Golden State Water is proud to be San Gabriel Valley’s water provider since 1929, serving high-quality, reliable water to approximately 12,300 customers in portions of Arcadia, El Monte, Irwindale, Monrovia, Monterey Park, Rosemead, San Gabriel and Temple City.

Two water systems serve the area. Water delivered to customers in the South Arcadia System is groundwater pumped from the Main San Gabriel Basin. The basin underlies the San Gabriel Valley from Alhambra to San Dimas. Water delivered to customers in the South San Gabriel System is a blend of purchased water from the Upper San Gabriel Valley Municipal Water District and groundwater pumped from the Main San Gabriel Basin.

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 Gabriel Customer Service Area with a 5/8 x 3/4” meter, using 8,228 gallons (1,100 cubic feet or 11 Ccf) of water per month, would see a monthly bill increase of $4.53 from $51.50 to $56.03 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).
