The Water Governance Institute’s aquaponics system contains a grow-bed for crops suspended over an aquaculture tank. The two components create a symbiotic environment where the nutrient-rich water produced by the fish is used to irrigate the crops, and the water draining into the tank is cleaned by the plants.

The product contains a grow-bed and a fish tank. The grow-bed is a 10-15 cm deep tray filled with a growing medium such as husks or loamy soil. Crops such as sweet pepper or tomato can be grown in the tray. The fish tank is filled with water that can hold fish such as tilapia. The fish tank can be sized at 1000 L, 9200 L, or 75,000 L to hold a maximum of 200, 1200, or 7500 fish. There is a spigot at the bottom of the tank that allows the user to drain water from the tank to water the crops. The grow-bed has a water-permeable bottom that allows wastewater from the crops to drip back into the fish tank. Additional water must be added to the system regularly to replace water lost through evaporation and crop transpiration.
