Through a Joint Exercise of Powers Agreement (JPA), Las Virgenes Municipal Water District (LVMWD) and Triunfo Sanitation District (TSD) jointly own and operate Tapia Water Reclamation Facility, which provides wastewater treatment for more than 80,000 residents of western Los Angeles County and eastern Ventura County. Tapia transforms wastewater into highly treated recycled water, which is sold to irrigate public landscapes such as schoolyards, golf courses, playgrounds, and highway medians.
