Calgary’s water consumption has surged to 501 million litres in a single day, surpassing the city’s sustainable target of 500 million litres. This uptick comes during a crucial period when the Bearspaw South Feeder Main is undergoing essential repairs, raising concerns among city officials about the implications of excessive water usage.
Current Water Use Situation
The recent spike in water consumption follows a brief respite, where usage dipped below the recommended limit for two consecutive days. City officials have designated any usage above 500 million litres as entering the “risky red zone,” urging residents to exercise caution and conserve water. This new push for conservation is particularly important as the feeder main, which typically delivers around 60 per cent of Calgary’s water supply, has been offline since March 9 due to significant infrastructure issues.
During the downtime of the feeder main, the Glenmore water treatment plant has taken on the role of the primary water source for Calgary, as well as neighbouring areas including Airdrie, Chestermere, and the Tsuut’ina Nation. The situation has prompted city officials to actively engage with the public to promote water-saving practices.
Repair Work Underway
The infrastructure repair project aims to address several compromised sections of the Bearspaw South Feeder Main, which has faced two catastrophic failures in under two years. Michael Thompson, Calgary’s general manager of infrastructure services, confirmed that rebar reinforcement work is progressing well. He noted that concrete pouring is currently in progress, with backfilling around certain pipe sections also beginning.
“The replacement of valves at the Shaganappi pump station is set to be completed this weekend,” Thompson stated. He also mentioned that the refilling of one section of the feeder main will commence, which is expected to utilise approximately 5 million litres of water.
Thompson further advised residents on practical ways to conserve water, suggesting that reducing the use of dishwashers and washing machines can significantly impact daily water consumption. “We aim to save 25 litres of water per person each day,” he added, noting that even skipping one cycle of a dishwasher or washing machine can help achieve this goal.
Upcoming Construction and Traffic Impacts
In addition to the ongoing repairs, construction will begin on March 24 for a final microtunneling shaft located at 16th Avenue and 44th Street. This work area will be established in the parking lot on the south side of 16th Avenue and is expected to remain in place until completion in December. Residents should be prepared for intermittent traffic disruptions as the construction progresses.
The current reinforcement efforts, combined with the implementation of water restrictions, are anticipated to last approximately two more weeks before the feeder main can resume service. Concurrently, the larger-scale project to entirely replace the Bearspaw South Feeder Main with a new steel pipe is slated for completion by December.
Why it Matters
The situation in Calgary reflects the critical balance between maintaining essential infrastructure and managing natural resources sustainably. As the city grapples with its water supply challenges, the need for community cooperation in conservation efforts becomes increasingly urgent. High water usage not only strains the existing systems but also poses long-term risks to Calgary’s water sustainability, especially in light of the ongoing climate challenges that threaten water availability across Western Canada. The proactive measures taken by city officials, alongside public engagement, underscore the importance of preserving our water resources for future generations.
