We just don’t drink much water, and people who do either buy mineral water or carry a bottle of tap or filtered water with them. It never really gets so hot that anyone is in dangr of dehydration.
Although there aren’t drinking fountains in Paris, there are lots of taps with drinkable water (eau potable) on the streets, you just have to bring your own bottle.
Yep, because all those people only drank booze because they were thirsty, not because their lives were crap…
Yup. You ask for tap water, and, just like in America, you get it free of charge. You ask for simple water, and you’ll get the bottled variety, usually sparkling (at least in most places I’ve been.)
DMarkActual water with actual ice, in Germany? I think I would have been in love!
The best tasting water in the world is from a spring on a hill in or near Heidelberg. We were shocked to not see “Kein Trinkwasser” on a fountain at the side of the road and then doubly shocked to see a family of Germans pull up and fill a couple large bottles. They even drank some right there. They told us to try and we did.
Germans, when I was there, were generally ticked off about pollution in water and did not think tapwater was pure enough to be safe. I watched the legislature in Bonn debate on water pollution and boy were they ever pissed off.
Yeah, but half of them will be broken, and half the remainder will have chewing gum and/or ketchup packets crammed into the nozzle. 
On my first trip to Paris, I learned to buy a large bottle of water the first day, then refill it from the hotel each morning, and carry it in my backpack.
They do have low faucets for dogs, though I wasn’t brave enough to refill my bottle from one of them.
In Vienna, I was surprised to find a water fountain at Schwarzenbergplatz. According to the plaque, the water came directly from a glacier in the Alps. It was the best I’ve ever tasted. And cold too.
