Attachment A
Fayetteville Sewer System Study
Scope of Work
June 14, 1995
General
The purpose and goal of the Sewer System Study is to identify and evaluate alternatives for
needed improvements and expansion of Fayetteville's wastewater collection and treatment
facilities. The overall project goal includes recommendations for the City in meeting State and
Environmental Protection Agency (EPA) regulations pertaining to sewer system overflows, as
well as applicable water and air pollution requirements.
The project initially includes the facility planning and this Scope of Work identifies the
associated work tasks. Additional tasks will be required to complete the project; however,
their particular need and scope of work cannot be developed at this time. Some of these
additional tasks might include such items as: specific stream sampling/modeling; Revolving
Loan Fund (RLF) program requirements including the application and rate/financing analysis;
additional assistance in the area of public information/involvement; National Pollutant
Discharge Elimination System (NPDES) regulatory assistance; sampling and analytical testing;
environmental impact studies; and CORPS 404 permit assistance. The City of Fayetteville may
authorize some of these tasks to be performed when the need is identified and the work scope
can be defined. The Scope of Work for the design and construction phases cannot be
specifically defined until the completion of the Sewer System Study.

flow and loading data for wastewater treatment plant (WWTP), previous and
projected industrial growth, descriptions of major industries, and wastewater
flow and pollutant concentration data for industries.
B. Population and employment estimates and forecasts by the City's Planning
Division for the year 2020 will be the basis for the planning effort and
projection of future flows and loads. Water -use projections being developed on
a separate project will also be made available by the OWNER and correlated
with the development of wastewater flow projections along with the planned
population growth.
C. Based on historic data and information developed in Task No. 7, develop
average per capita flows and loads to the WWTP. This data will then be used
to project average future flows and Toads. Segregate the projected flows and
loads between the White and Illinois watershed for the ultimate planning
conditions. Projected basin flows will be based on a breakdown of population
and industrial growth projections by subbasin developed from existing
transportation zone population and employment information provided by the
OWNER.
C. Based on Iustonc data, develop flow and Toad peaking factors and recommend
peaking factors to use as the basis for design. Use the recommended peaking
factors to estimate peak -hour flows (which will be used for sizing of hydraulic
elements) and the peak -month, peak -week, and peak -day loads to the WWTP
(which will be used to evaluate and size treatment facilities).
D. Document the results of this task in a draft technical memorandum (TM) and
submit to OWNER for review.
Task 5 -Treatment Plant/Sludge Land Application Facility Evaluation

recommendations by OMI to meet 503 sludge stabilization requirements
through operational changes, as well as odor mitigation measures.
C Summarize existing information including previous studies relative to odor
abatement to serve as a basis for development of a conceptual design for the
anticipated digester improvements.
D. Conduct an onsite evaluation including a 3 -day workshop to assess and
evaluate available alternatives and development of a recommended approach.
This effort will be conducted outside schedule constraints of the overall Sewer
System Study. This approach will provide the City with the opportunity to
expedite identification and implementation of the recommended sludge
treatment and associated odor abatement facilities at the plant.
Assess potential odor sources in addition to the aerobic digestion process
within the plant and collection system that may contribute to complaints.
Identify potential mitigation measures to reduce potential odor sources.
F. Identify and define areas where there have been odor complaints that may be
related to collection system facilities. Evaluate sources of odors and
recommend structural and/or operational modifications to mitigate odor
sources.
TUL1602.D1CC123.doc -A-5
Document the evaluation and recommendations in a Conceptual Design Report
resulting from the workshop. This report would include budgetary cost
estimates and considerations of a phased implementation approach. Upon
review and acceptance by the City, this Conceptual Design Report would be
used to develop a design scope of work for consideration by the City.
Task 7- Collection System
A. Meet with OWNER's staff to define objectives and constraints associated with
the evaluation of the City's sewage collection system. Confirm existing
problem areas and establish priorities for evaluation.
Analyze flow data from major lift stations including Porter Road, Old Wire
Road, Gregg Street, Popular Street, and Lift Station No. 12 to determine
current flow rates. Compare to flow data obtained during previous studies and
develop dry- and wet -weather hydrographs for each subdrainage basin. Flow
data from major lift stations are to be provided by the City.
Using the above data, determine existing base flow loadings on a per capita
and employee or per acreage basis based on population and employment
information developed in Task No. 4.
D. Review water usage records (obtained in Task No. 4) and industrial
pretreatment records for large industrial users. Interview personnel at large
industries to determine future plant expansion plans.
Using population and employment projections and water usage projections
provided by the City in Subtask No. 4, project future wastewater flow rates by
subbasins
Perform temporary flow monitoring to determine wastewater flow rates for
Greenland. Wastewater flow rates from Elkins is currently being determined as
part of the Illinois River Phase II Sewer Project. Flow data for the City of
Farmington will be provided by the OWNER.
G. Develop a City-wide collection system hydraulic model (SWMM) including all
sewers 10 inches in diameter and larger from information contained in the
White and Illinois River Watershed Sewer System Studies. The model
development assumes that the OWNER will provide the White River model
database in electronic format that is suitable for use in the SWMM model.
Provide model used in this study to the OWNER and train OWNER's staff in
its use
Using existing data and the additional flow data obtained in Subtask 7.F above,
calibrate the system model and assess the hydraulic conditions in the major

•
collection system lines, lift stations, and force mains. It is anticipated that the
model will be calibrated to existing dry -weather conditions and to one selected
storm condition.
H. Assess the City's current approach and ongoing sewer rehabilitation efforts to
eliminate bypasses and overflows and identify appropriate assumptions for
future inflow/infiltration (I/I) reduction. This effort will focus on the following:
• Reliability of Existing Flow Data
• Rehabilitation Impacts on the Plants
• Effectiveness of the I/1, Sewer System Evaluation Survey, and
Rehabilitation Efforts To -Date
• Direction and Focus of Future Rehabilitation Efforts
This assessment will be performed based upon existing information including
previous reports and hydraulic modeling results. A 4 -day value engineering
workshop approach will be used to assess existing information and to make
recommendations for future I/1 efforts. A summary (provided by RIN) of the
current and ongoing rehabilitation efforts will be the basis of evaluation during
the workshop.
The first priority will be in the western area of Fayetteville and a small area in
the southeast portion of the collection system. The goal will be to identify
short-term solutions and recommendations in these areas for needed remedies
independent of the longer-term recommendations. This will be done and
reviewed with the City on an accelerated basis while the other Sewer System
Study tasks are being accomplished.
Utilizing flows projected and provided by OWNER under Task 4 previously,
determine the existing collection system's capability to function under future
flow conditions. Through model simulation of 10 -inch pipes and larger in both
the White and Illinois watersheds, determine additional system improvements
needed from major collectors to interceptors and any lift station improvements
that may be required. These improvements will be ranked according to priority
based on 1, 5, 10, 15 years, and ultimate needs. These improvements will be
formulated based on the needs of each subbasin when it reaches ultimate
development.
K. Provide maintenance management system software and a 586 pentium
computer with a monitor that is capable of utilizing the City's existing

B Receive comments from the OWNER and incorporate them into a final Sewer
System Study. Because all information presented in the draft report will have
previously been submitted to and reviewed by the OWNER (in the form of TM
or meeting notes), it is anticipated that only minor review comments will be
received.
Submit 20 copies of the Report to the OWNER, along with 15 copies of a
bound Executive Summary for use by City Council.
Task 14 -Sewer Overflow Basin Conceptual Design
A. The purpose of the conceptual design will be to identify optional approaches to
eliminating or storing potential sewer system overflows during wet weather
events until the flows can be reintroduced into the collection system and

conveyed to the WWTP As a result of this activity, needed facilities will be
identified so that final design can proceed
Through discussion with the City and existing overflow reporting records,
establish locations along the 15th Street interceptors in addition to the
Salvation Army and Happy Hollow Lift Station locations where overflows
have historically occurred.
Utilize wet weather flow projections provided by the City (from ongoing RJN
project) to identify the cause and potential solutions for the overflow. Two
separate and independent overflow conditions are thought to exist. They are as
follows:
• Evaluation of the overflow near the Salvation Army will include
possible: 1) elimination of potential interceptor restrictions
down gradient from the Salvation Army; 2) providing additional
interceptor capacity, and 3) basin to contain and store projected
overflows until they can be reintroduced into the collection
system.
•
The overflow at the Happy Hollow Lift Station is a direct result
of having to shut the lift station down to prevent overloading
the WWTP's headworks pumping capacity. Resolution of this
condition will include. 1) providing storage basin capacity at or
near the lift station or at the WWTP and/or along the gravity
force main route to the plant; and 2) evaluation of the lift
station's capacity to handle the project flows.
Evaluate existing excess flow equalization storage facilities at the WWTP and
integrate this capacity into potential solutions.
D. Develop overall system flow capacity analysis relative to the overflow
conditions near the 15th Street interceptors.
E Utilize the hydraulic model results and data input provided by RJN on other
City ongoing project work to evaluate several different scenarios to resolve the
overflow situation
F. The results of the analysis and evaluation will be summarized in a TM including
a recommended approach to resolving the overflow condition This will be
presented to the City staff in a workshop and a decision reached of the desired
approach. Applicable review comments will be incorporated along with
defining the specific design criteria for the proposed facilities. The final
outcome will be documented by finalizing the TM. This TM will be used as the

basis for facility design and can also be used as a submittal to reviewing
agencies if appropriate.
Task IS Project Management/Administration
A. At the beginning of the project, the ENGINEER's project manager will
prepare project instructions for use by the project team during the course of
the project. The instructions will outline procedures, summarize project goals
and objectives, present schedule and budget guidelines, present quality
control/quality assurance (QA/QC) procedures, and other information that is
pertinent to the successful completion of the project.
The ENGINEER will coordinate and manage execution of the overall project
tasks throughout the project among own staff and other team members
participating as subconsultants.
C. The ENGINEER's project manager will monitor the status of the project to
such that the project is completed within the agreed upon budget and schedule
constraints
The ENGINEER's project manager will discuss project status with the
OWNER designated representative on a monthly basis.
