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 Iran, consult a local doctor or pharmacist. In many tourist areas, English-speaking care is available.
More About Tap Water in Iran
Iran has a long history of water management using traditional methods like qanats, which channel groundwater from highlands to villages. Today, with renewable water availability dropping below 500 cubic meters per person per year, Iran is investing in technologies like reverse osmosis and desalination to meet growing demand. In rural areas, household-level purification systems are also being introduced to improve drinking water quality.
