Abstract—This study on the effect of solar and hydraulic jump on waste stabilization pond aims at determining increase in solar radiation with hydraulic jump on treatment efficiency in wastewater. In this study, WSPS with varying sizes and steps were constructed using metallic tanks with inlet and outlet valves. The steps enabled the introduction of hydraulic jump. The hydraulic jumps were created to introduce turbulence thereby adding dissolved oxygen in the pond. Also, the solar reflectors were constructed to increase the incident sunlight intensity. Wastewater samples collected from the outlet of the IWSP was examined for physiochemical and biological characteristics for a period of Eight weeks. The parameters examined are temperature, pH, detention time, dissolved oxygen, faecal coliform, Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). This research revealed that the cost of wastewater treatment by using solar reflector and hydraulic jump (steps) enabled WSPS was approximately one and a third lower than the conventional WSPS
