Calgary residents have drawn attention to their water consumption after using 501 million litres on Wednesday, surpassing the city’s recommended sustainable limit of 500 million litres. This spike in usage is particularly concerning as the Bearspaw South Feeder Main is currently offline for essential repairs, prompting city officials to label any usage above the threshold as falling into the “risky red zone.” The city is encouraging residents to adopt water-saving measures during this critical period.
Current Water Restrictions
The latest round of water restrictions was implemented on March 9 following the shutdown of the Bearspaw South Feeder Main—a vital infrastructure that typically supplies approximately 60 per cent of Calgary’s water. The shutdown is a response to two significant failures of the main within a two-year span. While repairs are ongoing, the city has been relying on the smaller Glenmore Water Treatment Plant, which also serves surrounding communities such as Airdrie, Chestermere, and Tsuut’ina Nation.
Infrastructure Repairs and Upgrades
Michael Thompson, the city’s general manager of infrastructure services, has reiterated the importance of conserving water during this time. “We aim to save 25 litres of water per person each day,” he stated. With household appliances such as dishwashers consuming around 28 litres per cycle and front-load washing machines using about 62 litres, even minor adjustments—like reducing the number of cycles—can collectively help meet or exceed the conservation target.
The current repair efforts involve reinforcing weakened sections of the feeder main. Thompson noted that rebar reinforcement has been completed, and concrete pouring is now underway. The city is also in the process of replacing the valves at the Shaganappi pump station, with work set to wrap up soon. Additionally, the refilling of one section of the feeder main will occur shortly, utilising approximately 5 million litres of water.
Future Construction Plans
Beginning March 24, the city will initiate construction on the final microtunnelling shaft at the intersection of 16th Avenue and 44th Street. This work will necessitate the establishment of a construction zone in a nearby parking lot, expected to remain in place until the project concludes in December. Residents can anticipate some traffic disruptions as these upgrades are carried out.
The current reinforcement efforts and water restrictions are expected to last for an additional two weeks, after which the feeder main should be back in operation. Concurrently, the city is working on a comprehensive replacement of the entire Bearspaw South Feeder Main, with the new steel infrastructure projected for completion by the end of 2026.
Why it Matters
The situation in Calgary underscores the delicate balance between maintaining essential water infrastructure and ensuring sustainable consumption practices among residents. As climate change increasingly impacts water availability, the city’s efforts to upgrade its systems while urging conservation become more crucial than ever. The outcomes of these repairs not only affect the immediate community but also set a precedent for future infrastructure resilience in the face of environmental challenges.
