Demonstration Facility

Advanced Water Purification Demonstration Facility

The Advanced Water Purification Demonstration Facility was in operation from March 2015 through October 2021. It proved the feasibility of purifying recycled water to create a new drinking water supply. This Demonstration Facility used the same purification processes that will be used for the full-scale Advanced Water Purification Program (Program) to produce around 100,000 gallons of water a day.

The pilot facility allowed partner agencies to run water quality studies and tests confirming that the purification processes produce clean, safe, reliable drinking water that meets all state and federal standards. Data collected from the produced water helped earn the approval for the full scale Program from the State Water Resources Control Board’s Division of Drinking Water. The water produced by the Demonstration Facility was reused in Padre Dam Municipal Water District’s recycled water program.

FUNDING

Funding for the Advanced Water Purification Demonstration Facility was provided through a $3 million grant secured through the California Department of Water Resources Proposition 50 through San Diego’s Integrated Regional Water Management Group. The planning, design, installation and operation of the demonstration facility was not paid for by Program Partners.
