Environmental Services is continuing 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. Three locations are within the Piedmont neighborhood on N Baldwin Street, N Lombard Street and N Kerby Avenue.
The work will include repairing or replacing the public sewer main, manholes, storm drains, and sewer service laterals to the curb. This project will protect public health and the environment by reducing the possibility of costly breaks, leaks, blockages and sewage releases to streets.
This work is not to be confused with the large-scale, neighborhood-wide Piedmont Sewer Repair Project, which is currently being designed by Engineering Services and will begin construction later in 2015.
The citywide 2014-2015 CIPP lining work has been delayed and is anticipated to begin spring 2015 at locations throughout the city. The CIPP lining schedule for the above three locations in the Piedmont neighborhood of North Portland is uncertain at this time. Neighbors and businesses will be notified in advance of the work. Open trench repair work on the public sewer main will occur before the cured-in-place-pipe lining installation. Keep in mind that schedules are always subject to changes due to weather, supply availability, or other issues in the field.
You will receive a notice from the city's construction contractor at your door prior to the work beginning on your block. The notice for the lining process will include a date that the liner will be installed.
The work on North Baldwin has been completed. The remaining locations at North Lombard and North Kirby are scheduled for this spring/summer and will consist of the following phases.
- Jet cleaning of the sewer main
- Video recording and inspection of the sewer main
- Repairs to the sewer main or manhole that are required before lining
- Cured-in-place pipe lining
- Routing of lateral connection to sewer mains
- Lateral repair to the curb as needed
- Restoration of pavement and other areas disturbed by construction
There may be periods of inactivity between 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.
- 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.
- 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.
