aggregate washing is mostly recirculation of water - you can increase the proportion of recirculation right away (without having to wait for ponds to develop a seal on the bottom) with equipment such as a slanted plate clarifier or thickeners made to recycle slurry water prior to settling ponds with the use of flocculants. A concentrated slurry goes to the pond and much of the water is immediately available for reuse. if there is concern from MECP about the volume that would be taken from the aquifer vs recirculated one could require this type of equipment.
