Resilience by Design: Next Generation Water Security in the Gulf

By Alexei Levene, Co-founder and Chief Commercial Officer, Desolenator

If the UAE's desalination plants stopped tomorrow, the country's stored water would last two to three days. Under emergency rationing, it might stretch to somewhere between 16 and 45. .

Desalination meets half of the UAE's water demand, and just four plants provide around 60% of that capacity. In its way, that concentration is a mark of success: the Gulf has built some of the most efficient water systems on earth by concentrating production in a few very large coastal plants. But a system designed for efficiency is not the same as one designed to survive a shock..

For decades, we have treated water as a cheap commodity, produced in bulk on the coast and piped inland. That assumption no longer holds. The slow burn of climate change is now joined by the more immediate risks of conflict, supply-chain shocks and grid failures. Water has stopped being a routine utility and become a question of national resilience..

Everything runs on water

When water fails, the damage does not stay in the water sector. A data center that loses its cooling water has to slow its servers. A greenhouse without irrigation loses a season’s crops. An industrial park without process water simply stops. Food security, digital sovereignty and industrial output all depend on a handful of seawater intakes.

None of this is an argument against the big plants. They should remain the backbone of national supply, and the UAE continues to invest in them: more than $10 billion of desalination projects have entered the pipeline since 2023. But a backbone is only one layer, and concentration carries its own risks. An oil spill or an algal bloom near an intake can take capacity offline within hours. The membranes, chemicals and spare parts that arrive by sea are a strategic dependency. Resilience cannot be bolted onto a system that has only one line of defense.

The missing middle

What the Gulf needs is a water system with three layers. At the base are the national plants, each producing 100,000 cubic meters a day or more. At the top are emergency measures, such as mobile desalination units that can be rushed to wherever supply has failed. The layer missing today is the one in between: smaller plants of 1,000 to 10,000 cubic meters a day, built beside the facilities that can least afford to go dry.

This middle layer should rest on five pillars of water resilience. It should be:

Complementary. It backs up the national plants rather than competing with them, protecting the industries and communities that can least afford an outage.

Diversified. It draws on several water sources and technologies, so no single failure takes everything down.

Flexible. It is modular, so capacity can be added as demand grows.

Sovereign. It is built and serviced through local supply chains, not parts shipped from abroad.

Innovative. It uses newer technology to turn waste, such as excess heat, into water.

The data center is the clearest case. Its servers throw off huge amounts of low-grade heat, often removed by cooling towers that themselves consume water. That heat could instead drive thermal desalination on site, evaporating seawater and condensing it as fresh water for the facility and potentially its neighbors. Worldwide, more than 3,000 terawatt-hours of heat go to waste every year. In the Gulf, much of it is produced right next to the assets that need water.

This already works in the field. With DEWA, Dubai's water and power utility, at Jebel Ali, and with the agri-food company Silal in Al Ain, my company Desolenator has produced drinking and irrigation water from highly saline Gulf seawater and brackish desert groundwater. Distillation does not depend on imported membranes or chemicals, and it can run off the grid on solar power and stored heat. Where waste heat is available, it can also lower the cost of water.

Built at home

Where water is made is only half the question. The other half is whether a country can build and repair its plants when shipping lanes close. A decentralized network that relies on imported parts and foreign service crews has simply moved its weak point somewhere else.

A resilient supply chain requires local manufacturing, developed in stages: assembly first, then component production, eventually reaching more than 80% local content.

Domestic scale can take a third off the cost of every cubic meter, and the skilled jobs and intellectual property stay in the country.

Policymakers could start with three steps. Commission anchor projects in the sectors where losing water costs most. Expect new data centers and industrial zones to use their waste heat to make water. And classify distributed water plants as critical national infrastructure.

Made in Abu Dhabi, shared with the world

The Gulf has a habit of turning hard limits into leadership. When the UN Water Conference comes to the UAE in December, the region will have a rare chance to define what a resilient water supply looks like, and then to export the model. From North Africa to South Asia, countries short of water need systems that are proven, affordable and under their own control.

The Gulf has already shown it can build one of the most efficient water systems in the world. Its next achievement should be a system that keeps running when something goes wrong.
