Pure Water San Diego is the City of San Diego's phased, multi-year program that will provide one-third of San Diego's water supply locally by the end of 2035. The Pure Water San Diego Program will use proven water purification technology to clean recycled water to produce safe, high-quality drinking water. The Program offers a cost-effective investment for San Diego's water needs and will provide a reliable, sustainable water supply.
Phase 1 includes several projects that will clean recycled water to produce 30 million gallons per day of high-quality purified water, reducing the City of San Diego’s dependence on imported water.
