Triunfo Water & Sanitation District

What Triunfo Water & Sanitation District does

Triunfo Water & Sanitation District is a California special district organized in 1963 under California Health and Safety Code that provides exclusive potable water distribution, wastewater collection and treatment, and recycled water services to more than 30,000 residents across a 50-square-mile service area in east Ventura County, including Oak Park, Lake Sherwood, Bell Canyon, and portions of Westlake Village and Thousand Oaks. The district operates a vertically integrated utility infrastructure consisting of 120 miles of sewer pipeline, 54 miles of water pipeline, four storage reservoirs, five pumping stations, and a 10-mile recycled water network, with system-wide smart metering installed in 2015 via the Sensus Analytics platform. The Tapia Water Reclamation Facility (16 MGD treatment capacity, currently averaging ~9.5 MGD) is jointly owned through a 1964-established Joint Powers Authority with Las Virgenes Municipal Water District, and the JPA is now building the Advanced Water Purification Facility for the Pure Water Project, expected to produce up to 1.6 billion gallons of locally sourced drinking water annually by 2030.

The district's business model is a regulated utility franchise: it is the exclusive provider in its service area, collects water service revenue through direct monthly billing and sewer fees through Ventura County property tax assessments, and sets rates via ordinances (TWSD-250 sewer, TWSD-350 potable, TWSD-450 recycled). A 5-year sewer rate plan approved in May 2025 implements 7% annual increases through 2029. The customer base is dominated by residential connections (85% of 10,826 sewer connections), with retail (10%) and commercial (5%) accounting for the remainder; supplemental recycled water customers include HOAs, golf courses, and parks. Customer-facing infrastructure includes a Sensus Analytics real-time usage portal and a Paymentus-powered online bill-pay system, with a new bill-pay portal launched in January 2026. The district is governed by a five-member elected Board of Directors, holds the GFOA Award for Excellence in Financial Reporting, and operates with 11-50 employees from its Westlake Village headquarters.

• Las Virgenes Municipal Water District: Triunfo's JPA partner since 1964, Las Virgenes MWD is a similarly sized Southern California special district that jointly owns the Tapia Water Reclamation Facility and is co-developing the Pure Water Project. Operates an overlapping water/wastewater utility model in adjacent eastern Ventura and western Los Angeles County territory.
• Casitas Municipal Water District: Ventura County-based special district providing treated water and recycled water services. Operates Lake Casitas as a local surface water source — a relevant comparison point for Triunfo's strategic interest in local supply diversification.
• Eastern Municipal Water District: California special district providing water, wastewater, and recycled water services to roughly 175,000 customers in Riverside County. Operates a comparable three-product utility model (potable/wastewater/recycled) with similar regulatory and rate-making framework.
• Western Municipal Water District: Riverside/San Bernardino area special district offering potable water, wastewater, and recycled water services. Comparable size, multi-product utility model, and Southern California climate exposure to Triunfo.

Regional players

• Camrosa Water District: Nearby Ventura County water district serving the Santa Rosa Valley area with potable and recycled water services. Comparable small-scale California special district model with similar regulatory and rate structures.

Broad incumbents

• Metropolitan Water District of Southern California: The regional wholesaler that delivers 1.5 billion gallons/day to 19 million Southern Californians and is Triunfo's ultimate imported water supplier. Operates at vastly greater scale but anchors the same water supply chain.
• Sanitation Districts of Los Angeles County: Large regional wastewater treatment agency serving much of Los Angeles County. Operates the Joint Outfall System and numerous reclamation plants; relevant comparable for Triunfo's wastewater treatment operations at scale.
