Pure Water San Diego
Pure Water San Diego is the City's phased, multi-year program to use proven water purification technology to clean recycled water 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), will be reached in 2035.
Pure Water San Diego Program components include:
- The design and construction of full-scale water purification 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.
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.
