Calgary is facing a significant challenge as water usage surpassed the city’s sustainable limit of 500 million litres on Wednesday, hitting 501 million litres. This spike comes during ongoing repairs to the Bearspaw South Feeder Main, which is currently offline, prompting city officials to label excessive consumption as entering “the risky red zone.” Citizens are being called upon to reduce their water usage to alleviate pressure on the city’s water supply system.
Water Usage Exceeds Recommended Limits
The recent increase in water consumption follows a brief period of lower usage, where residents managed to stay within the recommended threshold of 500 million litres. The city has been implementing water restrictions since March 9, after the feeder main, responsible for about 60 per cent of Calgary’s water supply, was shut down due to serious structural failures. As repairs progress, the city is relying on the smaller Glenmore water treatment plant to meet the needs of Calgary and its neighbouring communities, including Airdrie, Chestermere, and Tsuut’ina Nation.
Ongoing Repairs and Infrastructure Upgrades
Michael Thompson, the city’s general manager of infrastructure services, has urged Calgarians to conserve water, especially as work continues on the feeder main. “We aim to save 25 litres of water per person each day,” Thompson stated, highlighting that even minor reductions in household appliance use can contribute significantly to this goal. For instance, skipping just one cycle of a dishwasher or washing machine can meet or exceed the daily target.
Thompson provided updates on the repair progress, noting that rebar work to reinforce weakened sections of the feeder main is complete and that concrete pours are currently underway. Additionally, the replacement of valves at the Shaganappi pump station is expected to finish this weekend, with plans to refill one section of the feeder main, which will consume approximately 5 million litres of water.
Future Construction Plans
Construction on the final microtunnelling shaft at 16th Avenue and 44th Street is set to commence on March 24, with preparations already in motion for the worksite. This construction will likely affect traffic in the area until its anticipated completion in December. The combination of these repairs and water restrictions is projected to last for another two weeks before the feeder main can be reinstated into service.
In parallel to these immediate repairs, the city is also moving forward with plans to replace the entire Bearspaw South Feeder Main with a new steel pipe, a project expected to reach completion by late 2026.
Why it Matters
The current situation underscores the delicate balance Calgary must maintain in managing its water resources, particularly in light of infrastructure vulnerabilities. As the community grapples with necessary repairs and heightened water usage, the collective effort to conserve water is crucial. The ongoing projects not only aim to restore a reliable water supply but also highlight the importance of sustainable practices among residents, reinforcing the need for proactive measures in the face of climate challenges and urban demands.
