Tabor Sewer Project

Updated March 13, 2019

Environmental Services has almost completed repairing or replacing about 17,000 feet (over 3 miles) of deteriorating public sewer pipes in the Tabor neighborhood area that are between 60 and 104 years old. These repairs will help protect the public and the environment by reducing the possibility of costly breaks, leaks, blockages, and sewage releases to homes, businesses, and streets.

Construction Schedule

Please be aware that schedules are subject to change due to a variety of factors, such as conditions underground, weather, traffic impacts, and subcontractor and materials availability issues.

Crews will be returning to several previous work locations to complete miscellaneous outstanding items.

  • Crews will be completing finish work in multiple locations where CIPP lining has occurred. Some tasks may require closing the road to through access, but local access for those living and conducting business on the street will be maintained. 

  • Remaining outstanding items are expected to be complete by April 2019.

More about Trenchless Sewer Construction

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

CIPP Lining Work Project Schedule

The Tabor CIPP lining work began in spring 2018 and all repairs are expected to be complete in January 2019. 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. Residents near each location will be notified in advance of work.
