Water quality is relative and its characteristic influences the suitability for a specific use. Drainage water is not different from any water supply since it’s always usable for some purpose within certain quality ranges. Drainage water that flows over or through the soil will pick up a variety of dissolved and suspended substances including salts and organic compounds. Management for safe re-use and disposal requires an understanding of the characteristics of the drainage water, and a matching of those characteristics to the environmental protection needs of the re-use or disposal area. Water samples for Physio-Chemical analysis are collected from 21 non point sources. The drainage system extends from Indrahali temple to Malpe beach. The analysis were done for the parameters such as pH, Conductivity, Total Dissolved Solids, Turbidity, BOD, COD, MPN, Chlorides, and Hardness. The results indicates that for certain points chlorides and hardness are exceeding the permissible limit due to domestic waste disposed to the drainage system. Due to disposal of waste water from STP which is located near the Drainage system, BOD and COD values are also high.
