HYDERABAD: With the delinking of Kukatpally nala from Hussainsagar, the Telangana State Pollution Control Board (TSCPB) has initiated steps to bring down the pollution level in the lake. The state pollution watchdog has procured two modern Real Time Water Quality Monitoring System (RTWQMS) for monitoring pollution levels in Hussainsagar.
The PCB, which has been regularly monitoring the pollution level in the lake had expressed concern over the steep rise in biochemical oxygen demand (BOD) in Hussainsagar. While the BOD needs to be regulated at 3 milligrams/litre (mg/l), the figures had shot up to 57 mg/l due to immersion of idols during Ganesha Chathurthi festivities in the city.
An equipment imported by PCB from Germany has been installed at an outlet of HS nala near BPP office few days ago, while another procured from Singapore is being installed at an inlet of Fatehnagar I&D site. These equipment will be connected to central data server in 10 days time for flow of constant information on pollution levels in the lake.
The new equipment would be commissioned on World Environment Day (June 5), N Raveendhar, TSPCB Senior Environmental Scientist, Central Laboratory, told Express.
TSPCB will install 10 such RTWQMS equipment at different points along Musi river, Durgam Cheruvu and Krishna and Godavari rivers to monitor pollution levels. The cost of each equipment is around `30 lakh.
The real time data collected from these equipment will be transferred to a central data server. The data server will be supported with the mechanism to feed raw data and processed data.
Limit and alarm values for the pollutants, would be feeded, and the calibrated data will be analysed and remedial action initiated to improve the water quality in Hussainsagar. The proposal is aimed at assessing the pollution levels and evaluate effectiveness of pollution control measures.
