Groundwater depletion could take up to 70,000 years to recover as Tehran nears total water shutdown
As Iran’s water crisis reaches a critical tipping point, leading environmental experts are issuing dire warnings about the country’s future. Mohammad Darvish, a environmentalist and university professor, has stated that it could take between 65,000 to 70,000 years to restore Iran’s depleted groundwater reserves—if restoration is even possible.
At the same time, the British magazine The Week has warned that Tehran—home to over 10 million people—may be only weeks away from “Day Zero,” the moment when taps run dry across vast parts of the city.
Iran’s Groundwater: A Lost Resource?
In a report published on August 2 by Etemad newspaper titled “We Must Wait 70,000 Years for Groundwater to Return,” Darvish explained the catastrophic scale of groundwater depletion in Iran. He stated that Iranians have extracted approximately 150 billion cubic meters more water than has naturally replenished the aquifers over the last three decades. As a result, large swaths of the country are now experiencing land subsidence—a dangerous downward shift in the earth’s surface.
“Land subsidence has already affected at least 57,000 square kilometers, sinking at an average rate of one centimeter per year,” Darvish noted. He warned that the country is in the final stage of desertification, where even if all water extraction were to stop immediately, the aquifers would remain unrecoverable for tens of thousands of years.
In response to the question of whether the nation should give up hope of restoring its groundwater, Darvish replied with a chilling remark:
“You can wait—just 65,000 to 70,000 years. If you’re that patient, then you can hope the groundwater might return to ideal conditions.”
A Landscape Beyond Repair
Darvish painted a bleak picture of Iran’s landscape. He explained that many regions are now so geologically compromised that they can no longer support construction, transportation infrastructure, or even basic utility installations. These lands have been effectively rendered unusable due to severe environmental degradation.
Citing recent findings by the Iranian Geological Organization, Darvish noted that land subsidence is spreading rapidly. In 2016, approximately 11,000 square kilometers were affected. That figure has since ballooned to 100,000 square kilometers, with an average annual subsidence of two centimeters—a dramatic and alarming escalation.
Tehran Nears “Day Zero”
The Week has sounded the alarm on what may be the most immediate threat: Tehran’s imminent water shutdown. The magazine warned that the capital is “just weeks away” from Day Zero—the day when water will no longer flow from household taps in large parts of the city.
Describing the situation as “water bankruptcy,” the report blamed a combination of prolonged drought, climate change, and chronic mismanagement of water resources. Analysts cited in the report warned that this looming crisis is not just a humanitarian disaster—it could also threaten the regime’s political stability.
The crisis has already begun affecting daily life. The Tehran Water Department recently shut down public restrooms due to water shortages, a move that has created serious hardships for workers, children, patients, and commuters across the city.
Regime Acknowledges Crisis—Too Late?
On July 31, Iranian regime president Masoud Pezeshkian acknowledged the severity of the crisis, warning that Iran is “on the verge of a serious water catastrophe.” Despite this admission, environmental experts say such warnings are too little, too late—especially after decades of reckless water policies and lack of investment in sustainable infrastructure.
The Week emphasized that while droughts have intensified the crisis, the root causes lie in unsustainable practices: excessive groundwater extraction, inefficient agricultural systems, and unchecked urban water consumption.
Darvish had earlier warned:
“If urgent decisions are not made, we will face a future that cannot be resolved.”
A Threat to Iran’s Biological and Political Survival
Environmental specialists now warn that Iran’s water crisis is no longer just an ecological issue—it poses a direct threat to the country’s biological survival and political continuity. Without immediate and comprehensive reforms—including long-term strategic planning, public education, and significant changes to consumption habits—Iran may face not just mass thirst, but social unrest and systemic collapse.
In the face of such unprecedented danger, time is running out. The taps are still flowing—for now—but unless decisive action is taken, Iran’s “Day Zero” may soon become a grim reality.
