Choosing the Right Trenchless Sewer Rehab Method

Posted by Olivia Singer on Sep 24, 2020 12:58:29 PM

Trenchless sewer rehabilitation offers wastewater professionals a less invasive method for repairing damaged or deteriorating parts of our underground infrastructure. Before trenchless rehab methods were introduced, wastewater professionals relied on dig-and-replace, which required excavation along the full length of the defective pipe to remove and replace it completely. This was not only disruptive, but also costly and precarious work. thumbnail_1200

Instead, trenchless technologies offer a way to restore the existing pipe’s structural integrity without ever taking it out of the ground. 

Over time, more and more methods of trenchless rehab have been introduced, including cured-in-place pipe (CIPP), sliplining, pipe bursting and mechanical spot repair. While each method aims to achieve the same goal, some are more practical for certain types of jobs than others. The method chosen may be determined by the resources available to the crew—including equipment, time and money, the location of the pipe, or the severity of the damage, among other factors. 

To ensure the most impactful, yet resource-conscious, method is selected, crews should consider their options for the job at-hand.
