Question: Can I Drink the Water in Hong Kong?
Answer: Water in Hong Kong from the tap is generally considered safe to drink, although it should be boiled beforehand. The water in Hong Kong is filtered through a system which matches that of the US and Western European countries. That said, some of the pipes in Hong Kong are old and corroded, which can cause the water to have an unpleasant, often metallic taste.
Most Hong Kongers drink bottled water and if in doubt, so should you. You should certainly steer clear of ice cubes, as these may not have been boiled, and only order bottled water in restaurants.
