Sewer Service Rate Increase Essential
To Meet New Federal Regulatory Requirements

Triunfo Sanitation District (TSD) 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. Our rates for that service are competitive with other agencies in the area (click here to view a comparison).

On May 21, 2018, the TSD Board of Directors approved a series of 2.5% annual sewer service rate increases, over and above the current approved rate plan, as well as future rate plans covering the next six years. These increases are essential to address new federal regulatory requirements associated with the discharge of recycled water into Malibu Creek from the Tapia Water Reclamation Facility. These regulations require that the water be treated to new levels exceeding drinking water standards.

In partnership with Las Virgenes Municipal Water District, TSD has begun development of the Pure Water Project, an innovative, cost-effective effort that will fully satisfy the new environmental regulations. As an added benefit, the project will simultaneously reduce the region’s dependence on costly water imported from outside the area and enhance local water supply reliability. After extensive study by an independent consultant, and review by a wide range of stakeholders, the project was selected as the most effective and cost-efficient option to address the environmental issue.

The Pure Water Project is estimated to cost $100 million, and TSD’s share of that cost is approximately $30 million. Our financial plan includes potential funding from state and federal grants and low-interest loans, as well as local funding. In order to qualify for grants, TSD must satisfy matching fund requirements. The District’s Board of Directors has identified $6 million as the “pay-go” (ratepayer-funded) target for that purpose, to be funded by the series of 2.5% rate increases. Maximizing TSD’s ability to obtain grants and low-interest loans will enable the District to minimize costs to its customers.

While higher rates are never welcome, the need for the Pure Water Project is critical. The TSD Board of Directors remains committed to minimizing its cost impact on customers, while at the same time ensuring high-quality, reliable service that meets all regulatory requirements. The initial 2.5% increase takes effect on July 1, 2018.
