How Does Water Safety Work in Portugal?
Last verified: 2025-06 · Europe
1The Quick Answer
Tap water is safe to drink throughout mainland Portugal and on the islands of Azores and Madeira.
2What You Need to Know
Portugal's municipal water supply meets EU drinking water standards and is routinely tested. Tap water tastes fine in most areas, though some locals in Lisbon and Porto prefer bottled water for taste reasons rather than safety. The Azores and Madeira also have safe tap water, though mineral spring water from the Azores is a popular local choice. Restaurants will normally serve tap water if requested, and it is free.
3Practical Tips
Practical Tips
- 1Carry a reusable water bottle — tap water is safe everywhere and refilling it saves money and reduces plastic waste.
- 2Ask for 'água da torneira' (tap water) at restaurants; they are legally required to provide it free of charge.
- 3In the Algarve summer heat, stay well-hydrated — dehydration is a real risk for tourists unaccustomed to the temperatures.
