Using Desalination Infrastructure as a Weapon of War
Summary
Since the outbreak of war with Iran on February 28, 2026, critical water desalination infrastructure across the Persian Gulf region has come under direct threat and attack. Confirmed incidents include a U.S. strike damaging an Iranian desalination plant on Qeshm Island, an Iranian drone strike hitting a desalination facility in Bahrain, and an attack on a power and desalination site in Kuwait on March 30. The stakes are extraordinarily high given that Gulf states depend on approximately 300 major desalination facilities to supply between 70 and 90 percent of their urban water needs, making these facilities existential infrastructure rather than simply strategic assets. Both sides have issued explicit threats, with Iran warning it could destroy Arab Gulf states' desalination plants and President Trump threatening to target Iranian desalination facilities if the Strait of Hormuz remains closed. Five experts were consulted to assess the broader vulnerabilities of desalination infrastructure globally and to recommend how nations should prepare to protect these critical water systems.
Key Takeaways
- 1. Desalination plants in the Persian Gulf are actively being targeted in the Iran conflict, marking a dangerous escalation involving civilian water infrastructure
- 2. Gulf states face an existential water security crisis, as desalination supplies up to 90% of urban water in the region
- 3. Both the U.S.-Israeli coalition and Iran have made explicit threats to destroy each other's desalination facilities as instruments of coercion
- 4. Desalination plants are equally as vulnerable to attack as oil refineries and LNG facilities, which have already been struck in the conflict
- 5. The conflict highlights that desalination infrastructure worldwide, not just in the Gulf, is dangerously exposed to military and terrorist threats
