Calgary residents can soon expect a return to normal water supply, as the city has successfully refilled the Bearspaw South Feeder Main. After completing critical repairs on nine sections of the pipeline, officials are now conducting tests to ensure the water meets regulatory standards. If all goes according to plan, water deliveries to homes could resume as early as this Thursday.
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.” The feeder main, which usually supplies approximately 60 per cent of Calgary’s water, was taken offline on March 9 for necessary repairs. During this period, the city has relied heavily on the Glenmore Reservoir, which has much lower capacity.
Once water quality testing confirms safety, the city will open valves along the pipeline and activate the pumps at the Bearspaw Water Treatment Plant. Thompson noted, “If everything goes as planned, we will turn on the pumps tomorrow.”
Impact of Repairs on Residents
As proceedings unfold, residents should be prepared for potential cloudiness in their water supply. “This is temporary and will take around 24 hours to clear,” Thompson assured, adding that the water remains safe for consumption. Additionally, the city has implemented precautionary measures to mitigate the risk of flooding due to increased pressure in the pipes. Temporary barriers have been erected in communities such as Bowness and Montgomery to protect local homes and businesses, directing any excess water towards the Bow River.
Despite the ongoing repairs, Calgary’s water consumption remains within sustainable limits. On Sunday, the city recorded a total usage of 500 million litres, of which only 12 million litres were allocated to refill the feeder main. This indicates that residents have been conserving water effectively during the restrictions.
Future Inspections Planned
Looking ahead, the city is set to deploy a specialised mechanical tool known as a pipe diver on April 9 to conduct an internal inspection of the pipeline where it exits the Bearspaw water treatment facility. Following this inspection, crews will need to briefly halt water flow to drain the pipeline, remove the pipe diver, and conduct further tests to ensure the system is safe for use.
This thorough inspection and testing process is essential to maintaining the integrity of Calgary’s water supply systems, particularly after the extensive repairs.
Why it Matters
The reinstatement of the Bearspaw South Feeder Main is crucial not only for restoring normal water supply to Calgary households but also for ensuring the city’s long-term water security. With the ongoing challenges posed by climate change and population growth, maintaining a reliable water infrastructure is critical. The successful completion of these repairs and the subsequent lifting of water restrictions demonstrate Calgary’s commitment to both public health and environmental stewardship.
