Which brings us to the wetlands...this is where they recycle greywater--the household water that comes from the sink, or the washing machine--but never the toilet (that's called black water. We won't go there.). These stacked bathtubs have levels of gravel and then swamp plants that have the natural ability to filter water. The end result? More aqua for hydrating the crops.
