Golden State Water has proudly served the San Dimas Customer Service Area since 1976. With more than 16,000 customers, Golden State Water serves residents in portions of Charter Oak, Covina, Glendora, La Verne, San Dimas and Walnut. This location has 13 local employees serving customers 24/7.

Water delivered to customers is a blend of groundwater pumped from the Main San Gabriel Basin and purchased water from the Metropolitan Water District of Southern California and 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 April 20, 2017, an average residential customer in the San Dimas Customer Service Area with a 5/8 x 3/4” meter, using 8,976 gallons (1,200 cubic feet or 12 Ccf) of water per month, would see a monthly bill increase of $5.05 from $54.72 to $59.77 compared to 2016 (excluding any applicable surcharges).
  • Effective July 1, 2018, local water rates will decrease by 3.21% to pass cost savings from the new lower federal corporate income tax requirement through to customers. Click here to learn more.
  • Golden State Water’s rates for 2016, 2017 and 2018 were approved by the CPUC in March 2017. The GRC approval was originally expected prior to Jan. 1, 2016, and the delayed approval prevented Golden State Water from implementing the new rates for 2016 on schedule (2015 rates remained in place during the delay period).
