Bearspaw South Feeder Main Improvements

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.

2024 repair

Short term repairs on the Bearspaw South Feeder Main were completed in 2024. The pipe has stabilized and is responding well to the 29 repairs.
