The first phase of the Glenmore Dam Infrastructure Improvements Program is the Utilities Relocation Project. This involves moving the water and gas utility lines currently running across the top of the dam to a tunnel underneath the Elbow River. Construction should be complete in Spring 2017.

Construction impacts

Before tunnelling can begin, shafts must be excavated on either side of the river. Construction impacts will include:

  • Increased traffic to site (construction crews, trucks hauling materials to and from site)
  • Construction noise from excavation of shafts
  • Possible vibration as the shafts/tunnels are excavated
  • A section of the off-leash dog park will be closed to the public
  • The pedestrian pathway across the dam will remain open for the duration of this project.
  • There will be a pathway detour on the north side of the dam

Updates

March 7, 2017

  • All tunnelling is now complete, including the line under the Elbow River.
  • We are in the final stages of installing the new water pipe and gas line in the tunnels, as well as the tie-ins to the existing utilities.
  • We are currently on track and expect to be complete in late April 2017. Removal of the existing lines on the bridge deck will follow in Phase 2 of this project.

What is trenchless tunnelling?

Micro-tunnelling is used to dig underground - or in this case under the river - using special equipment.To get equipment in place to dig the tunnel, a shaft is excavated on either end. Trenchless tunnelling is far less invasive than a traditional trench, and has several benefits:

  • Low to no impact to the river
  • Tunnelling work is kept underground
  • Limited amount of dust, only at launch and retrieval shafts
  • Removal of material is limited to the shafts and tunnel, rather than a full open trench
