Story

Heavy overnight rains caused at least four manholes to overflow near Thrasher’s Corner in Bothell early Thursday morning.

An undetermined amount of highly diluted wastewater overflowed from the North Creek Trunk, which is a major regional sewer line that collects wastewater from homes and businesses for treatment at the Brightwater Treatment Plant north of Woodinville. The overflows occurred in neighborhoods east of the Bothell-Everett Highway between 201st Place Southeast and 214th Street Southeast.

King County reported the overflows to health and regulatory agencies and posted affected areas as closed. Employees with the County’s environmental laboratory will sample and monitor water quality in North Creek over the next few days.

The North Creek Trunk has been in service since about 1970. King County purchased the line from the Alderwood Water & Wastewater District in 2001, and has a long-term capital plan to upgrade the line and add capacity in this portion of the service area.
