prevents their early assignment to the aforementioned work; and whereas the "ENGINEER'S" staff
' is adequate and well qualified and it has been determined that its current work load will permit
completion of the plans for the project on schedule;
' Now, therefore, it is considered to be in the best public interest for the "OWNER" to obtain
assistance of the "ENGINEER'S" organization in connection with said engineering services. In
consideration of the faithful performance of each party of the mutual covenants and agreements set
1 forth hereinafter, it is mutually agreed as follows:
SECTION I - EMPLOYMENT OF ENGINEER
' The "OWNER" agrees to employ the "ENGINEER" to perform, and the "ENGINEER" agrees to
perform, professional engineering services in connection with the project set forth in the Sections
to follow; and the "OWNER" agrees to pay and the "ENGINEER" agrees to accept, as specified in
the Sections to follow as full and final compensation for work accomplished in the specified time.
SECTION II -DESCRIPTION OF THE PROJECT
The project generally refers to the planning, design, and construction support services for
improvements to designated wastewater lines and pump stations that will convey wastewater to the
renovated Paul Noland Treatment Plant. The Preliminary Report Phase of the project will be limited
to the lines and pump stations designated by the City in the east (White River) drainage basin. These
improvements are generally located in the southeast half of Fayetteville and are identified in attached
Exhibit A. The City may add additional lines and pump stations from the west drainage basin to this

1 Pump Station No. 21 is located at 1687 Happy Hollow Road. The pump station currently has
submersible centrifugal pumps in a wet -pit configuration but can also utilize gravity flow during
low flow conditions. This pump station serves the industrial park area as well as the remaining
pump stations and sewers in the White River drainage basin area and pumps flow in a 36 -inch
line to the Paul Noland Treatment Plant. This station operates at 480 volts and experiences
overflow problems. Tasks include:
' 1. Obtain existing information from City concerning design drawings, survey data, pump data,
electrical and other utility data, etc.
2. Perform a field inspection of the pump station and appurtenances.
1 3. Examine site and station adequacy to handle predicted flows from data provided by RJN.
4. Using obtained data and projected flows, perform a cost analysis for rehabilitating pump
station versus new station concept. Evaluate the feasibility of providing an equalization
basin.
5. Examine any existing and potential pump station odors by testing of pump station vent gases
and flow into the stations.
1 6. As part of evaluation for an equalization basin, determine wetlands designated areas from
USGS maps, Soil Surveys, Nationals Wetlands maps, and local contact with Corps of

Engineers. Examine any wetlands permitting requirements and cost impacts of construction
needs in delineated wetlands areas.
Sewer Line Examinations
Existing sewer lines will be examined for capacity and existing condition. Information will be
gathered from the City and OMI Industrial Park and West Fork flows will be evaluated.
Proposed improvements will be evaluated based on 20 to 50 -year projections, and
recommendations will be based on economics/constructability. Sewer line capacities will be
based on flow information provided by RJN. Garver will make every effort to avoid duplicating
the efforts of gathering and/or developing information that has already been accomplished by
others.
