With the advent of new construction technologies comes the need for proven field tests to advance their use. Horizontal directional drilling (HDD) using ductile iron pipe, first introduced in 1994, is a method of installing the pipe underground without digging a trench. With HDD, a gentle arcing bore path is drilled horizontally beneath the surface, then the pipe is joined section by section above ground, and then pulled through.
