The apparatus includes a tank influent stream for passing water through the plant material zone and subsequently through the animal raising zone. The system includes a recycle loop having a pump disposed within the animal raising zone for pumping a waste product from the animal raising zone to the irrigated plant material platform. The animal raising zone may be a fish raising zone.
