Calgary’s residents have surpassed the city’s recommended daily water usage, consuming 501 million litres on Wednesday, just slightly above the sustainable threshold of 500 million litres. This spike in consumption comes as the Bearspaw South Feeder Main, a crucial water supply line, is temporarily shut down for repairs. City officials have labelled any usage above the limit as entering the “risky red zone,” urging citizens to conserve water during this period of infrastructure maintenance.
Current Water Usage and Restrictions
The city has been grappling with increased water usage following a brief two-day period of compliance, where consumption fell below the recommended limit. The implementation of water restrictions began on March 9, when city crews halted operations on the feeder main after experiencing two significant failures within the last two years. Normally, this feeder main accounts for approximately 60 per cent of Calgary’s water supply, and its closure has necessitated reliance on the smaller Glenmore water treatment plant to meet the needs of the city and its neighbouring communities, including Airdrie, Chestermere, and the Tsuut’ina Nation.
The repairs entail addressing weakened sections of concrete along the Bearspaw South Feeder Main while simultaneously working on a comprehensive replacement project that aims to install a new steel pipe by the end of 2026.
City Officials Call for Conservation
In light of the increased water consumption, Michael Thompson, the general manager of infrastructure services, has reiterated the city’s plea for residents to be mindful of their water usage. During an update regarding the ongoing repairs, he emphasised, “We aim to save 25 litres of water per person each day.” He noted that common household activities, such as running a dishwasher or washing machine, consume substantial amounts of water. For example, a single dishwasher cycle uses around 28 litres, while a front-load washing machine consumes approximately 62 litres. Reducing these activities by even one cycle per day could help residents meet or exceed their daily conservation targets.
Thompson also provided updates on the repair progress, explaining that rebar reinforcement work has been completed, and concrete pouring has commenced. Additionally, backfilling the excavations around certain sections of the pipe is now underway. “Replacement of the valves at the Shaganappi pump station will be completed this weekend,” he stated, adding that refilling one section of the feeder main is expected to require about 5 million litres of water.
Upcoming Construction Plans
Construction efforts will intensify, with the final microtunneling shaft set to commence on March 24 at 16th Avenue and 44th Street. A designated construction area will be established in the parking lot on the south side of 16th Avenue, which will remain in place until completion in December. Residents should anticipate intermediate traffic disruptions related to this work.
The reinforcement initiatives, along with the ongoing water restrictions, are projected to last an additional two weeks before the feeder main can resume service. Concurrently, the broader project of replacing the entire Bearspaw South Feeder Main with a new steel pipe is slated for completion later this year.
Why it Matters
The current situation underscores the delicate balance between infrastructure maintenance and resource management in Calgary. As the city navigates necessary repairs to ensure long-term water reliability, the increased consumption and resultant restrictions highlight the critical importance of community cooperation in conservation efforts. With climate variability and population growth posing ongoing challenges, the ability to adapt and respond to such infrastructure demands is vital for ensuring a sustainable water future for all Calgarians.
