Supreme Court on Wednesday said Ganga cleansing programmes have been going on for over three decades with almost no impact on the ground and wondered whether the government wanted to do something during this tenure or would it spill over to the next term. The apex court sought fresh response of the government about the steps undertaken by it to implement the stage-wise projects for cleaning the Ganga in the states of Uttarakhand, Uttar Pradesh, Bihar, Jharkhand and West Bengal in six weeks.

"Now the point is, it is going on for last 30 years. You (Centre) tell us as to what is the verifiable progress in this regard," a bench headed by Justice TS Thakur said when the counsel for the Centre submitted that "things are happening".

"118 more towns have been identified by this government. Things have started moving. They (municipalities and other concerned authorities) have been told to wake up," Solicitor General Ranjit Kumar submitted before the bench that also comprised justices R K Agrawal and Adarsh Kumar Goel.

The bench, which had earlier asked the Centre to come out with a "stage-wise plan" to clean the river, sought additional specific response on 70 sewage treatment plants, which are at various stages, likely to come up in the five Ganga basin states.

"If you have financial problem, we cannot solve. All that is required is that you go ahead with the projects and if there is any bottleneck, you can come before us. "Don't take it (PIL) as an adversarial litigation. Do you want to say that this has to be done during this government or in the next term of the government," it asked.

Soon after, the court's remark, the Solicitor told the bench that "This government will complete the cleaning by 2018."

The bench also noted Kumar's submission that the consortium of seven IITs was expected to address the issue relating almost 100 km-long eco-sensitive zone ranging from Gomukh to Uttarkashi.

Earlier, the court said it was not happy with Centre's blueprint to clean river Ganga but had sought response on how it plans to implement the ambitious policy.

The Modi government had placed before the court a blueprint of short, medium and long term measures involving thousands of crore of investment to restore the glory of the holy river.
