Project description

The County is completing construction to repair and replace a 2-mile pipeline that has been serving the Bothell area since 1970. The new pipeline will increase system reliability and accommodate population growth in this portion of the service area. 

The new pipes are being installed using both trenchless and open cut construction methods. Work includes dewatering operations and pipeline decommissioning. The areas where work will occur for the project are listed on the project map (below) from north to south.


King County began work in early 2015. Project completion is expected in early 2018.
