The present study demonstrates the assessment of sewage quality of two residential areas and two public parks in Nagpur. The sites were chosen considering freshwater demand for non-potable purposes by small communities. Grab samples of raw sewage were collected and analyzed for physicochemical parameters such as pH, alkalinity, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Total Kjeldahl Nitrogen (TKN), Total Phosphate (TP) and faecal coliforms (FC). The raw sewage of all sites was found to be of moderate strength with an average COD of 250 mg/L, BOD 150 mg/L, TSS 200 mg/L, TKN 25 mg/L and TP 3 mg/L. Baseline data was also generated for groundwater samples of the sites under study. Based on the results, various treatment options were proposed comprising natural treatment by wetlands for removal of organics and nutrients, polishing treatment by granular activated carbon for removal of trace contaminants e.g. Pharmaceuticals and personal care products and finally disinfection of the treated effluent to be reused for non-potable purposes.
