Primary treatment: water purification and impurities are removed by sand filters.

Reverse osmosis treatment stage: The water is transferred after it leaves the primary treatment stage by high-pressure pumps to the final stage of treatment in order to skin the dissolved salts with reverse osmosis technology by reverse osmosis membrane units, after which the final product is calibrated according to the Saudi international standards to complete the production stages, and then the produced water is pumped to the tanks of the final product, where the car tanks are filled with them for distribution to consumer use points.
