The City of Calgary is on the verge of lifting water restrictions imposed on residents for nearly a month, as significant repair works on the Bearspaw South Feeder Main approach completion. Following the successful refilling of the main pipeline, the city is now conducting water quality tests to ensure safety standards are met before resuming full water services to households.
Water Testing Underway
Michael Thompson, the general manager of infrastructure services for Calgary, provided an update on the situation, stating, “We are now sampling and testing water to make sure it meets or exceeds regulatory requirements. These tests take time and this work is continuing throughout today.” If these tests yield positive results, water could start flowing again as early as Thursday, April 2nd, marking a significant milestone for the city.
The Bearspaw South Feeder Main, which supplies approximately 60 per cent of Calgary’s water, was taken offline on March 9 for repairs after critical issues were discovered in nine sections of the pipeline. During this period, the city has been relying heavily on the Glenmore Reservoir to meet its water demands.
Residents Prepared for Temporary Changes
Once the testing indicates that the water is safe for consumption, city crews will coordinate the reactivation of valves and pumps at the Bearspaw Water Treatment Plant. Thompson noted that residents might experience some cloudiness in their tap water as the system is restarted. “This is temporary and will take around 24 hours to clear,” he explained, assuring residents that the water remains safe to drink.
However, the return to normal water service does come with a caveat. The increased pressure in the pipeline could potentially lead to additional breaks. To address this risk, temporary barriers have been installed in the Bowness and Montgomery communities to protect properties from any flooding that may occur.
Infrastructure Restoration Progress
In addition to the water supply updates, paving work has begun on the streets that were disrupted during the repairs to the feeder main. This restoration is part of a broader effort to ensure that the city’s infrastructure remains resilient and capable of supporting Calgary’s needs.
As of Sunday, the total water consumption in Calgary stood at 500 million litres, with 12 million litres utilised to refill the feeder main. Importantly, the levels of domestic water use remained within sustainable limits, reflecting the community’s adaptability during this challenging period.
Future Inspections Planned
Looking ahead, the city is set to undertake further inspections of the pipeline, with plans to deploy a specialised mechanical tool known as a pipe diver on April 9. This tool will facilitate an internal assessment of the feeder main as it exits the Bearspaw Water Treatment Plant. Following this inspection, water flow will need to be briefly halted again to enable further safety testing.
Why it Matters
The successful restoration of the Bearspaw South Feeder Main is crucial not only for ensuring a reliable water supply for Calgarians but also for the overall resilience of the city’s water infrastructure. As climate challenges intensify, maintaining and upgrading such systems is vital for safeguarding public health and mitigating environmental impacts. The actions taken by the City of Calgary serve as a reminder of the importance of proactive infrastructure management in the face of growing urban demands and potential environmental shifts.
