Can I drink tap water in Sri Lanka?

No, it really is not safe for foreign travellers to drink tap water in Sri Lanka unless it has been boiled thoroughly and carefully filtered. If you can, you should stick to sealed bottled water or use a dependable water purification device, because that is the safer path overall.

In Sri Lanka, the municipal water supply sometimes carries bacteria and other microorganisms that many visitors’ immune systems are not used to, and this can lead to serious stomach problems. Even though locals may handle municipal water in some areas, tourists should depend on commercially purified bottled water only, which is widely sold at grocery shops, pharmacies, and hotels. Also, to reduce the chance of waterborne sickness as much as possible, do not accept ice in drinks at casual street food spots, and use bottled water even when you brush your teeth.
