Is tap water safe in Cuba?

Cuba scores 40/100 on our water-safety index — drink with caution. Safe in some areas, risky in others — closer to a coin-flip. Filter it, or reach for bottled when you are unsure. 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?
Generally okay, since a rolling boil kills most pathogens; rinse raw produce with filtered water when you can.

Water treatment & pipe infrastructure

Cuba relies on standard filtration + chlorination, delivered through a mixed network — aging mains in places. That puts the practical contamination risk between source and tap at medium. Even where water leaves the plant clean, aging mains and rooftop storage are where quality most often slips.
