They've been talking about desalinization here as long as I can remember...since the 60s at least. One big issue is expense, and another is pollution. Desal plants use a lot of energy, and they create salt flats that damage the environment.

A series of air wells would passively pull large amounts of moisture directly from the air, to be added to reservoirs or pumped directly to where it will be used. Air wells are ideal for a desert climate where they can be placed to take advantage of convection currents. If it'll work in Iraq, it will produce water anywhere.
