Golden State Water provides reliable, high-quality drinking water to approximately 11,000 customers in the Claremont Customer Service Area (CSA), which includes Claremont and portions of Montclair, Pomona and Upland. Our local team includes 11 dedicated employees who take pride in serving Claremont customers 24/7.
Local water comes from two sources: 60 percent comes from local groundwater supplies, which Golden State Water maintains, and the balance is imported from the Metropolitan Water District of Southern California (MWD) via Three Valleys Municipal Water District.

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 June 8, 2019, an average residential customer in the Claremont Customer Service Area with a 1” meter using 18 Ccf per month would see a monthly bill decrease of $1.66 from $108.23 to $106.57 compared to 2018 (excluding any applicable surcharges).
- 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. Click here to learn more.
- On July 1, 2018, local water rates decreased by 3.21% to pass cost savings from the new lower federal corporate income tax requirement through to customers. Click here to learn more.
