Overview
- City officials confirmed the break involves the Bearspaw South Feeder Main, the same trunk line that failed in June 2024.
- Crews stopped the flow and located the rupture, activated the Emergency Operations Centre, and closed sections of 16 Avenue NW as firefighters rescued 13 people from stranded vehicles with no serious injuries reported.
- Targeted boil-water advisories remain for parts of Montgomery, Parkdale and Point McKay, with about 2,000 homes and roughly 100 businesses initially affected.
- Stage 4 limits on outdoor water use are in place, and regional partners in Airdrie, Chestermere, Strathmore and Tsuut’ina Nation are urging conservation, with YMCA Calgary offering free showers to residents whose household water is fully shut off.
- Officials cited a rapid pressure drop before the burst and said the fibre‑optic monitoring showed no early warning, as the mayor cautioned that repairs will be complex and longer‑term pipe replacement is likely.
