What Is Trenchless Technology A no-dig technology that allows us to make trenchless installations of underground utility lines or to replace existing ones without large-scale excavation. The most popular applications include pipe for water, sanitary, storm and conduit for telecomunications or power cables. Who Uses It Contractors. Utility Companies. Public Works Departments. They are all turning to horizontal directional drilling (HDD) as their preferred method of installation or replacement. Reasons include cost-effectiveness, minimization of surface damage, low disruption to traffic or other activities, and environmental friendliness.
