Encinitas, Calif. — Olivenhain Municipal Water District’s Ultraviolet Disinfection System Project was recognized today as a 2021 Project of the Year by American Public Works Association’s San Diego and Imperial County Chapter at its virtual awards event.

The UV project replaced an outdated system at OMWD’s 4S Ranch Water Reclamation Facility in order to continue serving high-quality recycled water. 4S WRF treats and disinfects wastewater for use as tertiary treated recycled water throughout 4S Ranch and the southeastern portion of OMWD’s service area. It can produce up to two million gallons of this alternative water supply for irrigation at schools, parks, golf courses, streetscapes, and homeowner association common areas.
