Between March and August 2026, desalination plants in Kuwait and Bahrain were damaged in attacks. Not once, and not in one place. That changes what a desalination plant is: it is no longer only an industrial asset, it is part of a country's civil defence.
This page brings together what DME has published on the question.
What happened
An Iranian strike damaged a Kuwaiti power and desalination plant, and further attacks hit facilities in Bahrain. Kuwait draws the overwhelming share of its drinking water from desalination. A different threat, the same lesson: after the vessel Caroline Bezengi ran aground off the Al Hallaniyat Islands, an oil slick spread across some 390 km² of Omani coastal water. Oman's Environment Authority confirmed that the desalination plants and the coastal zone were not affected.
Where the weak point is
The plant itself is rarely the weak point, the power feed and the intake are. In Oman, too, the plant was never the risk, the intake was. That an authority could check and confirm quickly is not luck, it is monitoring built in advance. Whether the Gulf's water could really be cut off depends on which plants, which capacities and which reserves, and on where the assumption of a quick collapse does not hold.
Reliability is not resilience
Most plants in the Gulf were designed for reliability, not for hostility. Reliability asks what fails on its own; resilience asks what happens when something is made to fail, and how fast the rest carries on. Three questions separate the two:
- How long does the country hold without you? Storage in days, not in cubic metres.
- What is the one thing that stops everything? Usually the power feed, the intake, or a single high-voltage building. Redundancy that shares a room is not redundancy.
- How fast can you run at part load? Forty per cent output tomorrow beats one hundred per cent in three months.
Coupling with renewables, distributed capacity and part-load capability are questions that belong on the drawing board, not in the crisis meeting. It costs a fraction at the design stage of what it costs after an event.
