Cambodia is a little confusing when it comes to the safety of tap water. Officially, the water running through the mains supply in Phnom Penh and Siem Reap is safe to drink. However, Cambodian buildings tend to have large storage tanks that mains water is pumped into before it reaches the tap. These tanks can be breeding grounds for a range of bacteria and viruses.
It’s always recommended to ask at your accommodation whether the tap water is drinkable. Newer buildings may not have storage tanks, although installing them is still a relatively common practice. Outside of Cambodia’s major cities, tap water should be avoided.
You may notice tap water in Cambodia has a distinct smell of chlorine which can also affect the taste. Chlorine is used as a disinfectant, so water that smells this way should be safe to drink, however, plenty of people don’t like the taste.
