The Tumkur city sewage samples were collected and analysed from February 2007 to January 2008 for six sampling points - residential area (S1), business centre (S2), slum (S3), converging point (S4), open drain (S5) and treated sewage water (S6). The correlation coefficient ‘r’ of some physico-chemical parameters is derived. There is wide variation in the sewage quality, which is reflected by the results. The usefulness of this approach has been demonstrated to predict the quality of domestic waste. The result of the study is useful to predict the anthropogenic activities of the area. The present study reveals the significant correlation among pH-alkalinity, electrical conductivity-total dissolved solids, hardness- chloride, BOD-COD, although the quality of sewage varied significantly. The study of correlation coefficient facilitates the rapid monitoring process of sewage and gives an idea of treatment technique.
