Humans cannot drink saline water, but, saline water
can be made into freshwater
, for which there are many uses. The process is called “desalination”, and it is being used more and more around the world to provide people with needed freshwater.

boiling the water and collecting the vapor (thermal)
or by pushing it through special filters (membrane).

How can we purify sea water so it is safe to drink?
Reverse osmosis and
distillation
are the most common ways to desalinate water. Reverse osmosis water treatment pushes water through small filters leaving salt behind. Distillation on a large scale involves boiling water and collecting water vapor during the process.
Which country uses sea water for drinking?

Saudi Arabia
— Desalinated seawater is the lifeblood of Saudi Arabia, nowhere more so than at King Abdullah University of Science and Technology, an international research center that rose from the dry, empty desert a decade ago.
Is water desalination expensive?
Seawater desalination is
one of the most expensive sources of fresh water
. The total costs of desalination, including the costs of planning, permitting, and concentrate management, are high, both in absolute terms and in comparison with the costs of other alternatives.
How does Saudi Arabia get water?
