CapVal project financial flows
Figure presents the typical financial flow from a recently implemented model in Kumasi, Ghana. The main sources of revenue are from sales of African catfish, which exceed the operation and maintenance costs of the wastewater treatment plant. Treated wastewater can also be reused on-site to irrigate crops and fruit trees or for several other purposes. The volumes of sludge in small plants may not be attractive enough to engage in sludge recycling and commercialization. Also, carbon credits may be considered if the scale of implementation of this CEA and related savings are sufficient.
