Heavy rains cause manhole overflow in Bothell

Summary

Crews with King County’s Wastewater Treatment Division responded Thursday afternoon to a wastewater overflow from a manhole on the North Creek Interceptor, a major regional sewer line serving the Bothell area since 1970. A project that is now underway to add more capacity in the line is scheduled for completion in fall 2016.

Story

Persistent heavy rain on Thursday led to a manhole overflow on King County’s North Creek Interceptor, a sewer line in service since 1970.

The precipitation caused high water volumes in the pipeline, which carries wastewater from homes and businesses in the Bothell area to the Brightwater Plant for treatment. The overflow occurred near the intersection of 208th St. S.E. and 14th Drive S.E. in Bothell.

King County reported the overflow to health and regulatory agencies, and employees with the County’s environmental laboratory will sample and monitor water quality monitor water quality in North Creek over the next few days.

Construction is underway on a project that will upgrade the pipeline and add new capacity to support the growing community and increase system reliability.

King County’s North Creek Interceptor Project entails construction of approximately 10,000 feet of new sewer line. The project is scheduled for completion in September 2016.
