Environmental Services is constructing in 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 spring of 2019. 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 July 12 – August 5:

SE 42nd Avenue Project Area

  • Installing manholes, catch basins, and laterals; and repairing the sewer pipe using open trench excavation on SE 42nd Avenue between Belmont and Washington Streets.

NW Mildred Street Project Area

  • Installing manholes, installing laterals, and repairing the sewer pipe using open trench excavation on NW Mildred Street between NW Maywood and Macleay Boulevard.

NW Glisan Street and 17th Avenue Project Areas

  • Constructing clean outs on NW Hoyt Street near 21st Avenue

Crews will also be repairing a few sewer pipes using cured-in-place pipe lining (CIPP). These repairs will occur at the following project areas:

  •  N Ivy and Fargo Streets and MLK Boulevard Project Areas
  • SW 64th Drive Project Area
  • SE 41st Avenue and Harrison Street Project Area
