Conservation

Following several months of storms bringing much-needed snow and rain to California, conditions have dramatically changed for many parts of the State. In response, Governor Newsom has rolled back some drought emergency provisions that are no longer needed while maintaining other measures that support regions and communities still facing water supply challenges.

Effective Sunday, May 14, 2023, Golden State Water Company modified outdoor watering restrictions to allow for watering up to three days per week. Given that water conditions will continue to evolve, customers are encouraged to use water wisely and only use what is needed.

Golden State Water is recommending customers limit outdoor irrigation between the hours of 7 PM and 8 AM per the following schedule:

Addresses Ending In:	Watering Days:
Even Numbers (0, 2, 4, 6, 8)	Sunday, Wednesday, Friday
Odd Numbers (1, 3, 5, 7, 9)	Tuesday, Thursday, Saturday

Rates

As a regulated utility, Golden State Water’s rates are determined by the California Public Utilities Commission (CPUC) through a General Rate Case (GRC) to ensure customers receive a fair rate for reliable, quality water service. New rates allow for investments to avoid the costly and sometimes dangerous effects of deferring maintenance or delaying the replacement of aging infrastructure.

2023 GRC (2025 Rates)

As required by the CPUC every three years, in August of 2023, Golden State Water Company filed its 2023 General Rate Case (GRC) with the California Public Utilities Commission. This rate plan proposes local infrastructure investments and water rates for the years 2025, 2026 and 2027. Any adjustments to current rates will not go into effect until January 2025, at the earliest. Click here to learn more.
