Calgary’s Stage 4 outdoor water restrictions took effect Wednesday as crews began connecting the replacement Bearspaw South Feeder Main, starting an expected four-week period of reduced water availability.

The city says the existing main must be shut down during the connection work, leaving the region primarily dependent on the Glenmore Water Treatment Plant. Officials want daily demand kept below 500 million litres to protect essential service and firefighting capacity.

Residents and businesses face restrictions on outdoor water use, including flooding skating rinks. Calgary is also asking people in Airdrie, Chestermere, Strathmore and Tsuut’ina Nation to conserve water indoors by shortening showers, waiting for full laundry and dishwasher loads, and avoiding unnecessary toilet flushing.

The interruption reaches beyond household routines. The Canadian Press reported Wednesday that the restrictions also prevent snowmaking at ski hills, with WinSport unable to obtain an exemption for its Canada Olympic Park operations.

WinSport has not set an opening date for its ski and snowboard hill. Warmer conditions would likely have delayed opening anyway, a spokesperson told the news agency.

Hockey Calgary said its indoor programs remained operational and it had received no indication of schedule changes, although individual facilities would decide how to manage ice flooding.

The work also overlaps with Calgary’s Grey Cup festival, scheduled for November 11–15.

After the connection, the new pipe still needs filling, flushing and water-quality testing before its planned entry into service in December. The city plans daily updates showing consumption against its target while the restrictions remain in place.
