HDD: The Right Choice for Pasco County’s Pipe Installation

Pasco County Utilities has made headlines in the waterworks industry as a pioneer in the application of horizontal directional drilling (HDD). HDD is a technique in which pipe joints are assembled above ground and then pulled through a hole drilled under natural and manmade obstacles. HDD allows for environmentally friendly pipe installations under wetlands, rivers, creeks, highways, railroad tracks, buildings and other obstacles.

Study Shows Trenchless Technology Suitable for Longer Pipe Installations

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.

Mississippi Pipeline Boasts Longest Installation of 36″ Ductile Iron Pipe

Sixty feet below the surface of Sowashee Creek in east Mississippi lies a new section of pipeline — 1,640 feet of 36-inch AMERICAN ductile iron pipe — installed with little more than a ripple’s impact on the waterway. This section of pipeline marks the longest length of this size ductile iron pipe ever installed using horizontal directional drilling (HDD), a trenchless method of pipe installation that minimizes surface disturbance.
