Trenchless construction methods

Certain sections of this feedermain are being installed using trenchless methods. Primary areas include:

  • Crowchild Trail.
  • The crossing of West Nose Creek.
  • A portion of 12 Mile Coulee Road. 

Trenchless technology is a method of installing pipe by constructing two vertical shafts and using a tunneling machine (or auger) to complete the crossing underground. This method of construction allows us to build infrastructure with minimal disruption to the surrounding area. 

This project employs several methods of trenchless technology. Each method was chosen to best address the conditions of the specific area and the potential impacts to be mitigated.

Trenchless methods are typically more costly than traditional open cut construction, but they are sometimes a better option to mitigate:

  • Significant disruptions to busy roads
  • Impacts on constructed or naturalized park areas
  • Impacts on wildlife and natural creeks in sensitive areas
  • The need to resurface infrastructure, such as roadway and other utilities
