Overview


Summary

West County Wastewater District (WCW) is soliciting bids from qualified contractors to provide construction services for the Secondary Sedimentation Basins 1 and 2 Short-Term Improvements Project at the Water Quality & Resource Recovery Plant (WQRRP). WCW identified the need to rehabilitate and upgrade all four secondary sedimentation basins at the WQRRP to maintain reliable operation and treatment performance and retained Black & Veatch to provide engineering design services for the improvements.

The work under this contract is limited to Secondary Sedimentation Basins (SSB) 1 and 2 and generally includes demolition, concrete repairs, coatings, mechanical improvements, site restoration, and all other work necessary to complete the improvements in accordance with the Contract Documents. West County Wastewater District will directly procure and furnish the replacement collector chains and flights for SSB-01 and SSB-02; however, the Contractor shall be fully responsible for receiving, handling, storing, protecting, coordinating, and installing the owner-furnished equipment as part of the Work.

Contractors shall provide all labor, materials, equipment, supervision, and incidentals necessary to complete the project and place the rehabilitated facilities into successful operation in accordance with the Plans and Specifications.



Background

West County Wastewater (WCW) provides wastewater collection and treatment services to approximately 93,000 residents. WCW was created December 19, 1921, pursuant to authority of the State of California. Today, WCW operates as a political subdivision of the State of California as an independent special district. WCW's current political boundaries are comprised of the City of San Pablo, a portion of the City of Richmond, a portion of the City of Pinole and some unincorporated areas within western Contra Costa County.

WCW's system includes 249 miles of gravity sewer pipelines, 17 lift stations, 6 miles of pressurized force mains, and a water quality resource recovery plant with an NDPES permitted capacity of 12.5 million gallons per day (MGD).
