Central Basin East

Overview May 28, 2020

Golden State Water is committed to serving nearly 20,000 customers in the Central Basin East Service Area, including portions of Artesia, Cerritos, Downey, Hawaiian Gardens, La Mirada, Lakewood, Long Beach, Norwalk, Santa Fe Springs, and adjacent county territory. We’ve been serving high-quality, reliable water to the area for more than 80 years.

Two water systems serve the Central Basin East CSA. Water delivered to customers in the Artesia System is a blend of groundwater pumped from the Central Groundwater Basin. Water delivered through the Norwalk System is a blend of groundwater pumped from the Colorado River Aqueduct and the State Water Project.

Drought

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.

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. Click here to learn more. Learn more about the rate-making process and localized information on new rates and investments in the Central Basin East GRC Fact Sheet.

The average residential customer in the Central Basin East Customer Service Area with a 5/8 x 3/4” meter using 6,732 gallons (900 cubic feet or 9 Ccf) per month will see their monthly bill increase from $58.67 to $68.20 (excluding any applicable surcharges).

The average commercial customer in the Central Basin East Customer Service Area with a 5/8 X 3/4” meter using 26,928 gallons (3,600 cubic feet or 36 Ccf) per month will see their monthly bill increase from $188.82 to $221.80 (excluding any applicable surcharges).

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.

On July 15, Golden State Water filed a GRC application for the years 2022, 2023, and 2024. Learn more: 2022-24 GRC Fact Sheet

On May 30, 2019, Golden State Water’s GRC was approved by the State of California to set water rates for 2019, 2020 and 2021 and authorize infrastructure investments for the local system. New rates were implemented effective June 8, 2019. Learn more here. (English| Spanish)
