What is Pipe Rehabilitation?




Pipe rehabilitation is that phase of trenchless rehabilitation that undertakes the repair or replacement of sewer and water pipelines that run under a city or borough, connecting homes, offices and industries to the community sewer system or water connection. Trenchless technology facilitates restoration and replacement with little to no digging required. Pipe rehabilitation can ordinarily be carried out from utility holes. There are various methods for trenchless rehabilitation of pipes which are cost-effective, quick, reliable, and long-lasting.






Trenchless techniques are becoming popular because they are nondisruptive and eco-friendly.
Pipe rehabilitation methods include sliplining, cured-in-place pipe (CIPP), thermoformed pipe, mechanical spot repair and pipe bursting. The favored way of pipe rehabilitation is CIPP which involves the use of a soaked resin liner that is saved and inserted into the transformed pipeline after the pipeline is cleaned and inspected. Once placed within the pipe, the coating is expanded, using compressed air or steam, and allowed to fill the tube. Heat is applied to the liner to expedite the curing method. Another generally used trenchless method is pipe bursting in which a pipe, with a slightly smaller diameter than the host pipe, is inserted behind a bursting head. The packed head has a somewhat larger diameter than the host pipe and, as it rotates through the host pipe, it bursts the tube and pushes the broken pieces into the surrounding soil while pulling the new pipe behind it and replacing the damaged pipe. Mechanical spot repairs are used for strengthening small areas of damaged tubes that do not need to be returned.
