The various municipalities I've lived in require 5 to 8 feet minimum bury depth for water pipes to avoid freezing. The seasonal property I mentioned earlier being at 3-4 feet depth is likely helped by the fact that snow is not cleared above the run (additional insulation) and it is in one of the milder climate areas where a municipal spec water run would only need 5 feet of bury. It may also have half inch of foam wrap for insulation, I'm not sure. Agree on the pipe volumes.

That’s likely overly cautious. https://www.hammerpedia.com/frost-line-map/ https://www.hammerpedia.com/frost-line-map/ That said, municipality’s will often be overly cautious and they do need to consider property siting abandoned.

  > That’s likely overly cautious I'm not in the country shown on your map. The area of Canada I'm in would be somewhere roughly around the 90" line on that map. It's between the 2000 and 2500 lines on this map [1] (the seasonal property is around a 1500 contour) The municipalities pay for the main to be installed. They wouldn't spec it to be 8' (2.4m) deep if it didn't need to be. edit: the contours in my source are not mm of freezing depth, but degree-days of freezing. However, 2500 DDOF corresponds[2] with 70" of frost penetration, while the 1500 DDOF corresponds with 55". So the required bury depths are slightly but not significantly conservative [1] https://www.urecon.com/applications/images/canadian_map_lrg.jpg https://www.urecon.com/applications/images/canadian_map_lrg....

    I agree they need to bury it nearly that depth but while IPC 2018 section 305.4 puts water pipes at least six inches below the frost line many places increase that to 12” for water and or sewer. I don’t know much about how Canada does things.

      Yeah, you really don't want those sewer lines freezing...
