We have clean water in Austria, directly from the mountains without adding anything (just cleaning it with UV light to kill potential bacteria in most regions, nothing else. Not even that in some regions).

Some of the best and cleanest water worldwide, so whenever I go to another country I’m disappointed by their water quality.

Clean and well-tasting tap water. It sucks when I’m going to another country and they have chlorinated tap water

In Austria we say “Sudern auf hohem Niveau”

Yes, compared to other countries Austria is very good. But things could still be much better.

I guess they might be appropriate for some roads (in poor or very rural countries)

But not here
