Calgary’s water usage has surged to 501 million litres on Wednesday, exceeding the city’s sustainable limit of 500 million litres, as residents grapple with ongoing water restrictions related to the Bearspaw South Feeder Main being offline for repairs. This spike in consumption comes after two days of compliance, highlighting the challenges faced by the community during this critical period of infrastructure maintenance.
Water Use Exceeds Recommended Levels
City officials have labelled this overconsumption as entering “the risky red zone,” urging Calgarians to limit their water usage in light of the current restrictions. The Bearspaw South Feeder Main, which typically delivers around 60 per cent of Calgary’s water supply, has been out of service since March 9 due to necessary repairs following multiple failures in recent years.
During this downtime, the city has turned to the smaller Glenmore water treatment plant, which also supplies water to neighbouring communities such as Airdrie, Chestermere, and the Tsuut’ina Nation. The reliance on this limited resource underscores the urgency of conserving water in the face of infrastructure challenges.
Infrastructure Upgrades Underway
Michael Thompson, Calgary’s general manager of infrastructure services, reiterated the city’s commitment to water conservation during a recent update on the repairs. “We aim to save 25 litres of water per person each day,” he stated, illustrating how simple changes in household routines, such as reducing dishwasher or washing machine cycles, can significantly impact overall consumption.
As repair work progresses, crews have completed essential rebar reinforcement of weakened sections of the feeder main, with concrete pouring now underway. Upcoming tasks will include replacing valves at the Shaganappi pump station, a project expected to wrap up this weekend. However, this process will necessitate the use of approximately 5 million litres of water to refill one section of the feeder main.
Construction and Traffic Impacts
On March 24, construction will commence on the final microtunneling shaft at the intersection of 16th Avenue and 44th Street. This construction site will be located in a nearby parking lot, remaining in place until the work is completed in December. Residents should prepare for intermediate traffic disruptions as crews carry out these critical upgrades.
With the reinforcement efforts and water restrictions anticipated to last at least another two weeks, the city is simultaneously progressing on the replacement of the entire Bearspaw South Feeder Main with a new steel pipe, slated for completion by the end of 2026.
Why it Matters
The situation in Calgary serves as a poignant reminder of the delicate balance between urban infrastructure and environmental stewardship. As the city strives to upgrade its water systems, the community’s role in conserving resources is paramount. This incident not only highlights the immediate necessity for responsible water use amid repairs but also reflects broader challenges faced by urban centres in managing ageing infrastructure while promoting sustainability. The long-term health of Calgary’s water supply depends on both effective repairs and the collective efforts of its residents to protect this vital resource.
