Gulf Desalination Plants Under Fire as Water Infrastructure Becomes War Target
The escalating violence in the Gulf region has taken a dangerous new turn, with civilian infrastructure increasingly becoming a primary target for warring military powers. Among the most critical assets now in the crosshairs are desalination plants, which have become essential to human survival in this arid part of the world. Experts are issuing stark warnings that if these facilities continue to be attacked, entire cities may face forced evacuation within days.
Exchange of Accusations Over Plant Attacks
On Sunday, Bahrain officially accused Iran of launching a drone strike that caused material damage to one of its desalination plants on the island nation. Bahraini authorities condemned what they described as indiscriminate attacks on civilian targets. This accusation came just one day after Iran made similar claims against the United States, alleging that American forces had attacked a desalination facility on Qeshm Island, disrupting water supplies to approximately thirty villages.
Iran's foreign minister, Abbas Araghchi, characterized Saturday's alleged attack as a dangerous move with grave consequences, accusing the United States of setting a dangerous precedent. American officials have firmly denied any involvement in targeting water infrastructure. The conflict, which began on February 28th with coordinated US and Israeli strikes against Iranian targets, has already brought hostilities dangerously close to vital desalination facilities across the region.
Expert Warnings of Catastrophic Consequences
Dr. Marc Owen Jones, a professor at Northwestern University in Qatar, provided a chilling assessment during an interview with Radio 4's Today programme. They're crucial. The absence of these plants would be huge, he stated. In Riyadh, if certain desalination plants were attacked, the city would have to evacuate after about a week. He emphasized that the vulnerability extends beyond direct attacks on the plants themselves, noting that these are energy intensive, so if you attack the energy infrastructure, you can't power them and they will go offline.
Dr. Jones suggested that Iran may be deliberately targeting civilian infrastructure as a strategic pressure tactic against its Gulf neighbors. These attacks are meant to create a level of panic, he explained. If Gulf governments believe that water infrastructure is under attack, they would be more likely to put pressure on the US to try and end the war. This perspective frames the targeting of water facilities as part of a broader information war aimed at forcing diplomatic intervention.
Widespread Regional Vulnerability
The entire Gulf region depends overwhelmingly on desalination technology for freshwater. Hundreds of plants line the Persian Gulf coast, placing systems that supply millions of people within easy range of missile and drone attacks. The statistics reveal the scale of this dependency:
- Kuwait sources approximately 90% of its drinking water from desalination
- Oman relies on desalination for about 86% of its freshwater needs
- Saudi Arabia obtains roughly 70% of its drinking water through desalination
These facilities use reverse osmosis technology to remove salt from seawater, producing the freshwater that sustains cities, industries, and limited agriculture across one of the world's driest regions. Without them, major urban centers could not support their current populations.
Historical Precedents and Growing Concerns
The vulnerability of Gulf water infrastructure is not a new concern. A 2010 CIA analysis warned that attacks on desalination facilities could trigger national crises in several Gulf states, with prolonged outages potentially lasting months if critical equipment were destroyed. The report noted that more than 90% of the region's desalinated water comes from just fifty-six plants, each extremely vulnerable to sabotage or military action.
David Michel, senior fellow for water security at the Centre for Strategic and International Studies, described the targeting of water infrastructure as an asymmetrical tactic. Iran doesn't have the same capacity to strike back at the United States and Israel, he observed. But it does have this possibility to impose costs on the Gulf countries to push them to intervene or call for a cessation of hostilities.
Multiple Points of Vulnerability
Ed Cullinane, Middle East editor at Global Water Intelligence, explained that desalination plants have multiple vulnerable components. None of these assets are any more protected than any of the municipal areas that are currently being hit by ballistic missiles or drones, he stated. The plants typically consist of intake systems, treatment facilities, and energy supplies, with damage to any part of this chain capable of interrupting production entirely.
Many Gulf desalination plants are physically integrated with power stations as co-generation facilities, meaning attacks on electrical infrastructure could simultaneously cripple water production. Even where plants are connected to national grids with backup supply routes, disruptions can cascade across interconnected systems with devastating consequences.
Broader Implications for International Norms
Dr. Noha Aboueldahab, a professor at Georgetown University in Qatar, emphasized the legal dimensions of these attacks during her Today programme interview. Iran has said it is within its right to exercise its self-defence, she noted. There are limits to how it exercises this self-defence. Attacks on desalination plants, whether in Bahrain or elsewhere, are unlawful. International humanitarian law, including provisions of the Geneva Conventions, explicitly prohibits targeting civilian infrastructure indispensable to population survival, including drinking water facilities.
These incidents reflect a broader erosion of long-standing norms against attacking civilian infrastructure, with parallels visible in conflicts in Ukraine, Gaza, and Iraq. The potential for harmful cyberattacks on water infrastructure represents an additional growing concern, with US officials blaming Iran-aligned groups for hacking into several American water utilities in 2023 and 2024.
Iran's Own Water Challenges
Ironically, Iran faces significant water challenges of its own. Unlike many Gulf states that rely heavily on desalination, Iran still obtains most of its water from rivers, reservoirs, and depleted underground aquifers. The country operates a relatively small number of desalination plants, supplying only a fraction of national demand. After five years of extreme drought, water levels in Tehran's five reservoirs have plunged to approximately 10% of their capacity, prompting President Masoud Pezeshkian to warn that the capital may need to be evacuated.
They were already thinking of evacuating the capital last summer, noted Cullinane. I don't dare to wonder what it's going to be like this summer under sustained fire, with an ongoing economic catastrophe and a serious water crisis. Iran is attempting to expand desalination along its southern coast and pump water inland, but infrastructure constraints, energy costs, and international sanctions have sharply limited scalability.
Historical Parallels and Future Risks
The current situation evokes historical precedents with disturbing parallels. During Iraq's 1990-1991 invasion of Kuwait and the subsequent Gulf War, retreating Iraqi forces deliberately sabotaged power stations and desalination facilities. Simultaneously, millions of barrels of crude oil were intentionally released into the Persian Gulf, creating one of history's largest oil spills. The massive slick threatened to contaminate seawater intake pipes used by desalination plants across the region, forcing workers to deploy protective booms around intake valves. The destruction left Kuwait largely without fresh water and dependent on emergency imports, with full recovery taking years.
More recently, Yemen's Houthi rebels have targeted Saudi desalination facilities amid regional tensions. These incidents underscore how water infrastructure has become a strategic target in modern conflicts, with potentially catastrophic humanitarian consequences for civilian populations caught in the crossfire of geopolitical struggles.
