A water main break and a large sinkhole on Bowness Road in Calgary have caused significant disruptions for local businesses and traffic. The incident impacted approximately 20 businesses between 62nd and 63rd Street NW, leading to water outages and operational challenges. Some businesses reported being unable to serve food or access facilities, while others faced revenue losses and wasted inventory.

Following an initial repair on the 250 mm water distribution main, a second leak developed near the original site once water pressure was restored. City crews were required to return to the site to replace a section of the main. Local business owners and the Mainstreet Bowness Business Improvement Area noted that these infrastructure failures are recurring, citing previous ruptures in April, June 2024, and December 2025.
