-month food pro- cessing season just as efficiently as it handles wastes during the noncan- NEADWORK5 PRIMARY -crVJC.n&TJ ( How it works. ning season. Incoming wastewater is split be- tween the North and South Plants. Two primary clarifiers at each plant remove settleable solids and floating material. The solids are pumped to a grit removal facility, where four cy- clone separators separate the raw primary sludge and grit. At the North Plant, effluent from the primary clarifiers is pumped to four trickling filters for biological treatment. Effluent from the trickling filters flows to the secondary clarifier where suspended solids are settled and removed. After chlorination, the treated wastewater is discharged into the Willamette River. The flow to the South Plant, after primary clarification, receives biological treatment in a three -train aeration basin. Each train has four cells, and each cell has a mechanical surface aerator to mix and dissolve oxygen into the wastewater. The S4LC44.w INFLUENT TANKS ---, -' 35aur�lvetgl�¢un�,q�n,1l��,��,. ypn,IaYu.

Effluent from the aeration basin is divided among four secondary clarifiers where solids are settled and re- moved. Most of this activated sludge is returned to the aeration basin and mixed with incoming primary effluent to renew the biological treatment process. Excess activated sludge is concentrated in either gravity or flotation thickeners. Thickened primary and secondary sludge from both plants is treated in primary and secondary digesters. The digestion process involves heat- ing and mixing in the absence of air. Volume is reduced and pathogens eliminated. The treated sludge is then ready for agricultural distribu- tion as BIOGRO. Methane gas produced in the process is used to heat the digesters and to produce electrical power for the plant. -3ELONDARY DI&E5TER5 DISINFECTION CHAMBER FINAL L 5EDIMENTATION TANKS BI0GRO DLS1 IBU [ION ID FARM CLEAN WATER To WILLAMETTE I VER The South Plant became operational in late 1976; the North Plant was com- pleted in 1964. The combined treatment facility represents the best practical treatment technology available today for removal and disposal of large volumes of suspended and dissolved pollutants from wastewater. Selection of the treatment process for the South Plant followed two years of extensive pilot plant studies. Large waste loads from local fruit and vegetable canneries and freezing plants mean that the treatment plant must, at times, handle six times the "normal" municipal requirements. Union Carbide's UNOX system, em- ploying high -purity oxygen to treat the wastewater, is the heart of the treat- ment process. Raw sewage pumps. Valve skid in oxygen control building. I BIOGRO (treated sludge) is loaded into tanker truck for delivery to farmers. One Salem area farmer who is a long-time user of BIOGRO aptly de- scribes Willow Lake's BIOGRO pro- gram as "completing the cycle: Bringing back to nature what was nature's in the first place." His statement couldn't be more accu- rate, because most of the wastes are from food processing plants. Salem's system of recycling these wastes has received praise from numerous environmental groups. Typically municipal sewage treat- ment plants concentrate sludge sol- ids and dispose of them in landfills, or burn them. But that's not the case in Salem. To date, 17 area farmers are fertilizing more than 1,600 acres with BIOGRO. Applications have been made to pastureland, nursery crops, berries, mint, grain, dill, orchards, hay, corn, and grass seed. Most use BIOGRO as a fertilizer supplement, but BIOGRO alone is sufficient to fertilize grass and grain crops. Bringing back to nature what was nature's in the first place. The City applies the material in liquid form at a rate of approximately 15,000 gallons per acre. The average per acre application includes 1,000 pounds of organic matter, 150 pounds of lime or lime equivalent, B*iogro Completes cycle. 75 pounds of nitrogen, 30 pounds of phosphorus and one pound of potassium. Applications have been made to pastureland, nursery crops, berries, mint, grain, dill, orchards, hay, corn, and grass seed. BIOGRO deliveries are made in 2,500 -gallon tank trucks called "bug- gies" equipped with sprayers that spread it uniformly in twenty -foot swaths. The buggies are equipped with extra -large tires to prevent soil compacting. City treatment plant personnel have been trained to do soil and plant sampling, laboratory testing, and record keeping. An ongoing and extensive monitoring program has been developed to insure that sludge applications do not become harmful to crops, humans, or the environment. Continued and fre- quent analysis is made of digested sludge, soils, crops, and ground water. 0 I John Weeks, a Salem nursery- man, is one long- time user who'll swear by BIO- GRO. He has used the material for seven years and says it has replaced cover cropping and liming on his 40 acres of nursery crops. "I think the whole country should be using as much of it (sludge sewage) as possible. It is a valuable resource that shouldn't be dumped or burned" Weeks says he has experienced no adverse effects over seven years of BIOGRO applications. He didn't have to add nitrogen to berries and rhubarb last year because of the nitrogen buildup from BIOGRO applications. He believes BIOGRO has reduced crown gall in berry plants, because the organic matter creates a healthy environment for a balanced ecology in which harm- ful organisms can't survive. Lyle Klampe, a local farmer and field representa- 'tP il tive for BIOGRO, says there is in- creasing accep- tance 1 by area farmers of the material as a fertilizer supplement. He foresees no difficulty in having sufficient land available to receive all of the BIOGRO the Willow Lake Plant can produce.

It is called "BIOGRO:' It has no additives or secret ingredients. It is simply the liquid digested sludge left over after waste solids have gone through the anaerobic digesters in Salem's Willow Lake Wastewater Treatment Plant. Salem farmers have found BIOGRO useful not only for its value as a fertilizer, but also because it contains substantial quantities of organic matter that condition and improve chemical and physical properties of the soil. BIOGRO supplies lime and nitrogen. A typical maximum application, the equivalent of two dry tons per acre, includes the equiv- alent of 75 pounds of nitrogen and 150 pounds of lime. BIOGRO also contains smaller quan- tities of phosphorus, potash, calcium, mag- nesium, sulfates, boron, copper, iron, manganese, molybdenum, and zinc. Early stages of dill field.

Design criteria The Willow Lake Wastewater Treatment Plant is designed to handle the needs of the Salem area and its local canneries through 1985. The treatment plant can handle wastewa- terflows up to 105 MGD (million gal- lons per day) and this flow rate serves as the basis for sizing major pieces of equipment. The solids produced in the treat- ment process and present in the raw sewage provide a second important parameter to be considered: Here, the plant must be capable of treating the peak loads expected during the three-month canning season.

Central Plant A complete expansion project. The Central Wastewater Treat- ment Plant's North Complex was originally built in 1966 to provide secondary treatment for metropol- itan Denver's wastewater. The need for additional primary and secondary treatment capabilities was identified in 1972. Construc- tion of modifications to the North Complex and design and construc- tion of the entirely new South Complex began in 1974 and were essentially completed in 1977. The South Complex now provides ad- ditional secondary treatment ca- pacity for the metropolitan Denver area. This expansion project, de- veloped by CH2M HILL, design engineers, will meet existing fed- eral and state effluent criteria well into the 1980s. The South Complex now will assist in providing secondary treatment for the metropolitan area well into the 1980s. Metro asked CH2M HILL to expand and upgrade the treatment capabilities at their Central Treat- ment Plant. The North Complex was modified to improve operation and maintenance. The South Com- plex is a new but smaller treatment plant adjacent to the North Com- plex. A bridge crossing the South Platte River was designed and built to provide primary access to the Central Treatment Plant facilities. The first impression the South Complex gives is its cleanliness. All the facilities were designed to be uncluttered and attractive. Four white towers reach for the sunny Colorado skies —two cryogenic oxygen generation towers cool liquid air to produce high purity oxygen for use in the aeration ba- sins while two store the liquid oxygen. Nearby, covered aeration basins aerate the wastewater on its way to secondary clarifiers. The covers on these basins are strong enough to support a mobile crane for equipment handling and the electric carts that are used for operations and maintenance chores. Tall black brick anaerobic digesters with white accent panels harmo- nize with the black and white clarifier tanks set into the ground. Effluent transport is done in under- ground channels. An addition to the administration building was designed to complement existing architecture while providing more office space, more room for lab- oratory testing of effluent quality and for process control. A ware- house and shop modifications were also added. An extensive computer -operated monitoring system takes care of many of the routine tasks so fewer operators are needed. A distinct advantage of the system is that better data are available for con- trol without requiring a large amount of time from operators or data -handlers. The project has extended the entire Central Plant's treatment capability by adding 42 million gallons per day (mgd) to existing primary treatment capacity, and the secondary treatment system can now treat an additional 72 mgd. An extensive com- puterized monitoring system controls treat- ment processes and generates and analyzes operational data to meet federal and state requirements. When the sludge drying and distribution center, 25 miles away, is completed, the Central Treat- ment Plant will be able to provide complete treatment at a 170-mgd annual average design flow — nearly twice the plant's original capacity. The entire construction project should be completed by 1985. 2. i, 1 C _ter The presence of protozoa such as this vorticella indicates a healthy condition in the aeration basins for successful treatment.

The new South Complex is shown in the foreground. Treatmen The treatment process. I I I I I II I I The high purity 'oxygen system at the South Complex does the same job as the 'North Complex in less space. Both the North and South Com- plexes provide primary and sec- ondary treatment and use the activated sludge treatment process. Diffused air aerates the waste- water in the North Complex; high purity oxygen aerates it in the South Complex. The Influent/Effluent Flow Raw wastewater enters the plant headworks, where the flow is measured by Parshall flumes and divided between the two com- plexes. It is then screened to remove coarse solids and rags. Sand, gravel, and other heavy inorganic particles are removed in grit chambers. Primary treatment is completed when clarifiers re- move settleable solids and float - able materials. Primary effluent is pumped to the South Complex facilities; it flows by gravity to the North Complex. Primary effluent from the City of Denver's Northside Primary Treatment Plant can also be split between the North and South Complexes. L I Secondary treatment begins in the aeration basins: Biologically degradable organic materials (measured by the biochemical oxygen demand, BOD) in the primary effluent are consumed by microorganisms in the presence of oxygen, synthesizing new micro- organisms and removing most of the BOD. This process is complete when the microorganisms floc- culate into a settleable mass (acti- vated sludge) and are removed in the secondary clarifiers. The cryogenic oxygen distilla- tion towers produce all the high purity (up to 95 percent) oxygen needed for biological treatment in the one large, eight -chambered aeration basin at the South Com- plex. Because of the high purity oxygen system, the smaller South Complex does the same treatment job as the North Complex's air system in less space. A portion of the secondary "ac- tivated sludge" solids are returned to the aeration basins to maintain a high concentration of biologically active cells to continue the proc- ess; excess cells are wasted to the sludge concentrator building. Finally, secondary effluent is disin- fected in a 2,000 -foot underground closed chlorine contact conduit and discharged to the South Platte River. Solids Handling Solids which must be disposed after treatment include screenings, grit, scum, and excess primary and waste -activated sludge. In the screenings building, screenings captured by bar screens and grit collected in grit basins are stored in hoppers. When these hoppers are emptied, the solids are hauled to an offsite sanitary landfill. Scum from primary clarifiers is pumped to hoppers to be hauled away by a rendering company for reuse. Settled materials from the pri- mary clarifiers are pumped to holding tanks to be transferred to anaerobic digesters for stabiliza- tion or to the vacuum filtration system for dewatering before dis- posal. Excess activated sludge from both the North and South Com- plexes is pumped to the sludge concentrator building to be thick- ened by flotation. The thickened sludge moves from temporary holding tanks to the anaerobic digesters. Anaerobic digestion reduces the amount of sludge for ultimate disposal and stabilizes it for agricultural reuse. The final solids processing step is anaerobic digestion. Eight 100 -foot -diameter, 32 -foot -high digesters hold the sludge at 95° Fahrenheit to stabilize it. Each digester uses the methane gas pro- duced from the sludge as its own fuel source. This process reduces the sludge volume by 50 percent and produces stabilized sludge for reuse. This stabilized product is recycled to the land for agricul- tural uses. r. IF S Y' - Above: Raw sewage enters the South Complex through the bar screens in the screenings building.

U;jIn the digester complex, methane gas produced by the decomposi- tion of sludge heats boiler feed - water, which in turn transfers heat to the sludge via heat exchangers. Anaerobic digesters complete the solids treatment process by reducing the sludge volume and stabilizing it. 1J.frrfl:i ta � I I i Ar I Li I I I I I II I I One operator at the 'main control panel can run the entire process system for the 'South Complex and anaerobic digesters. Complex pressure switches and level transmitters are part of the analog system which controls the primary effluent pumps. Left The cryogenic oxygen plant control panel is one of three in the Secondary Complex control room. Inset This console control panel contains the instrumentation and controls for the aeration basin treatment process. The keyboard in the center provides direct access to the main computer. Dual Computers Instrumentation and control system lowers costs. A highly successful dual com- puter system controls more of the routine work than either electronic local controls or human hands at the Central Treatment Plant. Digital feedback control splits the effluent flow between the North and South Complexes, returns sludge flow to the aeration basins, monitors pre- set water quality characteristics, and even turns valves and pumps on and off in sequence. The Metro plant is monitored and controlled by one of the first successful wastewater closed -loop computer control systems in the United States. The system uses 'such advanced concepts as remote multiplexing and distributed proc- essing to perform all process 'functions at the plant. Return acti- vated sludge flow is proportioned in relation to raw flow and the anaerobic digesters used to reduce 'sludge volume and stabilize it are automatically charged on a mass basis, under direct computer con- 'trol. The system also monitors methane gas production and eval- uates digester performance by measuring the methane gas con- tent in each digester. Pump wear is distributed and controlled and motor maintenance is automatically scheduled, based on how long the motors have been running. Software also monitors plant power consumption at each major primary distribution center and the plant is already set up for the addition of electric demand control in the future. Because it is a dual computer system, there is always one backup computer available to run the plant from the main computer center. One operator at the main control panel can control and monitor data from three other panels which also control the primary and secondary treatment systems and the digesters sepa- rately. Cathode ray tube units in all three centers allow operations personnel to analyze current plant data and take action as needed. Even if the operators should need to bypass the central computer, or if there should be a complete computer failure, they can still control the process and facilities from the three local control centers through analog control panels. Major operation status changes, such as conversions to adjust treat- ment from summer to normal winter flow quantities, require field intervention by the operators to add or remove major process elements from the flow stream. Beyond these seasonal shifts, the South Complex can be run from the main plant control room through the central computer system.

Solids Reuse The heart of an agricultural reuse program. The organic nutrients in sludge make it a natural for enriching soil used to produce grass and forage crops. That's the idea behind the next stage of Metro's construction and treatment program. An existing disposal system already applies sludge to land, but at a site which is reaching its capacity. Vacuum filtration and flash drying were methods used to dewater solids in the past, but they are now becom- ing too energy intensive. Metro, looking for a more economical reuse system, again turned to CH2M HILL. Because the primary and waste - activated sludges are stabilized in anaerobic digesters, they make a product which is safe for use as a soil conditioner and fertilizer on cropland. Liquid digested sludge from the Central Wastewater Treat- ment Plant will be pumped through a 25 -mile pipeline to a special drying and distribution center. At the 2,000 -acre site, the sludge will be dried on 600 acres of drying beds and stockpiled for reuse. Although dried sludge is often more marketable, liquid sludge will also be available. Who will use the sludge? Mining com- panies, to return mined areas to natural con- ditions; city and county agencies, to landscape open spaces; and farmers, to save costs by using a local product which already contains organic nutrients. In the long run, this agricultural reuse program will return organic solids to natural sites, recycling a valuable resource. Savings of en- ergy and other resources from this system will cut Metro's operating costs by half and save $1 million in natural gas energy, which would be used if Metro had to return to drying sludge by the flash drying process used in the 1960s. Sludge has been demonstrated to have a value for agricultural reuse, as conlirmed by testing in both wheat and corn lest plots.

Linton, Executive Director of the Association of Metro- politan Sewerage Agencies, Washington D.C., gave the dedication address at the Central Treatment Plant. The dedication on 22 May 1977 marked the successful completion of the $37 million expansion project for the Central Treatment Plant begun in 1974. Primary and secondary treatment facilities are.now able to treat a wastewater flow rate of 170 million gallons per day. Anaerobic digesters reduce the overall sludge volume which must be handled and stabilize the sludge to produce a safe agricultural soil conditioner and fertilizer. A portion of the expansion project was funded by a $25 million bond issue by the voters of the Metropolitan Denver Sewage Disposal District No. 1, with additional matching funds from the State of Colorado and the United States Environmental Protection Agency.

I water quality in the Tualatin River Basin. The Tualatin River drains most of Washington County, Oregon, flowing 'through both rural and urban areas. Once a clean and beautiful river, the Tualatin had by the early 1960s become 'heavily polluted, overloaded with in- adequately treated wastes being dis- charged into its tributaries by more than two dozen treatment plants. Today, 'thanks to a major regional water quality improvement program, that pollution has been nearly eliminated. In the face of rapid growth and intense pressure for ur- 'banization, the people of Washington County have successfully carried out a program to clean up the Tualatin River, 'while at the same time allowing planned growth to occur. Unified Sewerage Agency serves regional needs. The task of cleaning up the Tualatin River required that political and jurisdic- tional boundaries be set aside in order to provide a regional solution to a truly re- 'gional problem. In 1964, Washington County officials began discussing alter- native solutions to the growing waste disposal problem. At that time, 25 small 'treatment plants, under the jurisdictions of 16 separate sanitary districts, were discharging partially treated wastes into the already heavily polluted tributaries of the Tualatin River. A Water and Sewer- age Master Plan for the area recom- mended consolidation of these districts into a regional agency, and operation of 'three major treatment facilities on the river itself to replace those located on its tributaries. In 1970, Washington County 'residents, by a 2 to 1 vote, created the Unified Sewerage Agency (USA) as the agency responsible for implementing the Sewerage Master Plan. USA is a regional agency —its jurisdic tion comprises approximately 95 square miles, about 13 percent of Washington 'County, Oregon, and small portions of the City of Portland, Multnomah County, and Clackamas County that lie within the Tualatin River Basin. USA serves 80 per- cent of Washington County's population, a population that is projected to more than double in the next 20 years as hous- ing and industry augment traditional ag- ricultural uses. To finance the 10 -year, $80 -million construction program outlined by the master plan, USA obtained federal and state grants of up to 75 percent of project costs. General obligation bonds were used to fund the local share of the cost. The Rock Creek Advanced Wastewater Treatment Facility is the third of three treatment facilities to be brought on line under this program. The Durham Facility began operation in 1976, and the Forest Grove Facility, one of the older plants, was updated and expanded. To connect existing sewerage collection systems to the new facilities, nearly 40 miles of in- terceptor sewers have been built. Com- pletion of the Rock Creek Facility signals the end of the major construction phase. V[,. The facility For the people of Washington County, the completion of the Rock Creek Facil- ity means relief from the severe pollution problems that occurred in the Tualatin River and its tributaries. During the winter months, the plant will remove over 90 percent of the wastes from the water before discharging it to the river. Beginning in May (or earlier if the river drops below a pre -determined level) until November, 95 to 99 percent of the pollutants will be removed. The Tualatin River can safely assimilate the remaining amounts. The Rock Creek Facility has a design capacity of 660 liters per second (15 million gallons per day) and a peak Raw sewage pump station skylights ( lxpwn prndur rirm rape skid capacity of 1,980 liters per second (45 million gallons per day). As projected population growth occurs, the plant can be expanded to serve the future needs of the region. Design features reduce operating costs and conserve energy. Many features have been incorporated into the Rock Creek Facility to reduce operating costs and conserve energy. For example, as sludge (the solid part of wastewater) is processed, it releases methane gas. This methane is rechan- neled and used as an energy source for the heating system and to generate elec- tricity for plant use. One -fifth of plant energy requirements can be supplied by this feature alone. Generous use of skylights in many buildings has reduced the need for artificial lighting. The facili- ty's computer continuously monitors equipment running time and helps to schedule maintenance work and needed repairs. Equipment and control panels are in metric units in anticipation of the national conversion to the metric system. Pipes within the facility are color -coded and labeled, enabling operators to tell at a glance what substance each pipe transports (such as digested sludge, com- pressed air, or backwash). The labels can easily be removed, eliminating the need to reletter the pipes each time they are painted. Low -maintenance ground cov- ers have been used to landscape the plant site. USA is exploring new ways of turning both effluent and sludge into important resources. Treated effluent from the Rock Creek Facility will be used by a local irri- gation district and a local nursery during the summer. This will allow the water to stay in the Tualatin Basin at a time when it is critically needed. To complete the cycle, USA, in conjunction with Oregon State University, is researching the appli- cation of sludge to nearby agricultural lands. Because it contains both organic matter and nutrients, and as costs for commercial fertilizers rise, the use of sludge as a supplementary fertilizer or soil conditioner is growing in potential. In addition to making efficient use of re- coverable resources, these programs will allow USA to recoup a portion of its operating costs. Digesters Administration building Removable process flow label 3 • - 7 ijTh, t S. - 1 1' •1 _ w r� mot---• d { Management system saves time ... saves money. By late 1974, it was clear that use of a traditional project delivery system to construct the Rock Creek Facility would not meet the needs of the rapidly grow- ing service area. USA asked its consul- tant, CH2M HILL, to identify an approach that would save time. In its study report, the consultant estimated that use of a construction management system (CMS) approach could complete the facility nine months earlier than a traditional de- livery system and save USA $1.5 million. Based on the findings of that report, USA proceeded to obtain Environmental Pro- tection Agency funding using a CMS ap- proach. Continuous design -construct phasing saves time. The construction management system requires a strong commitment from each member of the project team: the owner, regulatory agencies, designer, construc- tion manager, and contractor must fully communicate and effectively coordinate their work to keep pace with the acceler- ated schedule. By assigning full-time staff to the CMS effort and by actively par- ticipating in the project from the outset, USA was able to exercise maximum con- trol over the completion time, cost, and quality of the project. Functioning as an extension of USA staff, CH2M HILL con- struction managers provided intensified management services and helped obtain initial and ongoing approval from state and federal agencies. In turn, these agen- cies cooperated by reducing review times, cutting traditional delays even further. Cost savings resulted from the early start on construction and shorter overall construction time. Costs were further reduced because bidding the pro- ject in many small packages attracted more bidders, sharpened competition, and reduced the traditional general con- tractor's markup on subcontractor bids and equipment. As a result, the project was completed well within time and cost objectives set by USA. Coordinated project team effort saves money. The Rock Creek Facility is the first EPA -funded wastewater treatment facility to use a construction management sys- tem approach. The project's success has led EPA to encourage other states and owners to use CMS as a means of stretch- ing water pollution control funds. In- novative leadership of the Unified Sewerage Agency and outstanding cooperation by state and federal agen- cies has made the Rock Creek Facility a project in which everyone can take pride.
