Calgary’s water consumption reached a concerning 501 million litres on Wednesday, slightly exceeding the city’s sustainable limit of 500 million litres. This spike in usage comes during the ongoing shutdown of the Bearspaw South Feeder Main for essential repairs, prompting city officials to urge residents to be more mindful of their water consumption.
Infrastructure Under Strain
The Bearspaw South Feeder Main, which typically provides around 60% of Calgary’s water supply, has been out of operation since March 9 due to significant failures in its structure. The city is currently relying on the smaller Glenmore water treatment plant to meet the needs of Calgary and surrounding areas, including Airdrie and Chestermere, as well as Tsuut’ina Nation.
City officials have referred to water usage above the recommended threshold as entering “the risky red zone,” underscoring the importance of conservation efforts. The recent increase in water use follows two days where consumption fell below the 500 million-litre mark, showing the community’s fluctuating adherence to conservation measures.
Repair Work Progress
City General Manager of Infrastructure Services, Michael Thompson, addressed the growing concerns during a recent update, emphasising the need for residents to conserve water. “We aim to save 25 litres of water per person each day,” Thompson stated. He pointed out that reducing laundry and dishwashing cycles can significantly contribute to achieving this goal, as a typical dishwasher consumes around 28 litres per cycle, while a front-load washing machine uses about 62 litres.
The repairs on the feeder main involve reinforcing weakened concrete sections, and work on this has progressed, with rebar installation completed and concrete pouring underway. Backfilling around certain sections has also begun, signalling positive movement towards restoring service.
Upcoming Construction and Impact
The city is set to initiate construction on the final microtunneling shaft on 16th Avenue at 44th Street on March 24, with work expected to continue until December. A designated construction area will be established in a parking lot on the south side of 16th Avenue, which may lead to traffic disruptions in the vicinity.
Thompson also noted that the replacement of valves at the Shaganappi pump station would be finalised over the weekend. Refilling one section of the feeder main will require an estimated 5 million litres of water, further complicating the conservation message amidst ongoing repairs.
Sustained Efforts for the Future
The combination of current water restrictions and infrastructure upgrades is projected to last for at least another two weeks. As the city aims to replace the ageing Bearspaw South Feeder Main with a new steel pipe by the end of 2026, the situation continues to highlight the pressing need for sustainable water management practices in Calgary.
Why it Matters
The implications of Calgary’s rising water use during this critical period extend beyond immediate conservation needs. As the city grapples with ageing infrastructure and the pressing demands of a growing population, the situation serves as a poignant reminder of the importance of sustainable water practices. Community engagement in water conservation not only helps mitigate current shortages but also lays the groundwork for a resilient future, ensuring that Calgary can sustainably manage its water resources amid changing environmental conditions.
