A drainage system for drying frac sand without heat comprises multiple layers through which liquid passes to dewater sand resting on the drainage system. At the bottom of the drainage system, perforated collection pipes, at least partially surrounded by rocks, collect the liquid and carry it to a collection pond for reuse. A cellular confinement layer comprises sections of panels which, upon expansion, have cells filled with rocks. A woven monofilament geotextile fabric layer comprising woven monofilament geotextile fabric sheets sewn together has sized openings which allow fluid, but prevent sand from passing through the openings. The top layer comprises perforated sheets of high density polyethylene welded together. A watertight liner sits below the perforated collection pipes and below the cellular confinement layer. Protective layers above and below the watertight liner prevent rocks from damaging the watertight liner.
