King County investigating sewer backup near Lake Ballinger pump station


King County is investigating a sewer backup near the Lake Ballinger pump station in Snohomish County.


King County Crews are investigating a sewer backup that occurred yesterday, March 14 near the Lake Ballinger pump station affecting approximately 12 properties adjacent to Lake Ballinger. A cleaning contractor is on location. There are no reports of sewage backing up into homes. We are taking precautions and have taken water quality samples from Lake Ballinger and have notified regulatory agencies. The unstaffed pump station moves area wastewater to the treatment plant.
