Pure Water San Diego is the City’s 20-year program to provide a safe, reliable and cost-effective drinking water supply for San Diego. Proven technology will be used to purify recycled water.

The program is environmentally friendly and will make San Diego more water independent and more resilient against drought, climate change and natural disasters.

Pure Water San Diego (PDF) program components include the construction of water purification facilities, continued operation of the test Advanced Water Purification Facility, research on additional treatment barriers for a potential direct potable reuse project, regulation and legislation development, and an education and outreach program.

An initial 15-million gallon per day water purification facility is planned to be in operation by 2023. The long term goal, producing 83 million gallons of purified water per day (one third of San Diego's future drinking water supply), is planned to be reached by 2035.

The City offers free tours of the Advanced Water Purification Facility. Register for a tour here.

Presentations to all interested groups are also available. Request a presentation here.
