The City of Calgary is on the brink of lifting month-long water restrictions as repairs to the Bearspaw South Feeder Main have been successfully completed. Following extensive work on nine critical sections of the pipeline, the city is now engaged in final water testing, with hopes to resume normal water delivery to residents in a matter of days.
Repair Work and Testing Underway
After shutting down the Bearspaw South Feeder Main on March 9 for urgent repairs, the city has relied on the smaller Glenmore Reservoir to meet the water demands of Calgarians. Michael Thompson, the city’s general manager of infrastructure services, confirmed that the pipeline has been refilled, saying, “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.”
Thompson indicated that if tests confirm the water’s safety, crews will open valves and activate the pumps at the Bearspaw Water Treatment Plant, potentially restoring full water service by Thursday, April 2.
Temporary Cloudiness Expected
Once the pumps are operational, residents may initially experience cloudy water from their taps. “This is temporary and will take about 24 hours to clear,” Thompson reassured, emphasising that the water remains safe for consumption. To mitigate any risks associated with increased water pressure, the city has installed temporary barriers in the Bowness and Montgomery neighbourhoods to manage potential flooding and direct excess water towards the Bow River.
Future Inspections Planned
In a bid to ensure the integrity of the repaired feeder main, Calgary plans to conduct further assessments. Starting around April 9, a specialised tool known as a pipe diver will be employed to inspect the section of the pipeline from the Bearspaw Treatment Plant. This will require another brief shutdown of water flow to facilitate the inspection, after which further testing will be conducted to confirm water safety.
Despite the challenges posed by the repair work, Calgary’s overall water usage remained within sustainable limits, with residents consuming around 500 million litres on Sunday, of which only 12 million litres were used to refill the feeder main.
Why it Matters
The successful repair of the Bearspaw South Feeder Main and the anticipated lifting of water restrictions are crucial for Calgary’s infrastructure resilience. As the city continues to grow, ensuring a stable and safe water supply is essential not only for public health but also for the sustainable development of the region. The proactive measures undertaken by the city highlight the importance of maintaining essential services, particularly in balancing environmental concerns with the demands of a burgeoning population.
