Story

To protect public health and the environment and enable planned growth, King County will push forward with plans to upgrade a major sewer line continually serving southeast Snohomish County and Bothell since 1970.

King County purchased the North Creek Interceptor from the Alderwood Water & Wastewater District in 2001. During heavy storms last winter, high water volumes caused several manholes along the 43-year-old line to overflow into North Creek.     

Construction on a long-range plan to add needed capacity to the line to accommodate population growth will begin in 2014. In the meantime, County staff have already initiated a series of short-term inspection, repair and maintenance projects to prevent overflows and backups.

This summer, County crews will complete repairs on several manholes near North Creek and Centennial parks. Neighbors will be notified before work begins.

King County will continue to coordinate closely with the state Department of Ecology in completing these vital projects.

The North Creek Interceptor carries wastewater collected from homes and businesses in unincorporated Snohomish County and the City of Bothell for treatment at the Brightwater Treatment Plant north of Woodinville.
