The City of Calgary has announced significant progress in the repair of the Bearspaw South Feeder Main, with water delivery to residents expected to resume shortly. Following extensive work on nine critical sections of the pipeline, the city is currently conducting water quality testing to ensure it meets safety standards. If all goes according to plan, the long-standing water restrictions could be lifted as early as Thursday.
Repairs and Testing Underway
Michael Thompson, the general manager of infrastructure services for Calgary, confirmed that the refilling of the Bearspaw South Feeder Main has been completed. The feeder main typically supplies approximately 60 per cent of the city’s water, but was shut down for repairs on 9 March, forcing Calgary to rely heavily on the smaller Glenmore Reservoir for its water supply.
“We are now sampling and testing the water to ensure it meets or exceeds regulatory requirements,” Thompson stated. He emphasised that while the testing process is ongoing, it is crucial for the safety of residents.
Once testing confirms that the water is safe for consumption, city teams will coordinate to open valves along the feeder main and activate pumps at the Bearspaw Water Treatment Plant. “If all goes as planned, we will turn on the pumps tomorrow,” Thompson added.
Temporary Challenges Ahead
As the water flow resumes, residents may experience cloudy water when they turn on their taps. “This is temporary and should clear up within 24 hours,” Thompson reassured the public, adding that the water remains safe to drink during this period.
It is important to note that the reactivation of the pumps could increase pressure on the pipeline, which may pose a risk of further breaks. To mitigate potential flooding, the city has installed temporary barriers in the Bowness and Montgomery communities, directing excess water towards the nearby Bow River.
Looking to the Future
While the immediate focus is on restoring water service, Calgary officials are also preparing for an upcoming internal inspection of the pipe. Beginning around 9 April, crews will deploy a specialised mechanical tool known as a ‘pipe diver’ to assess the condition of the pipeline. Following this inspection, water flow will need to be temporarily halted again to ensure comprehensive testing and safety verification.
On Sunday, Calgary’s total water consumption was recorded at 500 million litres, with 12 million litres used to refill the feeder main. Officials noted that this level of usage remains within sustainable limits, a positive sign for the city as it navigates these repairs.
Why it Matters
The restoration of the Bearspaw South Feeder Main is not just a logistical victory for Calgary; it is a crucial step towards ensuring reliable access to safe drinking water for its residents. With the lifting of water restrictions on the horizon, the city can begin to return to normalcy. This situation underscores the importance of maintaining robust infrastructure to support a growing urban population, while also highlighting the delicate balance between environmental stewardship and the demands of everyday life. As Calgary moves forward, ongoing investments in water systems will be essential to prevent future disruptions and safeguard public health.
