Government on Thursday exuded confidence in Lok Sabha that Ganga would be cleaned by July 2018 and said the return of aqua life in the river would be the biggest benchmark to prove that it has been rejuvenated and efforts towards its cleansing have succeeded. Responding to a series of supplementary during Question Hour, Water Resources Minister Uma Bharti said she would announce in the House in July 2018 that the river has been cleaned and rejuvenated. She said the return of river dolphins, turtles and gold fish in the Ganga aqua life system would be the biggest benchmark to prove that the river has rejuvenated. Bharti said the cleanliness of a river cannot be established in a lab where quality of packaged drinking water is established. Samajwadi Party supremo Mulayam Singh Yadav suggested that the drainage system of cities should be reworked to ensure that the waste goes to the fields and not rivers. He said it would provide farmers with fertiliser and save rivers from pollution.
