Environmental Services will soon begin construction on a project in neighborhoods citywide to repair about 20,000 feet of sewer pipes that are deteriorating due to age. There will be construction at multiple sites in southwest, north, northeast and southeast Portland.
This project will protect public health and the environment by reducing the possibility of costly breaks, leaks, blockages and sewage releases to the streets.
The work at your location is tentatively scheduled for the week of January 20th and will consist of the following phases. The process will occur in stages over the next few months.
- Jet cleaning of the sewer main
- Video recording and inspection of the sewer main
- Repairs to the sewer main or manhole that are required prior to lining
- Cured-in-place pipe lining process
- Routing of lateral connection to sewer mains
- Lateral repair to the curb as needed
You will receive a notice from the city's construction contractor at your door prior to work beginning in your area. The notice for the lining process will include a date when the liner will be installed. There will be periods of inactivity during these phases.
The city’s contractor will make most of the repairs using cured-in-place pipe lining (CIPP) and open trench excavation. CIPP involves
inserting a flexible resin liner that adheres to the inside of the pipe. Hot water or steam circulated through the pipe hardens the liner and gives the pipe a new interior surface. Workers access the pipe from the surface through a manhole, which reduces the need for excavation and minimizes surface disruption. You may notice an odor during the pipe lining process but it will dissipate quickly. To help reduce odors, run water in all sinks and basins to fill P-traps and completely cover floor drains with a wet towel or a zip bag filled with water. The contractor will excavate trenches to replace lateral connections to homes, manholes and storm drains.

What to Expect During Construction
- Construction crews will do most of the sewer lining work through manholes in streets.
- Roads will be closed to through traffic, but local residents will have access from one direction. You 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.
- You may notice an odor during the pipe lining process but it will dissipate quickly.
- On-street parking in or near the work area will be prohibited during work hours.
- Equipment and materials may be stored on nearby streets overnight.
- A city construction inspector will be 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.
Typical work hours will be 7:00 a.m. to 6:00 p.m. Monday through Friday. The contractor can also choose to work on Saturdays if necessary.We will notify residents in advance of night work at some locations.
