A senior Iranian water expert warned on Sunday that the country’s central plateau could be emptied of inhabitants if authorities fail to address the worsening water crisis, as officials in Tehran admit that rationing in the capital began too late to avert shortages.
Ali Moridi, head of the Water, Wastewater and Environmental Engineering Department at Shahid Abbaspour University of Water and Power Industry, said Iran’s water emergency stemmed not only from its arid climate but from a chronic disconnect between scientists, industry, and government agencies.
“If the current situation continues, it is not unlikely that Iran’s central plateau will become depopulated,” Moridi told reporters at a university briefing.
Moridi cited research linking groundwater depletion and soil salinity to rural migration in southern provinces such as Fars, where vanishing wells have pushed villagers toward cities, worsening urban sprawl and social pressures.
“Many rural communities with high migration rates were directly affected by falling groundwater levels and the salinization of drinking water,” he said.
He urged stronger cooperation between academia and policymakers and showcased a new university-led “biochar” project that converts agricultural waste into a soil additive capable of reducing water use in farming – a sector that consumes over 80 percent of Iran’s water.
“The project must move from the lab to the field,” he said. “Reducing agricultural water use is vital if Iran is to survive this crisis.”
Nationwide emergency
Moridi’s comments come as Tehran faces unannounced nightly water cuts, with reservoirs at record lows and drought conditions worsening across 20 provinces.
The Karaj Dam, one of the capital’s main suppliers, has dropped to less than 10 percent of capacity, officials said this week.
Energy Minister Abbas Aliabadi said on Saturday that some of the city’s pipeline infrastructure was “over 100 years old and severely damaged,” forcing the government to cut nighttime supply to prevent network collapse.
President Masoud Pezeshkian warned earlier this week that Tehran could face mass evacuation if the drought persists through winter. “If it doesn’t rain, we will have no water,” he said.
Meteorologists say the country has entered one of its driest 50-year periods, with rainfall down more than 85 percent compared with last year.
The National Drought Crisis Center has classified the situation as “severe,” warning that no significant rain is forecast for at least ten days.
“Almost all underground and under-mountain missile infrastructure remains intact and has no serious problems,” Gholamreza Jalali said, crediting long-running operational measures and engineering choices.
The priority given to aerospace and missile assets, Jalali said, guided 20 years of planning for missile cities and depots built into mountains and deep underground. Only minor repairable damage occurred at some access points, he added.
Underground networks and nuclear sites
Sensitive nuclear centers, Jalali said, were placed in safe spaces after early threat assessments, adding that he personally proposed the protected design concept years ago.
“The shadow of war was present from the very beginning of our activities, and based on the threat scenarios, it was decided that sensitive nuclear sites should be designed in secure underground locations beneath mountains.”
During the 12-day war and the US attacks on nuclear facilities, added Jalali, some foreign reports highlighted the confrontation between “bunker buster bombs” and Iranian concrete engineering. “It was an oversimplified interpretation of designs."
“Regarding the US claim of destroying nuclear facilities, it must be said that further details remain classified and confidential,” he added.
Banks cyber security not addressed yet
Jalali pointed to cyber-attacks on Iranian banks, saying two major banks shared a core platform with unresolved weaknesses. “For banking security, we designed a regional secure model and obtained funding, but execution rests with the relevant bodies,” he said.
During the June conflict, Iran’s Bank Sepah and Bank Pasargad were hit by major cyberattacks that disrupted online banking and ATM services.
Jalali also addressed the use of foreign messaging platforms by military figures, saying none of Iran’s commanders, living or dead, had ever used WhatsApp, while reports suggested some Hamas leaders had relied on it.
Advanced surveillance and data-analysis systems – spanning artificial intelligence, satellites, and signal tracking – are fully controlled by Israel and the United States, he said, adding that using such platforms exposes communications to monitoring and targeting.
“When we are in confrontation with such adversaries, we must assume total visibility across digital space.”
Former communications minister Mohammad Javad Azari Jahromi said in August that Iranian officials with sensitive information on their phones were easy targets for Israeli cyber operations during June's 12-day war, adding that Israel exploited platforms such as WhatsApp to track them.
“In the recent war, those who had information and were of interest to Israel were easy prey for hacking,” Azari Jahromi said, but did not identify those targeted.
Shelters kept confidential
Tehran has multiple shelter options, including metro stations, car parks, and basements, but officials avoided announcing them publicly to prevent panic, he added.
Local authorities received training to guide people in emergencies, while Tehran Municipality was working to upgrade facilities and warning systems for possible use as public shelters, according to him.
Iran had fully expected attacks on its nuclear facilities and launched a plan to prepare, he added.
Limited drills in Kashan and broader exercises at Fordow, Natanz, and Isfahan helped minimize risks, Jalali said, adding that chemical storage was cleared and activities scaled back before strikes, and post-attack tests confirmed no radioactive contamination.
The dissident activist made the remarks in Berlin on the sidelines of the annual forum of the World Liberty Congress, a movement she co-founded in 2022 along with Russian activist Garry Kasparov and Venezuelan opposition leader Leopoldo López.
“We intend to increase pressure on dictators by uniting opposition movements from different countries," she said.
Alinejad compared Iran’s compulsory hijab laws and political repression to the Berlin Wall, telling Iran International that Iranians are destroying this wall through their defiance.
The World Liberty Congress is holding its second annual gathering on the sidelines of the Freedom Week marking the 36th anniversary of the fall of the Berlin Wall.
The gathering has brought together 180 participants from 60 countries including opposition figures, lawmakers, and rights activists from Iran, Russia, Venezuela, and China.
The event aims to coordinate global strategies to defend democracy and counter the spread of autocracy.
Practicing democracy in exile
Alinejad said the three founders of the World Liberty Congress had decided not to stand in this year’s internal elections to demonstrate democratic accountability.
“Mr. Leopoldo López, Garry Kasparov and I oppose Khamenei, Maduro and Putin, and to prove we are not like the dictators, we told the Berlin parliament that in the World Liberty Congress elections we will step aside so others can present themselves as the congress’s president, vice president and secretary this year.”
“This is an exercise to show democratic countries that we can hold elections and free ourselves from dictators,” added Alinejad.
The activist previously defined the World Liberty Congress as an alternative to the United Nations, which she said "has become a place to unite dictators."
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.
