Y--Sources Sought YOSE Water & Sewer piping

The project involves a comprehensive upgrade and extension of the water and sewer systems near the Big Oak Flat Entrance and Hodgdon Meadow Campground in Yosemite National Park. It includes replacing the existing water source, supply, and distribution infrastructure with approximately 1,200 linear feet of raw water line, 7,900 linear feet of water supply line, and 8,100 linear feet of water distribution piping, along with related appurtenances servicing the Big Oak Flat Welcome Center, Hodgdon Meadow Campground, and staff housing. Key components also encompass demolition of the current 100,000-gallon welded steel water storage tank and construction of a larger 210,000-gallon tank with an access road, installation of a new water source well and pump, a new water treatment and control building, nearly 3,200 linear feet of electrical distribution, and 3,800 linear feet of communications lines. The existing asbestos cement water main will be abandoned in place. Additionally, the contract addresses improvements to the wastewater system by connecting the Big Oak Flat sanitary sewer to the Hodgdon Meadow Campground sewage system. This includes constructing approximately 3,500 linear feet of 6-inch sanitary sewer line, 20 sewer manholes, and three service laterals to enhance sewage management capabilities. The solicitation for this project falls under NAICS code 237110 and is issued by the Department of the Interior’s DSC Contracting Services Division. The deadline for responses is June 1, 2026, and key coordination is through the designated point of contact at the National Park Service. The overall effort aims to modernize essential water and sewer infrastructure to improve reliability and service in this heavily visited park area.
