In most urban cities, domestic wastewater, especially black and greywater, is discharged into the environment untreated. This results in contaminated surface waters and underground water sources. They seek to solve this problem by recovering nutrients from the wastewater for fish culture and revenue. The short-term plan of TAC is to embark on full-scale commercial production (6,000kg/year) of the fish after which the business model could be replicated in other potential sites in Ghana and other African countries to sustainably address sanitation.
