Project update

July 2017

Drilling and grouting along West Galer Street is complete. King County's contractor restored the work area near Thorndyke Avenue West in June.

The County and its contractor continue work on a plan to bring the pipe into service. We will share the plan with you before starting work.

For more information about the project, check out the presentation from our Feb. 16 community update.

Magnolia Wet Weather Storage Facility The Magnolia Wet Weather Storage Facility at Smith Cove began storing excess flows of stormwater and sewage in late 2015. The facility’s 1.5 million-gallon underground storage tank helps keep sewage and stormwater out of Puget Sound during storms.

King County is Protecting our Waters

This project is part of King County’s Protecting our Waters program to prevent pollution caused by excess stormwater in the sewer system on rainy days.

Combined sewer overflows (CSOs) are relief points in older sewer systems that carry sewage and stormwater in the same pipe. When heavy rains fill the pipes, CSOs release sewage and stormwater into rivers, lakes, or Puget Sound.

King County and the City of Seattle are working together to control CSOs and keep sewage and stormwater out of local waterways.
