Environmental Services is continuing construction on the Tabor Sewer Repair Project in your neighborhood. This project will replace and repair aging public sewer pipe ranging from 60 to 104 years old. Repairing and replacing aging sewer pipes protects water quality, public health and the environment.
Sewer construction to date has focused on replacing and repairing sewer pipes using methods involving excavation. Environmental Services is now preparing for additional sewer repairs in your neighborhood in 2018, which will mainly use a construction method called Cured-in-Place Pipe-Lining (CIPP).
CIPP lining is a trenchless method that requires little or no digging and significantly less time to complete. Work crews access the sewer from manholes to insert a flexible liner inside the old pipe. The liner is inflated with air and exposed to ultraviolet light (UV) to gradually cure and harden the liner. As the liner hardens, it forms a rigid, smooth surface that seals cracks and restores the pipe to near-new condition. For more details about CIPP, visit www.portlandoregon.gov/bes/pipelining.
The Tabor CIPP lining work began in Spring and all repairs are expected to be complete by Winter 2018. Work in most locations is expected to take one to two days. More time may be required where spot repairs are needed or additional work is identified.
CIPP lining is highly weather dependent. For this reason, the contractor has been given a large window to complete lining repairs in your neighborhood. CIPP lining activity will be low during wet months and increase during dry months. Residents near each location will be notified in advance of work.
