The plants become targets: Gulf water in the 2026 war

Between 44 and 60 per cent of the world’s desalination capacity sits in the six Gulf Cooperation Council states, depending on whose count is used.⁶⁷ More than 90 per cent of the Gulf’s desalinated supply comes from 56 plants. Qatar takes 99 per cent of its drinking water from the sea, Bahrain and Kuwait over 90, Saudi Arabia about 70.⁵

That concentration had been attacked before. Iraqi forces destroyed most of Kuwait’s desalination capacity in the 1990 to 1991 Gulf War,⁷ and Saudi Arabia’s Shuqaiq plant later weathered Houthi attacks.⁵ Even so, the plants were widely treated as off-limits, on the argument that everyone on every shore drinks the same sea.

The reading did not survive 2026. A wider war opened on 28 February, and on 7 March a desalination plant on Iran’s Qeshm Island was struck, cutting supply to about 30 villages. It was still out of service a month later. The United States and Israel both denied carrying out the attack.¹

A day later an Iranian drone damaged a plant in Bahrain, which Iran’s foreign minister called retaliation for a US attack.² Kuwait’s stations were hit repeatedly. A service building at a power and water station was hit on 30 March, killing an Indian worker.³ A power and desalination plant was hit on 3 April, and two more were damaged in overnight attacks two days later.⁸⁹ A strike in July caused what the government called widespread damage.⁴ Iran said power and desalination units serving the Assaluyeh petrochemical complex were hit too.¹

Supply held. Bahrain’s Electricity and Water Authority confirmed that water and electricity services to residents were not affected. That is the clearest operational fact in the record.² Three people were hurt by missile fragments in Muharraq.¹⁰

The record on one plant is contested rather than settled. In a report of 9 March, Sembcorp said its Fujairah plant had not been damaged, suggesting that damage in the industrial or port zone had been mistaken for damage to the plant.¹² Ten days later CSIS still listed Fujairah F1 and Doha West as having taken damage from missiles or falling debris.¹¹ A strike on Dubai’s Jebel Ali port landed close to a complex holding 43 desalination units, not on it.¹²

The system held because the damage was partial and repairable, and because these are large fleets with redundancy. By late April no significant disruption to water supply had been reported.¹ Nothing in the public record establishes what would have happened to a state holding four days of water, had a strike been more accurate.

Six months on, no Gulf government or utility has announced a funded storage programme or hardening measure in response. GCC leaders did list water interconnection and strategic reserves among joint priorities at a meeting on 28 April.¹³ Qatar’s mega-reservoirs were inaugurated in December 2018 and Abu Dhabi’s Liwa reserve was completed that January, so both predate the war by more than seven years.¹⁴¹⁵ Either the spending is not happening or it is not being announced, and the public record does not say which.

The buffer itself is barely published. Compiled wartime estimates put Bahrain near four days, Saudi Arabia five to six, and Kuwait ten to fifteen. The United Arab Emirates is reported to hold two at normal consumption, rising to 16 under emergency rationing and 45 under severe. Qatar was reported to claim four months.¹ The estimates disagree because almost nobody publishes the number. For a region whose exposure is now demonstrated, that is itself a finding.

The law did not deter anyone. Article 54 of Additional Protocol I to the Geneva Conventions prohibits attacking objects indispensable to civilian survival, and names drinking water installations explicitly.¹⁶ The director of the United Nations University’s water institute said any attack on energy or water facilities would be a war crime.¹⁷ The strikes continued for four more months.⁴

Shared exposure is not a deterrent. It was the load-bearing assumption of Gulf water security, and 2026 disproved it. What kept the taps running was redundancy and inaccuracy, not restraint.

The historian Michael Christopher Low put the escalation plainly. The only rungs above this on the ladder were desalination plants and nuclear facilities, and both have now been targeted.⁵ Carnegie called the shift qualitative and proposed treating water infrastructure as a shared red line, with hydrological security handled as strategic security.¹⁸ The Arab Center in Washington urged that attacking water infrastructure be made a red line outright.¹

For a utility the consequences are unglamorous, and mostly not about walls. Storage duration decides how much damage matters, and it is the variable least published and least funded. Distributed capacity is worth more than a single larger plant. Chemicals and membranes arrive by sea, through a strait that Iran closed and later mined.¹⁹ Chemical supply chains were reported holding a few weeks of inventory, with six to nine months expected before meaningful supply returns.²⁰ No desalination-specific shortage has been documented, which is the difference between an exposure and a failure. It is not a difference to rely on twice.
