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 June 2, 2020
Environmental Services is constructing repairs for a public sewer service lateral in SW Washington Street between SW Park Avenue and SW 10th Avenue in downtown Portland. This service lateral connects an adjacent property to the mainline public sewer pipe that crews repaired earlier this year. Repairs will help prevent sewage backups into buildings and streets.
This project is part of the larger Downtown-Old Town Sewer Repair Program managed by Environmental Services to assess the condition of and repair the public sewer system serving Downtown and Old Town Portland. The program represents millions of dollars in investments. Ultimately, these improvements will extend the life cycle of downtown sewer infrastructure by more than 50 years.
The public sewer mainline repaired is in the north side of SW Washington Street between SW Park and SW 10th Avenue.
The sewer repair work that was scheduled for June 2 and June 3 has been postponed due to downtown worksite safety concerns. An update will be posted once work is rescheduled.
Crews will use the Cured-in-Place-Pipe Lining (CIPP) method to repair the lateral. This method does not involve digging in the street.
Vactor trucks will be in the area during the CIPP process to operate vacuum pumps necessary to clean the pipes before the lining process and to maintain sewer service during the lining. Vactor trucks generate noise and may be in place for several hours at a time.
This work will require temporary lane closures in the west lane of SW 10th Avenue and in the north lane of SW Washington Street.
The short-term parking spaces currently designated for customer pickups from downtown retailers will remain in place through construction.
Crews have successfully completed the following improvements for this project:
One additional lateral sewer connection remains to be repaired. The geometry of the existing lateral was not conducive to standard repair methods. Engineers studied the problem to determine a new construction method.
Environmental Services will work directly with adjacent properties throughout the course of the project. Community outreach staff will listen to your suggestions and respond to your concerns. We encourage you to:
In the event of a sewer backup or basement flooding, call the Maintenance hotline immediately at 503-823-1700. It is staffed all hours and all days, 24/7.
