In a concerning turn of events, Calgary residents consumed 501 million litres of water on Wednesday, surpassing the city’s sustainable daily limit of 500 million litres while repairs to the Bearspaw South Feeder Main are in progress. This situation has prompted city officials to categorise any usage above the threshold as falling into the “risky red zone,” urging citizens to minimise their water consumption during this critical period.
Ongoing Repairs and Water Restrictions
Since March 9, water restrictions have been in place following the shutdown of the Bearspaw South Feeder Main, which typically serves as a vital source for approximately 60 per cent of Calgary’s water supply. This measure comes after two significant failures within the feeder main over the past two years necessitated urgent repairs to several vulnerable concrete sections. During this time, the city has shifted its reliance to the smaller Glenmore water treatment plant, which is also responsible for supplying water to neighbouring communities, including Airdrie, Chestermere, and the Tsuut’ina Nation.
Michael Thompson, Calgary’s general manager of infrastructure services, highlighted the importance of conservation during this challenging time. “We aim to save 25 litres of water per person per day,” he explained. Simple actions, such as reducing the frequency of dishwasher and washing machine cycles, can significantly contribute to achieving this goal.
Progress on Repairs
As repairs continue, Thompson confirmed that rebar reinforcement work on weakened sections of the feeder main has been completed, and concrete pouring is currently underway. Additionally, backfilling around specific sections of the pipe has begun. The replacement of valves at the Shaganappi pump station is expected to be completed this weekend, while plans to refill one section of the feeder main will require approximately 5 million litres of water.

Furthermore, the city is set to commence construction on the final microtunneling shaft at the intersection of 16th Avenue and 44th Street on March 24. This construction will create a temporary work zone in the adjacent parking lot, which is projected to remain in place until the project’s completion in December, causing intermittent traffic disruptions.
Looking Ahead
The repair work, along with the current water restrictions, is anticipated to continue for another two weeks before the feeder main is reinstated to service. Concurrently, the city is progressing with the comprehensive replacement of the entire Bearspaw South Feeder Main, which is expected to be finished by December 2026.
The urgency of these repairs cannot be overstated, as they are crucial for ensuring a reliable and safe water supply for Calgary and its surrounding areas.
Why it Matters
The ongoing situation highlights the delicate balance between urban water supply and environmental stewardship. As Calgary faces increased water consumption amidst repairs, the city’s call for conservation serves as a reminder of the collective responsibility residents have in safeguarding vital resources. With climate change intensifying pressures on water systems, it becomes even more critical for communities to adopt sustainable practices now, ensuring a resilient future for all.
