The Tenaya Lodge Wastewater Treatment Facility Project was located on Highway 41 in Mariposa County, just south of the Highway 41 gate to Yosemite National Park. This project consisted of the construction of a new wastewater treatment facility to replace an aging plant used by the Tenaya Lodge. This project included clearing of an existing forested area to make room for the new site, imported borrow, installation of 200,000 gallons of underground storage, and construction of a 4,550 SF steel building to house a pre-engineered Membrane Bioreactor System. This project also included a 350kW generator, water main, gravity sewer mains, gas main, lift stations, and modifications to the existing leach fields.
