Alberta government launches review of Calgary water main breaks, requests city records

The Alberta government has initiated a formal review of Calgary’s recurring water main failures, requesting extensive records from the city spanning the past 20 years.

Municipal Affairs Minister Dan Williams said in a letter to Calgary officials, shared publicly on social media, that the review aims to ensure the city’s 1.6 million residents have access to safe and reliable water services.

Williams noted that while the city is actively addressing the latest rupture, the province must take steps to prevent future incidents. The concerns focus on the Bearspaw South Feeder Main, a key pipeline responsible for transporting roughly 60 per cent of treated water to Calgary and nearby communities.

The pipeline has failed twice in under two years, prompting water-use restrictions for residents. The most recent rupture occurred late last month, and officials continue to advise residents to take shorter showers and limit toilet flushing until full service is restored.

The review will examine maintenance practices, emergency response procedures, and long-term infrastructure planning for Calgary’s water system.
