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 snowpack 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 TUD’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

TUD’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.

Throwback Thursday!

This historic photo of the Sonora Water Treatment Plant in the early 1900s is a reminder of the people and infrastructure that helped build the foundation of the water system that we rely on today. While water treatment technology has evolved, the goal remains the same: provide safe, reliable drinking water to the community!

Have you ever heard the term "acre-foot"?
It's one of the most common ways water agencies measure water! An acre-foot is the amount of water needed to cover one acre of land with one foot of water (about the size of a football field).
At TUD, understanding water measurements helps our community appreciate the value of every drop and the importance of managing our water resources wisely.
