Health Risks for Travelers

While locals may drink the tap water with no issues, tourists often face a higher risk of stomach infections and digestive upset due to unfamiliar microbes and variable water quality standards.

Watch out for:

  • Traveler’s diarrhea from bacteria like E. coli
  • Waterborne parasites like Giardia and Cryptosporidium
  • Viruses such as norovirus or hepatitis A in areas with low hygiene standards
  • Potential chemical contamination from outdated pipes or industrial runoff

Risk factors include:

  • Remote or underdeveloped regions without water purification
  • Urban areas hit by flooding or water service interruptions
  • Hotels or apartments with old plumbing or poorly maintained water tanks

Even if tap water looks clean, it could still carry invisible threats. To avoid gastrointestinal illness while traveling, it’s best to err on the side of caution.

If you experience persistent symptoms while traveling in Hong Kong, consult a local doctor or pharmacist. In many tourist areas, English-speaking care is available.

More About Tap Water in Hong Kong

Hong Kong runs a high-tech water treatment system, with 20 treatment plants and one desalination facility. Water goes through chemical dosing, clarification, filtration, and disinfection, with a small amount of residual chlorine left in to keep bacteria from growing during distribution. To save freshwater, Hong Kong also uses seawater for flushing toilets—this accounts for about 23% of total water use.
