Can You Drink Tap Water in Zurich?

Tap water in Zurich is completely safe to drink and is widely regarded as one of the best municipal supplies in the world. The city draws water from Lake Zurich, protected springs and groundwater, giving the system a diverse and resilient source base.

Lake water is treated through advanced multi-stage processes before entering the network, while spring and groundwater require less treatment because of their natural quality. Zurich's water utility monitors the supply continuously and applies strict Swiss drinking-water standards.

Visitors can drink from taps throughout the Altstadt, Enge, Zürich-West, Oerlikon, around Bahnhofstrasse and in hotels across the city. Internal plumbing in maintained buildings does not present a general concern. Run the cold tap briefly in an older room if water has been standing for many hours.

Zurich is famous for its public fountains. The city has more than a thousand fountains, and most dispense potable water unless clearly marked otherwise. They provide the same safe municipal supply and make carrying a reusable bottle especially practical.

The water is suitable for drinking, brushing teeth, cooking and making ice. Taste can vary slightly depending on whether the local blend contains more lake, spring or groundwater, but all sources are safe.
