NASTT’s Horizontal Directional Drilling (HDD) Good Practices Guidelines – 4th Edition
This Horizontal Directional Drilling (HDD) Good Practices Guidelines, Fourth Edition is presented by the North American Society for Trenchless Technology (NASTT), a non-profit educational organization. The objective of this publication is to provide contractors, engineers, and utility owners with information that will assist with the completion of successful HDD installations. All NASTT publications are peer reviewed by volunteer industry professionals to ensure that they offer generic and non-commercial information. This Fourth Edition work was funded by NASTT as part of our educational outreach program. Since 1990, the all-volunteer members of NASTT have presented non-commercial information about green alternative engineering methods to North American communities. NASTT offers multiple, high quality courses each year throughout North America, covering various trenchless topics. For more information on our many educational opportunities, please visit nastt.org.
