Tuolumne Utilities District

Tuolumne Utilities District Tuolumne Utilities District was created in July 1992, following approval by Tuolumne County voters to consolidate two existing water agencies.

TUD Mission:
Provide Responsible Water and Wastewater Services for our Customers with Great Customer Service in a Socially, Financially and Environmentally Responsible Manner at a fair value. TUD oversees water delivery and water treatment for most Tuolumne County communities and operates the county's largest wastewater treatment system. WATER

Tuolumne Utilities District relies on the Sierra snow

pack for its water supply, fed to reservoirs by the South Fork Stanislaus River. The most important watershed for the District is the area above Pinecrest Lake. This watershed flow comes from snowpack that melts and fills the reservoir for water supply throughout the year. Pinecrest Lake and Lyons Reservoir are part of two hydro-electric power generation facilities owned, maintained and operated by Pacific Gas and Electric Company (PG&E). In an agreement with PG&E, TUD receives its water supply from Lyons Reservoir through the 15.7 mile Main Canal. 95% of the water used by TUD customers comes from this stored water supply and is then fed through TUDโ€™s ditch system. TUD has 14 water treatment plants in various locations throughout the County. Most of these treatment plants were acquired when previous water agency providers could not meet State drinking water requirements. The District provides water to about 14,000 water connections or a population of 35,000, 24 hours a day, 365 days per year. SEWER

TUDโ€™s wastewater system serves over 12,030 single family equivalent sewer connections and treats 1.8 million gallons of sewage daily at the Regional Wastewater Treatment Plant located in Sonora.

๐Ÿ TUD's four-legged landscaping team chewed through their to-do list!

These hardworking goats are helping TUD manage vegetation the natural way by clearing grasses, weeds, and brush in areas that can be difficult to reach with equipment.

Not only are goats an eco-friendly alternative to traditional vegetation management, they also help reduce wildfire fuels without the use of spark-producing equipment, fuel, or herbicides. In fire-prone areas, that means fewer ignition risks while still getting the job done.

Check out these before-and-after photos and see why they're the GOATs of vegetation management! ๐ŸŒฟ๐Ÿ”ฅ๐Ÿ

Water is at the heart of every California community, and planning for the future starts today.
Recognizing the importance of long-term water reliability, the Tuolumne Utilities District Board of Directors recently adopted a resolution supporting Vision for Our Water Future, a statewide effort led by the Association of California Water Agencies (ACWA).
This initiative brings together water agencies from across California to advocate for policies that strengthen water supplies, invest in critical infrastructure, protect the environment, and build more resilient communities.
For TUD, joining this vision reflects our commitment to providing reliable water service while helping shape a sustainable water future for the communities we serve. As California faces ongoing challenges from drought, wildfire, aging infrastructure, and a changing climate, collaboration and investment are more important than ever.
TUD is proud to stand with water leaders throughout the state in supporting a shared vision that prioritizes water for people, communities, the economy, and the environment.
