Olivenhain Municipal Water District serves nearly two million gallons of recycled water every day, continuing a tradition that began in California in 1929.
OMWD currently collects wastewater from 4S Ranch and Rancho Cielo areas, which enters the recycling process at 4S Ranch Water Reclamation Facility, located at 16595 Dove Canyon Road in San Diego. The facility produces over one million gallons of recycled water per day which is delivered to irrigation customers in the southeastern portion of OMWD’s service area for use at HOA common areas, schools, parks, streetscapes, and golf courses. OMWD supplements the recycled water it produces with recycled water purchased from Rancho Santa Fe Community Services District and the City of San Diego.
OMWD also purchases recycled water from Vallecitos Water District and San Elijo Joint Powers Authority to serve customers in portions of Encinitas and Carlsbad. OMWD continues to expand recycled water infrastructure throughout the area. In 2016, OMWD completed Village Park Recycled Water Project that included the installation of approximately 7 miles of pipeline to bring recycled water service to Village Park community of Encinitas.
OMWD’s recycled water is highly treated and used for non-domestic purposes. OMWD has adopted “Best Management Practices” to ensure that this water is used in a safe and responsible manner. First, irrigating with recycled water must take place during the late evening and early morning hours, when public contact is at a minimum. Second, OMWD staff actively oversees the use of the recycled water.
