Data center cooling puts Gulf AI plans in front of a unpriced water constraint

Expansion plans for AI infrastructure in the Gulf states were built on calculations measured in gigawatts, accelerator allocations and sovereign investment volumes, but the most pressing challenge that has recently emerged is a unpriced water constraint, according to a policy paper documented by the Middle East Council for International Affairs researchers Abdel Fattah Hamid Ali and Mohamed Abu Hawash, alongside reports published by The National. The data show that the regional system has long treated water merely as an operating-expense line item, whereas in reality the Gulf water issue is an industrial capital project directly linked to generation and desalination capacities.

Estimates indicate that water demand for the AI sector in the United Arab Emirates alone could reach roughly 61 billion litres per year by 2030, a volume that servers do not consume chemically but that evaporates through cooling towers and chilled-water systems to maintain safe temperatures. With an expected compound annual growth of 29 percent in data-center power demand in Saudi Arabia, water consumption rises in parallel with computing density, with a conventional centre using about 300,000 gallons per day, while large facilities consume several million gallons daily in a coastal environment where summer temperatures climb to 40 C and humidity hampers evaporative-cooling efficiency.

The summer peak in data-center operation coincides with the narrowest network-link margins at dual electricity-and-desalination production plants.These requirements arise in a region that holds only about 2 percent of the world’s renewable freshwater resources, while 83 percent of its land faces acute water stress according to the Global Resources Institute. The region has invested $53.4 billion in desalination projects between 2006 and 2024, representing 47.5 percent of total global capital spending on desalination, with forecasts of an additional $26 billion in spending by 2028, making a continuous, round-the-clock water load an additional pressure on existing infrastructure.

Although engineering solutions tested and released by regional firms such as Khazna in Abu Dhabi and DataVolt and Al-Fanar in Saudi Arabia, using direct-liquid cooling for chips and immersion cooling, which can cut cooling-water use by up to 90 percent while also reducing electricity consumption, regulatory frameworks still lack unified mandatory standards for combined water-and-energy efficiency, or requirements to use non-potable water and expand treated-waste-water networks.

Water availability shifts from a mere service detail to a key variable governing site-selection decisions and the speed of licensing.This equation gives an advantage to coastal projects or facilities that rely on closed-loop liquid cooling compared with inland sites that compete with agriculture and municipal consumption, prompting sovereign infrastructure programmes to embed water management as a core design criterion to accelerate linking computing capacity to the grid and to export environmental standards for hot regions worldwide.
