Calgarians may soon see the end of their month-long water restrictions as the City of Calgary announces significant progress on repairs to the Bearspaw South Feeder Main. The city has successfully refilled the main with water and is now in the process of conducting safety tests, with hopes of resuming normal water delivery to homes within days.
Repairs Completed and Testing Underway
Following extensive repair work on nine critical sections of the Bearspaw feeder pipe, the city has filled the main with water. Michael Thompson, the General Manager of Infrastructure Services, stated, “We are now sampling and testing water to ensure it meets or exceeds regulatory requirements. These tests are ongoing today.”
If testing results are satisfactory, water restrictions currently imposed on residents could be lifted as early as Thursday, April 2. Thompson added, “Once testing shows that the water is safe, teams will coordinate the opening of valves along the pipe and begin to turn on the pumps at the Bearspaw Water Treatment Plant.”
Transition to Glenmore Reservoir
Since the feeder main was shut down for repairs on March 9, the city has relied heavily on the Glenmore Reservoir, which is significantly smaller than the Bearspaw supply. Typically, the Bearspaw main accounts for approximately 60 per cent of Calgary’s water supply, making the reliance on Glenmore a temporary yet strained solution.
As of Sunday, Calgary consumed around 500 million litres of water, with 12 million litres used to refill the feeder main. This indicates that overall domestic and commercial water usage remains within sustainable levels, a crucial aspect as the city navigates these repairs.
Potential Challenges Ahead
Once normal operations resume, residents may experience some cloudy water as the system stabilises. “This is temporary and should clear up within 24 hours,” Thompson reassured, emphasising that the water will remain safe to drink during this period.
However, there are concerns that the increased pressure in the pipe could lead to further breaks. To mitigate potential flooding, the city has installed temporary barriers in communities such as Bowness and Montgomery, directing excess water towards the Bow River.
Future Inspections Planned
Looking ahead, the city plans to conduct an internal inspection of the pipe using a specialised mechanical tool known as a pipe diver. This inspection is set to take place around April 9, and will require another brief halt to water flow for safety measures, followed by further testing to ensure water quality is maintained.
Why it Matters
The restoration of the Bearspaw South Feeder Main is a pivotal moment for Calgary, not only in terms of water supply but also for the city’s infrastructure resilience. As Calgary continues to grow, maintaining a robust and reliable water system is essential for both residents and businesses. The challenges faced during this repair process highlight the importance of proactive infrastructure management, especially in the face of environmental considerations and increasing demands on water resources. The city’s efforts to balance immediate needs with long-term sustainability will be crucial in shaping Calgary’s water future.
