Switzerland doesn’t have many natural resources (unless you count gorgeousness), but it does seem to have a healthy supply of clean water. Zürich has over 1,200 drinking fountains, and the styles vary. If you don’t have your water bottle with you, just stick your mouth over the endlessly running stream of clear water.
From modern art
To the more Classical
Spewing animal heads
Artful versions in the cemetery
Statues (this one is in Schaffhausen)
And most fountains seem to have a place for your pooch to quench his thirst, too.
