Southeast Interceptor Sewer Repair

Button. Click to sign up for email updatesEnvironmental Services has nearly completed design work for an inner southeast Portland repair of a deep interceptor sewer line that is deteriorating due to age. The repairs will extend the life of the sewer and protect public health, water quality and the environment. The city built the large-diameter Southeast Interceptor in 1954. It runs parallel to the Willamette River under inner southeast neighborhoods at depths ranging from 30 to 54 feet.

Two segments of the Southeast Interceptor require repairs. For the project map, click here.

Schedule

The project's final design work will continue through late fall 2016. Construction is currently anticipated to begin in late spring 2017.

Design Update

Based on information collected about the condition of the Interceptor, the project team has selected a repair technology that can be completed from inside the sewer line and will not likely require digging trenches in the roadway. Accessing the sewer line through manholes will require temporary lane closures, which will require traffic control and construction signage. These lane closures may cause additional traffic congestion during construction work periods.

We Welcome Your Input

While construction is still months away, city outreach staff have visited businesses and neighbors near proposed construction sites to inform them well in advance about construction timelines, schedules and anticipated impacts. If you have not been contacted or have concerns about this project related to business operations, disability issues, medical or business deliveries, or other concerns, please contact us. We will continue to work with the community to minimize disruptions where possible.

For more information
