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 Sept. 27, 2019, an average residential customer in the Los Osos Customer Service Area would see a monthly bill increase of $0.090 per 748 gallons (1 Ccf), or approximately 0.6 percent, during the 12-month amortization period.
  • Effective June 8, 2019, an average residential customer in the Los Osos Customer Service Area with a 5/8 x 3/4” meter using 6 Ccf per month would see a monthly bill increase of $1.55 from $77.11 to $78.66 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)
  • On July 1, 2018, local water rates decreased by 4.37% to pass cost savings from the new lower federal corporate income tax requirement through to customers. Click here to learn more.
Golden State Water plans to invest approximately $115 million companywide for infrastructure projects in 2019, because proactive system maintenance is critical to protecting water service now and for future generations.

More than $500,000 in infrastructure improvements are planned for 2019 in the Los Osos service area.

The 2019 investments include water supply enhancements, distribution and ongoing improvements designed to replace old meters, mains and safety equipment. Click here to learn more and access a list of projects planned for 2019.

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.
