Four Days of Water
The Gulf states make about two-fifths of the world’s desalinated water. In 2026 their plants were struck from the air, on both shores of the Gulf.
Some 56 plants account for more than nine tenths of the Gulf’s desalinated water.
Most of the coast receives under 100 millimetres of rain a year and has no permanent river. Its aquifers were charged during wetter periods, but are now being drawn down faster than they recharge. The remaining source is the sea, accessed through desalination.
Kuwait commissioned the first seawater plant in the early 1950s, and the rest of the coast followed. Desalination made it possible for cities of several million to stand where the water table could never have sustained them. The approach succeeded without qualification. But it also concentrated supply in a small number of sites on a single enclosed sea, replacing one form of scarcity with another.
For three of the six states, every seaborne input transits a single 34 km strait.
The major facilities are distributed along the Arab shore, concentrated between Kuwait Bay and the base of the Qatar peninsula. Bahrain, Kuwait and Qatar hold a single coastline each, entirely on this sea. Point at any marker to identify the site.
Nearly every input these plants consume arrives by sea: fuel, membranes, anti-scalants and the high-pressure pumps themselves. All of it transits the Strait of Hormuz, 34 km wide at its narrowest, which carries close to a fifth of world LNG trade in the opposite direction.
Three of the six retain an alternative. Fujairah lies beyond the strait on the Gulf of Oman, Saudi Arabia operates about a dozen plants on the Red Sea and conveys their output inland, and most Omani plants face the open sea. The six are routinely assessed as a single market. On this measure they are not comparable.
Water infrastructure reported damaged on both shores between March and July 2026. Only sites identified in the reporting carry a marker; where the affected plant was never named, the country carries a ring instead.
Plant positions are drawn from the MENA Water Review country map kit and are approximate. The 2026 markers record what each party reported; no strike on a water facility has been independently verified.
Oil, algae and malware reached the plants decades before a missile did.
Desalination plants have been hit both deliberately and accidentally. Iraqi forces destroyed most of Kuwait’s capacity by hand in 1991; an oil slick, an algal bloom and a piece of malware disabled other plants without being aimed at them. A facility that draws open seawater beside a power station is exposed along several axes at once.
What changed in 2026 was both the method and the range. Munitions directed at water infrastructure appear in the record from 2019. From 2026, they reach that infrastructure without an army having to arrive first.
- 1984–88
The Tanker War
Hundreds of ships are attacked in the closing years of the Iran–Iraq war, and the United States reflags Kuwaiti tankers to give them naval escort. The plants’ fuel and supplies share those lanes.
- 1991
The plants are destroyed on the ground
During the occupation Iraqi forces purposely destroy most of Kuwait’s desalination capacity. On withdrawing they set more than six hundred wells alight and release millions of barrels into the Gulf. Booms go up across the Saudi intakes and some plants shut down anyway.
- 2008–09
The red tide
An algal bloom closes plants in Oman and the UAE for up to two months. At Fujairah 1 the reverse-osmosis plant is down for more than a week.
- 2012
Shamoon
Malware wipes about 30,000 Saudi Aramco computers in a single day. US intelligence sources attribute it to Iran.
- 2019
Abqaiq
Missiles and drones briefly cut 5.7 million barrels a day, over half of Saudi production.
- 2019–22
Missiles toward the water
A Houthi rocket explodes near the Al-Shuqaiq plant on the Red Sea without damaging it; a desalination facility there is targeted again in 2022.
- 2020
The chlorine hack
A cyberattack widely attributed to Iran targets Israel’s water systems. Officials say chemicals could have been mixed in the wrong proportions.
- 2025
Twelve days in June
War reaches the Gulf: GPS jamming spreads, Iran’s parliament votes on closing Hormuz, and missiles are fired at Al Udeid. No plant is reported hit.
- 2026
The plants are hit
From 28 February water infrastructure enters the conflict on both shores: five Kuwaiti strikes, of which one plant is named, a Bahraini plant that is not, and three Iranian sites.
In 2026 both shores lost plants. Only one lost water.
On 2 March, a fragment of an intercepted drone ignited a fire at Doha West in Kuwait; the ministry reported minor material damage. Iran stated that a US strike had left the plant on Qeshm Island inoperable, interrupting supply to 30 villages. Bahrain stated that an Iranian drone had damaged one of its plants but that supply was maintained.
The heaviest damage came later. Kuwait was struck on 30 March, when a worker was killed; it was struck again on 3 April and twice within two days in July. The ministry then called for rationing. That same weekend, Iranian officials stated that a US strike had destroyed the pumping station at Bonji, near Jask. The strike cut off 20 villages and some 10,000 people during a heatwave.
People cut off from drinking water, where a figure was published
Both are in Iran, and both are the only incidents with a published population. Iran also reported 30 villages cut off at Qeshm without giving a number of people. Kuwait and Bahrain reported damage to plants without interruption to supply.
Every strike here is contested. Kuwait and Bahrain attribute theirs to Iran; Iran denies them and attributes the Kuwaiti strikes to Israel. Iran attributes its losses to the United States, which has not confirmed a strike on any water facility. None has been independently verified. Reports that the Fujairah plant was damaged were refuted by its operator.
About three-quarters of these plants generate electricity as well.
The older plants burn gas and use the resulting waste heat to boil seawater. This is an efficient arrangement, but it also means that water production stops when power generation stops. Newer plants force seawater through membranes at high pressure. They consume less energy, but depend on grid continuity. A damaged high-pressure pump takes weeks to replace rather than hours.
In both configurations, the dependency is the same. Water output is tied to the same fuel, the same grid and the same shipping lanes as the energy sector, all through the same strait. Here, a power failure is therefore a water failure to a degree it is not elsewhere.
A city that loses its plants retains only what it has stored.
A city on a river that loses its treatment works still has the river; its immediate problem is to repair the works. A city that depends on desalination has no equivalent source. If it loses its plants, it has only the water already in its reservoirs. Planning on this coast therefore starts with a single interval: the time between a halt in production and the failure of supply.
That interval governs everything that follows. It determines how long a repair may take, how far water can be moved by road, and whether rationing is a precaution or the final measure.
Kahramaa’s own count put the reserve behind Doha’s taps at 1.3 days: a city of well over a million people stood some thirty hours from the exhaustion of supply had production stopped.
About four days, as reported, with no natural aquifer in reserve. Bahrain operates 103 plants producing some 0.83 million cubic metres a day, all on the same coast.
Liwa holds its reserve in the aquifer rather than in open storage, where summer temperatures would return much of it to the atmosphere. Up to 90 days for one million people.
The interior minister put the strategic reserve at about four months in March 2026. From 1.3 days to roughly 120 in sixteen years is the clearest available measure of how seriously the exposure is now taken.
Figures as reported by utilities and governments. They rest on different assumptions about normal demand and emergency rationing and are not directly comparable.
The sea that supplies the Gulf supplies Iran as well.
Article 54 of the first Additional Protocol to the Geneva Conventions prohibits attacks on objects indispensable to the survival of the civilian population and explicitly names drinking-water installations. The record from 2026 shows how little that constraint held.
More than 90 per cent of Iran’s desalination capacity is sited in its southern provinces, on the same body of water, which takes about two years to flush through Hormuz. An oil slick or contamination at an intake would reach both coasts. This shared exposure most plausibly explains why the plants remained outside the war of June 2025. It did not keep them outside the next one.
Every state on the coast has spent a decade acquiring time. Qatar built surface storage, Abu Dhabi banked water in an aquifer, Kuwait has six underground reservoirs in planning, and Saudi Arabia retains its Red Sea capacity. The electricity grids were interconnected in 2009. A shared water grid remained only a feasibility study in mid-2026. The result is national resilience without regional redundancy, leaving the smallest systems the most exposed.
Both shores depend on the same sea
Share of the world’s desalinated water made by the six Gulf states, against the share of Iran’s own desalination capacity sited in its southern provinces. Different measures, one body of water.
