County to host meetings on North Mercer sewer project

Public meetings will be held on March 2 in Bellevue and March 10 in Mercer Island.

People seeking information about King County’s North Mercer Island/Enatai Sewer Project are invited to public meetings on March 2 and March 10.

King County employees will share proposed plans to update aging sewer infrastructure serving Bellevue and Mercer Island since the 1970s, and people will be able to ask questions and share input.

The March 2 meeting runs from 6-8:30 p.m. at the Mercer Slough Environmental Education Center at 1625 118th Ave. SE in Bellevue. The March 10 meeting runs from 6-8:30 p.m. at the Mercer Island Community Center, 8236 SE 24th St.

The North Mercer Island/Enatai Sewer Project is needed to protect public health and the environment, and to ensure community members continue to benefit from reliable wastewater service.

After extensive analysis that considered community needs and priorities, King County identified an alternative for the project will involve placing about 14,000 feet of underground sewer pipeline along an alignment from King County’s North Mercer Pump Station, located at 7631 SE 22nd Ave. on Mercer Island, to the Sweyolocken Pump Station, located at 3100 Bellevue Way SE in south Bellevue.

This alternative was selected as the best approach for limiting community and environmental impacts as well as reducing potential for project costs and risks.

Project design is scheduled to begin in 2016 and construction is expected to begin in 2019 with completion scheduled in 2022.
