Central Basin East

Overview

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, Los Alamitos, Norwalk, Santa Fe Springs, Whittier 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.

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, every three years 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.

Effective July 31, 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.
