Figure 1: Experimental Setup. The overhead storage tank (1.2m×1.5m×1.5m) was usually filled intermittently with sewage from the University of Nigeria, Nsukka, Nigeria facultative WSP through an underground pipe with a pump. The sewage storage tank (1.2m 0.5m×0.5m) gets its supply from the overhead storage by gravity flow through a pipe connecting both. Both tanks were usually filled to supply the three ponds with sewage wastewater. The samples were collected at an interval of twice per week from the three ponds for ten weeks. Samples were collected from one pond at a time. For Pond 0, samples (0a and 0b) were collected at both the inlet and outlet. The wastewater flows into the experimental ponds through an inlet (19mm diameter) pipe. The wastewater flows out of the pond through a slit. For Pond 1 and Pond 2, five samples each were collected at intervals of 160mm at different points along the channels. These points corresponded to 1a, 1b, 1c, 1d, 1e, 2a, 2b, 2c, 2d and 2e for Pond 1 and Pond 2 respectively. Thereafter, samples collected from the three ponds were taken for laboratory analysis to determine the concentration of BOD, COD, total Coli form and Dissolved Oxygen. Date of collection of sample was recorded for the duration of the research.
