Rigorous Demonstration Process


KC 11.17.15 Padre Dam 494Padre Dam’s demonstration project is evaluating the feasibility of the Advanced Water Purification Program. Since March 2015, the pilot program has produced approximately 100,000 gallons of purified water each day. The water treated at the demonstration facility is not being distributed into the drinking water system, but instead is being reused in the recycled water system.

The purified water produced at the demonstration facility is tested daily to ensure it meets the public health objectives to earn approval from the State Water Resources Control Board’s Division of Drinking Water.

If Padre Dam’s demonstration project is deemed successful and the Advanced Water Purification Program moves forward with a full-scale project, the treatment process would continue with additional steps that would include injecting the water into a groundwater basin or blending it with water in the Lake Jennings reservoir, before being withdrawn and treated again prior to being distributed as drinking water.

The ultimate goal of the Advanced Water Purification Program is to develop a proven full-scale program that produces approximately 25-30 percent of East County’s drinking water supply.

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 did not impact Padre Dam customers’ water rates.


Independent Advisory Panel


The Advanced Water Purification Program has an Independent Advisory Panel (IAP) that advises the program team to ensure an unbiased and thorough examination of the proposed water purification efforts. This panel of independent experts helps ensure that all important program components are thoroughly reviewed and analyzed.

Below is a list of the IAP members and their titles as experts in the fields of water and wastewater technology, public health, epidemiology, toxicology, water quality, economics and environmental science. Click here to see full IAP member bios.
