Northridge Feedermain Project

Project updates

Microtunneling will begin in early 2019 under Panamount Blvd N.W.

Microtunnel construction crossing Stoney Trail began October 30, 2018. This does not require road closures. Road access will be maintained to homes, the school and the community centre.

Construction Impacts

  • January 7 - June 2019: Westbound lanes of Panamount Blvd. 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 Blvd. N.W. and Panorama Hill N.W. has been closed. Flashing lights are being installed at the crosswalk on the west side of this intersection.
  • Eastbound Calgary Transit bus stop will be temporarily moved farther east.
  • Greenway pathway in Carrington from 14 St. NW to Centre St. N will be closed until further notice.
  • Speed limits will be reduced to 30 km per hour during construction.
  • Snow removal will be upgraded from a Priority 2 to Priority 1 route.
  • Construction noise, vibrations and dust are possible during the work hours of 7 a.m. – 7 p.m. Monday to Saturday.
  • Increased traffic to site (construction crews, trucks hauling materials to and from site).
  • To ensure safety, the work site will be fenced and access will be restricted to construction personnel only.

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 Blvd. N.W., Panamount Blvd. N.W., Harvest Hills Blvd. N.W. and then along the Transportation Utility Corridor to 140 Ave. 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 Blvd., north across Stoney Trail, east of 14 Street N.W.

How might the Northridge Feedermain construction impact you?

We are using microtunnelling technology. This technology helps to minimize construction impacts like disruptions to traffic and community access, dust and noise.

Construction will take place in two stages:

Stage One - Tunnelling (October 2018 - March 2019):

  • Tunnelling under Stoney Trail will not require road closures.
  • Tunneling under Panamount Blvd N.W. will require lane closures.

Stage Two - Open Trench (Spring 2019 - Summer 2020):

  • Open trench tender and construction of the remaining feedermain will start in spring 2019
  • Open trench excavation is the traditional and most common method of feedermain construction and consists of excavating down to the required depth, laying the pipe and then backfilling the trench.
