Countries Where You Can Safely Drink Tap Water

Countries where tap water is generally safe to drink

The countries below are currently marked Safe in our country guides. This means the public supply is generally treated and considered suitable for drinking in the main cities and normal tourist areas. It does not mean the water tastes the same everywhere, or that a local boil-water notice can be ignored.

Large countries, remote communities, islands and buildings with private tanks can have exceptions. The links below open the full country guide, where those differences are explained in more detail.

Europe has the largest group of safe tap water countries

Across much of Europe, travellers can drink tap water directly from hotel and apartment taps. Our safe guides currently include Austria, Croatia, Czech Republic, France, Germany, Greece, Hungary, Iceland, Ireland and Italy.

The list also includes the Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland and the United Kingdom. In cities such as London, Paris and Rome, bottled water is usually a matter of taste or convenience rather than safety.

Some European guides still contain local cautions. Smaller Greek and Croatian islands may rely on desalination or tanker deliveries. Rural properties in Ireland, Romania or Hungary may use private wells, while old building pipes can affect water after it leaves the public network. Check the full guide for the exact place you are staying.

Australia, New Zealand, Japan and Singapore

Tap water is safe across the main public systems in Australia and New Zealand. Major destinations such as Sydney and Melbourne have closely monitored supplies, and carrying a reusable bottle is the easiest option for most visitors.

In Asia, Japan and Singapore stand out for reliable public drinking water. Visitors can drink from hotel taps in Tokyo, use public fountains and accept ice in restaurants without special precautions.

Remote areas can still use a different source. Some Australian outback properties and New Zealand rural accommodation rely on bore water, rainwater tanks or private systems. Ask locally when staying well outside a town connected to a municipal supply.

Canada, the United States and safe Caribbean destinations

Canada and the United States have safe tap water across most cities and towns. Local exceptions include private wells, older buildings with lead plumbing and communities under a temporary or long-term advisory. A national Safe rating should never replace a current notice for the exact area.

Several Caribbean destinations are also marked safe: Aruba, Barbados, the Cayman Islands, Puerto Rico and Turks and Caicos. Aruba and the Cayman Islands use desalination to produce reliable drinking water, while Barbados benefits from treated groundwater.

Outer islands and rural areas can differ from the main resort zones. In Puerto Rico, Vieques or Culebra may use different infrastructure, while less developed islands in Turks and Caicos can rely on tanks, wells or rainwater. Confirm the supply with the accommodation before drinking it.

Safe tap water in the Middle East often comes from desalination

The safe list includes Bahrain, Israel, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates. Much of the Gulf depends on desalinated seawater that is treated to drinking-water standards before distribution.

The main caution is often the building rather than the treatment plant. Water may pass through rooftop or basement storage tanks before reaching a hotel room or apartment. Poorly maintained tanks can affect taste or quality, which is why many residents still prefer bottled or filtered water even where the municipal supply is marked safe.

In major hotels and established restaurants, ice and food preparation normally use treated water. In remote desert camps, mountain villages or properties using a private source, ask where the drinking water comes from instead of assuming the city advice applies.

Chile and Uruguay in South America

Chile and Uruguay are the South American countries currently marked safe in our guides. Santiago, Montevideo and the main tourist cities have treated public supplies that visitors can generally drink.

Chile is long and geographically varied, so the advice for Santiago does not cover every remote desert property, Easter Island or isolated Patagonian lodge. Uruguay is more consistent, although remote estancias may use private well water. Open the individual guide when travelling beyond the main urban network.

What a Safe rating means for your trip

A Safe rating means travellers can normally drink the public tap water in the country’s cities and established tourist areas. It also generally means the water is suitable for brushing teeth and that ice at reputable venues is made from a treated supply.

It does not remove the need to check local advisories, building plumbing or private water sources. After flooding, a burst main or treatment failure, one town can receive a warning while the rest of the country remains unaffected. Hotel storage tanks can also make room tap water different from the city supply.

Start with the country guide, then check the relevant destination guide and any current local notice. That gives a more useful answer than relying on a country name alone.
