Calgary residents have raised concerns as water consumption reached 501 million litres on Wednesday, just exceeding the city’s sustainable threshold of 500 million litres. This uptick in usage is particularly alarming as the Bearspaw South Feeder Main remains out of commission for crucial repairs. City officials are urging citizens to conserve water during this period, dubbing any usage above the recommended limit as falling into the “risky red zone.”
Current Water Restrictions
The latest water restrictions were imposed on March 9, coinciding with the shutdown of the Bearspaw South Feeder Main, which is responsible for supplying approximately 60 per cent of Calgary’s water. This action follows two significant failures of the feeder main within a two-year timeframe. In the absence of this vital infrastructure, the city has turned to the Glenmore water treatment plant, a far smaller facility that also serves nearby communities, including Airdrie, Chestermere, and the Tsuut’ina Nation.
The repairs, which are crucial for maintaining the integrity of the water supply system, involve reinforcing weakened concrete sections of the feeder main. Simultaneously, the city is working on a comprehensive replacement of the entire feeder main with a new steel pipe, expected to be operational by the end of 2026.
Community Efforts to Conserve Water
In light of the increased water usage, Michael Thompson, the city’s general manager of infrastructure services, has issued a renewed appeal for residents to limit their water consumption. During a recent update regarding the feeder main repairs, he highlighted the importance of individual contributions to water conservation.

“We aim to save 25 litres of water per person each day,” Thompson stated. “For instance, a single cycle of a dishwasher uses around 28 litres, and a front-loading washing machine consumes 62 litres. By opting for one less load daily, residents can meet or even exceed their daily conservation goals.”
The ongoing repairs include extensive rebar work to enhance the structural integrity of the feeder main, with concrete pouring currently underway and backfilling of excavated areas commencing. This reinforcement is expected to last for a further two weeks before the feeder main can be reactivated.
Upcoming Construction and Traffic Impacts
As part of the ongoing infrastructure work, Thompson announced that the replacement of valves at the Shaganappi pump station will be completed this weekend. He also noted that refilling one segment of the feeder main will utilise approximately 5 million litres of water.
Beginning March 24, construction will commence on the final microtunneling shaft located at 16th Avenue and 44th Street. A dedicated work zone will be established in the parking lot on the south side of 16th Avenue, and construction is projected to continue until December. Residents should prepare for some traffic disruptions as a result of this project.
Long-Term Water Management
The city’s efforts to reinforce the feeder main, alongside the ongoing restrictions, are expected to last until the system can be restored to service. Meanwhile, the complete replacement of the Bearspaw South Feeder Main with a new steel pipe is anticipated to be finalised by December, which will enhance the reliability of Calgary’s water supply.

Why it Matters
The implications of these infrastructure challenges are significant, not just for Calgary’s daily operations but also for its long-term water sustainability. As climate change intensifies, the need for robust water management strategies becomes increasingly pressing. By prioritising water conservation now, residents can play a vital role in safeguarding this essential resource for future generations, ensuring that Calgary remains resilient in the face of both environmental and infrastructural challenges.
