Can I drink tap water in
Brunei?

Tap water in Brunei is treated to high standards and generally safe in Bandar Seri Begawan and main towns — many locals still prefer boiled or bottled.

Yes — brushing teeth with tap water in Brunei is generally safe.

In reputable city restaurants and hotels, ice is usually made from filtered or bottled water. Outside cities or at street vendors, ice may be made from tap water — ask before ordering.

Boiling water for at least one minute kills most pathogens, so hot tea and coffee made from properly boiled water are generally safe even where tap water isn’t. Be cautious of warm drinks that may not have been brought to a full boil.

A reusable bottle plus optional filter is sensible — tap is fine in cities and treated supplies, and a filter covers you for rural or older-building situations.
