This document provides information on the Geographic Information System (GIS) implemented by the Bangalore Water Supply and Sewerage Board (BWSSB). It discusses how BWSSB developed a GIS in 1998-1999 through collaborations with other civic bodies. BWSSB's GIS system, called BISON, was developed by a French company and contains spatial and non-spatial data on water distribution networks, sewer lines, buildings, and other infrastructure across Bangalore. BWSSB uses the GIS for various functions like planning pipeline layouts, linking work orders to maps, analyzing water usage, and generating reports.

- 2. GIS • GIS stands for Geographic Information System • GIS is the merging of cartography, statistical analysis, and database technology. • It is achieved by combining software and hardware • Generally, a GIS is custom-designed for an organization.
- 3. GIS @ Banglore • BWSSB moved forward on developing a GEOGRAPHICAL INFORMATION SYSTEM (GIS) in 1998-99. • BWSSB and other Civic Bodies of BANGALORE (BDA , BMP & BESCOM) pooled resources for obtaining Aerial Photography of Bangalore from the NATIONAL REMOTE SENSING AGENCY (NRSA). • NRSA has supplied a photogrammetrically compiled Base Map to BWSSB covering an area of 290 Sq Kms.
- 4. • BWSSB under the Indo-French protocol in 1999 assigned the work of developing a GIS System to M/s SCE France. This led to the development of BISON (Bangalore Information System on Networks) applications for the operational activities of BWSSB. The GIS development was completed in the year 2002. • Genesys International Corporation Ltd, an internationally known, ISO 9001-2000, GIS and mapping company, has taken charge of Implementation and Maintenance of GIS at BWSSB w.e.f Nov 2003.

- 12. Attributes of Sewer Pipe
- 13. 1. Planning Pipe Line Layout GIS data is being used in Planning Pipe Line Layout for New Wards and CMC areas. Planning is carried out by identifying the main feeder line or near by reservoir or near by main sewer line to lay a new pipeline network for the new layout. Water supply network USE OF GIS in BWSSB
- 14. 2. Linking of L-Sections with GIS L sections can be seen in GIS by clicking on any segment on the Network data in display.
- 15. 3. Facilitating Complaint Management and Maintenance Work System is designed to cater to the need for addressing Complaints related to the Water and Sewage Network. The output from the System enables : a. Quick identification of Location from the digital map b. Better appreciation of the problem, as a holistic view of the network area is available. c. Connectivity with Service Stations provides speedy implementation of corrective action. d. A Database of all interactions is maintained and this serves as an input for periodic analysis and decision making at Apex Level.
- 16. 4. Thematic Analysis of Water Supply Distribution Water Connection patterns like domestic, non domestic,partial domestic, industrial etc.
- 17. 5. Water Quality Check Data on the results of Water Quality Testing, done at the BWSSB laboratory, is stored in the GIS for Analysis and Corrective action when required. SAMPLING POINTS
