Project update

September 26, 2018

Thank you to all the neighbors and interested community members who have made a phone call, sent an email, and/or attended a community meeting to discuss the North Mercer Island/Enatai Sewer Upgrade Project. Over the last year, the team has held 5 neighborhood walks for neighbors that live next to the future sewer pipeline, attended community events including Bike Everywhere Day and the Mercer Island Summer Celebration, and hosted an online open house to share project updates.

Watch for an invite to in-person and online open houses early next year.

If you or someone in your community would like to learn more about the project, please contact Kristine Cramer, Kristine.cramer@kingcounty.gov or 206-477-5415 to schedule a briefing.

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.
