Desalination Plants Under Fire in the Gulf Conflict: Legal and Humanitarian Implications

In early March 2026, reported strikes damaged desalination facilities in both Iran and Bahrain, disrupting water supply to civilian populations and raising alarm across the region. These incidents highlight a growing and dangerous trend, the increasing entanglement of essential water systems in contemporary warfare.

Water Infrastructure at the Heart of Civilian Survival

In the Gulf region, desalination is not a supplementary resource, it is the backbone of water security. Approximately 100 million people rely on desalinated water, with some countries sourcing nearly all their drinking water from these systems.

The disruption of a single desalination plant can therefore have cascading effects: hospitals face shortages, food systems are strained, and entire urban populations are placed at risk. These reverberating impacts extend far beyond immediate physical damage, amplifying humanitarian crises in already fragile contexts.

What Does International Law Say?

Under international humanitarian law (IHL), desalination plants are considered civilian objects and, more specifically, objects indispensable to the survival of the civilian population. As such, they benefit from heightened protection.

This means:

• They must not be directly targeted
• Attacks causing excessive civilian harm relative to military advantage are prohibited
• All feasible precautions must be taken to avoid damage

Even in cases where military objectives are present, the principles of distinction, proportionality, and precautionremain binding.

Importantly, violations by one party do not justify reciprocal attacks. The legal framework is designed precisely to prevent escalation and the normalization of targeting essential civilian infrastructure.

A Strategic and Humanitarian Imperative

Beyond legal obligations, the targeting, or incidental damage, of water infrastructure carries significant strategic risks. Once normalized, such practices expose all parties to similar vulnerabilities, creating a cycle of retaliation that disproportionately affects civilian populations.

The events observed in March 2026 underscore a broader reality:
water systems are increasingly weaponized in modern conflicts, with severe humanitarian and environmental consequences.

The Need for Restraint and Protection

Protecting water infrastructure is not only a matter of legal compliance, it is central to preserving human dignity, preventing further instability, and maintaining pathways to peace.

As a Centre of Competence on Water for Peace, the Geneva Water Hub reiterates the importance of:

• Upholding international humanitarian law
• Recognizing water infrastructure as critical civilian systems
• Preventing the normalization of attacks on water

Safeguarding water means safeguarding life.
