Ok some of the Permiculture group have come up with something for grey water called a banana circle. I am modifying it to make a banana trough. Anyway my plan is to have my house plumed with black water going to a standard septic tank run through an artificial wetland then into a surface pond with    Acai Palms around it. The grey water will be surface discharged into troughs surrounded by Plantains. Then I can make sure my plantains have enough nutrients.
