Pure Water San Diego Program

The City of San Diego is addressing the need for a new locally controlled, drought-proof water supply. The City currently depends on importing 85 percent of its water from Northern California and the Colorado River. A Water Reuse Study, Recycled Water Study and Water Purification Demonstration Project determined that it is feasible for San Diego to use water purification technology to produce one third of San Diego's drinking water supply locally by 2035. Pure Water San Diego, the City's 20-year program to produce purified water to supplement San Diego's drinking water supply, is underway. Learn more about each phase of the program at the links below.
