The Stuck River Trunk is now operational!

Final restoration activities are ongoing and expected to be complete by the end of the month, weather dependent.

Project description

To protect public health and the environment, the King County Wastewater Treatment Division is building two new pipelines, the Kent East Hill Diversion in Kent and the Stuck River Trunk in Auburn. The new pipelines will provide the required capacity to accommodate recent and projected growth in Kent and Auburn and will allow King County to continue to provide safe, reliable sewer service.

Providing additional sewer capacity will protect public health by reducing the chance of sewer overflows into homes and streets. The new pipelines will provide sufficient capacity to meet Kent and Auburn’s needs through 2050.
