Source of Water in Tehran, Iran

Tehran's tap water mainly comes from surface water sources, including the Lar and Karaj dams. These reservoirs supply the majority of the city's water.

Additionally, groundwater wells supplement supply, especially during dry seasons or high demand periods. Groundwater accounts for a smaller proportion of the total water.

Water is treated at municipal treatment plants before distribution to ensure safety and quality for urban consumption in Tehran.

Tehran Drinking Fountains

Public drinking fountains in Tehran may not always meet strict hygiene and water quality standards. Their safety can vary based on maintenance and source water quality.

Users should exercise caution, especially vulnerable individuals. Bottled or filtered water is generally recommended over public fountains for drinking.

Local health authorities advise regular cleaning and monitoring, but inconsistent practices mean reliability cannot be guaranteed city-wide.
