Calgary’s water consumption has recently surged, with residents utilising 501 million litres on Wednesday—just crossing the city’s 500 million litre threshold deemed sustainable. This spike occurs while the Bearspaw South Feeder Main undergoes critical repairs, prompting city officials to label any excess water use as entering the “risky red zone.” The city continues to urge residents to limit their water usage as it seeks to manage resources amid ongoing infrastructure challenges.
Infrastructure Challenges and Water Restrictions
The increased water consumption arrives just after two days of usage that fell below the recommended limit. The current restrictions, which began on March 9, were implemented following the shutdown of the Bearspaw South Feeder Main—responsible for supplying approximately 60 per cent of Calgary’s water. This shutdown results from two significant failures in less than two years, necessitating extensive repairs to several weakened concrete sections of the feeder main.
During this downtime, the city is reliant on the Glenmore Water Treatment Plant, which has a considerably lower capacity, to meet the water needs of Calgary and surrounding areas, including Airdrie, Chestermere, and the Tsuut’ina Nation.
City Officials Urge Conservation
In light of the recent surge in water use, Michael Thompson, the city’s General Manager of Infrastructure Services, renewed calls for residents to conserve water. “Our goal is to save 25 litres of water per person each day,” Thompson stated during a Thursday briefing concerning the feeder main repairs. He pointed out that reducing just one cycle of dishwashing or laundry each day could help achieve or surpass this target.

Thompson also provided updates on the repair work. The rebar reinforcement of weakened sections of the feeder main has been completed, and concrete pouring is currently underway. Additionally, backfilling around several sections has commenced.
“Replacement of the valves at the Shaganappi pump station will be wrapped up this weekend,” he added. “We will also begin refilling one section of the feeder main, which will require approximately 5 million litres of water.”
Future Steps in Water Management
Looking ahead, the city plans to initiate construction on the final microtunneling shaft on March 24 at 16th Avenue and 44th Street. This work will necessitate a designated construction area in the parking lot on the south side of 16th Avenue and is expected to cause temporary traffic disruptions until its completion in December.
The current reinforcement measures and water restrictions are anticipated to last for an additional two weeks before the feeder main is restored to service. Alongside these immediate repairs, Calgary is also in the process of replacing the entire Bearspaw South Feeder Main with a new steel pipe, with completion projected for December.
Why it Matters
The situation in Calgary underscores the critical balance between urban water management and environmental stewardship. As the city grapples with infrastructure demands, the call for conservation becomes ever more urgent. This incident highlights the necessity for residents to engage in sustainable practices, ensuring that water resources are preserved for future generations while simultaneously addressing the pressing need for robust infrastructure that can withstand the challenges posed by climate change and population growth.
