Is tap water safe in Dominican Republic?

Dominican Republic scores 41/100 on our water-safety index — drink with caution. Treated at the source, but aging distribution and storage can let quality slip. Many filter or drink bottled to be safe. 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

Dominican Republic relies on municipal treatment, variable upkeep, 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.
