Community information about area construction impacts and replacing, reinforcing and rehabilitating the Bearspaw South Feeder Main.

Helping our community navigate construction

To protect Calgary’s drinking water system and ensure it continues to serve the city reliably into the future, we are reinforcing and replacing the Bearspaw South Feeder Main (BSFM). 

We know that construction has been disruptive and will continue to impact daily life for residents and businesses in the area. This page is here to support you by bringing together clear, up‑to‑date information about construction and related activities from Bearspaw South Feeder Main. Our goal is to help you easily find the information you need, stay informed about what’s happening nearby, and remain connected to your community throughout the project.

Community mitigation

Several mitigation measures are in place to help protect communities in the event of a feeder main failure. 

These include flood barrier adjustments along the Bow River, temporary pathway barriers with a ramp to maintain access, a staging area at Shouldice Athletic Park for pumps and equipment, and ongoing maintenance of catch basins. 

The City continues to evaluate additional mitigation options and will communicate updates as work progresses.

Measures in place to protect community

  • Two segments of the Bow River flood barrier along Montgomery Blvd. N.W. were removed so water can flow direct into the river. 
  • Temporary barriers have been installed along the Bow River pathway next to Parkdale Blvd. N.W.
  • A pathway ramp is being built over the barrier at Parkdale Blvd and 32nd Street N.W. to restore access to the Bow River Pathway.
    • A staging area is being set up in Shouldice Athletic Park to house pumps and equipment which can be quickly deployed if there is a release.
    • Outflows to the river have been opened and manhole covers replaced in several areas. 
  • We will continue to clear catch basins across the community.

Current road closures

The City of Calgary is taking precautionary measures around two segments of pipe that we are aware have an enhanced level of deterioration.  

A detour has been put in place around the location of the two segments to support risk mitigation. 

Traffic impacts

Traffic impacts due to the detour include: 

  • Westbound 16 Avenue N.W. exit ramp to Sarcee closed. 
  • Traffic will be detoured to 29 Avenue N.W. 

The detour will be in place until further notice. Updates will be provided as they become available.
