Iran’s Capital Must Relocate Due to Dire Water Situation, President Insists
This story was originally published by Vox and is reproduced here as part of the Climate Desk collaboration. 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.” (Update: On Thursday, Pezeshkian president again said the capital will need be moved.) While it’s unlikely evacuation will happen any time soon, Tehran’s water crisis is not made equal. When the taps run dry, more affluent Tehranis purchase mineral water or rely on water tankers, a prohibitively expensive option for many. The rest must rely on charity, or they will die of thirst. Water use in Tehran is quite high, even for cities. But Iran’s water problems go deeper than this record-breaking drought. The country is uniquely isolated and subject to numerous sanctions, crippling the economy and making it very difficult for Iran to obtain state-of-the-art water technologies. It’s an enemy state to many of its neighbors, as well as regional leaders in desalination technology—Israel, Saudi Arabia, and the United Arab Emirates. But desalination is largely irrelevant in an Iranian context, often coming at a high environmental cost. According to water issues analyst Nik Kowser, Iranians are under the thumb of a “water mafia”—a shadowy and well-connected network driving these megaprojects for their own gain. “Iran faces water bankruptcy, with demand far outstripping supply,” Kowsar wrote in Time. “The collapse of water security in Iran has been decades in the making and is rooted in a mania for megaprojects—dam building, deep wells, and water transfer schemes—that ignored the fundamentals of hydrology and ecological balance.” Trying to relocate 10 million people would be an incredible logistical challenge. Iran is also particularly vulnerable to the effects of climate change: Over 82 percent of the country is arid or semi-arid, and Iran is sixth on the list of countries most prone to natural disasters. The country grows thirsty crops, and its quest for food security and self-sufficiency is a tremendous driver of its water bankruptcy. The agricultural sector comprises up to 90 percent of the country’s total water withdrawals.

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.
