Calgary’s recent water consumption figures reveal a concerning trend as residents used 501 million litres on Wednesday, exceeding the city’s recommended sustainable limit by just over one million litres. This surge in water use comes while the Bearspaw South Feeder Main is temporarily offline for repairs, prompting city officials to label any usage above 500 million litres as entering the “risky red zone.” City leaders are calling for increased conservation efforts from residents as the situation develops.
Water Use Exceeds Sustainable Limits
The spike in water consumption follows a brief period where usage dipped below the 500 million-litre threshold. The current restrictions, implemented on March 9, coincide with necessary repairs to the feeder main, which typically accounts for approximately 60 per cent of Calgary’s water supply. The main has experienced two significant failures in the last two years, necessitating the ongoing repairs.
With the feeder main out of commission, the city is relying heavily on the Glenmore water treatment plant to meet the demands of Calgary and surrounding areas, including Airdrie, Chestermere, and the Tsuut’ina Nation. The urgency of the repairs has led city officials to appeal to residents for responsible water use during this critical period.
City Officials Issue Conservation Plea
Michael Thompson, the city’s General Manager of Infrastructure Services, has taken a proactive stance in addressing the increased water consumption, reiterating the importance of conservation. “We aim to save 25 litres of water per person each day,” Thompson stated during a recent update. He highlighted that simple changes, such as reducing the frequency of dishwasher and washing machine cycles, can significantly contribute to achieving this goal. For instance, one less cycle per day could easily surpass the daily conservation target.

Thompson provided updates on the ongoing repair efforts, noting that the rebar work to strengthen weakened sections of the feeder main has been completed. Concrete pouring and backfilling are currently underway, with the replacement of valves at the Shaganappi pump station expected to conclude this weekend. Additionally, the refilling process for one section of the feeder main will commence soon, utilising approximately five million litres of water.
Upcoming Construction Work and Timeline
Looking ahead, Thompson announced that construction on the final microtunnelling shaft at the intersection of 16th Avenue and 44th Street will begin on March 24. This construction site will be established in the parking lot on the south side of 16th Avenue and is anticipated to remain operational until December, potentially causing some traffic disruptions.
Both the reinforcement efforts and existing water restrictions are projected to continue for another two weeks, after which residents can expect the feeder main to be back in service. In parallel, the city is advancing with plans to replace the entire Bearspaw South Feeder Main with a new steel pipe, a project expected to reach completion by December 2026.
Why it Matters
The situation in Calgary highlights the delicate balance between urban water demand and infrastructure sustainability. With the ongoing repairs and reliance on a smaller treatment facility, the city’s ability to provide adequate water supply is being tested. As climate change continues to impact water availability, the behaviours of residents during this period of limited supply will play a crucial role in shaping Calgary’s water management strategies for the future. Encouraging conservation now is not just about meeting immediate needs; it’s about fostering a culture of sustainability that will benefit the community in the long run.
