Calgary’s recent water consumption has raised concerns, as residents used 501 million litres on Wednesday, exceeding the city’s sustainable benchmark of 500 million litres. This spike comes during the shutdown of the Bearspaw South Feeder Main for essential repairs, a situation prompting city officials to urge residents to limit their water usage. The city has designated any water use over the recommended limit as part of the “risky red zone,” underscoring the need for conservation.
Current Water Usage Patterns
Following two days of water consumption below the recommended threshold, the latest figures highlight a troubling trend. The Bearspaw South Feeder Main, which typically provides about 60 per cent of Calgary’s water supply, has been offline since March 9 due to urgent repairs necessitated by consecutive failures in the last two years. As a result, the city is relying heavily on the smaller Glenmore water treatment plant to meet the needs of Calgary and neighbouring communities, such as Airdrie and Chestermere.
The repairs involve addressing multiple weakened sections of concrete along the feeder main, with parallel efforts underway to replace the entire system with a new steel pipe expected to be operational by the end of 2026.
City Officials Call for Conservation
The city’s general manager of infrastructure services, Michael Thompson, has made a renewed appeal for residents to conserve water. “Our goal is to save an average of 25 litres of water per person each day,” Thompson stated during a recent update. He pointed out that household appliances significantly impact water usage; for instance, a dishwasher consumes approximately 28 litres per cycle, and a front-loading washing machine uses about 62 litres. “Cutting back just one cycle a day can help reach or even surpass your daily target,” he added.
Thompson also provided updates on the repair work, noting that the rebar reinforcement of the feeder main has been completed and concrete pouring is now in progress. The city plans to refill one section of the feeder main, which will require an additional 5 million litres of water.
Upcoming Construction and Traffic Impacts
Construction is set to ramp up further, with the final microtunneling shaft for the Bearspaw South Feeder Main beginning on March 24 at 16th Avenue and 44th Street. Citizens can expect a designated work area in the parking lot on the south side of 16th Avenue, which will remain in place until the work concludes in December. Thompson has also warned of intermediate traffic disruptions resulting from this construction.
The ongoing reinforcement measures, coupled with water restrictions, are expected to last approximately two more weeks before the feeder main can be reactivated. Meanwhile, the full replacement of the feeder main is projected to be completed by December.
Why it Matters
The situation in Calgary serves as a crucial reminder of the delicate balance between infrastructure reliability and environmental resource management. As the city grapples with water supply challenges, the call for conservation highlights not only the immediate need to safeguard water resources but also the long-term implications of infrastructure investment and environmental stewardship. The collaboration between residents and city officials in conserving water during this critical period will play a vital role in ensuring a sustainable and resilient water supply for Calgary’s future.
