Performance Evaluation of WupaBasin Sewage Treatment Plant in Abuja, Nigeria

Improperly disposed wastewater has been a major source of environmental pollution which is a challenge and of public health concern in developing countries such as Nigeria.The quality of human health and its environment is directly linked to wateruse and wastewater management. This study aimed atassessing the performance of the Wupa Basin Sewage Treatment Plant in Abuja to ascertain its efficiency in compliance to National Water Quality Standards for discharge into the environment.Samples were collected from the treatment plant and analyzed for parameters such as pH, BOD5, COD, DO, TSS, NO3-N, PO4-P, NH4-N and Total coliformfor 2 years. The plant was generally efficient in treating influent received with average performance efficiency of 91.70, 91.62, 87.65 and 87.27% for TSS, Total coliform, BOD and COD respectively amongst other measured parameters. Aside the significant difference observed in influent and effluent, the final effluent concentrations were all within the WHO and NESREA permissible discharge limits.The treatment plant is of high efficiency as it provides adequate treatment for received wastewater.
