Thailand
Tap water situation
Tap water in Thailand is generally not considered safe for drinking directly. Many locals and travelers opt for bottled water or filtered options due to concerns about waterborne contaminants. In urban areas, water treatment facilities do exist, but inconsistencies in infrastructure and maintenance can affect water quality. The responsibility for water quality in Thailand falls under the Metropolitan Waterworks Authority and the Provincial Waterworks Authority, which manage water distribution and quality in different regions.
