Water Quality Details

Macau follows China’s drinking water regulations, with supply primarily from a mix of surface and groundwater sources treated by filtration, chlorination, coagulation/flocculation. While treatment is in place, quality can vary at the building level due to storage tanks or older plumbing, and this can affect taste and consistency. Visitors are generally advised to use bottled or properly filtered water for drinking and to be cautious with ice. If you need to use tap water, boiling for at least one minute provides an extra safety margin.
