Gulf Countries Face Water Security Risk as Over 60% Drinking Water Depends on Desalination Plants

Saudi Arabia, Qatar and Bahrain depend on desalination plants for over 60% of drinking water. Experts warn that any disruption could lead to severe water crisis and unrest.

Manama: Desert nations in the Gulf region are facing a silent but serious vulnerability — extreme dependence on desalination plants for their daily water needs. Countries such as Saudi Arabia, Qatar and Bahrain have almost no natural freshwater resources. With negligible rainfall, no major rivers, and limited groundwater reserves, these nations rely on converting seawater into drinking water to sustain their populations. According to experts, more than 60 percent of drinking water in these countries comes from desalination plants. In some urban regions, the dependency level is even higher, making desalination the backbone of national water supply systems. Why the Risk Is Serious Water analysts warn that if desalination plants stop functioning due to power failure, technical faults,

 cyberattacks, or geopolitical tensions,

the impact could be immediate. Most Gulf cities maintain limited emergency water reserves, often sufficient only for a short period. With summer temperatures frequently crossing 45°C, daily water consumption remains extremely high. A sudden shutdown could lead to shortages within hours, sparking panic, supply disruptions, and potential public unrest. “Unlike river-based countries, these nations have no natural backup system. Desalination is their lifeline,” a senior water policy expert stated. Energy-Dependent Water System Desalination plants consume massive amounts of electricity, mostly generated from fossil fuels. This creates a direct link between energy security and water security. Any disruption in power supply can instantly affect water production. Recognizing this vulnerability, Gulf governments are investing in renewable-energy-powered desalination, expanding strategic water storage, and strengthening infrastructure protection. Environmental and Future Challenges Environmental experts also caution that desalination produces highly concentrated brine, which is discharged back into the sea, potentially impacting marine ecosystems in the Arabian Gulf. With climate change, population growth, and industrial expansion increasing demand, long-term sustainability of water supply remains a critical challenge. A Matter of National Security Water security is now treated as a strategic priority in the Gulf. Desalination plants are classified as critical infrastructure and are under heightened protection. While technology has enabled these desert economies to flourish, experts stress the need for diversified water sources and emergency preparedness plans to avoid
