Calgary loses billions of litres of drinking water a year due to leaks, according to a new report.

The report from the City of Calgary indicates that 22 per cent of its water was lost in 2022 — and 88 per cent of it was because of water leaks.

The unaccounted for water that year alone equates to approximately 31.6 billion litres. In Edmonton, only 5 per cent of the city’s water was lost from leaks in 2022, according to the same report.

The CEO of Build Calgary says he’s been writing the city about the problem for some time and highlighted the number in a recent letter.

Sounds like they're already very aware of this.

KLASZUS: As our drop makes its way through Calgary’s pipes, it may or may not make it to your tap, because of leakage. And leakage is normal in municipal water systems. Calgary loses somewhere in the realm of 20% of its treated water through leakage—but this isn’t entirely unusual.

BLACK: Everyone compares this to oil and gas. In an oil and gas leak, you’d have a response right away. You’d be monitoring the health and safety of the pipe. When oil leaks into the environment, it’s kind of a big deal. But when water leaks into it, no one necessarily thinks of that as a bad thing, because it’s just going back into the environment. So there’s not as much of a concern around leaky pipes, but we definitely have leaky pipes. And it’s a hard thing to estimate. These are all estimates, if it’s 20%, whatever, those are estimates of how much you’re losing in the system.

Across Canada, we're probably looking anywhere from 5%, 10% leakage to some communities having upwards of 50%, 60%. It really varies, and certainly if you spend more time operating and maintaining and inspecting your pipes then you're able to stay on top of that. But it's something that we accept. There's a certain amount of of water leakage within a distribution system that you are okay with, and sometimes, depending on the city, 20%, 30%, 40% they might be okay with.
