As Calgary grapples with infrastructure challenges, recent data reveals that the city’s water consumption reached 501 million litres on Wednesday, surpassing the sustainable limit of 500 million litres. This uptick in usage comes at a critical time, as the Bearspaw South Feeder Main is currently down for essential repairs, prompting city officials to issue renewed calls for conservation.
Current Water Usage and Restrictions
The city’s water consumption has recently fluctuated, with two days of usage falling beneath the recommended threshold before surpassing it again. The Bearspaw South Feeder Main, which typically accounts for approximately 60 per cent of Calgary’s water supply, has been out of commission since March 9 due to a series of catastrophic failures over the past two years. As a result, the city is relying heavily on the smaller Glenmore water treatment plant to meet the needs of not only Calgarians but also surrounding communities such as Airdrie, Chestermere, and the Tsuut’ina Nation.
City officials have dubbed any usage above the sustainable limit as falling into the “risky red zone,” a term designed to encourage residents to limit their water consumption. Michael Thompson, the city’s general manager of infrastructure services, is leading the charge for conservation, reminding citizens of the importance of reducing their daily water usage.
Ongoing Repairs and Future Plans
The repairs on the Bearspaw South Feeder Main involve reinforcing weakened sections of the existing concrete infrastructure, a task that is being conducted alongside plans to replace the entire feeder main with a new steel pipe. This ambitious project is expected to be completed by the end of 2026.
Thompson provided an update on the repair process, noting that rebar work has been finalised, concrete pours are currently in progress, and backfilling around certain sections of the pipe has begun. This weekend, the replacement of valves at the Shaganappi pump station is set to be completed, with refilling of one section of the feeder main projected to use approximately 5 million litres of water.
“Starting on March 24th, we will be constructing the final microtunneling shaft on 16th Avenue at 44th Street,” Thompson added. This work will create a construction area that will remain in place until December, leading to some traffic disruptions.
The Call for Conservation
In light of the current situation, Thompson is urging residents to make a concerted effort to conserve water. “We aim to save 25 litres of water per person each day,” he explained. Simple actions, such as reducing the frequency of dishwasher and washing machine cycles, can significantly contribute to this target. A typical dishwasher uses around 28 litres per cycle, while a front-load washing machine consumes approximately 62 litres.
The enforcement of water restrictions is expected to last for at least another two weeks, until the feeder main can be reinstated.
Why it Matters
The ongoing repairs and the heightened water restrictions highlight the critical balance between infrastructure demands and environmental sustainability in Calgary. As the city navigates these challenges, the emphasis on conservation not only reflects a commitment to responsible resource management but also underscores the importance of community collaboration in overcoming infrastructure hurdles. In a time of increasing environmental awareness, Calgarians are called upon to play a pivotal role in ensuring a sustainable future for their water supply.
