Woodlawn-King Alleys Sewer Repair Project Update

Construction Begins Soon


  • Week of April 17 – crews will begin in the Williams/Cleveland alley between Highland and Holman
  • Week of April 24 – crews will begin in the Williams/Cleveland alley between Ainsworth and Jarrett
  • In three or more weeks – crews will begin in the Williams/Cleveland alley between Jarrett and Killingsworth


Work will progress in the following way:

  • The city contractor will bring materials and machinery to the work zone and store them in a centralized staging area in the right-of-way.
  • Tree trimming will be performed as needed to make room for large equipment, reduce the possibility of damage to trees, and help ensure public safety.
  • Video inspection crews will flush sewer with water to clear debris and then insert a video camera to document pipe and branch connection conditions.
  • Perform spot repairs to the main line sewer pipe. This involves excavating small trench sections to access the pipe.
  • Replace lateral connections between the main line sewer pipe and individual properties.
  • Install cleanouts with a vactor truck to clear a small diameter hole that allows crews to cut into the service lateral, connect a standing pipe to the surface, and add a cap at ground level. Cleanouts provide access for maintenance and repair of lateral connections.

Residents and businesses should expect periods of inactivity between each phase ranging from a few days to a few weeks. The duration depends on a variety of variables including underground conditions, weather, traffic impacts, subcontractor schedules, quality control tests and availability of materials. To learn more about What to Expect During Construction go to www.portlandoregon.gov/bes/article/632833.



Construction will move from one site to another as work phases are completed, with periods of inactivity between phases. Please be aware that schedules are subject to change due to a variety of factors, including conditions underground, weather, traffic impacts and subcontractor and materials availability.


The city will use a combination of open trench construction and Cured-in-Place-Pipe-lining (CIPP). Details about each construction method are available at www.portlandoregon.gov/bes/methods.


Construction hours are from 7:00 a.m. to 6:00 p.m. Monday throughFriday, but the contractor may schedule work during the same hours on Saturdays. The Portland Noise Office approved night work for two locations within the project boundaries. Homes and businesses near these locations will receive a separate notification before night work takes place.
