(Al Jazeera Media Network) Bahrain has said an Iranian drone attack caused material damage to a water desalination plant in the country, marking the first time a Gulf nation has reported targeting any such facility during the eight days of the war between Iran and the US and Israel.
The attack on Sunday comes a day after Iranian Foreign Minister Abbas Araghchi said a freshwater desalination plant on Qeshm Island in southern Iran was attacked by the United States.
“Water supply in 30 villages has been impacted. Attacking Iran’s infrastructure is a dangerous move with grave consequences. The US set this precedent, not Iran,” he said on X on Saturday.
While Tehran has not yet commented on the Bahrain attack, it has raised questions about the vulnerability of the Gulf countries, which depend on desalination plants for the majority of their water supply.
How important are water desalination plants to the Gulf region? Can water security in the Gulf be guaranteed amid a widening of military targets to include energy and other civilian sites?
A desalination plant primarily converts seawater into water suitable for drinking purposes as well as for irrigation and industrial use.
The process of desalination involves removing salt, algae and other pollutants from seawater using a thermal process or membrane-based technologies.
According to the US Department of Energy, desalination systems “heat water so that it evaporates into steam, leaving behind impurities, and then condenses back into a liquid for human use.”
Meanwhile, membrane-based desalination involves “a class of technologies in which saline water passes through a semipermeable material that allows water through but holds back dissolved solids like salts.”
Reverse osmosis is the most popular membrane technology. Most countries in the Gulf Cooperation Council (GCC) use reverse osmosis since it is an energy-efficient technique.
Water is scarce in the Gulf region due to the arid climate and irregular rainfall. Countries in the Gulf also have very limited natural freshwater resources. Groundwater, together with desalinated water, accounts for about 90 percent of the region’s main water resources, according to a 2020 report by the Gulf Research Center.
