Pure Water Demonstration Facility – Public Tour Schedule

Since June 2011, the City's one-million-gallon-per-day Pure Water Demonstration Facility has been open for free public tours. Participating in a tour is a great way to learn about the water purification process and get an up-close look at the cutting-edge technology used to clean recycled water to produce safe, high-quality drinking water. You will also find out how the City plans to use the technology to produce nearly half of San Diego’s water supply locally by 2035.

Tours last approximately one hour and include an introductory presentation and a walking tour of the facility. At the end of the tour, participants have the opportunity to taste a sample of the purified water.

The Pure Water Demonstration Facility is located at the North City Water Reclamation Plant, off the I-805 and Miramar Road at 4949 Eastgate Mall, San Diego, CA 92121. You must register in advance.

As of October 2021, tours of the Pure Water Demonstration Facility are on hold.

Can't visit in person? Virtual tours of the Pure Water Demonstration Project are also available.
