The study is aimed to treat sewage flowing in open drains by application of especially developed microbial consortium – a bioremediation method. The objective of the study is that sewage may be stabilized in drains thereby giving relief to the citizens from exposure of obnoxious harmful gases and unhygienic situations which prevail in the vicinity of open drains, and to reduce concentration of water polluting parameters like biochemical oxygen demand, chemical oxygen demand, total dissolved solids, total suspended solids including odour control. The study has been carried out at Indore in Khajarana-RR-A.B. road drain in a stretch of 9.55 km as a model project using probiotics consortium without changing the basic structure of the drain or flow pattern, with a stress on economic-viability by adopting non- mechanized/ non-electrical processes so that unskilled staff could carry out the treatment process. A Critical examination of
Data for 12 months has shown reductions in odour of more than 98%, BOD of 75 to 80%, and COD of 70% under natural conditions.
