What is a feedermain?

A feedermain is a large watermain that carries water from one reservoir or pumping station to another.

Why do we need the Northridge Feedermain?

Through development, the area of Keystone Hills continues to grow. The City has a responsibility to deliver safe, clean, reliable water to homes and businesses in this area.

Where will the Northridge Feedermain be located?

The Northridge feedermain starts at the Spy Hill North Pump station, along a route adjacent to Panorama Hills Boulevard N.W., Panamount Boulevard N.W., Harvest Hills Boulevard N.W. and then along the Transportation Utility Corridor to 140 Avenue. N.W. This feedermain will help to supply water to new northwest communities. The alignment extends from the south boundary of the Transportation Utility Corridor at Harvest Hills Boulevard., north across Stoney Trail, east of 14 Street N.W.

How might the Northridge Feedermain construction impact you?

Construction methodology includes a combination of microtunnelling and open trench. It will take place in two stages:

Stage 1 - Microtunnelling (Q3 2018 - Q2 2019):

  • Microtunnelling under Stoney Trail and a section of Panamount Boulevard N.W. is complete as of April 2019.
  • Feedermain installation will be complete at both sites by Q2 2019.

Construction impacts:

  • January 7 - June 2019: Westbound lanes of Panamount Boulevard at Panamount Hill N.W. have been closed. Eastbound lanes will accommodate two-way traffic.
  • The flashing light crosswalk on the east side of the intersection at Panamount Boulevard N.W. and Panorama Hill N.W. has been closed. Flashing lights are installed at the crosswalk on the west side of this intersection.
  • Eastbound Calgary Transit bus stop will be temporarily moved farther east.

Stage 2 - Open Trench (Q2 2019 - Q4 2020):

  • Open trench construction will start May 2019
  • Open trench excavation is the most common, and cost-effective, method of feedermain installation. Itconsists of excavating down to the required depth, laying the pipe and then backfilling the trench.

​​Construction impacts:

  • There will be temporary road closures and traffic detours along these routes during the open trench construction:
    • Westbound lanes of Panamount Boulevard from Panamount Hill N.W. to Harvest Hills Boulevard N.W.
    • Southbound lanes of Harvest Hills Boulevard N.W.
    • Northbound 14 Street N.W. near 140 Avenue
  • During school summer break, starting late June 2019, the Northbound lanes of Panaroma Hills Boulevard from Panamount Heights N.W. to Panamount Boulevard N.W. will be closed. Southbound lanes will accommodate two-way traffic.
  • The sidewalk along Southbound Harvest Hills Boulevard, and Westbound Panamount Boulevard will be closed during temporary road closures.
  • Potential water service interruptions are expected. Duration will be minimized as much as possible, and impacted customers will be notified ahead of any interruptions.
