Iran’s water industry officials warned on Saturday that rationing in Tehran began far too late, as the capital’s water situation deteriorates rapidly amid one of its driest periods in nearly fifty years.
The city’s water resources are in exponential decline, Reza Haji-Karim, head of Iran’s Water Industry Federation, told the website Didban Iran.
“Water rationing should have started much earlier. Right now, 62 percent of Tehran’s water comes from underground sources, and the level of these aquifers has dropped sharply.”
The crisis, he said, is the result of years of neglecting scientific warnings about groundwater depletion and climate change.
“The only way to save Tehran is through a chain of measures – from wastewater recycling and consumption reform to cutting agricultural water use,” he added.
Unannounced rationing begins
Residents of Tehran have reported repeated overnight water cuts in several districts in recent days. The Tehran Water and Wastewater Company said the outages are intended to refill storage tanks and prevent the city’s distribution network from collapsing.
Local media outlets reported that nightly rationing has already started in parts of the capital and now continues until early morning hours.
The government may be forced to reduce water pressure to almost zero at night when demand is low, Energy Minister Abbas Aliabadi said Saturday, urging households to install storage tanks.
"Pipeline infrastructure in our country is more than 100 years old; the pipes have become worn out, and some of them were also damaged during the 12-day war" with Israel in June, the minister said.
Presidential warning and vanishing reserves
President Masoud Pezeshkian warned on Thursday that if rainfall does not resume by the end of autumn, Tehran will face water rationing, adding, “If it still doesn’t rain, we will have no water and will have to evacuate the city.”
The Tehran Regional Water Company has said that the capital’s five major dams are now only 11 percent full.
Ali Shariat, secretary-general of the Water Industry Federation, blamed the deepening crisis on “mismanagement and fragmented decisions in agriculture and industry.”
“My honest advice to the public is to take the president’s words very seriously. He has told the truth – bitter but undeniable,” he added.
“Continued inaction may lead to forced migration from Tehran,” Shariat added.
Dams near collapse
A video posted on social media on Thursday showed the dry bed of the Latian Dam near Tehran, whose manager said only half of its remaining 10 percent capacity can be used. Officials in neighboring Alborz province reported that the Karaj Dam is now more than 90 percent empty, with only seven percent of its reservoir remaining.
Tehran, home to nearly nine million people, depends on five dams – all reporting sharp declines.
The Laar and Mamloo reservoirs are at 1% and 7% capacity respectively, while only Taleghan remains above one-third.
This comes as the meteorological organization forecasts no significant rainfall for the rest of November.
Tehran is experiencing one of the driest periods in the past 50 years, according to the energy ministry. If current trends persist, officials warn, the city may run out of drinkable water within weeks.
