The National Green Tribunal (NGT) in Pune has asked Trimbakeshwar Municipal Council here to complete separation of sewerage from river Godavari in the temple town by May 28 and set the same deadline for building a biomethanation plant to treat municipal solid waste. Hearing a PIL filed by environmentalists Lalita Shinde, Rajesh Pandit and Nishikant Pagare regarding pollution in Godavari at Trimbakeshwar on April 7, the NGT panel of Justice V R Kingaonkar and judicial expert Ajay Deshpande, sought to know from the TMC the status of separation of the river and sewerage. The civic body said work should be complete by first week of May. The panel granted the Municipal Council an extended period of 20 more days to complete the work by May 28. The NGT also sought to know the status of the bio methanation plant and set the same deadline for its completion. It also asked the Council to identify the blue line of Godavari in Trimbakeshwar by May 28. The three projects are particularly important keeping in mind the approaching Kumbhmela which will be held at Trimbakeshwar in\u00c2 July. According to mythology, the Kumbhmela revolves around the separation of Amrut - holy waters from the poisonous or unholy waters from the sea. "If we consider it in today's terms, the separation of the river and sewer signifies the same. If this is achieved in Trimbakeshwar (29 kms from Nashik)\u00c2 in the given deadline, then the holiness of the event will be preserved. This is the first step in making Godavari pollution free," Pandit said. In a related development yesterday, the Bombay High Court asked the petitioners to file a separate application on their plea to prevent people from taking bath down stream Tapovan Ghat and Dasak Sewage Treatment Plant (STP) on Godavari in Nashik during Kumbhmela. The HC was hearing a case of land acquisition for the proposed Pimpalgaon Khamb STP when petitioners Pandit and Pagare requested the court to consider prohibiting bathing on these ghats. The bench of justices Abhay Oak and A P Bhangale asked the petitioners to file a separate application in this regard. The petitioners told the court that bathing should be prevented considering that it could be dangerous to the health of people as foam is mixed with water down stream the STPs. Also bathing would further pollute Godavari, they said.
