The City of Portland’s Bureau of Environmental Services is continuing our work to repair and replace critical sewer and stormwater infrastructure. Environmental Services will continue to provide information and updates on construction schedules and activities during the COVID-19 emergency.

Updated May 13, 2020

The NW Northrup and 22nd Sewer Repair Project continues construction to repair nearly 1000 feet of 130-year-old public sewer pipe under NW Northrup St between NW 21st and NW 23rd avenues. Multiple tree roots have grown into the pipe causing it to deteriorate. Repairing the sewer will reduce the possibility of costly breaks, sink holes and sewage releases to homes, businesses and streets.

General Schedule

Construction is expected to be complete by July 2020.

Evening, Night, and Weekend Work

While most construction will occur from 7:00 a.m. to 6:00 p.m., Monday through Friday, the Portland Noise Office has granted the project a noise variance to work in the evening and overnight due to high traffic volumes and Portland Streetcar operations.

Construction Method

Crews will primarily use a trenchless construction method called Cured-in-Place Pipe-Lining (CIPP). CIPP requires little to no digging and significantly less time to complete than other sewer repair methods. To learn more about sewer construction methods go to: www.portlandoregon.gov/bes/methods. 

What to Expect During Construction

• Noise, Vibration, and Dust could disrupt normal neighborhood activity.  
• Traffic Delays are expected in and near the work area.   
• Driveway Access may be temporarily blocked when crews are working in front of your house or business.  
• No Parking or little parking will be allowed in and near work zones, especially during work hours.   
• Equipment Storage will occur in the work zone and on nearby streets overnight.   
• Sewer, Water, and other utilities are expected to remain in service during construction.
