The Short Answer: It's Best to Avoid
While tap water in many of Turkey's major cities, such as Istanbul and Ankara, meets international safety standards at the treatment plant, the journey to your tap is where the risk lies. For travelers, sticking to bottled or filtered water for drinking is the safest and most widely recommended option to prevent potential stomach issues. This is the consensus among both tourist guides and a majority of locals who also prefer bottled water for their daily consumption.
Why Tap Water in Turkey is Risky for Travelers
Inconsistent Water Quality and Infrastructure
Turkey's water infrastructure varies significantly by region. While large urban centers have modern treatment facilities, water quality can be affected by agricultural runoff, industrial pollutants, and differing regional standards. Aging pipes and potentially unclean rooftop storage tanks in older buildings can also introduce contaminants.
Traveler's Stomach and Acclimation
A traveler's digestive system may react to differences in mineral content or unfamiliar bacteria in local water, even without significant contamination, leading to gastrointestinal distress. Locals, having developed resistance, may not experience the same issues. This makes bottled or purified water a wise choice for visitors.
Safe Alternatives for Drinking Water
Ensuring safe hydration in Turkey is easy and affordable with these reliable methods:
- Bottled Water: Widely available and inexpensive, bottled water is the most popular option. Always check for an intact seal. Large 'damacana' jugs can be delivered for longer stays.
- Filtered Water: Portable filters or filter bottles are an eco-friendly way to remove bacteria, parasites, and some chemicals. Many modern establishments also offer filtered water.
- Boiling Water: Boiling for at least one minute (three at high altitudes) kills microorganisms. However, it does not remove chemical pollutants or heavy metals and can concentrate contaminants as water evaporates. Use only if other options are unavailable.
Comparison: Tap Water vs. Bottled Water in Turkey
| Feature | Tap Water | Bottled Water |
|---|---|---|
| Safety for Travelers | Not Recommended | Highly Recommended |
| Risk Factors | Inconsistent quality, old pipes, storage tanks, mineral content. | Low to None (check seals) |
| Cost | Very Low | Very Low (often just 1-5 Turkish Lira for a small bottle) |
| Availability | Available everywhere, but safety varies. | Readily available everywhere from shops to hotels. |
| Taste | Can have a chalky or chlorinated taste. | Neutral, clean taste. |
| Environmental Impact | Lower plastic waste if pipes are safe. | Contributes to plastic waste. |
A Note on Using Tap Water for Cooking
Using tap water for cooking or washing produce is generally acceptable, especially in major cities, as cooking kills microbes. Some people prefer bottled water for washing vegetables and brushing teeth for extra safety. Restaurants in tourist areas typically use filtered water for ice.

Conclusion: Making the Safest Choice
Despite potential treatment at the source, variable infrastructure and quality make direct consumption of tap water risky for travelers in Turkey. Readily available and affordable bottled water is the safest and most convenient option for drinking and brushing teeth. While tap water is generally fine for tasks like showering and cooking, choosing a purified alternative for consumption is recommended for a healthy trip.
