YOSE Rehabilitate the Sewer System at the Mather Ranger Station and Housing Area to Prevent Failures

The Department of the Interior is planning a project to rehabilitate the sewer system at the Mather Ranger Station and Housing Area to prevent future failures. This initiative involves replacing two existing sewer systems at the Hetch Hetchy Entrance Station and consolidating their flow into a single, unified system. The new infrastructure will collect wastewater from Building 2000 and the tent cabin area, utilizing gravity to convey the waste to new septic and dosing tanks. From there, liquid effluent will be pumped to a newly established leach field located east of the tent cabins. The technical scope of the project includes the installation of approximately 100 linear feet of 4-inch HDPE collection lines and 500 linear feet of 6-inch piping. This contract is categorized as a total small business set-aside under FAR 19.5, specifically targeting small businesses within the NAICS code 237110. The project is currently listed as a forecast, with the Department of the Interior serving as the primary agency responsible for the execution of these infrastructure upgrades.
