Construction Begins on Second Phase of Calgary's Bearspaw Feeder Main Replacement
The City of Calgary has commenced Stage B of the Bearspaw South Feeder Main replacement project, a critical infrastructure upgrade aimed at replacing a 50-year-old water transmission line that has ruptured twice in recent years. Construction began in May 2026 at two locations along 34th Avenue N.W. in the Bowness community, specifically between 73rd and 89th Streets. Unlike the previous phase which utilized microtunneling, this stage employs an open-cut method to accelerate the process, with completion expected by late October 2026. The new steel pipeline is vital as it transports approximately 60% of the city's treated water. Mayor Jeromy Farkas has characterized the aging infrastructure as a ticking time bomb, prompting a $609-million budget adjustment to expedite repairs. Residents are advised to anticipate traffic detours, noise, and temporary parking restrictions during the construction period. The entire replacement project is scheduled for full operation by the end of 2026, addressing severe water restrictions previously imposed on Calgarians following the pipe bursts in 2024 and 2025.
