Tap Water Safety in Switzerland

Can you drink the tap water in Switzerland?

In general, yes.

The US Center for Disease Control’s travel advisory confirms the safety of the tap water in Switzerland (source). However, it would be best if you take special precautions toward the unregulated water sources in some areas.

Like all countries though, water accessibility, sanitation, and treatment vary widely from location to location, so we encourage looking for specific city information.

What do people in Switzerland think about the tap water?

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.


Generally there is no problem with food and water in Switzerland. Restaurants are controlled by strict rules. Water is perfectly drinkable everywhere from literally every water tap, even out of all public fountains unless specially marked (Kein Trinkwasser! - Pas potable! - Non potabile!). There are many organic food stores and restaurants available and it is currently illegal to import or sell any genetically modified food.
