Aging network · frequent contamination pointsIs tap water safe in Indonesia?
Indonesia scores 33/100 on our water-safety index — not safe to drink. Largely unsafe straight from the tap. Filter, boil, or buy bottled — do not risk the raw supply. 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
Indonesia 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.
