We're in Nuuk, the capital of Greenland with a population of around 16,000 people ! This is a place that gets seriously cold, as you can imagine. Even the summer, when I was there, wasn't that warm....for us ! So the services to the houses are kept simple and protected. The electrics run in a pipe, and the drainage (dark matter and grey matter to be polite) are simply gravity fed into the closest convenient place. This is sometimes a tank and sometimes the sea. Oh well, it works.
