The National Green Tribunal (NGT) has asked the Ulhasnagar Municipal Corporation (UMC) to divert a nullah to avoid the discharge of sewage and effluent from the Maharashtra Industrial Development Corporation (MIDC) area into the drinking water zone of Ulhas river. The tribunal, on Monday, warned UMC that in case of non-compliance within three months, it would give directions to the state urban development department to take control the affairs of Ulhasnagar and deal with problems of pollution in the area.
The Maharashtra Pollution Control Board (MPCB) had submitted an affidavit in the NGT, stating that of the total 90 MLD sewage generated from UMC, 10 MLD was discharged without treatment through Khemani nullah into the drinking water zone of Ulhas river, and the remaining 80 MLD sewage was directly discharged without any treatment through a local nullah into Waldhuni river.
The MPCB submitted affidavits on the sewage disposal methods of Ulhasnagar, Ambernath and Kalyan Dombivali municipal corporations. “It is explicit that some of the municipal sewage, ranging between zero to 80 per cent capacity, is discharged to Valdhuni river, Ulhas river and Ulhas creek, without treatment. Sewage treatment by municipal council or municipal corporation is totally unsatisfactory,” the tribunal observed.
The municipal corporations have failed to provide proper sewage waste disposal facilities, despite specific direction given by the high court to different authorities to deal with solid waste disposal. The tribunal deferred passing an order on this matter as the applicant, NGO Vanashakti, said they would file a contempt petition on this matter in the high court.
