The Greater Bengaluru Authority (GBA) has launched a pilot project to address the recurring problem of blockages in covered stormwater drains, locally known as Raja Kaluves, which often lead to waterlogging and flooding during the monsoon. As part of the initiative, the civic body tested a state-of-the-art super-suction robotic machine to remove accumulated silt and sludge from stormwater drains in HSR Layout, Bengaluru.
