ABSTRACT
Worldwide unsystematic and untreated disposal of wastewater is the biggest challenge to environmental scientist and engineers. This problem started long back but intensified during the last few decades, and now the situation has become alarming in India [7]. During the past three decades, the effects of municipal wastewater and effluents, the point source pollution, on the water quality of canals, streams and rivers have received some attention but very little attention has been reported about the sewage water quality of the receiving water bodies. The input of
large quantities of nutrients mainly nitrates and phosphates in to river waters caused eutrophication and its related effects [9]. These nutrients particularly phosphorus is often the limiting nutrient in such systems [13]. Sewage effluent containing sulphate may produce hydrogen sulphide that in the form of sulphur is poisonous; so the untreated sewage should be treated in the sewage treatment plant (STP) before letting into the receiving water bodies.
