The idea is to arrest the entry of floating waste into the Hussainsagar lake. The boom barrier will be partially floating on the water surface and beneath as well. It will be installed at a strategic location to stop the floating material and later the accumulated waste will be collected and dumped into dumper bins through an automatic conveyor belt. The exercise of clearing the accumulated waste will be taken up every two to three days.

For the removal of floating material and shoreline cleaning across the lake’s 13 kilometre shoreline, the water body has been divided into six sectors in order to enhance level of cleaning and to have controlling, monitoring and accountability. Currently, removal of floating material in the middle of the lake is being done through floating trash collectors.
