Since 1962, the Sanitation Districts have been producing recycled water that provides a reliable, drought-resistant source of water for the region.  Most of the cleaned water from 10 of our 11 wastewater treatment plants is reused—mainly for groundwater replenishment. Our last untapped source of recycled water is the cleaned water produced by our A.K. Warren Water Resource Facility. That water is too salty to reuse without advanced treatment. 

The Pure Water Southern California (Pure Water) program would purify the treated water from the Warren Facility and could provide enough water for 1.5 million people. This program is a partnership between the Sanitation Districts and the Metropolitan Water District of Southern California (MWD).  Pure Water is now in its environmental planning phase and could become one of the largest water recycling projects in the world.
