Environmental Services is preparing to construct repairs to a public sewer mainline pipe in SW Washington Street between SW Park Avenue and SW 10th Avenue. This project will protect the public and the environment by reducing the possibility of sewage releases and basement flooding in buildings and streets.
The public sewer mainline to be repaired is in the north side of SW Washington Street between SW Park and SW 10th Avenue.
In general, work hours are from 7 a.m. to 6 p.m. Monday through Saturday while crews complete pre-construction activities. To reduce public impacts and complete the work as quickly as possible, the actual sewer repair work (to be scheduled in the near future) might be completed at night between 6 p.m. and 7 a.m. Monday through Saturday.
Between now and early November, crews will conduct pre-construction activities before they proceed with sewer repair work. These activities will include the following:
The temporary bypass system currently set up at the northwest corner of SW Washington Street and SW 10th Avenue is diverting stormwater flows from one mainline pipe to another pipe when it rains to help prevent basement flooding and sewer backups. It will remain in place while the city's contractor completes pre-construction activities and develops a plan to repair public sewer pipes.
The numerous paint markings on the pavement indicate the presence of underground utilities, such as communication cables, water lines, sewer pipes, gas lines, and power lines. To understand what each color means, see the graphic to the right.
This area of downtown Portland is currently busy with other construction projects not to be confused with this urgent sewer repair project:

Environmental Services coordinates with multiple agencies to schedule and complete construction, minimize disruptions, and help people get to where they are going. To avoid circling around construction to find parking, the City recommends you use SmartPark garages. For locations, visit www.portlandoregon.gov/smartpark.
