Approximately 95% of the water the District distributes originates from the South Fork Stanislaus River and is impounded in Pacific Gas and Electric Company’s (PG&E) Lyons and Pinecrest Reservoirs. PG&E owns and operates a canal and flume system to convey water from Lyons Reservoir to the Phoenix Powerhouse. The District owns and operates a total of 71 miles of ditch, flume, pipe, and tunnel infrastructure that diverts water from the PG&E system at various locations. The majority of TUD customers reside in or near the community of Sonora which is at about elevation 2,000 feet elevation. TUD also serves customers in several communities to the east up to about elevation 6,000 feet elevation past Sierra Village.



The District utilizes approximately 140 miles of sewer pipeline to collect between 400-500 million gallons of sewage per year. The Sonora Regional Wastewater Treatment Plant was constructed in the late 1970’s along with a network of sewer trunk lines to collect sewage from the surrounding areas of Columbia, East Sonora, Mono Village, Mono Vista, Ranchos Poquitos, Soulsbyville, Twain Harte, and Willow Springs. Also in the late 1970’s, a regional reclamation system was constructed that allows for the reuse of the treated sewer effluent for irrigation on pasture lands outside of the community of Jamestown. The overall sewer system directly serves approximately 6,000 residential, commercial and industrial customers.
