Downtown-Old Town Sewer Repairs

Updated October 17, 2019

Environmental Services continues to design and construct repairs for 100 to 150-year-old public sewer pipes in downtown Portland that are in deteriorating condition. This work will identify and assess defects in public sewer pipes, manholes, and storm drain inlets. Evaluation of the identified defects will then be used to prioritize the repairs needed throughout the Downtown-Old Town area. Repairs completed through these public infrastructure projects will help reduce the possibility of sewage releases to buildings and streets.

The sewer repairs will be completed by a variety of contractors and will be supervised by Environmental Services engineers.

The Central Business District is 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.
