Iron And Manganese Treatment At Well 31

Solicitation PUD 2026-18 is a project for the City of Clovis, California, focused on the installation of an iron and manganese filtration system at Well 31. The scope of work encompasses comprehensive civil, electrical, and mechanical installations, including the procurement and installation of filter pressure vessels, manganese dioxide filter media, hydraulically operated backwash valves, and support skids. Key infrastructure requirements include the construction of filter vessel pads, site piping, and a connection to the existing sanitary sewer along Leonard Avenue. The contractor is responsible for all labor and materials, including excavation, utility location, electrical instrumentation and controls, and the final leak testing and disinfection of the system. All materials in contact with potable water must be certified to ANSI/NSF Standard 61, and surface improvements must adhere to 2010 ADA Standards and 2025 California Building Code requirements. The contract is awarded based on the comparison of base bids for the entire project, with alternate items awarded at the city's discretion. Bidders must provide a bid security of at least 10% of the bid amount and, upon award, furnish performance and labor and materials bonds each equal to 100% of the contract price. The project includes a two-year guarantee and requires the contractor to comply with prevailing wage laws. Bids must be submitted in sealed envelopes to the City Clerk by November 10, 2026. Required submission documents include a non-collusion declaration, worker's compensation certificates, and references for three similar filtration projects completed within the last five years. The city will inspect all work phases on concrete facilities, and final progress payments are contingent upon the completion of all contractual obligations.
