Water Service

Potable Water Distribution System

Triunfo Water & Sanitation District supplies 2.6 million gallons of potable water daily to more than 14,000 people in the community of Oak Park. Our water distribution system consists of four storage reservoirs, five pumping stations, and 54 miles of pipeline. Triunfo purchases 100% of its water from northern California via the California State Water Project. Triunfo’s potable water service features system-wide automated water meters. Installed in 2015, these state-of-the-art devices have significantly improved meter accuracy. Additionally, customers can monitor their water use and set alarms to warn of excessive consumption.

Recycled Water

In addition to potable water service, Triunfo Water & Sanitation District supplies about 2 million gallons of recycled water each day (more than 2,200 acre-feet per year) for irrigation of public spaces such as parks and school grounds, homeowner association landscapes, golf courses, and roadway greenbelts. The recycled water is produced at the Tapia Water Reclamation Facility and conveyed through Triunfo’s service area through 10 miles of pipeline, a pumping station, and a storage reservoir.

The Las Virgenes-Triunfo Joint Powers Authority (JPA) is making FREE recycled water available to qualified residential customers at its recycled water fill station in Calabasas. Click here for information.
