Calgary’s water consumption has surged, with residents using 501 million litres on Wednesday, surpassing the city’s advised limit of 500 million litres during the ongoing repairs of the Bearspaw South Feeder Main. This increase comes just days after two consecutive days of lower usage, pushing the city into what officials have termed the “risky red zone.” City leaders are urging residents to adopt conservation measures as the situation unfolds.
Current Water Restrictions and Their Implications
The latest round of water restrictions was initiated on March 9, coinciding with the shutdown of the Bearspaw South Feeder Main, which typically provides approximately 60 per cent of Calgary’s water supply. The feeder main has been out of commission due to multiple catastrophic failures over the past two years, necessitating significant repairs. During this downtime, the city has shifted its reliance to the smaller Glenmore water treatment plant, which also serves neighbouring communities like Airdrie, Chestermere, and Tsuut’ina Nation.
The repairs are critical, as they involve addressing weakened concrete sections of the feeder main while simultaneously preparing for the complete replacement of the existing infrastructure with a new steel pipe. This ambitious project is expected to be completed by the end of 2026.
Residents Urged to Conserve Water
Michael Thompson, the city’s general manager of infrastructure services, has renewed calls for water conservation following the alarming spike in usage. “We aim to save 25 litres of water per person each day,” Thompson stated during a recent update on the repairs. He highlighted how simple adjustments, such as reducing the number of dishwasher or washing machine cycles, can significantly contribute to meeting this goal.
As part of the ongoing repair efforts, rebar reinforcement work has been finalised, and concrete pours are currently underway. “Replacement of the valves at the Shaganappi pump station will be completed this weekend,” Thompson confirmed. The refilling of one section of the feeder main is set to commence soon, which will require an estimated 5 million litres of water.
Upcoming Construction Challenges
Construction on the final microtunneling shaft is scheduled to begin on March 24 at the intersection of 16th Avenue and 44th Street. A designated work area will be established in the parking lot on the south side of 16th Avenue, with the expectation that traffic disruptions will occur throughout the construction period, lasting until December.
The ongoing reinforcement and construction efforts are anticipated to continue for another two weeks, after which the feeder main should be ready to return to service. Concurrently, the comprehensive replacement project remains on track for completion by the end of the year.
Why it Matters
The current situation in Calgary serves as a crucial reminder of the delicate balance between urban infrastructure and environmental sustainability. As the city grapples with the challenges posed by its aging water supply system, the imperative for residents to conserve water cannot be overstated. In a time when climate change impacts are increasingly felt, responsible water usage is essential not only for individual households but for the community as a whole. The ongoing repair and replacement of critical infrastructure will determine not just the immediate future of Calgary’s water supply, but also its long-term resilience against environmental pressures.
