Horizontal Directional Drilling

HDD is a steerable trenchless method of installing underground pipes, conduits and cables in a shallow arc along a prescribed bore path by using a surface launched drilling rig, with minimal impact on the surrounding area. Horizontal directional drilling is done with the help of a drilling fluid which is a mixture of water and usually, bentonite or polymer. The fluid is continuously pumped to the cutting head or drill bit to facilitate the removal of cuttings, stabilize the bore hole, cool the cutting head, and lubricate the passage of the product pipe. It is the spent fluid which becomes a liquid waste and must be disposed of in an environmentally safe fashion.
