That’s very interesting. Which communities? Does the hot water itself heat the buildings?

In Whitehorse, Yukon, the warm deep-well water is mixed in with the cold river water (the main water source) in the winter. It keeps the water from freezing in the water mains, and waste water from freezing in the sewers. In Mayo, Yukon (a much smaller community than Whitehorse), geothermal wells have been used to heat the town water, since the 1980s. Heat pumps are being added, to extract enough geothermal heat to heat municipal buildings.

Note, these are warm or hot-water geothermal sources (like the one mentioned in the article). They are very different from using geothermal wells to produce superheated steam, to generate electricity. These geothermal wells may be deep (not all are); but, they aren't more complicated than ordinary drilled-water wells. The water is just a bit warmer. OTOH, using geothermal heat to produce superheated steam is complex, and problematic in practice.
