The Groundwater Replenishment System (GWR) is located in Orange County and receives secondary treated sewer water for further treatment. H2O at the existing plant is treated using advanced techniques consisting of microfiltration, reverse osmosis (RO) and ultraviolet disinfection with hydrogen peroxide. The source, which is secondary treated sewer water, is first micro-filtered to remove small suspended particles, protozoa, bacteria and other harmful viruses. In the final stage, the water is treated with ultraviolet light and hydrogen peroxide as a precautionary measure. The existing plant generates enough water to supply 500,000 people. It is estimated that in the next 20 years the population of Orange County will increase from 2.3 million to three million people. Nearly half of the refined H2O is transferred to the Orange County Water District in Anaheim. Any remaining is injected into Orange County’s seawater barrier for its expansion. The expansion will increase the plant’s treatment capacity by 30 million gallons a day. In an effort to provide a greater understanding to the public regarding current and emerging issues affecting Orange County, a Water Advisory Committee has been created. Various pertinent topics will be discussed and meetings are generally held the first Friday of the month at 7:30 am.

Interesting facts from far and away:  A new Wastewater Plant has just opened in Rio de Janeiro, Brazil in time for the Olympic events to be held in August.
