A Regional Solution

AWP_ServiceAreaMap_Website_11.16.21The East County Advanced Water Purification Program will create a new, local, reliable and drought-proof drinking water supply utilizing state-of-the-art technology to recycle and reuse the region’s wastewater. The program is a collaborative partnership between Padre Dam Municipal Water District, Helix Water District, County of San Diego and the City of El Cajon.

The program is the result of several years of strategic, long-term planning and provides numerous benefits in addition to serving as a sustainable model of water recycling and reuse for other water agencies throughout California and the nation.


The partners for the East County Advanced Water Purification Program currently produce 15 million gallons per day of wastewater. Most of this wastewater is transported to the City of San Diego’s Metropolitan Wastewater System in Point Loma to be treated and released into the ocean.


Instead of relying on and paying the City of San Diego to treat and discharge East County’s wastewater, this program would treat and recycle the locally using state-of-the-art technology to create a safe, sustainable supply of drinking water.


By providing East County with local control and independence of both its wastewater and water, the program secures a long term solution for increased stability in our communities and safeguards the vitality of East County’s economy and quality of life.
