BANGALORE, India: Bangalore Water Supply and Sewerage Board (BWSSB) has implemented GIS in the core city area. This is the biggest e-governance initiative of the Board and it will take another two years to complete the entire BBMP limits. The GIS will help BWSSB to store, access, query and analyse data, which in turn will help to take quick management decisions.
The BWSSB has been working on the GIS for the last seven years. So far, the board has updated all details covering the 229 sq km of the core city and is in process of dovetailing the GIS with revenue billing, employee database and other details. According to the BWSSB officials, the data related to the newly added areas of the city would be updated in the GIS by 2011. GIS performs four kinds of operations — data integration, data storage, data processing and data outputs. Data processing includes data viewing, data querying, data crossover and spatial analysis.
At present, 22 layers of information are available with BWSSB. The most important among them are water supply features like water pipes, valves, reservoirs, fire hydrants, and pumping and sewage features like sewers, manholes, connections in cross roads, consumers, administrative boundaries and BWSSB offices.
GIS provides solutions to implementing a sustainable and durable water supply and sewerage network management information system, and acquiring geographic description and analytical knowledge of BWSSB’s assets, both over ground and underground.
