Bearspaw South Feeder Main incident

Background

The Bearspaw South Feeder Main is the largest in Calgary’s network, and distributes a significant portion of the city’s treated water supply. The feeder main experienced a break on June 5, 2024.

Since then, 29 pipe segment repairs have taken place to support the stabilization of feeder main and the pipe has undergone an investigation to gain an understanding of the conditions that lead to the failure. The Bearspaw South Feeder Main will be undergoing further improvements to support long-term resiliency. The project will add a parallel pipe of the same size as the existing BSFM. Over time, this new pipe will take over service from the current line. Learn more on the Improvements Project page.
