Artificial intelligence needs vast computing power, and that power now depends on water. In the Middle East and North Africa (MENA), one of the world’s driest regions, this creates a serious new pressure on already scarce resources.

Why AI Data Centers Need Water

AI data centers generate intense heat as servers train and run large models. Operators often rely on water-based cooling, either through evaporative systems that directly consume freshwater or through chillers and towers that use large volumes indirectly. Water is also embedded in the electricity that powers these facilities, because many power plants themselves need water for cooling.

Recent research shows how quickly this adds up. Training a single large model can consume millions of liters of water when you include both onsite cooling and the power supply. One study estimates that answering 20 to 50 AI queries can use the equivalent of a 500‑milliliter bottle of water, when you count the full water footprint of the data center and grid.

A Thirsty Technology In The World’s Driest Region

MENA holds about 6.3% of the world’s population but only around 1.4% of its renewable freshwater, making it the most water‑stressed region on Earth. Of the 17 most water‑stressed countries globally, 11 are in MENA, and some forecasts warn that almost the entire population could face acute scarcity by 2050 if trends continue.

At the same time, Gulf states and other regional economies are racing to become AI and cloud hubs. New data centers are rising in Saudi Arabia, the United Arab Emirates, Qatar and beyond, often in areas where rainfall is minimal and summer temperatures soar above 40 degrees Celsius. Analysts expect regional data center water use to grow rapidly this decade as AI clusters demand denser, more water‑intensive cooling.

Desalination, Energy And The Water–Energy Nexus

Because natural freshwater is so limited, many MENA countries depend heavily on desalination. In Kuwait, about 90% of drinking water comes from desalinated sources; in Oman it is around 86%, in Saudi Arabia nearly 70%, and in the UAE more than 40% of municipal supply. The region already accounts for roughly 42% of global operational desalination capacity, with thousands of plants producing tens of millions of cubic meters per day.

Desalination is lifeline and burden at once. It is energy‑intensive and can harm marine ecosystems through brine discharges, so each extra unit of water for cooling AI infrastructure can also mean more emissions and coastal impacts if powered by fossil fuels. Experts argue that integrating solar and wind power into desalination and water treatment is essential to keep this nexus from becoming a vicious circle.

Emerging Solutions For Water‑Smart AI

There are promising technical responses. In the MENA, some large data centers now use closed‑loop systems and onsite treatment that recycle up to 96% of process water. Mega‑campuses in Saudi Arabia and the Gulf are pairing photovoltaic‑powered desalination with advanced cooling designs, using underground thermal storage and waste‑heat recovery to cut both water use and energy demand.​

Globally, major cloud providers are also rethinking their strategies. Microsoft’s own projections showed that its annual water use for data centers could more than triple by 2030, before it revised designs and targets to curb the increase. Independent reviews still find sharp year‑on‑year rises in water consumption for Microsoft and Google, underlining how fast AI is outpacing earlier efficiency gains.

Policy And Transparency Gaps

Despite the scale of the challenge, water data for AI facilities in MENA remains patchy. Many companies do not disclose their withdrawals or consumption, because regulation has not yet caught up with the speed of investment. This lack of transparency makes it hard for communities and policymakers to judge trade‑offs between digital growth and local water security.

Some governments and regional bodies are starting to respond. New water‑energy strategies, desalination partnerships and water security task forces in the Gulf link future infrastructure to renewable energy, wastewater reuse and stricter efficiency standards. To keep AI compatible with a liveable future in MENA, these efforts need to go further—making water‑smart cooling, regenerative desalination and full public reporting standard features of every new data center, not optional extras.
