Tuolumne Utilities District (TUD) is a water and wastewater utility serving nearly 44,000 residents in northern California’s Tuolumne County. A scenic drive along Highway 108, heading east from the Stanislaus County line to Pinecrest Lake and Dodge Ridge, takes you through the heart of TUD‘s service area and gives you an overview of the extraordinary geographic diversity of the region.

Water has been and continues to be an undeniable force in shaping the economic, ecological and cultural face of our county. From the earliest days of habitation by American Indians to the discovery of gold in Columbia that sparked the California gold rush, from clusters of black oak and manzanita to pine forests in the Sierra Nevada range, from abundant vineyards and orchards to growing population centers—water is the essential link.

TUD customer needs are as broad ranging as the area’s diversity. We provide drinking water for homes, schools and businesses and recycled water from our wastewater treatment plant to irrigate prime agricultural lands near Jamestown. In all we do, we strive to meet or exceed federal and state standards for water and wastewater quality, environmental protection and wildlife habitat.
