Golden State Water has proudly served the Los Osos area since 1976, providing high-quality and reliable water to approximately 3,300 customers in Edna Road and Los Osos.

Two water systems serve the Los Osos Customer Service Area. Water delivered to customers in the Edna Road System is groundwater, which is pumped from the Edna Valley Basin through wells operated by Golden State Water. Water delivered to the Los Osos System is groundwater pumped from the Los Osos Valley Groundwater Basin through wells owned and operated by Golden State Water.

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 Los Osos CSA with a 5/8 x 3/4” meter, using 5,236 gallons (700 cubic feet or 7 Ccf) of water per month, would see a monthly bill increase of $17.88 or 24.3% from $73.68 to $91.56 excluding any applicable surcharges.
  • 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).

On April 7, 2017, Governor Jerry Brown issued an executive order lifting the drought emergency for most of the state, while asking Californians to continue using water responsibly and make conservation a way of life.

Local water-use and outdoor irrigation restrictions implemented during the drought emergency have been lifted for Los Osos customers.

Due to local conditions, Edna Road customers are in Stage 2 of Mandatory Water Conservation and Rationing (Schedule 14.1) and have been assigned allocations for each billing period to achieve a 25% reduction, compared to 2013. Outdoor irrigation is limited to two days per week, as noted below. Click here to review the conservation requirements for Edna Road customers.
