Source of Water in Bangkok, Thailand

Bangkok's main tap water sources are the Chao Phraya River and the Mae Klong River, supplying raw water for treatment plants.

Several water treatment plants process river water, removing contaminants before distributing it to the city’s tap water system.

Groundwater is minimally used due to limited availability and quality concerns, with surface water being the primary source.

Bangkok Drinking Fountains

Public drinking fountains in Bangkok vary in safety depending on maintenance and water source quality.

Many fountains use treated tap water, but hygiene and contamination risks can occur due to exposure and lack of regular cleaning.

It is generally safer to use bottled water or personal filtered water rather than relying on public drinking fountains.
