Bangalore will need at least 2,550 MLD of water by 2040. Even if all the sources of drinking water are exploited, only 1,500 MLD of water will be available for the city. So, BWSSB (Bangalore Water Supply and Sewage Board) has installed bulk flow meters to monitor the flow of water in different areas and to check the wastage of water. The board is relying on GIS will help the department in checking the unaccounted for water. BWSSB has undertaken two major pilot projects to study the feasibility of implementing the system. One is expected to help the department, trace the leakages in the city through satellite imagery. If the plans are implemented according to plans, the harvested rain water is expected to meet the water requirements of the city for nearly six months in a year.
