Clean sand is stockpiled until it can be loaded into trucks for final sorting and drying off-site. (Some mines sort and dry sand on-site rather than sending it out.) Because the sand still contains moisture when it is stockpiled, drain tiles beneath the piles channel water to a lined process-water pond.
