The city relies on desalination to provide clean drinking water.
As the population grows and the reservoirs shrink, the government is investing heavily in desalination plants along the coast.
While desalination provides a reliable source of potable water, the high energy consumption and environmental impact of the process remain significant challenges for sustainable urban planning in coastal deserts.
From de- + salination.
