War reaches the Gulf’s water lifeline

A drone strike that damaged a desalination facility in Bahrain has drawn attention to an emerging dimension of the regional conflict: the vulnerability of water infrastructure. In a part of the world where desalination supplies drinking water to millions, even limited disruptions carry outsized consequences. The strike has renewed focus on systems that typically operate in the background of Gulf economies but now fall within the expanding reach of the war.

The backbone of Gulf water supply

Across the Arabian Peninsula, the arid landmass in southwest Asia that includes Saudi Arabia, Yemen, Oman, the United Arab Emirates, Qatar, Kuwait, and Bahrain, desalination plants form the backbone of national water systems. Research by the Arab Center Washington DC estimates that Gulf countries alone account for roughly 60 percent of global desalination capacity and produce about 40 percent of the world’s desalinated water, underscoring the region’s central role in the technology’s development.

The scale of reliance varies by country but remains striking across the Gulf. Kuwait obtains roughly 90 percent of its drinking water from desalination, while Oman derives around 86 percent and Saudi Arabia approximately 70 percent from the same process. Even in the United Arab Emirates, where groundwater and other sources supplement supply, desalinated seawater still accounts for about 42 percent of potable water.

Such dependence reflects the region’s geography. Much of the Arabian Peninsula lacks permanent freshwater rivers and receives limited rainfall, leaving governments with few natural water sources. Beginning in the mid-twentieth century, and expanding rapidly from the 1970s onward, Gulf states invested heavily in large-scale desalination plants.

Over time, these facilities evolved from experimental technology into foundational infrastructure. Today, hundreds of desalination plants operate across the Gulf, producing the water that sustains homes, industries, and rapidly growing urban populations.

Enabling urban growth in a water-scarce region

Large-scale desalination has played a central role in the Gulf's economic and demographic transformation. In a 2025 report, analysts at the Atlantic Council, a Washington-based think tank, noted that the technology effectively decoupled urban expansion from natural freshwater constraints, allowing cities to grow despite extreme water scarcity.

That shift fundamentally reshaped regional planning: coastal desalination plants were integrated with power generation facilities and distribution networks capable of transporting treated water long distances inland, helping sustain rapidly expanding populations and modern urban infrastructure in environments that historically supported far smaller communities.

The systems are also deeply embedded in regional energy networks, with many plants operating alongside power stations to enable large-scale production of both electricity and fresh water  supporting broader economic development across the region.

Infrastructure concentration and wartime vulnerability

Desalination systems often rely on a relatively small number of large coastal facilities. Studies of desalination development in the Middle East, including research by the French Institute of International Relations, note that plants are typically concentrated along coastlines to access seawater and integrate with energy infrastructure.

In peacetime, this geography allows desalination plants to operate efficiently alongside ports, industrial zones, and power generation facilities. In wartime, however, the same concentration can place water infrastructure within the broader landscape of strategic targets.

The strike reported in Bahrain illustrated this dynamic. Although the drone attack caused damage to the desalination facility, Bahraini authorities reported no major disruption to water supply. Even so, the incident underscored how infrastructure sustaining civilian life can sit within the same coastal corridors that host ports, energy terminals, and transportation hubs.

War and the future of water infrastructure

The Bahrain strike occurred within a broader conflict that has increasingly drawn infrastructure into its path. Airports, fuel depots, and industrial zones across the region have also been targeted.

Desalination plants occupy a distinctive position because they sit at the intersection of energy systems and civilian services. Producing fresh water from seawater requires large amounts of electricity, linking water supply to the same coastal corridors that host ports and power stations.

Damage at the Bahraini facility appears to have caused limited disruption to water supply. But the incident highlights how the geography of the war is intersecting with the infrastructure that sustains daily life across the region.
