Calgary’s water consumption hit 501 million litres on Wednesday, surpassing the city’s sustainable threshold of 500 million litres, while the Bearspaw South Feeder Main undergoes crucial repairs. This uptick in usage comes after two days of lower consumption, prompting city officials to urge residents to conserve water during this challenging period.
Water Use Exceeds Recommended Limits
City authorities have labelled any water use above the 500 million litre mark as falling into the “risky red zone.” This terminology is part of a broader initiative to encourage Calgarians to be mindful of their water consumption during the feeder main’s downtime, which is expected to last for several weeks. The Bearspaw South Feeder Main typically supplies around 60 per cent of Calgary’s water, and its shutdown has necessitated reliance on the smaller Glenmore water treatment plant, which also serves nearby communities such as Airdrie, Chestermere, and the Tsuut’ina Nation.
The feeder main was taken offline on March 9 due to structural failures that have occurred twice in less than two years. As the city grapples with this water crisis, officials are keenly aware of the need for residents to adjust their habits.
City Officials Call for Conservation
Michael Thompson, Calgary’s general manager of infrastructure services, reiterated the importance of conservation during a recent update on the repairs. “We aim to save 25 litres of water per person each day,” he stated. He highlighted practical measures residents can take, such as reducing the frequency of using dishwashers and washing machines, which can consume significant amounts of water per cycle.

Thompson also noted that reinforcing weakened sections of the feeder main is progressing well, with rebar installation completed and concrete pours now underway. Work around the feeder main’s excavations has commenced, which is crucial for restoring the water supply infrastructure.
Upcoming Repairs and Construction Plans
As part of the repair strategy, valve replacements at the Shaganappi pump station are scheduled for completion this weekend. However, this process will require approximately 5 million litres of water to refill one section of the feeder main. Furthermore, construction is set to start on March 24 for the final microtunnelling shaft at the intersection of 16th Avenue and 44th Street, with the work expected to persist until December. This will inevitably lead to some traffic disruptions in the area.
The city anticipates that the reinforcement work and current water restrictions will remain in place for another two weeks, after which the feeder main is expected to return to service. Simultaneously, the entire feeder main is being replaced with a new steel pipe, aiming for completion by the end of 2026.
The Broader Context of Water Management
This situation highlights a pressing need for the city to not only address immediate infrastructure concerns but also to promote long-term sustainable water management practices. As Calgary continues to grow, the balance between development and environmental stewardship becomes increasingly vital.

Why it Matters
The ongoing water restrictions in Calgary underscore the delicate balance between urban growth and environmental sustainability. As the city navigates the complexities of maintaining its water infrastructure, the community’s response to conservation efforts will be crucial. With climate change placing additional pressures on water resources, how residents adapt their consumption habits now could set a precedent for future conservation initiatives, ultimately shaping Calgary’s environmental landscape for years to come.
