About Recycled Water

Recycled water is wastewater effluent that has been further treated and disinfected to provide a non-potable (non-drinking water) water supply. Recycled water is safe and suitable for uses such as landscape irrigation and some industrial processes. Recycled water is widely used and accepted throughout the United States as an environmentally responsible way to conserve scarce and expensive water supplies. It has been successfully used in other communities in California and other parts of the country such as Arizona, Florida, Hawaii, Texas, and Colorado. Recycled water is the fastest growing water supply in California.
