Claremont

Overview

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.

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.

  • On July 15, 2020, Golden State Water filed a GRC application for the years 2022, 2023 and 2024. Learn more: 2022-24 GRC Fact Sheet
  • Effective Sept. 27, 2019, an average residential customer in the Claremont Customer Service Area would see a monthly bill increase of $0.007 per 748 gallons (1 Ccf), or approximately 0.1 percent, during the 12-month amortization period.
