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.

10. DATA AVAILABLE IN GEO-DATABASE AT BWSSB
Spatial Data
•Road Network & Road Names
•Base map of Buildings, Green area &
Landmarks
•Consumers
•Location of Service Station
•Details of water supply network
•Details of sewer network
•Location of BWSSB Offices
Non-Spatial data (eg.)
•Attributes of water network
•Attributes of sewer network

11. INFORMATION AVAILABLE IN GIS AS ATTRIBUTES
Attributes of Water Pipe

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.

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.
