Inside the greenhouse, water first goes to the Subsurface Wetlands, then to the UV light, and finally to the Free Surface Wetlands.
This completes the cleaning process. Finally some water is used by a fish pond inside of the greenhouse, some is used to water more plants inside the greenhouse, and some is discharged to a rain garden outside.
Follow the water: Source---> Septic Tanks --->Recirculating Filtration System---> Greenhouse (Subsurface Wetland, UV Light, Free Surface Wetland) ---> Discharge Site
