Iran
Tap water situation
In Iran, the safety of drinking tap water can vary considerably across different regions. Generally, in major cities like Tehran, Shiraz, and Isfahan, the tap water is considered safe to drink due to regular treatment and monitoring by local authorities. However, in smaller towns and rural areas, the water quality is less reliable, and it is often recommended to use filtered or bottled water to avoid potential health risks. The Ministry of Energy is the government body responsible for managing and ensuring the quality of water supplies across Iran. They oversee the national water and wastewater policies to maintain safety standards.
