West Hill Booster Pump Station
City of Kent Request for Qualifications (RFQ)
West Hill Booster Pump Station
Submissions Due 8:00 a.m. Monday, October 9, 2023
The City of Kent is requesting a statement of qualifications for professional consultant services for the design of a City of Kent water booster pump station (BPS). The BPS is needed to alleviate the three aging pump stations currently filling the newly constructed 5MG West Hill Reservoir. This new pump station will be connected to the West Hill via a new transmission main and will provide redundancy to the water supply system on the West Hill.
The need for a new BPS was identified in the City’s 2019 Waster System Plan (WSP) update. Attached is the project description from the WP and a vicinity map. The City has identified three possible sites for the pump station and identified a preferred site. Consultant will be required to obtain all necessary permits, City will pay permitting fees. The total project cost is estimated at $2.8 million in 2019 dollars.
The future BPS will be located on Veterans Drive near the Green River and will pump water from the City’s 240 foot pressure zone to the 587 foot pressure zone of the West Hill Reservoir. The WSP update also includes a new 1.2 mile, 16” diameter water main which will bring water from the proposed booster pump station up Veterans Drive and south on Military Rd to S 240th St where the new waterline will connect to the existing water system to fill the reservoir. The City is still evaluating whether the transmission main design will be included as part of this consultant contract or if this work will be designed in house by the City. The proposed transmission main will cross WSDOT right of way (SR 516) and may need to cross King County right of way south of SR 516. The total transmission main cost is estimated at $6 million in 2019 dollars.
The engineering services will generally consist of designing a complete pump station in accordance with City and State requirements. Included are site determination (City to verify), pump station, piping, electrical service, controls, telemetry, generator, fuel tank, permitting and other related features need for a fully functioning BPS. The City is still evaluating whether the civil site work outside of the building will be included in the consultant’s scope of work or if the civil site work will be designed in house by City staff. The City will be responsible for the site survey and all bid advertising. The consultant will provide technical specification in Construction Specifications Institute (CSI) format for inclusion into the City’s bid package. A Department of Health permit has been acquired for the West Hill Reservoir which includes the proposed BPS and transmission main, however, it may need to be updated as a result of the project.
Redundant pumps, backup power, and SCADA controls will need to be incorporated into design. Preliminary modeling indicates a pump station with 3 pumps and a 2,000 GPM firm capacity of the pump station. However, consultant input and hydraulic calculations will be required, City to verify final sizing. Exact number, type, configuration and specifications will be determined during design, and all pumps will have VFD pump control and SCADA.
