The present research deals with the study of physico-chemical and bacteriological characteristics of sewage water collected from three different sites of treated pond during two consecutive seasons. Seasonal variations indicated that the most of the nutrients (viz., total N, phosphates) and salts (nitrates, chlorides and sulphates) are present abundantly at winter and the physical characters like TDS (600 mg/L) are more at summer seasons. The pH meter (Elico� LI 20) and EC meter are calibrated with pH buffer(4.0, 7.0 and 9.2) and saturated KCl before taking the reading. Dissolved oxygen (DO), Biochemical oxygen demand (BOD), Chemical oxygen demand (COD), Total dissolved solids (TDS), Total suspended solids (TSS),Total alkalinity (TA), Nitrates (NO3), Sodium (Na), Potassium (K), Calcium (Ca), Magnesium (Mg), Chlorides(Cl-), Sulphates (SO42-) were analyzed Multiple comparisons made using analysis of variance showed that the treated sampling pond point varies significantly from other two ponds and Raw sewage. The total coliform count for the treated samples were >2400 (MPN/100ml) in raw sewage. This study concludes that the physicochemical characters and microbiological characters are outrageous in the raw sewage and upon the treatment the undesirable characters are reduced. Studies on the sewage characteristics of treatment plants are crucial to know the pollutant levels upon the various time scales and the treatment status which is necessary to improve the state of the art of the treatment process.
