2018 CIPP Lining - North & South Durham

Project Details

The City of Durham Department of Water Management is rehabilitating approximately 400,000 linear feet of aged sanitary sewer in certain northern and southern areas of the city. Cured-in-place pipe (CIPP) involves inserting a fabric tube saturated with polyester resins into the sewer main. Hot water or steam is then circulated through the tube to initiate the curing process. Upon cooling, the finished product will be a structurally sound, smooth, and water tight synthetic liner capable of extending the service life of the sewer by at least 50 years. Rehabilitating sewer mains by CIPP is typically much faster, less disruptive, and considerably less expensive than open cut excavations and repairs.

Water Management is working with two contractors on this project - Insituform Technologies in the north and AM-Liner East, Inc. in the south. Each contractor will be responsible for approximately 200,000 linear feet of CIPP installation. Beginning in mid-November, crews from these contractors will begin CCTVing and cleaning sewer mains, with installation to follow approximately one week later. Customers in work areas will be notified at least seven days in advance.
