Recent data reveals that Calgarians consumed 501 million litres of water on Wednesday, slightly exceeding the city’s sustainable threshold of 500 million litres. This spike in usage comes during a critical period when the Bearspaw South Feeder Main is out of commission for repairs, prompting officials to label any consumption above this limit as entering the “risky red zone.” City authorities are calling on residents to be mindful of their water usage as the city grapples with infrastructure challenges.
Water Supply Under Pressure
The ongoing repairs to the Bearspaw South Feeder Main, which typically provides around 60 per cent of Calgary’s water supply, began on March 9 following a series of significant failures in recent years. With this vital source offline, the city has shifted its reliance to the smaller Glenmore water treatment plant, which also serves neighbouring communities such as Airdrie, Chestermere, and the Tsuut’ina Nation.
The need for these repairs is pressing; the existing feeder main has undergone multiple failures and is currently being reinforced with rebar and concrete, while plans to completely replace it with a new steel pipe are underway. This extensive project aims for completion by the end of 2026.
Call for Conservation
In light of the elevated water usage, Michael Thompson, the city’s general manager of infrastructure services, reiterated the importance of conservation during an update on Thursday. He urged residents to aim for a reduction of 25 litres of water per person each day. “Dishwashers use around 28 litres a cycle, and a front-load washing machine consumes 62 litres, so skipping just one cycle can help meet or exceed your daily target,” Thompson advised.
With ongoing excavation and reinforcement work, Thompson also announced that valve replacements at the Shaganappi pump station would be finalised this weekend. The restoration process is expected to consume approximately 5 million litres of water, highlighting the challenges of managing resources during repairs.
Upcoming Construction Plans
Looking ahead, construction on the final microtunneling shaft at 16th Avenue and 44th Street is set to commence on March 24. A designated work area will be established in the parking lot on the south side of 16th Avenue and will remain in place until the project wraps up in December. Residents can expect some traffic disruptions during this period, underscoring the need for patience as these crucial upgrades take place.
The current reinforcement efforts are anticipated to last for another two weeks before the feeder main can be reactivated, with the complete replacement projected for late 2026.
Why it Matters
The situation in Calgary serves as a stark reminder of the delicate balance between urban infrastructure and environmental sustainability. As the city faces increasing pressures on its water supply, residents are called to action to conserve this vital resource. The long-term implications of these repairs and the necessity for efficient water management strategies will not only affect the immediate community but also set a precedent for how urban centres can navigate their growing demands while remaining environmentally conscious.
