North Mercer Island/Enatai sewer upgrade
Project update
June 3, 2021
Lets Talk Mercer Island!
Construction is expected to start later this year on the Mercer Enatai Sewer Upgrade. The City of Mercer Island and King County are collaborating to ensure Mercer Island residents get timely, accurate construction information. In addition to the County’s website, Let’s Talk Mercer Island will feature the project as it moves into construction.
We will provide monthly updates on Let’s Talk, and we will monitor the site for resident questions and comments. And of course, as always, don’t hesitate to reach out directly with any questions or concerns you might have.Construction ahead
Major construction is set to begin later this year across north Mercer Island and southwest Bellevue. 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. View Spring Newsletter and Construction Reference Guide

Project description
With over 400 miles of pipes moving wastewater to one of our award-winning treatment plants, King County WTD works hard to maintain our system. We inspect and monitor our regional system and update plans for needed upgrades.
King County WTD needs to replace sewer pipes that serve areas in North Mercer Island, the southwest portion of Bellevue near Enatai Beach, and the Town of Beaux Arts Village. This pipeline carries wastewater from the North Mercer Island Pump Station to the Sweyolocken Pump Station in Bellevue.

Project design began in 2016 and will be complete in 2021. Construction is expected to begin in 2021 and extend until 2025.
