Las Virgenes MWD

Triunfo Sanitation District

In 1964, the Las Virgenes - Triunfo Joint Powers Authority (JPA) was established between Las Virgenes and Triunfo Sanitation Districts to cooperatively treat wastewater for these two bordering areas, which share the Malibu Creek watershed. With the agreement in place, construction was begun of a wastewater treatment facility that would be named Tapia Water Reclamation Facility. Tapia began operating at 0.5 millions gallons per day in 1965. In 1972, the district began the practice of applying recycled water from Tapia to local landscapes.

In light of burgeoning local population in the late 1980s and early 1990s, Tapia's capacity was again expanded to its ultimate build-out of 16 million gallons per day. One year later, the JPA began operations at the Rancho Las Virgenes Composting Facility which transforms biosolids extracted from wastewater into market-ready soil amendment.

The JPA Board is scheduled to meet at 5 p.m. on the first Monday of each month.
