Sewage is mainly composed of human domestic wastes including wash-water , fecal material, and industrial wastes. The growing environmental pollution needs for decontaminating wastewater result in the study of characterization of waste water both for domestic sewage and industrial sewage . Recently, increasing pollution in the waste water and updated criteria for disposal, leads to developing and implementing new treatment techniques to keep the parameter of sewage within the present permissible limits .Sewage Treatment Plant is a facility designed to receive the waste from domestic, commercial and industrial sources and to remove materials that damage water quality and compromise public health and safety when discharged into water receiving systems. It includes physical, chemical and biological processes to remove various impurities depending on its constituents. The present study comprises the study on quality of waste water that is discharged from the domestic and industrial outlets . The present study is to make treated sewage as per the latest codal provisions . The study includes characterization tests for pH value, acidity, alkalinity, chloride, residual chlorine, turbidity & DO , the retrofitting of plant and calculation of parameter of treated sewage .
