Calgary officials say they have successfully connected the Bearspaw South feeder main to the city’s water distribution system, ending an emergency repair saga now estimated to approach $25 million.
After stabilizing the system, successfully completing final water quality tests, and refilling reservoirs, local officials say they are confident that typical water demand can now be met. As a result, all water restrictions were lifted on September 22.
“I’d like to thank each and every person who worked on this critical maintenance project, and helped ensure the safety and security of our water system,” announced Calgary Mayor Jyoti Gondek as water restrictions were lifted. “A special thank you to everyone who understood the importance of saving water and helped reduce pressure on our water system. My thoughts have especially been with the residents and businesses of Bowness and Montgomery.”
By the end of October, Calgary officials say they will receive a detailed forensic report from consultants that includes results from acoustic monitoring, as well as soil and structural analysis of the feeder main that burst on June 5.

Smaller sections of pipe are still set for repair in October and November along Memorial Drive in Parkdale, but aren’t expected to create significant impact, officials said.
Hydrant flushing continues to manage turbidity of the water, a normal process when a pipe is returned to service. As valves continue to open, it is likely that some people will notice that the water has a chlorine smell, which is temporary and will resolve quickly.
Calgary recently began the three-day process of filling the Bearspaw South Feeder Main with 22 million litres of water. The water used to refill the Bearspaw south feeder main came from the Bearspaw Water Treatment Plant, making it separate from what is coming from the rest of the city’s limited distribution system.
