Madurai City Corporation is one among the ten metropolitan cities in Tamil Nadu. Madurai city has two numbers of sewage treatment plants located one at Avaniyapuram and another at Sakkimangalam. This study aimed to characterize biological quality of the sewage water received (raw sewage water and treated sewage water) through Madurai Municipal Corporation. The fallouts of the research revealed that all the parameters of water analysis viz., Dissolved oxygen, Biological Oxygen Demand, Chemical Oxygen Demand, Total coliforms population were observed high in the water samples collected from raw sewage. Compared to raw sewage water samples, treated sewage water samples were observed high dissolved oxygen, low in Biological Oxygen Demand (BOD), low in Chemical Oxygen Demand and total coliform population. All parameters, recorded highest value during the season of summer among other four seasons and lowest value were registered during North – east monsoon season.
