Water Quality and its measure have turned into a genuine issue around the world. Release of used waters to the water bodies crumbles the amount and nature of the streams which causes significant sporadic attributes in the organic frameworks. Regardless of the way that stream can self-cleaning, on occasion contamination is done quickly and to a much higher degree that surpasses the breaking point of conduit to recover. Self-cleaning is the strategy which conform recovery of the water

Monthly samplings were taken and analysis was carried out for the parameters such as temperature, Dissolved Oxygen and Biochemical Oxygen Demand. Secondary data for these parameters were obtained through authorized Organisations for the period from 2004 to 2010. The study enables about the status of dissolved oxygen in the stream. It made a relationship between critical oxygen deficiency and the initial organic load disposed into the stream. The formulated relationships are able to assist the authorities concerned for urgent appropriate measures.
