Calgary officials asked every person on the city’s water system on Jan. 8, 2026, to save 30 litres a day — equal to three fewer toilet flushes — while crews repaired the Bearspaw South Feeder Main, which ruptured Dec. 30 and normally carries 60 per cent of Calgary’s treated water.
Three flushes, 30 litres, one target
Sue Henry, chief of the Calgary Emergency Management Agency, put the request in the simplest terms she could on Jan. 8. If each person saved 30 litres a day, the city would meet its daily conservation target while a fragile feeder main was repaired.
Henry equated that saving to flushing the toilet three fewer times a day. The city’s Jan. 8 update listed the same actions: flushing only when needed — skipping three flushes saves about 30 litres — and shortening showers, with every minute saved cutting up to eight litres.
Running dishwashers and washing machines only with full loads was the third action the city repeated in each update.
The arithmetic matters because the system had little margin. On Wednesday, Jan. 7, Calgarians used 507 million litres of water, above the target zone of 485 million litres that officials said would let the system operate safely, refill overnight and keep water available for emergencies.
“Calgary’s water system is under significant strain, and while we’ve seen encouraging signs of reduced consumption, we are still operating with very limited capacity to respond to any unexpected events,” Henry said in the city’s Jan. 8 update.
A main that carries most of the city
The Bearspaw South Feeder Main carries about 60 per cent of Calgary’s treated water. It ruptured on Dec. 30, and since then residents have, on almost every day, used more water than could be replenished, according to The Canadian Press report published Jan. 8.
That imbalance is the core risk officials described. Meeting the daily target would ensure enough water remained for emergencies such as firefighting while the main was out of service. Drawing down stored supply day after day would gradually reduce the city’s ability to keep the system stable if another problem occurred.
The strain was not limited to Calgary itself. The city’s later updates noted the same saving request applied to everyone who relies on Calgary’s water system, including surrounding communities. The request was therefore framed as a regional one, not a household suggestion for a single neighbourhood.
Repair work was already advancing
The Jan. 8 city update also reported progress at the break site that was not in the first wire reports. The damaged section had been removed, the new pipe was in place and welded, and crews had begun backfilling the area. Road repairs above the pipe were to follow once the critical steps to restore water service were complete.
Restoring service, the city explained, involved four main steps, starting with filling the feeder main and water quality testing before flow could be returned to normal. Mandatory Stage 4 water restrictions were to remain in place until the pipe was fully restored and service was back to normal.
The Canadian Press, citing officials on Jan. 8, said the line was expected to be up and running as early as the following week. That timeline still depended on the testing and refilling steps going without a setback, which is why officials continued to press for conservation even as the physical repair neared completion.
Small cuts at city facilities, too
The city said organizations and communities across the region were reducing non-essential water use by adjusting operations, reusing water where possible and pausing activities such as rink flooding and decorative water features.
City recreation centres had closed steam rooms and adjusted wave pool and water slide hours to reduce use, according to the Jan. 8 update. Officials presented those steps as evidence that the saving was being shared, and that small actions added up when multiplied across more than a million people.
For residents, the message on Jan. 8 remained unchanged and deliberately plain: flush only when needed, take shorter showers, and run full loads only, until the feeder main that carries most of Calgary’s water was safely back in service.
