Last reviewed September 2026
Nigeria scores 27/100 on our water-safety index — not safe to drink. Not safe from the tap. Water should be boiled, filtered, or bottled before you drink it. So when people ask whether tap water is safe in Nigeria, the honest answer is “not safe to drink.” Scores above 70 mean tap water is generally safe to drink. 40–69 means treat it with caution — filtering or bottled water is wise. Below 40 means it’s best avoided straight from the tap.
Ice, brushing your teeth & cooking: what’s safe in Nigeria?
- Drinkable?
- No — don’t drink it unfiltered. Boil, filter, or buy bottled.
- Brush teeth?
- Risky — use bottled or boiled water to brush, especially for children.
- Ice?
- Avoid ice — it’s frequently made from untreated water.
- Cooking?
- Boil first — water that reaches a full boil is far safer than raw tap; don’t rinse salad or fruit in it.
Should you boil the tap water in Nigeria?
If you have to use the tap water in Nigeria, boil it first: a rolling boil for one minute makes it microbiologically safe to drink. Boiling does not remove chemicals, heavy metals, or lead, so filtered or bottled water is better where you can get it. More on what boiling does and doesn’t remove.
Do you need bottled water or a filter in Nigeria?
Bottled water is the safest choice for drinking in Nigeria, and it's widely sold — always check the seal is intact before you buy. A reusable bottle with a built-in purifier cuts both cost and plastic waste on longer stays.
A basic taste filter won't make the tap water in Nigeria safe. If you filter, use a purifier certified to remove bacteria and viruses; otherwise rely on bottled or boiled water.
Waterborne illness risk in Nigeria
Untreated water in Nigeria can carry the organisms behind travelers' diarrhea and, in some areas, more serious infections such as typhoid and hepatitis A. The CDC advises drinking only bottled, boiled, or properly filtered water, and checking your routine and travel vaccinations before you go. See CDC food & water precautions.

Water treatment & pipe infrastructure in Nigeria
Nigeria relies on limited treatment, aging network, delivered through a aging network — frequent contamination points. That puts the practical contamination risk between source and tap at high. Even where water leaves the plant clean, aging mains and rooftop storage are where quality most often slips.
Tap water safety by city in Nigeria
Water quality is rarely uniform. In Nigeria, notable variation includes Lagos at 24/100.

Data & sources
Official monitoring (WHO/UNICEF JMP, 2024) puts safely-managed drinking water access in Nigeria at 29.9%. Access to a safe source isn’t the same as tap-drinkability for visitors — our 27/100 score weights traveler drinkability, informed by this data.
