Pure Water San Diego
Pure Water San Diego is the City's phased, multi-year program to use proven water purification technology to produce a safe and sustainable high-quality water supply for San Diego. The program is a cost-effective investment for San Diego's future water needs and will provide a reliable drinking water supply that is locally-controlled and drought-proof.
An initial 30 million gallon per day water purification 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), is scheduled for 2035.
Pure Water San Diego (PDF) program components include:
- The design and construction of water purification facilities;
- Continued operation of the demonstration Advanced Water Purification 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.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.

A water reuse study (2004-2006) identified water purification via reservoir augmentation as the preferred water reuse strategy for San Diego.
A recycled water study (PDF) (2009-2012) developed and presented water reuse alternatives for San Diego's future.
A demonstration project (2009-2013) confirmed the City can produce purified water that meets all federal and state drinking water standards.
