Water Source
The Metropolitan Waterworks Authority (MWA) treats water to a reasonable standard at the plant, but aging distribution pipes and low pressure zones allow recontamination before it reaches taps.
Contaminants & Concerns
Bacterial contamination from pipe intrusion is the main concern, along with inconsistent chlorination in older neighborhoods.
Tips
- •Bottled water is sold everywhere for a few baht
- •Blue filtered-water refill stations are common and widely used and safe
- •Avoid ice from informal street vendors; factory-made ice with a cylindrical hole is generally safe
