California's Doheny Ocean Desalination Project to Produce 19 Million Liters of Potable Water Daily
The Doheny Ocean Desalination Project in Dana Point, California, aims to produce 19 million liters of potable water daily by utilizing five inclined wells buried under the Pacific Ocean. This initiative is designed to enhance local water supply security amid increasing demand and reliance on imported water.

The South Coast Water District's Doheny Ocean Desalination Project plans to install five inclined wells under Doheny State Beach, capable of extracting saline water. The project will produce approximately 5 million gallons per day (about 18.9 million liters), with operations expected to begin in 2029.
The use of subsurface intake aims to mitigate direct impacts on marine organisms and reduce visible infrastructure. Additionally, the project will manage brine disposal by combining it with treated effluent before release into the ocean.
It addresses California's growing water demand, projected to increase by 11% over 25 years, while also being part of a broader strategy that includes water conservation measures. Funding includes $40.1 million in grants, supporting its development and operation.
