2014 Cured-in-Place Sewer Repair Project

Environmental Services started work in 2014 on a project to repair about 20,000 feet of deteriorating sewer pipes at multiple sites in southwest, north, northeast and southeast Portland. The work includes repairing or replacing manholes, storm drains, and sewer service laterals that connect homes and businesses to public sewer pipes.

This project will protect public health and the environment by reducing the possibility of costly breaks, leaks, blockages and sewage releases to homes, businesses and streets. Construction began in fall 2014 and the project contractor completed main line sewer repairs in summer 2015. The contractor will return to some locations at a later date to repair lateral pipes that connect private properties to the main public sewer. Environmental Services will notify residents before construction begins in specific neighborhoods.

The city’s contractor is making most of the repairs using cured-in-place pipe lining (CIPP) and open trench excavation. Go to for more information about sewer construction methods.

What to Expect During Construction

  • Construction crews will do most of the sewer lining work through manholes in streets.
  • Typical work hours are 7:00 a.m. to 6:00 p.m. Monday through Friday.The contractor can also choose to work on Saturdays if necessary.
  • There will be night work at some locations. Environmental Services will notify residents in advance of night work.
  • Roads will be closed to through traffic, but local residents will have access from one direction. Residents may experience delays.
  • If work is right at your driveway and you have to use your vehicle, you will need to move it before the work starts.
  • Preparation and restoration will take a couple of days to complete but the pipe lining process should only take one day at each location.
  • Residents may notice an odor during the pipe lining process but it will dissipate quickly.
  • The contractor will excavate trenches to replace lateral connections to the curb or right-of-way.
  • On-street parking in or near the work area is prohibited during work hours.
  • Equipment and materials may be stored on nearby streets overnight.
  • A city construction inspector is on-site during work hours, and may be able to assist you with construction concerns. Inspectors typically wear a green City of Portland safety vest and hard hat.

Let us know if you have concerns such as business operations, disability issues or medical deliveries.
