Horizontal Drilling

Horizontal Directional Drilling (HDD) is not a new technology when it comes to the installation of pressure pipe systems for water distribution or sewage conveyance. Until recently, the installation process has typically been more expensive than traditional open-cut methods for the same length of installed pipe because it requires highly specialized drilling equipment to complete the installation.

Directional drilling can be a viable alternative to consider for pressure pipe installations in areas that typically require only traditional cut-cover installation techniques. In addition to expediting the project schedule, this construction technique can also minimize earth disturbance and traffic impacts, which may have positive benefits on project permitting.
