Can you drink the tap water in Bengaluru?
Last reviewed September 2026 · India
Short answer: don't drink the tap water in Bengaluru untreated. At 35/100 it falls in the avoid band, so for drinking and brushing your teeth use sealed bottled water or a proper purifier, and treat ice and unpeeled salads in Bengaluru the same way.
Tap water for visitors to Bengaluru
In Bengaluru, treat drinking water as something you buy or treat, not something you pour from the tap. Use sealed bottled water for drinking and brushing, avoid ice unless you know it was made from safe water, and skip raw salads or unpeeled fruit rinsed in tap water. Hot, thoroughly cooked food and sealed drinks are the safe defaults.
If bottled water isn't to hand, a rolling boil for one minute or a purifier certified to remove bacteria and viruses will do the job — a plain taste filter won't. Untreated water in Bengaluru can carry the causes of travellers' diarrhoea and, in some areas, more serious infections, so it's worth checking your travel vaccinations before you go. See CDC food & water precautions.
