Calgary is on the brink of lifting its month-long water restrictions, following the successful refilling of the Bearspaw South Feeder Main. Recent repair work on nine critical sections of the pipeline has now been completed, with testing underway to ensure the water meets safety standards before it resumes service to residents.
Testing Underway for Safe Water Supply
Michael Thompson, the City of Calgary’s general manager of infrastructure services, confirmed that water sampling and testing are currently in progress. “These tests take time, and this work is continuing throughout today,” Thompson stated. If results come back positive, the city anticipates being able to lift the restrictions as early as Thursday, April 2.
Once the water is deemed safe, the city will coordinate the opening of valves along the feeder main and start activating the pumps at the Bearspaw Water Treatment Plant. “If everything goes according to plan, we will turn on the pumps tomorrow,” Thompson added, raising hopes for a swift return to normalcy for Calgary’s water supply.
Transition from Glenmore Reservoir
The Bearspaw South Feeder Main typically supplies approximately 60 per cent of Calgary’s water. Since its shutdown for repairs on March 9, the city has been relying heavily on the smaller Glenmore Reservoir to meet demand. On Sunday, total water consumption in Calgary reached 500 million litres, of which 12 million litres were used to refill the feeder main. Remarkably, the city’s water usage has remained within sustainable levels during this period.
With repairs now largely complete, the city has also commenced paving work on the roads that were disrupted during the repair process, marking a significant step towards restoring full services.
What to Expect When Water Returns
Residents may experience temporary cloudiness in their tap water once it begins flowing again. “This is temporary and will take about 24 hours to clear,” Thompson assured, emphasising that the water will remain safe to drink during this period. However, as pressure increases in the repaired pipe, there remains a risk of further breaks. To mitigate potential flooding, temporary barriers have been installed in vulnerable neighbourhoods, including Bowness and Montgomery, directing any excess water towards the nearby Bow River.
Future Inspections Planned
Beginning April 9, the city will employ a specialised tool known as a pipe diver for an internal inspection of the pipeline at its exit point from the Bearspaw Water Treatment Plant. Following this inspection, crews will need to briefly halt water flow to drain the pipe and conduct further safety tests. This proactive approach underscores the city’s commitment to maintaining a reliable water supply for its residents.
Why it Matters
The successful repair and impending restoration of the Bearspaw South Feeder Main represents a critical moment for Calgary, relieving residents from ongoing water restrictions and restoring access to a vital resource. This development highlights the importance of robust infrastructure and responsive city management in ensuring public health and safety. As the city grapples with environmental challenges and infrastructure demands, the situation serves as a reminder of the delicate balance between urban development and environmental stewardship in Western Canada.
