North/Northeast Portland Sewer Repair

As part of a large-scale, city-wide sewer repair program, Environmental Services is currently designing three sewer and stormwater repair projects in North and Northeast Portland neighborhoods. These projects will replace or repair approximately 91,000 feet of public sewer pipes that are on average 90 years old and deteriorating due to age. That is the equivalent of over 17 miles of sewer pipes.

The adjacent project areas will include construction in Piedmont, Humboldt, Woodlawn and King neighborhoods, plus a few blocks in Overlook and Arbor Lodge. The overall boundaries extend from Columbia Boulevard to the north, Campbell Avenue to the west, Going Street to the south, and 17th Avenue to the east. See map below.

Schedule

Design of the three projects will continue through 2015, with construction beginning fall 2015 in some areas and continuing for two years.  Environmental Services is closely coordinating these projects, since construction in any one of these neighborhoods may impact residents and businesses from adjacent neighborhoods. We appreciate your patience as we work to protect water quality, public health and the environment.

The Big Picture

In the early 1900s, when Portland was growing rapidly, the city built hundreds of miles of sewers. Since most sewer pipes have a lifespan of about 100 years, Portland is now facing an urgent need to modernize our aging sewer infrastructure. Of the 2,500 miles of sewer pipe that run under our city's streets, over one-third are more than 80 years old. To begin addressing this need, Environmental Services has launched a large-scale effort to repair or replace the highest priority pipes in our aging sewer system. This represents the second largest sewer program in the city's history, and
Piedmont, Humboldt, Woodlawn, and King are some of the neighborhoods that will benefit.

Projects to replace or repair aging sewers are important and have several benefits:

  • Prevent sewage releases into streets and homes
  • Protect public health, water quality and the environment
  • Reduce risks of street flooding
  • Cost less than fixing sewers after they break
