The City of Calgary is on the verge of lifting its month-long water restrictions following the successful refilling of the Bearspaw South Feeder Main. After extensive repairs to nine critical sections of the pipeline, officials anticipate resuming water delivery to residents within days, pending water quality tests.
Repairs Completed and Testing Underway
Michael Thompson, Calgary’s general manager of infrastructure services, confirmed that the city has finished the necessary pipeline repairs and is now engaged in rigorous testing to ensure the water quality meets or exceeds safety standards. “We are currently sampling and testing water, which is a time-consuming process that will continue throughout today,” Thompson stated, highlighting the meticulous nature of the water safety checks.
According to Thompson, if testing results are favourable, the water restrictions imposed on March 9 may be lifted as soon as Thursday, April 2. The Bearspaw South Feeder Main typically supplies approximately 60 per cent of Calgary’s water, and since its shutdown, the city has been relying on the much smaller Glenmore Reservoir to meet demand.
Restoration Efforts and Future Precautions
In addition to the pipeline work, crews have begun repaving roads that were disrupted during the repair process. As the city prepares to restart the water flow, residents should be aware that they may experience temporary cloudiness in their tap water. “This is a normal occurrence and should clear up within 24 hours,” Thompson reassured. He also confirmed the water remains safe to consume.
However, as the water is reintroduced to the feeder main, there exists a possibility of additional breaks due to the increased pressure within the system. To mitigate potential flooding risks, temporary barriers have been installed in the communities of Bowness and Montgomery, directing excess water towards the Bow River.
Future Inspections and Ongoing Management
Calgary’s water consumption has remained within sustainable limits, with total usage recorded at 500 million litres on Sunday. Notably, 12 million litres were allocated to refill the feeder main. This careful management has allowed the city to maintain its water supply without overextending resources during the repair period.
Looking ahead, the city intends to utilise a specialised tool known as a pipe diver for an internal inspection of the feeder main, set to commence around April 9. Following this inspection, crews will need to temporarily halt water flow again to drain excess water, remove the pipe diver, and conduct further safety tests.
Why it Matters
The successful repair and impending resumption of water services are crucial for Calgary’s residents, not only for everyday convenience but also for public health and safety. With the city’s water supply largely reliant on the Bearspaw system, restoring full functionality will enhance service reliability and reduce the risks associated with prolonged water restrictions. Moreover, the proactive measures taken to protect vulnerable communities highlight Calgary’s commitment to ensuring its infrastructure can withstand future challenges amidst changing environmental conditions.
