Project Overview

Environmental Services is designing a project to repair or replace up to 40,100 feet of public sewer pipes that are deteriorating due to age. That's equivalent to 7.6 miles, or the distance from Portland's Broadway Bridge to Vancouver, Washington. Work will occur in both the Hillsdale and the Multnomah neighborhoods of Southwest Portland.

The project will also install new manholes and storm drain inlets where needed, repair existing manholes and storm drain inlets, and replace some public sewer connections to private properties from the main line in the street to the curb. This investment in your neighborhood will ensure continued dependable sewer service and protect the public and our environment by reducing the possibility of sewage releases to homes, businesses, and streets.


Design will continue through 2018. A construction contractor will be selected in early 2019. Construction is anticipated to begin in the summer of 2019 and take a year and a half to complete.

Project Map

Below is the Hillsdale project boundary map. Note that this area will see several sewer repair and stormwater improvement projects over the next few years. Two other large-scale sewer repair projects adjacent to this Hillsdale project are identified on the map, including Council Crest-Homestead and South Portland-Burlingame projects. These projects are in the early stages of planning and webpages will be developed in early 2018.
