Downtown-Old Town Sewer Repairs

Updated April 23, 2018

Environmental Services continues to design and construct repairs on 100 to 140-year-old public sewer pipes in downtown Portland that are in deteriorating condition. Repairs will protect the public and the environment by reducing the possibility of sewage releases to buildings and streets.


Construction and pre-construction activities are currently in process on two urgent repair projects:

A third downtown sewer repair project is being designed:


Construction on SW Alder-Oak-Taylor and on SW Yamhill-Morrison projects has resumed and may continue through May 2018. The Noise Office granted Environmental Services a noise variance for each project to enable the city's contractors to work at night to complete these urgent sewer repairs. Some daytime work will be necessary before and after pipe lining at each location.

The SW Caruthers-Mill project is currently accepting public comments on the city's proposal to work both days and nights to complete important public sewer repairs scheduled to begin construction in the fall of 2018. See the project webpage for details.

Get Portland MovingDowntown Open for Business

Throughout 2017 and into 2018, the Central Business District will be the site of multiple projects to repair and replace aging sewers, rail lines, bridge structures, streets, and other infrastructure. Projects with long-term benefits will cause short-term disruptions to residents, businesses and visitors. Environmental Services is coordinating with multiple agencies to schedule and complete construction, minimize disruptions, and help people get to where they are going. For information about other projects that will affect travel in and around the Central Business District, visit  

To avoid circling around construction to find parking, please use SmartPark garages; those near our work zones are shown on the project maps.
