Open house on the Fremont Siphon Replacement Project takes place March 26


Come to a workshop on Saturday, Jan. 12, and help King County design a wastewater facility site in Fremont that reflects community vision and values.


People are invited to an open house to get updates on design plans for King County’s Fremont Siphon Replacement Project.

The open house is set for Tuesday, March 26 from 5:30 to 7:30 p.m. at the Fremont Public Library, 731 N 35th St., Seattle.

At a workshop last January, King County sought community input on the design of a new facility that will be built in Fremont as part of a project to replace aging sewer lines beneath the Lake Washington Ship Canal.

Project staff will present two design options for the Fremont site and discuss how community input shaped concepts around landscaping, architecture and other site elements. People are invited to share their views on the new design options. Staff will also be available to answer questions and talk about other project-related plans and schedules.

The Fremont Siphon Replacement project is currently in design, with construction expected to start around mid-2014.

King County also operates the Ballard and Montlake Siphons, which run beneath the Ship Canal and convey wastewater from North Seattle to the West Point Treatment Plant in Discovery Park.

For additional information, or to arrange reasonable accommodations for people with disabilities at the open house, please contact Adair Muth at 206-263-7319 or 711 TTY Relay.

More information about the Fremont Siphon Replacement Project is available on the website.


Residents enjoy clean water and a healthy environment because of King County's wastewater treatment program. The county’s Wastewater Treatment Division protects public health, the environment and the economy by serving 17 cities, 17 local sewer districts and more than 1.5 million residents in King, Snohomish and Pierce counties. Formerly called Metro, the regional clean-water agency now operated by King County has been preventing water pollution for nearly 50 years.
