Additionally considerable quantities of subsoil brines existing in such basin water tables would ensure brine supplies, as is demonstrated by the new potash plants in the Tarim basin using the ancient Qanat technology.

The surface crust of an inland Sabkha endorheic basin typically is made up of layers of salts that have re-crystallized and settled or precipitated during the evaporation process of controlled Qanat system flood waters.

The qanat technology was developed in ancient Iran by the Persian people sometime in the early 1st millennium BC, and spread from there slowly westward and eastward.Qanats are constructed as a series of well-like vertical shafts, connected by gently sloping tunnels.Qanats efficiently deliver large amounts of subterranean water to the surface without need for pumping.The qanats are constructed mainly along the valleys where Quartenary sediments are deposited." The original ancient engineered design of the Qanat and its multiple aligned bore-holes are thought to have controlled desert endorheic basin flooding without destroying the salt mirror playa or causing erosion of the flat evaporation fields.The Qanat water was primarily needed to extract salt, rather than for simple domestic irrigation.
