Tap water in Switzerland

Generally safe to drink

The WHO and UNICEF put safely managed drinking water within reach of 95% of people in Switzerland. National figures describe a country, not the tap in front of you.

What the sources say

Numbeo

91.85/100 on the water drinkability and accessibility index, which Numbeo reads as “Very high”. This one is crowdsourced from residents rather than measured.

Lonely Planet

Tap water in Switzerland is pure, rich in minerals and perfectly safe to drink – in fact it's often just as good as any of the stuff you can buy in bottles. Don't necessarily expect it free in restaurants, however; bottled water (either still or sparkling) is the norm.

Safe nationally still means ask locally. Older buildings can carry lead or copper pipework, and a single street can differ from the network feeding it. If you are staying somewhere old, ask your host.

What bottled water costs you here

Drinking tap water instead of bottled would save one adult about 701$ a year in Switzerland, and keep several hundred plastic bottles out of circulation.
