Over 20,000 crores has been spent on cleaning several of India's rivers but to no avail. 7,000 million litres of untreated sewage every day is disposed in the Ganga. The pathetic state of all of India's rivers is a cause of concern as almost all of India's major rivers. The Ganga and Yamuna remain two of the world's dirtiest rivers and despite several conservation efforts, the status of these two rivers has kept deteriorating.
