Horizontal directional drilling is a means by which underground utilities are installed in both urban and rural areas. Drilling has a much smaller impact on grass, sidewalk, asphalt, and concrete on the surface than other utility installation methods such as trenching or plowing. A boring machine drills underneath the surface from a small entry pit up to a predetermined exit pit. From there, a conduit is attached to the drill head for pull back to the entry pit. With the utilization of a backreamer, one or several pipes can be pulled the length of the drill shot.
