Calgary is on the brink of restoring its water supply after successfully refilling the Bearspaw South Feeder Main. Following extensive repair work on nine critical sections of the pipe, city officials are optimistic that water could flow back into residents’ homes within days. Michael Thompson, the City of Calgary’s general manager of infrastructure services, provided an update, confirming that water quality testing is currently underway to ensure compliance with regulatory standards.
Significant Repair Milestone Achieved
The Bearspaw South Feeder Main, which typically supplies around 60 per cent of Calgary’s water, was taken offline for repairs on March 9. During this period, the city has depended heavily on the smaller Glenmore Reservoir to meet the community’s water needs.
“As we conduct the necessary tests to confirm the water’s safety, we’re hopeful that the month-long restrictions currently in place can be lifted by Thursday, April 2,” said Thompson. He added that once testing is complete, crews will be activated to open valves along the pipe and initiate the pumping process at the Bearspaw Water Treatment Plant.
Temporary Water Cloudiness Expected
Once the pumps are operational and the water begins to flow again, residents might experience some cloudiness in their tap water. However, Thompson reassured the public, stating, “This is a temporary issue and is expected to clear within approximately 24 hours. The water will be safe to drink.”
In anticipation of potential pressure-related issues as water begins to circulate through the system, the city has proactively installed temporary barriers in the Bowness and Montgomery communities. These measures aim to protect homes and businesses from possible flooding, directing excess water towards the nearby Bow River.
Future Inspections and Continued Monitoring
Looking ahead, Calgary plans to employ a specialised mechanical device known as a pipe diver for further inspections starting around April 9. This tool will assess the pipe’s condition as it exits the Bearspaw Water Treatment Plant. Following this inspection, the water flow will need to be briefly halted again to facilitate drainage and conduct additional safety tests.
As of Sunday, Calgary’s total water consumption was recorded at 500 million litres, with 12 million litres allocated for refilling the feeder main. Notably, water usage in homes and businesses remains within the city’s sustainable limits, reflecting responsible consumption during this challenging period.
Why it Matters
The restoration of the Bearspaw South Feeder Main is pivotal not only for immediate water supply but also for long-term infrastructure resilience in Calgary. The city has faced significant challenges over the past month, and the successful completion of these repairs will alleviate pressure on the Glenmore Reservoir while ensuring that stringent safety standards are upheld. As the community looks forward to the lifting of water restrictions, the proactive measures taken by city officials underscore the importance of maintaining a reliable and safe water supply for all residents.
