Tapia Water Reclamation FacilityThe proper treatment of wastewater is a function critical to the health and safety of everyone in the region. It is also environmentally protective of those who live downstream. As environmental awareness escalated in the mid-20th century, it became apparent that many of nation’s waters were greatly impaired. As a result, the federal Clean Water Act and its extensive body of law was adopted in the early 1970s, with the partial objectives of building facilities to treat wastewater and to clean up watersheds that had become impaired. Out of that legislation came the National Pollution Discharge Elimination System (NPDES) that regulates and issues permits for wastewater treatment facilities. 

Federal, state and local partnerships helped fund much of the needed construction and over several decades, many regions saw significant improvements in water quality. In our region, Las Virgenes Municipal Water District and the Triunfo Sanitation District (that serves a portion of Ventura County) share a service area in the Malibu Creek watershed. The Tapia Water Reclamation Facility and the Rancho Las Virgenes Composting Facility are owned by the Las Virgenes – Triunfo Joint Powers Authority and operated by LVMWD personnel.

As the region grew, the Tapia facility was expanded several times and in 1988 it was honored by the U.S. EPA for excellence in operations and maintenance.

Each day, the Tapia facility processes about 9.5 million gallons of wastewater, turning it into tertiary-treated, Title-22 compliant recycled water that is used to irrigate golf courses, parks, school grounds, highway landscapes and common areas of some housing developments. Biosolids removed from the wastewater are then sent to the Rancho Las Virgenes Composting Facility, where they are converted to U.S. EPA “Class A – Exceptional Quality” compost for use as a soil amendment in local gardens.

For more information on these facilities, download the “Bringing Water Service Full Circle” brochure. The brochure is also available in printed form at LVMWD headquarters, 4232 Las Virgenes Rd, in Calabasas.
