The Hyderabad Metropolitan Water Supply and Sewerage Board will use the latest technology to detect the health of its sewer network. The water board has been maintaining the 6,780-kilometre sewer network in the city. To start with, the water board would use robotic CCTVs and acoustic profiler to study the 18.8-km length of sewer trunk main between Jeedimetla and Amberpet sewage treatment plant, which was laid in 1993. The water board currently has no mechanism to assess the condition of the sewer network. With industrial units generating 184 million liters per day (MLD) of effluents and residential colonies adding to the load, the water board was not able to take up maintenance of the trunk main.
“Initially, the six-km sewer line between Jeedimetla and Hotel Marriott will be assessed. The robotic CCTV will take images of the trunk main, while the acoustic profiler will look for defects in the pipeline,” the official added.
