We have similar problems in Montreal because some pipes are 100 years old, but in well-made installations buried deep enough no problem if it is -25 and then it goes to +2 sometimes in two days, it does not bother
What we notice when the earth is well covered with snow there is less problem whatever the temperature.
Send your engineers to do an internship in cold countries
In the future you will have to learn to adapt to the cold. It's just a question of organization and foresight

Most of the pipes that jump are between 75 and 100 years old so no internship is needed !!!
