BMC will now take help of robots to clean British era underground drains, from January. This step to prevent water logging, is expected to yield positive results.
Cleaning of these drains has always been a problem as these also run under buildings and neither be cleaned easily nor its possible to widen or deepen these. The British era drains have a carrying-capacity of 25mm per hour.
The civic body will spend Rs 60 crore over a period of two years for the robot
to be used from January 2019.
At the municipal commissioner’s review meeting on Monday, officials said they plan to have a remote-controlled robot, mounted with camera, that will remove silt from the drain and put it into a recyler machine. “On the monitor we will be able to see how much silt has been removed,” said a civic official adding that preparation for the works to be undertaken would start on December 15 while actual works on ground will start from January 1. An official said the BMC would not own the robot and that a contractor will procure and operate it.
As a part of its pre monsoon works, BMC takes up cleaning of drains across Mumbai from January to May every year to ensure smooth flow of rainwater. However all previous attempts to mechanically clean the drains have failed miserably.
