We already changed enough to survive at below -50 and know, that plumbing in a single family home in this climate is... hm... questionable...
Oh, I thought you're still dreaming about sending Poles to Kolyma :)))
OK then:
There will be good science paper theme for someone - supporting of internal plumbing of individual home and external communications at temperatures below -50 deg C.
How about this?:

"The quick answer is that freezing temperatures only penetrate a certain distance into the ground. This is called the "frost line". Water and sewer lines are buried below the frost line, and also enter the house below this line as well. In my location (Toronto) most water lines are about 5 or 6 feet deep.
This is also a problem within the house. In cold climates, plumbing must never be run in an outside wall, because it can and will freeze. Contrast this with, say, England, where waste plumbing is often outside the house.
Now, in the Arctic they have the opposite problem: the ground is permanently frozen (see Permafrost). In this case, lines are run in heated enclosures on top of the ground"
Let's name it "patient-oriented technologies in modern jurisprudence".
Yeah, yeah, whatever - I'm still waiting for that long list of "desecrated" graves of Soviet soldiers in Poland :)
