About this project
King County is replacing the Fremont Siphon, a major sewer pipe running under the Ship Canal between Fremont and Queen Anne. The new siphon will be located west of the existing siphon to reduce project risks and impacts to the community. Construction has already begun and will continue until early 2017. The old siphon will be retained by King County for use by the Wastewater Treatment Division as necessary.
Why do we need this project?
The Fremont Siphon has provided safe, reliable sewer service to north Seattle – including the West Woodland neighborhood– and portions of north King County for decades. The existing Siphon is nearly 100 years old and has reached the end of its of service life. The new pipes will ensure north Seattle and northern King County continue to enjoy safe, reliable sewer service for decades.
