Sierra Pines Regional Water Treatment Facility Project

Sierra Pines WTF

TUD is proposing to construct and operate the proposed Project on 46-acres near Twain Harte, California in unincorporated Tuolumne County. The first phase of the proposed Project (the subject of analysis in the IS/MND) involves construction and operation of a water treatment facility with an initial operational capacity of 3 million gallons per day (mgd). The proposed Project water treatment facilities include a new 30-acre-foot-capacity raw water reservoir, a raw water pump station, filter building, sludge lagoons associated appurtenances and electrical structures, water conveyance pipelines, a stormwater detention basin, as well as new recreational trails and amenities. New water transmission pipelines would be installed offsite (within the franchise position of roadways and other public rights of way) to convey treated water to existing TUD facilities.
