Advanced purified water first flowed from Pure Water Oceanside on Dec. 30, 2021, making the site the first operational indirect potable reuse facility in San Diego County, Calif. The project treats the City of Oceanside’s wastewater flows and, after additional residence time in the ground and further treatment, will distribute the finished purified drinking water to city customers later this summer.

The $71 million project took eight years of planning and two years of construction during the height of the coronavirus pandemic.
