Environmentally Sound ~ The Advanced Water Purification Program is a potential new source of water that would be locally controlled, reliable, drought-proof and environmentally sound. The demonstration facility produces approximately 100,000 gallons of purified water each day, which is vigorously tested to ensure high quality water standards are being met. The water produced during this phase is not utilized in the drinking water system. The demonstration project was funded through a three million dollar Prop 50 grant from the Department of Water Resources. MEMBRANE FILTRATION MAGNIFIED ADVANCED OXIDATION REVERSE OSMOSIS MAGNIFIED FREE CHLORINE DISINFECTION The Process ~ Padre Dam's Advanced Water Purification Demonstration Project takes recycled water through four advanced water treatment steps: free chlorine disinfection, membrane filtration, reverse osmosis and ultra violet/advanced oxidation. The demonstration project will operate for at least 12 months. During this time, the demonstration project will produce approximately 100,000 gallons of purified water per day. The water will be tested daily to ensure it meets the public health objectives for California Health Department approval. If the demonstration project is deemed successful and the project moves forward, the water would be injected into the Santee groundwater basin where it would be naturally filtered, then withdrawn and treated again prior to distribution as drinking water. The project would have the potential to provide up to three million gallons of water per day. Additionally, Padre Dam is working with Helix Water District, the City of El Cajon and the County of San Diego to study the feasibility of developing an expanded East County Advanced Water Purification Program. The study focuses on the possibility of expanding Padre Dam's proposed Advanced Water Purification Project to accommodate and treat wastewater from the other agencies' service areas in order to provide a recycled water supply for local and regional groundwater recharge, reservoir augmentation and other potable reuse opportunities. This expanded program could produce up to an additional 10 million gallons of water per day or 30 percent of the local water supply for East San Diego County.

Our new Advanced Water Purification Demonstration Project broke ground in October 2014 and began operations and offering public tours in April 2015. ~ 9 2015 Annual Report
