Pune is blessed with mula and Mutha River that originate in the Sahyadri range. Mutha River is one of the most polluted water body in India. The river covers the rural area of Pune in the initial stage hence it receives agricultural runoff in large proportion, the disposal of waste, hospital and industrial effluents etc. In this river is treated like open drain by the citizen who discharges raw sewage and industrial waste hence, DO, BOD, and COD is affected. The aim of the project is to improve the existing condition of the river and make them more accessible for the people. Therefore ,providing non-mechanized treatment to the river flow by providing baffles with alternate orifices of different sizes to increase the contact of river water to the atmosphere. With the help of this, self- purification can be achieved.
