Water Station 14 PFAS Treatment

The City of Vancouver, Washington is soliciting sealed bids for the design and construction of a new PFAS (per- and polyfluoroalkyl substances) treatment system at Water Station 14 under Invitation to Bid #26-14. The project scope encompasses the installation of six pressure vessels with granular activated carbon for PFAS removal, an 80,000-gallon backwash/rinse water tank, a restroom and storage building, modifications to existing booster pumps, and associated stormwater, site civil, electrical, and instrumentation/control improvements integrated into the existing water treatment facility. Contractors must possess current Washington Unified Business Identifier (UBI) registration, industrial insurance coverage, compliance with prevailing wage laws, and demonstrated experience completing at least three similar public works projects exceeding $5 million within the last 15 years, with specific expertise in pressure vessel construction for municipal drinking water applications. The contract requires physical completion within 290 working days from the Notice to Proceed, with all work finalized by December 31, 2027, and the geotechnical investigation reveals subsurface conditions requiring a net allowable bearing pressure of 3,000 pounds per square foot for tank foundations on reinforced crushed rock matting. A mandatory pre-bid meeting was held on March 11, 2026, at the project site (6803 NE 78th Street, Vancouver, WA 98665), with questions due March 20, 2026, addenda issued by March 31, 2026, and sealed bids due at 11:00 a.m. Pacific Time on April 7, 2026, at Vancouver City Hall (415 W 6th Street, Vancouver, WA 98660), with submission available through the City's Procurement Portal or in-person delivery.

The project is funded through the Washington State Drinking Water State Revolving Fund (DWSRF) program utilizing federal Environmental Protection Agency funds and City of Vancouver resources, necessitating full compliance with American Iron and Steel (AIS) requirements and Davis-Bacon prevailing wage standards. Contractors must meet disadvantaged business enterprise (DBE) utilization goals of 10 percent for minority-owned businesses and 6 percent for women-owned businesses in construction work, and apprenticeship utilization requirements of a minimum 15 percent for the estimated contract range. A bid deposit equivalent to 5 percent of the total bid amount is required, along with performance and payment bonds equal to the full contract price, and the successful bidder must comply with all applicable federal and state labor standards, equal employment opportunity provisions, and environmental compliance requirements. The project involves integration with existing water treatment operations, requiring carefully coordinated shutdowns limited to one booster pump at a time and a maximum instantaneous wastewater discharge rate of 45 gallons per minute to the Clark Regional Wastewater Department. The Engineer's Estimate for this project is $10,217,000, with the contract award anticipated for a qualified bidder meeting all responsibility criteria and technical requirements outlined in the comprehensive plan set, specifications, and standard contract provisions.
