The water quality is superb --- better than most bottled water, they say --- and they run off their own distribution network, which means the water fountains operate as the emergency backup for if the main distribution network goes down. They run continuously, too. Ah, here we go. (People are really keen on Zürich's water fountains. You can get guided tours.) https://zurich1200fountains.wordpress.com/ https://zurich1200fountains.wordpress.com/
