Shows a greywater recycling unit built for the course EES390 Sustainability Science taught by Professor John Ayers at Vanderbilt University. Dirty water from a dishwasher enters a tub filled with gravel and plants. Bacteria break down foodstuffs and the water provides nutrients to the wetland plants. Clean water exiting the tub can be used for watering gardens.
