Item Horizontal Directional Drilling(Trenton, N.J. : Department of Environmental Protection, Division of Science and Research, 2021-10) New Jersey. Department of Environmental Protection. Science Advisory Board. Water Quality & Quantity Standing CommitteeHorizontal directional drilling (HDD) is a trenchless construction process for drilling boreholes and installing pipe without disturbing the surface and area under which the pipeline is needed. HDDs are often used to cross sensitive areas or difficult to construct areas that involve, for example, roads, wetlands, and waterbodies (CenterPoint Energy, 2013). This methodology has distinct advantages in not disturbing surface conditions. However, as is the case with any type of construction, the HDD process requires developing a sound plan that includes contingencies for any potential problem encountered and an approach for preventing long-term environmental impact.
