Tuolumne Utilities District continues to undertake capital improvements in support of upgrading the District’s drinking water infrastructure and sewer infrastructure. The District's current 5-year Capital Improvement Plan (CIP) invests nearly $40 million in critical infrastructure improvement projects.


At the April 6, 2023 Board meeting, the Tuolumne Utilities District (TUD) Board of Directors authorized staff to proceed with the Proposition 218 (Prop. 218) rate increase process which includes providing notices to customers regarding potential rate increases. The proposed rates have been calculated using a cost-of-service study which was conducted to ensure that TUD has adequate revenue to continue to maintain safe and reliable water and wastewater service to its customers. The study concluded that current rates are insufficient to provide necessary funds to pay the costs of operations, maintenance, administration, debt service and capital improvement over the next five years.

In order to continue to provide safe, reliable and quality water and wastewater services, TUD is proposing a five-year rate increase to all customers. If approved, the rates would take effect on August 1, 2023, and each July 1st thereafter for each of the remaining years through 2027.  As required by state law, TUD has compiled a Prop. 218 Notice which shall be mailed to all water and wastewater customers. The notice can also be found below. Additionally, the District will hold a public hearing to consider adopting the proposed rates:

DATE AND TIME OF PUBLIC HEARING: Wednesday, June 14, 2023, at 9:00 a.m.
