Claremont

Overview May 28, 2020

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.

Drought

Golden State Water has activated its Staged Mandatory Water Conservation & Rationing (Schedule 14.1) filings that outline restrictions, water allocations, enforcement measures and surcharges designed to achieve reductions due to water supply shortages or to achieve identified water usage goals established by an authorized government agency or official.

The Claremont community is in Stage 2. Under this stage, all outdoor irrigation is limited to (1) one-day-per week and is banned between the hours of 9 am – 5 pm. Watering is limited to eight (8) minutes per controller station or valve.

Golden State Water customers who do not meet the Stage 2 mandatory 20% reduction in water use will be charged a drought surcharge of up to $2.50 per Ccf (or 748 gallons) for all usage in excess of the customer’s usage allocation.

Addresses Ending In	Watering Days	Duration
Even Numbers (0, 2, 4, 6, 8)	Monday	8 min. per controller station/valve
Odd Numbers (1, 3, 5, 7, 9)	Wednesday	8 min. per controller station/valve

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.
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. Learn more here. (English| Spanish)
