In 2009, the City of San Diego embarked on a demonstration project to examine the use of advanced water purification technology to provide safe and reliable water for San Diego's future. The Water Purification Demonstration Project (PDF) has evaluated the feasibility of a full-scale reservoir augmentation project, which would diversify San Diego's water supply, reduce its dependence on imported water and provide a reliable, local drinking water supply for residents.

The project's operational testing and monitoring verified the water purification process consistently produces water that meets all regulatory requirements and is similar in quality to distilled water. For more detailed information, a series of reports revealing all of the project's findings is available online for review. Although the initial studies are complete, the Demonstration Project continues to perform public outreach activities.
