Demonstration Facility

Advanced Water Purification Demonstration FacilityThe Advanced Water Purification Demonstration Facility proves the feasibility of purifying recycled water to create a new drinking water supply. This Demonstration Facility uses the same processes that will be used in the full-scale Advanced Water Purification Facility to produce around 100,000 gallons of water a day.

Operating since March 2015, this pilot facility has allowed partner agencies to run water quality studies and tests confirming that it is possible to produce clean, safe, reliable drinking water that meets all state and federal standards. Data collected from the produced water has helped the full scale Program earn approval from the State Water Resources Control Board’s Division of Drinking Water. After providing valuable information for Program engineers and operators, the water produced by the Demonstration Facility is reused in Padre Dam’s recycled water program.


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.
