Tabor-Powell Sewer Project

Environmental Services is designing four sewer repair projects that will replace and repair about 37,000 feet (a little over 7 miles) of aging public sewer pipe at over 60 locations in northeast and southeast Portland (see map below). The public sewer pipes in this project are from 60 to 104 years old, with most being over 90 years old. Repairing and replacing aging sewer pipes protect water quality, public health and the environment.

Environmental Services will begin construction in December 2015.

Proposed Night Work

Environmental Services has applied for a noise variance to allow open trench work at night at the locations indicated on the maps below. Night work is needed because of the high daytime traffic volumes along these streets. Normal construction hours are 7:00 a.m. to 6:00 p.m. Monday through Saturday. Work after 6:00 p.m. and before 7:00 a.m. and all hours on Sundays requires a noise variance. For more information, contact the Portland Noise Office at

Construction Method

The city’s contractor will use open trench excavation, which will involves the steps below. There may be periods of inactivity between the steps. For more information on construction methods go to

  • Cut pavement for pipe installation
  • Remove pavement and other materials
  • Install sewer pipe
  • Excavate and connect drains
  • Excavate and hook up sewer connections to homes and businesses
  • Backfill and compact trenches with sand or gravel
  • Install temporary pavement
  • Complete final paving and restoration

The equipment the contractor will use includes a pavement saw, track hoe, front-end loader, dump trucks, by pass pumps, pavement roller, generators and lights.
