Joining over 200 other water agencies throughout California, Dublin San Ramon Services District has embarked on a water recycling program to help meet that goal. Recycled water is a safe and reliable resource for irrigation and other uses, and with appropriate treatment, can replenish potable water supplies such as rivers, groundwater basins, and reservoirs. Many communities in the Bay Area use recycled water for irrigation of pastures and food crops, as well as landscape irrigation of schools, parks, and golf courses. In addition, recycled water can be used for recreation, habitat restoration and commercial uses such as carpet dying, paper production, heating and cooling. Many other communities across the nation have implemented projects to use purified recycled water to supplement drinking water supplies.
Some communities use reverse osmosis and others use less advanced technologies.
Orange County, California The Orange County Water District currently injects recycled water into depleted groundwater basins. West Basin Water District uses microfiltration, reverse osmosis and ultraviolet light technologies to treat recycled water for groundwater injection. A neighboring water district, the Water Replenishment District of Southern California, has been inspired to construct a similar water treatment facility. Scottsdale, Arizona The City of Scottdale's new wastewater treatment plan uses microfiltration and reverse osmosis to purify treated wastewater before it is injected into the groundwater basin. Los Angeles County Treated wastewater runs through dual media filters at the Montebello Forebay Groundwater Recharge Project and is discharged into the Rio Hondo River.
