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% 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 phased, multi-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.
