Oshiwara river is one of four rivers of Mumbai we can call one of the life line of mumbai but it has been turned in to a nalla .I would request MCGM not to allow the sewerage line to be discharged in Oshiwara river it’s bad in law. We are continuously contaminating river as well as sea which is connected by this river all the ecosystems are damaged very badly. If we don’t act now the damage will be irreversible. MCGM and government should pass some stringent law by some punitive measures to ensure the sewage line are not connected and the river to be kept clean and also to barricade the boundaries of the river.
