Pure Water San Diego

Pure Water San Diego is the City's phased, multi-year program that will provide one-third of San Diego's water supply locally by 2035. The Pure Water 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.

An initial 30-million-gallon-per-day Pure Water Facility is scheduled to be operational by 2021. The long-term goal, producing 83 million gallons of purified water per day (one-third of San Diego's future drinking water supply), will be reached in 2035.

Pure Water San Diego Program components include:

  • The design and construction of full-scale Pure Water Facilities;
  • Continued operation of the demonstration Pure Water Facility;
  • Research on potential additional treatment barriers;
  • Regulation and legislation development; and
  • An education and outreach program.

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