San Gabriel

Overview May 29, 2020

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 years of heavy precipitation and snow in California, conditions have dramatically changed for many parts of the State. In response, the state has rolled back drought emergency provisions that are no longer needed while maintaining other measures supporting regions and communities facing water supply challenges.

Effective Sunday, May 14, 2023, Golden State Water Company modified outdoor watering restrictions to allow 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 General Rate Case (2025-27 Rates)

In January of 2025, the California Public Utilities Commission (CPUC) adopted a General Rate Case for Golden State Water Company (Golden State Water) that includes local infrastructure investments and new water rates for 2025, 2026, and 2027. The new rates went into effect February 1, 2025.

These rates reflect Golden State Water’s long-term commitment to providing customers with high-quality water and reliable service by proactively investing in their community’s water supply and distribution systems. We never want customers to think twice about the quality of the water coming from their taps.

2023 General Rate Case (2025-27)

The rates adopted for 2025-2027 will provide customers with long-term value by investing over $11.9 million in needed capital investments and maintenance of local water infrastructure essential to the reliable production, treatment, and delivery of quality water.

Investments in the San Gabriel Service Area include, but are not limited to, water distribution projects, construct a new reservoir, construct a booster station and replace another booster station, a new well, systemwide technology to monitor and control the water system, and emergency generators needed for uninterrupted production, treatment and delivery of water in the event of power outages and natural disasters and to reduce the strain on the electrical grid, and the replacement of aging water mains. As part of our commitment to reliability and public safety, Golden State Water proactively invests in upgrading and maintaining its fire hydrants.
