Powell Sewer Project

Button. Click to sign up for email updatesUpdated February 15, 2018

Environmental Services is continuing construction on the Powell 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.


Below is a map showing locations of upcoming construction through February 28, 2018. 

The estimated construction schedule is subject to change due to a variety of factors including conditions underground, weather, traffic impacts, subcontractor schedules and availability of materials.

Our contractor will apply temporary pavement after completing pipe installation in all work areas. Paving will be scheduled during dry weather and our contractor will take advantage of openings in paving crew schedules to complete work as timely as possible. Paving may begin on short notice, and street closures may last for up to a week where concrete is poured.

Progress Map

Additional Trenchless Sewer Construction Coming in 2018

The current project is expected to be complete in January 2018 and 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). The map below shows the location of 2018 CIPP repairs in your neighborhood. 

Powell CIPP Locations

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

2018 CIPP Lining Work Schedule

The Powell CIPP lining work is scheduled to begin in January 2018 and all repairs are expected to be complete by November 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.
