How Does Water Safety Work in Tanzania?
Last verified: 2025-06 · Africa & Oceania
1The Quick Answer
Never drink tap water anywhere in Tanzania — bottled or filtered water is essential, and purification tablets are necessary for remote trekking.
2What You Need to Know
Tap water throughout Tanzania including in tourist hotels in Dar es Salaam and Arusha is not safe to drink without treatment. Most lodges and safari camps provide filtered or bottled water; confirm this on arrival and never assume tap water in your room is safe. On the Kilimanjaro ascent, streams and mountain water sources must be treated with purification tablets or a filter as they can be contaminated by other trekkers upstream. Cholera outbreaks have occurred historically in parts of Tanzania and remain a risk in areas with poor sanitation. Ice in drinks at non-tourist establishments may also be made from tap water.
3Practical Tips
Practical Tips
- 1Carry a Lifestraw or SteriPen water purifier for Kilimanjaro trekking — it reduces plastic waste and ensures you can treat water from mountain streams safely.
- 2Ask your lodge or camp explicitly whether drinking water provided is bottled or filtered — most reputable establishments use filtered dispensers to reduce plastic.
- 3Avoid salads, raw vegetables, and ice in drinks at local restaurants where hygiene standards are uncertain.
Important Warning
Tap water in Tanzania is not safe to drink under any circumstances — even brushing teeth with tap water can cause illness in travellers without local immunity.
