The District will judiciously manage its assets and finances, effectively plan for future needs, protect the environment, and work to maintain public trust and confidence.

Our History

The Beginning

Triunfo Sanitation District was organized in 1963, pursuant to California Health and Safety Code Division 5, Part 3, Chapter 3, Section 4700, as a special district to provide sewer services for the eastern portion of Ventura County. At that time, the Board of Directors consisted of two elected and three appointed members.

A year later, Triunfo and Las Virgenes Municipal Water District established a Joint Powers Authority (JPA) to construct, operate, and maintain a regional sewage collection and treatment system to serve customers in their respective service areas. In 1977, Triunfo contracted with Ventura Regional Sanitation District for operation, management, and maintenance services.

Service Expansion

In 1993, Triunfo expanded its operations to include potable water service with the purchase of Metropolitan Development’s Metropolitan Water Company, located within the District’s service area in Oak Park. The new entity became known as Oak Park Water Service. In 2019, Triunfo added “Water” to its name and integrated the operations of Oak Park Water Service into the single entity of Triunfo Water & Sanitation District.

Triunfo also supplies recycled water for irrigation of parks, schoolyards, homeowner association landscapes, and roadway greenbelts. In 2017, the District expanded that service, and increased its operating efficiency, with the purchase of Calleguas Municipal Water District’s recycled water system.

Current Operations

Triunfo is now governed by a five-member all-elected Board with a dedicated management staff that oversees Ventura Regional Sanitation District’s contract operation and maintenance services. Covering a service area of approximately 50 square miles, the District provides wastewater collection and treatment services to more than 30,000 people in Oak Park, Lake Sherwood, Bell Canyon, and the Westlake Village and North Ranch portions of Thousand Oaks. Triunfo supplies potable water to more than 14,000 people in Oak Park and provides recycled water to various portions of its service area.

Board of Directors

Triunfo Water & Sanitation District is governed by a five-member Board of Directors, each elected at large to a four-year term. District elections are held every two years in November on even-numbered years. Terms are staggered, with two terms expiring in one even-numbered year, and three terms expiring the following even-numbered year.

The Board of Directors meets on the fourth Monday of each month at 5:15 p.m. in the Film and Lecture Room of the Oak Park Library, 899 N. Kanan Road, in Oak Park. Meeting agenda packets are available via the link below.

Las Virgenes-Triunfo Joint Powers Authority

In 1964, a Joint Powers Authority partnership was established between Triunfo Water & Sanitation District and Las Virgenes Municipal Water District to cooperatively treat wastewater in the Malibu Creek watershed. The Tapia Water Reclamation Facility began operating in 1965 and had an initial capacity of 0.5 million gallons per day. In 1972, the plant began to produce recycled water for landscape irrigation. As a result of population growth in the 1980s and 1990s, the JPA expanded Tapia’s treatment capacity to its current level of 16 million gallons per day.

The JPA’s latest major initiative is the innovative Pure Water Project. Using “potable reuse,” a water supply strategy used by many cities and water agencies in California and across the United States, the project will enhance local water supply reliability and drought resilience, while eliminating discharges of treated water from the Tapia plant into Malibu Creek.

The Joint Powers Authority Board, made up of the combined boards of both districts, meets on the first Monday of each month and alternates the meeting locations between the Oak Park Public Library and the Las Virgenes Municipal Water District office.
