King County is upgrading four miles of sewer pipeline across north Mercer Island and southwest Bellevue. In addition to the new sewer pipeline, King County will upgrade the County’s North Mercer Pump Station, as well as the City of Mercer Island’s Lift Station 11 at Fruitland Landing. The pipes, installed in the 1970s, are aging and reaching capacity.

The sewer upgrade is a big project that’s been years in the making and will involve years of construction. We expect construction to begin this fall and be complete in 2025. Some of the work will be in heavily used public spaces, and some will be in residential areas. The end product will provide great public benefit, but the work to get there will involve inconveniences to residents and park and trail users. We are committed to keeping you informed about what’s happening and why in order to minimize impacts wherever possible.
