Calgary residents are on the brink of having their water supply restored as the City has successfully refilled the Bearspaw South Feeder Main, setting the stage for the delivery of water to homes within days. This positive development follows extensive repair work on nine critical sections of the pipeline, which had been shut down since March 9.
Testing Underway for Safe Water Delivery
Michael Thompson, the City’s General Manager of Infrastructure Services, announced that water sampling and testing are currently in progress to ensure compliance with regulatory standards. “These tests take time, and this work is continuing throughout today,” Thompson stated. If all goes according to plan, the month-long water restrictions imposed on Calgarians could be lifted by Thursday, April 2.
Once testing confirms the water is safe, city teams will coordinate the opening of valves along the feeder main and initiate pumping operations at the Bearspaw Water Treatment Plant. “If everything proceeds as anticipated, we will turn on the pumps tomorrow,” Thompson added.
Temporary Adjustments and Ongoing Repairs
Typically, the Bearspaw Feeder Main is responsible for supplying approximately 60 per cent of Calgary’s water. During the repair period, the city has relied heavily on the smaller Glenmore Reservoir. As repairs continue, city crews have also commenced paving work on the roads that were disrupted to facilitate the repairs.
Residents should be prepared for possible temporary cloudiness in their water following the resumption of flow. “This is temporary and will take around 24 hours to clear,” Thompson assured, reiterating that the water is safe for consumption.
Mitigating Potential Risks
As the pumps are activated, the city has acknowledged the risk of additional breaks due to increased pressure in the pipeline. To counteract potential flooding in vulnerable areas like Bowness and Montgomery, temporary barriers have been installed to redirect excess water towards the Bow River, protecting homes and businesses from possible water damage.
On Sunday, Calgary’s overall water usage reached 500 million litres, of which 12 million litres were used to refill the feeder main. The consumption levels for residential and commercial purposes remained within sustainable limits, according to city officials.
Looking ahead, starting around April 9, the city plans to employ a specialised tool known as a pipe diver to conduct an internal inspection of the pipeline. This will necessitate briefly halting the water flow again to facilitate further testing and maintenance.
Why it Matters
The successful repair and upcoming resumption of the Bearspaw Feeder Main is crucial for Calgary’s water security, especially as the city navigates population growth and climate variability. With reliable water supply being a cornerstone of public health and community resilience, this development not only alleviates immediate concerns but also underscores the importance of investing in infrastructure to safeguard against future challenges.
