Innovative project in San Diego County to bring significant benefits for future generations


The East County Advanced Water Purification Program has been strategically planned for many years as a regional water and wastewater solution.

This program is a collaborative partnership between Padre Dam Municipal Water District, the County of San Diego, the City of El Cajon and Helix Water District. It is designed to create a new, local, sustainable and drought proof drinking water supply using state-of-the-art technology to purify recycled water and diversify East County’s water supply while reducing our dependence on imported water. Scheduled to be complete in 2025, the project will generate up to 11.5 million gallons per day of new drinking water, which is approximately 30 percent of East County’s drinking water demands for residents in East San Diego County.

In October of 2019, the East County Advanced Water Purification project was selected by the U.S. Environmental Protection Agency (EPA) to apply for $342 million in funding from the Water Infrastructure Finance and Innovation Act (WIFIA) loans. The project was one of only 38 projects selected across 18 states to apply for loans totaling approximately $6 billion to help finance over $12 billion in water infrastructure investments and create almost 200,000 jobs.
