Chief Minister also launches the ‘Clean Hussainsagar’ campaign
As part of a year-long initiative to get rid of pollutants from Hussain Sagar Lake, dredging work at the water body was initiated on Friday.
The massive exercise launched by the Chief Minister, N. Kiran Kumar Reddy, will help to scoop out sediments to the tune of 10 lakh cubic metre from the confluence points of four inlets of the lake.
The dredging of sediments at three inlets, Balkapur nala, Picket nala and Banjara nala, has started while the work on Kukaptally nala confluence point will be initiated at a later date since sediments here were found to be hazardous.
One of the major aspects of the Hussainsagar Lake and Catchment Area Improvement Project, the exercise would have the dredged out sediments dried and shifted to existing quarry pits at Jawaharnagar dump yard.
The lake, which has been polluted due to untreated sewage and industrial effluents generated in the catchment of 240 square km through the four inlets, is being restored with the assistance of Japan International Cooperation Agency (JICA) to the tune of Rs. 370 crore.
Apart from dredging work, the Chief Minister on Friday also launched the ‘Clean Hussainsagar’ campaign, commissioning of upgraded tertiary level 20 MLD STP at Khairatabad and the 1400 mm Balanagar sewer main.
Reuse of water
The STP has been upgraded to the tertiary level and according to HMDA officials, the treated water would be processed for ultra-filtration by membranes procured from Australia.
The water then gets disinfected of pathogenic bacteria to achieve a quality, which the officials described would be fit for reuse, for non-potable purposes.
Speaking on the occasion of the launch, the Chief Minister called for a concerted effort involving all stakeholders to clean Hussainsagar Lake.
Efforts are on to clean and restore several other smaller water bodies in the city and tough action is in store for those taking up illegal constructions alongside them, he said.
In his address, Labour Minister D. Nagender said the HMDA should not remain mute in issues that threaten the lake and cautioned senior officials of action in case they failed to take steps needed to protect the water body.
