Civic agenciesmay soon be able to get warnings about flooding in Bengaluru. The Karnataka State Natural Disaster Management Centre (KSNDMC), along with Indian Institute of Science (IISc), has come up with a sensor-based system which will alert the authorities and people living near flood-prone areas through text messages. The `7.5 crore project has been approved by the Union government.
In the BBMP limits, there are 633 storm water drains running to a length of 842 km. Of these, primary drains constitute 142 km and secondary drains run to a lenght of 426 km. The city drains can take 80 mm rain, but due to encroachment and poor maintenance, the capacity has been reduced to 35-40 mm of rain.
The Union Ministry for Science and Technology had invited various innovations. There were over 200 applications from across the country of which 19 were selected and ours is one them. The sensors will send them colour-coded alerts.
The sensors are fitted in the drain and the data can be read on another mounted equipment outside the drain. The mounted equipment works on solar energy.
