Iran’s Capital Must Relocate Due to Dire Water Situation, President Insists

Mother Jones-Nov22,2025

Tehran is running out of water.

Rationing has begun in Iran’s capital city, with some of the approximately 10 million residents experiencing “nightly pressure cuts” between midnight and 5 am. The entire country is in an unprecedented drought, facing its driest—and hottest—autumn in nearly 60 years. Tehran has received no rain at all since the start of September, and no rainfall is expected for the foreseeable future.

The city depends on five major reservoirs for its water supply. One has dried up completely, with another below 8 percent capacity. The managing director of the Tehran Regional Water Authority told state media last week that the Karaj Dam has only two weeks of drinking water left. The drought extends beyond the city, too. The water reserves of Mashhad, the second largest city in the country, have dropped below 3 percent capacity, putting 4 million people at imminent risk.

But if nothing changes, Tehran may soon face Day Zero—or when a municipality can no longer supply drinking water to its residents and taps run dry. In October, President Masoud Pezeshkian claimed that Tehran could no longer serve as the country’s capital, citing the water crisis as a major factor.

”If it doesn’t rain in Tehran by late November, we’ll have to [formally] ration water,” Pezeshkian told Iranian state media on Thursday. “And if it still doesn’t rain, we’ll have to evacuate Tehran.”
