Since 1996, DTD has focused on the environmental applications of horizontal directional drilling (HDD). We have perfected the specialized techniques needed to install and develop wells for subsurface remediation and water resources development.

The Efficiency of HDD

Directional drilling and horizontal wells are often more efficient than other access methods and can replace a vertical well network by maximizing the zone of influence for remediation technologies. Horizontal wells also can be located beneath surface obstacles and can reduce disruption at a site.

The Nation's Leader

When engineering experts need to install remediation systems, solve water resources challenges, or build subsurface infrastructure, they turn to the experts in HDD -- Directed Technologies Drilling.
