National Commission for Safai Karamcharis has been advocating machines in place of men to do the menial job.Manual scavenging was banned 25 years ago with the passing of the Employment of Manual Scavengers and Construction of Dry Latrines (Prohibition) Act, 1993, but it continues to find practitioners. The occupation persists mainly because of the continued presence of insanitary latrines. There are about 2.6 million insanitary latrines (dry toilets) that require cleaning by hand, according to Safai Karmachari Andolan, an NGO that works towards abolishing manual scavenging, and perhaps, the only one in the country, says a report in Down To Earth.

ML Prasanna Kumar, General Manager, HMWSSB, said the Bengaluru-based suppler has made changes and a demonstration was conducted again. The machine in its present state cannot be used in narrow lanes.

At present, HMWSSB is using 58 air-tech machines to clean the city’s 4.7 lakh manholes. A major drawback is that the machines cannot enter narrow lines. Officials have been hopeful of robotic-operated system which would make the process of cleaning the sewage easier. However, with the introduction of rover cameras and a robotic system, which comprises a robust cutting device and a screen to monitor the operations, HMWSSB plans to minimise manual scavenging and carry out the job with effective use of technology. Advertise With Us The Bengaluru company gave a demonstration on the concept at HMWSSB head office in June 2018 and they sought some changes in the machine. Even after a year, Sewerage Board is still awaiting supply of the system as the company has not completed adapting the device to Hyderabad environs. HOW IT WORKS The rover cameras are sent into sewer lines for identifying blockages, including tree roots, debris and sediments. The rover camera can tilt 360-degree and is connected with a 30-metre long wire. Its movement is controlled manually and can be tracked on a monitor. Soon after blockages are identified, Sewer Croc, a robotic device armed with stainless steel cutters, is dropped into the sewer lines. Mounted on a wheel-base, the sewer croc cuts and chops the accumulated waste in the lines with the blades. It is designed to make use of water supplied from a jetting machine to spin the turbine at high speed and cut the waste.TRAGIC INCIDENTS1.
