Is Hanoi Tap Water Safe To Drink?
No, it's not advisable to drink the tap water.
Tap water in Hanoi is treated to meet Vietnamese drinking water standards, but it is generally not recommended to drink directly from the tap. Aging pipes, building storage tanks, and local contamination can affect water quality after treatment.
Drink bottled water or use a properly maintained filter, especially for children, older adults, and people with weakened immune systems. Boiling tap water before drinking provides additional protection, but it does not remove chemical contaminants.

Source of Water in Hanoi, Vietnam
Hanoi’s tap water comes mainly from treated surface water drawn from the Da River and the Duong River, a branch of the Red River. The city also uses groundwater from wells to supplement these supplies.
Water is processed at plants such as the Song Da and Duong River facilities before entering Hanoi’s distribution network. The exact source mix varies by district and local water company.
Hanoi Drinking Fountains
Public drinking fountains in Hanoi are not generally considered reliably safe for drinking. Water treatment standards may be adequate, but fountain cleanliness, filter maintenance, and distribution pipes can affect quality.
Use bottled water or water from a properly maintained filtration system instead. If no alternative is available, boil the water before drinking.
