What Does New Installation Mean?

New installation in the context of trenchless technology refers to the laying of new pipelines either to upgrade an existing sewer or water supply system or for new service connections. Previously installing new pipelines meant digging up stretches of roads, sidewalks, backyards, gardens, and driveways. Now that advanced machines are available that can dig below the surface of the earth without disturbing the surface, new installations are no more a cause for disruption. Methods like Horizontal Directional Drilling (HDD), and Microtunneling are widely used for this purpose.


Trenchlesspedia Explains New Installation

New installations of pipeline by trenchless rehabilitation are quick and can be done from manholes or entry points, using methods like pipe bursting, CIPP, and sliplining. These methods are used to replace sections of damaged pipes. However; when a completely new installation has to be set up, trenchless construction utilizes methods that are non disruptive unlike open trenching methods. Exit and entry points are about the only excavations needed for these methods. After conducting site investigation, obtaining a geotechnical report, and getting the appropriate permissions, the route for the pipeline is established. HDD, HAB, MTBM, Pipe ramming, Pipe jacking, are some of the methods which are then utilized for laying the new pipeline along the proposed path.
