Water is the basic necessity in almost all type of cooking, washing&daily routine activities for healthy life but everyone is involved intentionally or unknowingly in activities creating water pollution.The soil condition particularly agricultural fields containing excess fertilizers/pesticides /harmful constituents responsible for soil contamination and both biodegradable / non-biodegradable wastes thrown or lying on the ground in the course of river/drains/streams are the human activity causes of river pollution and shares the maximum contribution in context to river water pollution in addition to the natural causes for water pollution such as earthquake,landslide,flood,T-Sunami,volcanic eruption etc. Disposal of domestic waste at the banks of water bodies or solid waste disposed at the sides of roads and streets though contains smaller quantity of the pollutants/contaminants but plays a big role in the pollution of first strata water & river water through surface drains or city sewers dropping intoriver.The present evaluation study is concerned not only with the problems in the implementation of measures adopted to control the river water pollution but also the statistical /comparative analysis of the five main city sewer streams/river water quality in light of parameters length of stream, dropping discharge per day, potential hydrogen (pH), biochemical oxygen demand(BOD),chemical oxygen demand(COD), total suspended solid(TSS),total Coliform (T Coli.)
