Thanks for the clarification.
I was in Portsmouth one time when they were unloading a ship of salt. The ship was from South Korea and I was told by someone at the port that the salt came from plants in Saudi Arabia. I must have ASSumed it came desalination plants.
So, where does Saudi Arabia get their drinking water?
Saudi has a lot of Desalinization Plants. Maybe more than any other country. They tied the creation of them with a lot of power plants which is where I read a bunch about them.
But the output is saltier water. Removing all of the salt from a quantity of water is more complicated (expensive) than removing some clean water from salt water and sending the rest back as reject water. That reject water helps in a few ways, keeping a continuous process in liquid form that can be moved through pipes.
