January is not like September
This is Calgary's own water main break data, every break recorded from
2015 to 2025, grouped by month. Nobody in the industry needs telling that
winter is worse — but the size of the gap is worth seeing.

January 301 breaks, September
108 — the peak and the trough, roughly
2.8×. Those two are the figures we verified; the
months between are drawn to shape, not to the decimal. Source:

Two things make that worse than the chart looks.
Calgary's frost line reaches two to three metres and water pipes sit at
three to four, so the ground itself fights you on every winter repair. And
the city's own frozen
pipes program runs December 1 to March 31 — a four-month window when
your phone rings hardest and you have the least slack to answer it.
Then it flips. High river flow season is
May 15 to July 15,
and the calls change from frozen to flooded. Different problem, same
phone, still ringing while you're under someone's basement.
