DM Sharma told that the encroachments over five water ponds situated in the city were removed and unauthorised constructions were demolished near Arthala village lake.
A PIL was filed by activist Sunil Ragav before NGT in December 2014 requesting for removal of encroachment from water ponds and government lands in the city.
Taking cognizance of the PIL, the tribunal had directed the state government and its Chief Secretary to file a status report in the matter, he said.
Next date for hearing in the matter has been fixed for 17th August, Sharma added.
