Environmental Services is constructing at various locations across the city to replace about 20,000 feet, or almost 4 miles, of sewer pipes that are in poor condition. These repairs will increase sewer system capacity, reduce basement backups, and protect water quality and the environment. 

Construction Scope and Schedule

There will be construction in several neighborhoods throughout Portland. At times, crews will work simultaneously in different neighborhoods. Environmental Services has started construction for this project, with plans to complete the work in the fall of 2018. Depending on the site and construction methods, work could last up to a month or more in your neighborhood. Residents will be notified before construction begins in each location.

Crew members will be making the following sewer repairs between November 1 – November 30:

SE Stark Street Project Area

  • Reconstructing a new lateral pipe, excavating an insertion pit, installing a manhole, and repairing the sewer mainline on SE Stark Street between 10th and 11th Avenues using pipe bursting. This will include day work and some night work.

NW Glisan Street and 17th Avenue Project Areas

  • Installing a clean out, reconstructing manholes, performing a spot repair, lining several lateral pipes and the sewer mainline using cured-in-place pipe lining (CIPP) on NW Glisan Street between 19th and 20th Avenues.
