When it comes to managing wastewater, protecting public health is paramount. The goal of wastewater operations is to provide uninterrupted sanitary sewer conveyance and mitigate overflows into streams, lakes, and private property. That’s what keeps us on the leading edge of technology, system management, long-range maintenance, fiscal and environmental stewardship.

The District is in the wastewater collection business, not the treatment business. Through a complex system of pipes and lift stations over challenging hills and topography, all wastewater from the District’s system is conveyed to the King County Wastewater Treatment system, located in the south end of the District. King County then conveys the wastewater to the Renton South Treatment Plant for treatment and disposal.
