Horizontal Directional Drilling (HDD) is a steerable trenchless method of installing underground pipelines, cables, and conduits in a prescribed bore path by using a surface-launched rig, with minimal environmental impact on the surrounding area, which has become an increasingly common practice in underground construction.  HDD has become a preferred method of installing utilities, especially in highly congested areas (by avoiding road closures and blocking off areas) or environmentally sensitive areas (by keeping those wetlands and other areas virtually undisturbed).
