Environmental Services is repairing about 40,000 feet (7.5 miles) of public sewer lines in your neighborhood that are between 60 and 100 years old and failing due to age. The project will protect the public and the environment by reducing the possibility of sewage releases to homes, businesses and streets.
Current Construction Activities
Four construction crews are working on sewer and lateral pipe repairs in the area. Please be aware that construction schedules are subject to change due to conditions underground, weather, traffic, subcontractor schedules and availability of materials. You will notice several phases as different equipment or specialized crews are required at each site.
Sewer repairs underway:
Cured-in-place-pipe lining is happening on blocks throughout the project area for the next couple of weeks and will be scheduled again throughout the project. Residents will receive a doorhanger with the exact date of activities nearest them, and any special instructions. Go to www.portlandoregon.gov/bes/article/467513 for more details on cured-in-place pipe lining.
Restoration activities and preparation for paving of disturbed areas is dependent on weather. Note: Where pipe spot repairs have been completed, temporary asphalt patches are left in place. Final restoration of the disturbed areas is scheduled as weather permits.
Other activities in the field:
What to Expect During Construction
The city will use a combination of open trench construction and cured-in-place-pipe lining (CIPP). The contractor may use more than one construction method in some areas. For example, the contractor may use CIPP on the main public sewer pipe and open trench construction to repair or replace laterals that connect private sewers from the curb to the public sewer in the street.
There are several phases of open trench construction:
Cured-in-place-pipe lining (CIPP) doesn’t require digging a trench. Work crews access the sewer from manholes to insert a flexible liner inside the old pipe. Hot water or steam inflates and cures the liner, which gradually hardens to form a rigid, smooth surface that seals cracks and restores the pipe to near-new condition. People who live and work near a CIPP repair project sometimes smell a chemical odor during the pipe-lining work. The odor is from the chemical styrene, which is in the resin liner installed inside the pipe. The odor dissipates quickly once the installation process is complete. The amount of airborne styrene produced is not a human health risk. Get more information about CIPP construction.
