Trenchless Technology & Subsurface Construction

 

Chapter 8

 

Rehabilitation Methods

 

Once pipes are cleaned, inspected and prioritized, deficient pipes are rehabilitated. In the past, we dug trenches to rehabilitate and replace pipes. Not only did the excavation work take weeks to complete, but it also disrupted traffic and other utility services. Today, a couple of trenchless technologies provide new approaches to pipe replacement. Instead of spending time digging an open trench to remove and replace pipes, we use Cured in Place Pipe (CIPP) and Pipebursting, two fundamental rehabilitation technologies that are faster and minimize impacts to surrounding areas.
