The West County Wastewater District is soliciting informal bids under solicitation 26-NIIB-052 for the rehabilitation of a 24-inch ACP Class 5000 pipeline on San Pablo Dam Road.

The contract will be awarded to the lowest responsible bidder who meets specific qualification requirements, including holding a valid General A, C-34, or C-42 license and maintaining registration with the Department of Industrial Relations. Bidders must submit a comprehensive package via the OpenGov portal by November 13, 2026, including a bid form, a 5 percent bid security, a statement of qualifications, a non-collusion declaration, and a CARB certification for off-road diesel-fueled fleets.
