SW Alder-Oak-Taylor Sewer Repair Project

Updated June 29, 2018Button. Click to sign up for email updates

Environmental Services continues construction to repair or replace about 800 feet of public sewer pipes in downtown Portland that are 100 to 140 years old and in deteriorating condition. The sewer pipes are showing signs of cracks, breaks, holes, offset pipe connections, and obstructions, putting the pipes at risk of structural failure. Urgent repairs at three locations shown on the map below will protect the public and the environment by reducing the possibility of sewage releases to buildings and streets.

Location

Repairs will be made in three locations (see map).

Project map

Schedule

Construction has been completed at two of the three locations:

  • SW Oak Street between SW 1st and 2nd
  • SW Alder Street between SW 2nd and 3rd

Construction continues at the third location:

  • SW Taylor Street between SW 6th and Broadway – The last portion of pipe lining will occur on a service lateral pipe sometime between July and September 2018. The schedule is dependent upon subcontractor schedules, availability of materials, and other factors.

Please note that construction schedules are also weather-dependent. Rain causes increased stormwater in the pipes, which makes it more difficult or impossible to bypass the combined sewage and stormwater flows in order to repair the pipes.

Work Hours

Regular work hours will be 7 a.m. to 6 p.m. Monday through Friday, and Saturdays as needed. The Portland Noise Office granted Environmental Services a Noise Variance to enable the city’s contractors to work at night to complete the pipe lining sewer repair work. Each of the three locations will require up to three nights of work.

Construction Methods and Traffic Impacts

A combination of Cured-in-Place-Pipe Lining and Open Trench Excavation construction methods will be used on this project. Traffic controls will be necessary in the work zones and will create delays. For details on the construction methods and traffic impacts, see the Project Overview.
