Smart Water Control in Housing of UD

   Few days ago, Tejen Som, Special Engineer UD and his team successfully commissioned a smart water control system for Bichitra Abasan. This was based on a discussion with an IT expert several months ago at my chamber. The problem was that in Housings such as Bichitra Abasan the overhead reservoirs often overflowed while the lone pump operator tried to manage several tanks in several blocks. Sometimes the underground reservoirs would run out of water too but timely switching off may be delayed.

     The scheme that was commissioned is purely computer controlled. The engineer can start and stop all pumps in the Abasan from his laptop. Connectivity is provided through SIM enabled GPRS installed in a controller attached to each pump. There are sensors in the underground as well as overhead tanks. There is a microprocessor controlled mechanism that works out the logic and sends SMS message to the operator's mobile phone and the engineer's computer. If the operator does not respond within 2 minutes, the controller decides itself to switch off the pumps concerned.

      To cater to water supply problems, the water level in each of the eight overhead and underground tanks can be seen by sending a request from a laptop and getting a coded reply through SMS.

    To conserve water and wastage of power, the new smart system is a great help with manual warning and automatic cut outs. If the system works fine over a year, we will extend this to other Housing Estates operated by UD Department such as Sraboni, Falguni, Baisakhi etc.
