A major water main break in Calgary has triggered a city-wide plea to conserve water, but the response has been underwhelming. Despite urgent requests from city officials, residents haven't significantly reduced their water consumption. This situation puts the city in a precarious position, and here's why...
Following Tuesday's catastrophic water main break, officials immediately asked Calgarians to cut back on their water usage. However, the city hasn't seen any real reduction in water consumption. Mayor Jeromy Farkas stated that the city is 'still very much in the red zone,' meaning demand is exceeding what the system can sustainably provide.
To put this into perspective, Calgary typically stores about 600 million litres of water underground daily. After the break in the Bearspaw south feeder main, this dropped to 459 million litres. While there was a slight rebound, more water needs to be saved to prevent depletion, according to Michael Thompson, the city’s infrastructure services general manager.
Calgarians are encouraged to conserve water by taking shorter showers (three minutes or less), limiting toilet flushing, and running dishwashers and washing machines only when full. Chris Huston, the city’s manager of the drinking water distribution system, pointed out that each minute saved in the shower could conserve six to eight litres of water. If everyone could reduce their daily intake by 10-30 litres, it would greatly help reach the target usage.
The city aims to repair the broken pipe within two weeks. Businesses are also asked to help by refilling water glasses only when requested and using bottled water where possible.
But here's where it gets controversial...
Sue Henry, Calgary Emergency Management Agency chief, acknowledged the inconvenience and stressed the critical need to reduce water use. A boil water advisory remains in effect for parts of Montgomery, West Hillhurst, Parkdale, and Point McKay.
City officials are unsure what caused this week's failure, and Chris Huston admitted they 'can’t guarantee 100 per cent' that another break won't occur. Following a catastrophic break in 2024, the city planned to replace the Bearspaw south feeder main with a new steel pipe, a project now being expedited. They were using an acoustic fibre optic monitoring system to detect wire snaps, which would indicate breaks inside the pipe. However, no snaps were heard in the two months leading up to Tuesday’s break.
Interestingly, only 18 snaps were detected across the entire feeder main since monitoring began, compared to 20 snaps in July and August 2024. Thompson noted they believed the pipe was stable, although they knew it needed work. Mayor Farkas said the Bearspaw south feeder main has reached the end of its reliable lifecycle.
And this is the part most people miss...
This situation highlights the urgency of infrastructure maintenance and the importance of community cooperation during emergencies. It also raises questions about the effectiveness of current monitoring systems and the long-term sustainability of aging infrastructure.
