King County Wastewater Treatment Division has scheduled an Open House & Information Sharing on the recently completed Fremont Siphon Replacement Project for Sunday, June 18th, from 11a – 3p.  Stop by, before or after your exploration of the Fremont Street Fair, to learn more about the new odor control facility and the incredible work done beneath the Ship Canal – all completed on-time!

On May 19th, major construction on the Fremont Siphon Replacement completed.  This replacement is a major achievement for our community, as it allows safe transport of sewage and storm water from North Seattle to the King County treatment plant in Magnolia.  The replacement is completed, and operational, all without accident or serious incident, and the construction will wrap an end to the interruptions and inconveniences suffered by neighbors of the Project.  A sigh of relief is expected for everyone involved!

King County has issued a big THANK YOU to Project neighbors, trail users and passers-by, for their patience with the disruptions that come with a major infrastructure construction project.  King County also expressed deep appreciation to community members who gave time and thought to working on ways to make the installation of new pipes and the odor control facility better for our neighborhood.

A few smaller details remain to be completed in the next weeks.  Some landscaping remains to be done, with plans for plants native to the Northwest Coast around the new facility.  Installation of rain gardens will also be completed, to capture and filter storm water on the site.  New public art and interpretive signs are also arriving soon, to brighten the building and educate visitors.

Time to celebrate the end of the Fremont Siphon Replacement Project.
