Complete Drinking Water Safety Information for Tanzania
Tap water in Tanzania is not safe to drink. Even in major cities like Dar es Salaam and Arusha, water treatment infrastructure is inconsistent and tap water may be contaminated with bacteria, parasites, or chemicals. Bottled water is widely available and strongly recommended for all visitors.
Bottled Water in Tanzania
Bottled water is widely available across Tanzania including Dar es Salaam, Arusha, Zanzibar, and most safari lodges. Popular brands include Kilimanjaro and Sayona. Budget roughly 1,000–2,000 TZS (USD $0.40–$0.80) per litre. Safari operators typically include drinking water in their packages — confirm this with your operator before departure.
Is ice safe in Tanzania?
Ice should be avoided throughout Tanzania unless you are certain it was made from purified or bottled water. In upscale hotels and safari lodges this is usually safe, but in local restaurants and street food settings, request drinks without ice as a precaution.
Can you use a water filter in Tanzania?
A quality portable filter rated for bacteria and protozoa is strongly recommended for extended travel in Tanzania, particularly on Kilimanjaro treks, remote safaris, and rural areas where bottled water resupply is limited. Filters do not remove viruses, so combine with purification tablets for full protection in remote settings.
Should you boil tap water in Tanzania?
Yes, boiling is essential if bottled water is unavailable. Bring water to a rolling boil for at least one minute. However, bottled water is widely available throughout Tanzania including in tourist areas, Zanzibar, and most safari destinations, and is always the safer and more practical option.
Questions!
Is tap water safe to drink in Tanzania?
No. Tap water in Tanzania is not safe to drink for visitors. Contamination with bacteria, parasites such as Giardia and Cryptosporidium, and chemical pollutants is common across urban and rural areas alike. Stick to sealed bottled water or use a quality filter.
Can I drink tap water in Dar es Salaam?
No. Despite being Tanzania's largest city, Dar es Salaam's water supply is unreliable and often contaminated. The city's aging infrastructure and rapid population growth have outpaced water treatment capacity. Bottled water is the safe choice for all visitors.
Is water safe on Zanzibar?
Not directly from the tap. Zanzibar's water supply relies on a combination of groundwater and treated surface water, but quality is inconsistent. Most hotels and resorts provide filtered or bottled water for guests. Confirm with your accommodation before drinking anything from the tap.
What about water on safari in Tanzania?
Reputable safari operators and lodges provide safe bottled or filtered drinking water for guests throughout the trip. Do not drink from rivers, streams, or any untreated natural water sources in the bush. Carry a portable filter or iodine tablets as a backup on extended expeditions.
What is the safest way to stay hydrated in Tanzania?
Drink sealed bottled water from reputable brands. Use a quality filter rated for bacteria and protozoa for longer stays or remote travel. Avoid ice in drinks unless you know it was made from purified water, and use bottled water for brushing teeth as well.
