San Gabriel

Overview

Golden State Water is proud to be San Gabriel Valley’s water provider since 1929, serving high-quality, reliable water to approximately 12,300 customers in portions of Arcadia, El Monte, Irwindale, Monrovia, Monterey Park, Rosemead, San Gabriel and Temple City.

Two water systems serve the area. Water delivered to customers in the South Arcadia System is groundwater pumped from the Main San Gabriel Basin. The basin underlies the San Gabriel Valley from Alhambra to San Dimas. Water delivered to customers in the South San Gabriel System is also pumped from the Main San Gabriel Basin and the water system has the ability to supplement supplies with imported water from the Colorado River Aqueduct and the State Water Project (imported and distributed by the Metropolitan Water District of Southern California).

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.

2020 GRC (2023 Rates)

Effective July 31st, 2023, the California Public Utilities Commission approved the 2020 GRC which includes new rates to ensure the safety and dependability of your local water system. The new rates allow for investments to avoid the costly and sometimes dangerous effects of deferring maintenance or delaying the replacement of aging infrastructure.
