Calgary's Water Main Woes: A Deepening Crisis

Calgary is grappling with an increasing number of water main breaks, underscoring the vulnerability of its aging infrastructure. As of November 2025, recent data from the City of Calgary indicate a worrying rise in these incidents compared to previous years. Last year's major break in the Bearspaw South feeder main highlighted the severe impact such events can have on residents and the local economy.

The city manages over 16,000 kilometres of underground pipes, and despite efforts to minimize disruptions, significant challenges remain. Contributing factors to these breaks include the average pipe age of 53 years and the harsh freeze-thaw cycles intrinsic to Calgary's climate. The ongoing maintenance costs throughout North America—$2.6 billion annually—paint a clear picture of the widespread issue.

Policy and Community Reactions

City officials are implementing proactive measures such as a Water Main Replacement Program, which has reduced emergency repairs by 73% since 1980. However, a growing 'infrastructure deficit' estimated at $7 billion necessitates further action. Proposed developments include new feeder mains and substantial financial investments.

Community voices, from the Calgary Construction Association to residents, stress the urgency of these developments. As infrastructure ages amidst rapid population growth, Calgarians are concerned about maintaining quality of life and preventing disruptions. This situation raises critical questions on balancing necessary infrastructure improvements with affordability.

As Calgary navigates these challenges, the city's approach will undoubtedly shape the future of its infrastructure resilience and economic vitality.
