Overview
- The Bearspaw South Feeder Main was taken out of service Monday for roughly four weeks of reinforcement and normally supplies about 60% of Calgary’s treated water.
- A citywide ban on outdoor water use is in effect, and residents are asked to cut indoor consumption by about 25 litres per person daily through short showers, skipped flushes and only running full loads.
- With supply constrained to the Glenmore Water Treatment Plant operating at maximum capacity, the city aims to keep total daily demand below 500 million litres.
- Officials warn that exceeding that limit could lead to insufficient water for firefighting, low pressure, boil‑water advisories or even system failure.
- Crews have shut Bearspaw plant pumps, isolated and drained the line, and will reinforce nine pipe sections as lane reductions and ramp closures occur near 16 Avenue NW and Sarcee Trail; restrictions also cover Airdrie, Chestermere, Strathmore and the Tsuut’ina Nation, with a Bowness resource centre open to support residents and a replacement line targeted for completion by year‑end.
