PMC uses horizontal directional drilling (HDD) to install new pipelines or to remediate high-risk watercourse crossings.

HDD is a relatively low impact method of boring underneath the riverbed into the bedrock, to position the pipeline away from any potential exposure to the watercourse.

 

STEP 1: Bore a new path in the ground underneath the river

STEP 2: Thread the pipeline through the bored hole to the other side of the river

An HDD has the benefit of going underground without disturbing wildlife or the environment. This method is an industry best practice.
