Having water pipes in the ground isn't inherently bad. And why does having 70km of them affect anything? Your tap water comes from a much larger system of underground pipes, for example.

The footprint of ski resorts is not that large, even though they're in ecologically important places. I'm really struggling to understand the impact of these places. If you want clean water, then clean the water. If you want non-polluting power, then do that. Why is a ski resort responsible for any of this?
