Is tap water safe in Nigeria?

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. 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.

Drinking, brushing, ice & cooking

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.

Water treatment & pipe infrastructure

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.
