Health Risks for Travelers
Although residents may regularly consume the tap water without issues, travelers are often more susceptible to waterborne diseases due to differences in immunity and water treatment protocols. Contaminants that may be harmless to locals can cause digestive problems for foreign visitors.
Common health concerns include:
- Traveler’s diarrhea from unfamiliar bacteria like E. coli
- Parasites such as Giardia or Cryptosporidium, especially in untreated water sources
- Viral infections including hepatitis A and norovirus, often linked to poor sanitation
- Exposure to heavy metals or chemical pollutants in areas with inadequate water regulation
Risks are elevated in:
- Rural areas lacking centralized water treatment
- Flood-prone regions with compromised infrastructure
- Older buildings with neglected rooftop tanks or corroded plumbing
Even if the water appears clear, it may contain microbial or chemical contaminants that can lead to short-term gastrointestinal illness or more serious long-term health effects.
If you experience persistent symptoms while traveling in Taiwan, consult a local doctor or pharmacist. In many tourist areas, English-speaking care is available.
More About Tap Water in Taiwan

In eastern Kinmen, it’s made up of 50% imported water from China, 40% brackish water, and 10% desalinated seawater. While cities like Taipei, Taichung, and Tainan meet health standards, most residents still boil their tap water before drinking it due to concerns over aging pipes.
