In addition to this natural scarcity of freshwater, the quality of the available freshwater in many developing countries is equally deteriorating as a result of pollution (Kivaisi, 2001).

Furthermore, inadequate energy supply and pollution have been reported as major challenges in Nigeria(Owamah et al., 2014a,b; Dahunsi et al., 2014).
