Downtown-Old Town Sewer Repairs

Updated November 9, 2017

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:


No construction will occur in the public right-of-way (streets and sidewalks) during the city's Holiday Moratorium from November 16, 2017, continuing through January 2, 2018.

Construction of main line sewer pipe repairs will resume as early as January 2018.

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  .
