Is Tap Water Safe to Drink in Portugal?

Can you drink the tap water in Portugal? Yes. Portuguese tap water is treated, regulated and safe to drink across the country. Here’s what it tastes like in different regions, how to order it in restaurants, and how to cut down on plastic bottles.

Quick answer: tap water is safe to drink throughout mainland Portugal, Madeira and the Azores. In some areas, especially parts of the Algarve, it can taste of chlorine, so many people prefer filtered or bottled water. Bring a refillable bottle. In restaurants, ask for “água da torneira” if you want tap water.

By region

• Lisbon and Porto: good quality and fine to drink.
• The Algarve: safe, but the taste is noticeably chlorinated in places.
• Madeira and the Azores: safe, often from mountain springs.
• Rural areas: mains water is safe. Avoid untreated springs or fountains marked “água não controlada” (untested water).

In restaurants

Restaurants usually bring bottled water, which you pay for. Ask for “água da torneira” (tap water) or “um jarro de água” (a jug of water). Some places will happily oblige, while others only serve bottled. Choose “natural” for room temperature, “fresca” for chilled or “com gás” for sparkling.

Reduce plastic

• Refillable bottle: fill up at your hotel and at public fountains marked as drinkable.
• Filter bottles: improve the taste where it’s chlorinated.
• Big bottles: if you prefer bottled, buy 5-litre bottles at the supermarket.

Staying hydrated

Summers are hot, especially inland and in the south. Carry water on hikes and sightseeing days. See healthcare for tourists.
