Downtown-Old Town Sewer Repairs

Updated September 6, 2017

Environmental Services continues to construct repairs on 100 to 140-year-old public sewer pipes in SW Yamhill and SW Morrison Streets 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.

Phase One of the SW Yamhill-Morrison Sewer Repair Project, completed in the spring of 2017, installed 3,200 feet (0.6 mile) of Cured-in-Place-Pipe Lining (CIPP) to repair mainline public sewer pipes. Phase Two, which will continue now through this fall and perhaps even in early 2018, will repair the public sewer pipes in areas that were identified as high risk, where crews were not able to safely bypass sewage flows from adjacent properties to repair the public sewer in the street this past spring. The three-week light rail closure wasn't enough time to complete that challenging work. Environmental Services is back in contact with those properties to discuss and plan repairs to take place this fall at the locations shown in the map below.

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 more information, visit

To avoid circling around construction to find parking, the City recommends you use SmartPark garages.
