The document discusses the implementation of a GIS system at the Bangalore Water Supply and Sewerage Board (BWSSB). BWSSB assigned development of a GIS system called BISON to France in 1999. BISON supports BWSSB's operational activities. Genesys International Corporation took over GIS implementation and maintenance in 2003. The GIS contains extensive spatial and non-spatial data on water supply networks, sewer networks, buildings, and other infrastructure. Examples are given of how GIS supports functions like pipeline planning, complaint management, water quality monitoring, and statistical analysis. Recommendations are made to enhance the GIS system.

PRESENTING : A CASE STUDY ON GIS APPLICATION IN
BWSSB (BANGALORE WATER SUPPLY AND SEWERAGE
BOARD)
GROUP: 8
MADE BY :
AXAY SHARMA (20MCL002)
HITESHREE MITHAIWALA (20MEN006)

GUIDED BY : PROF. DHRUVESH PATEL

2. •BWSSB (Bangalore Water Supply and Sewage Board) under the
Indo-French protocol in 1999 assigned the work of developing a GIS
System to 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.
• It is the governmental body responsible for supplying water to all
areas in the city.
•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.

13 000 Valves,
3 000 Employees,
4 000 Water Pipelines (Km),
3 000 Sewage Lines (Km),
300 Fire hydrants,

Amount of records in BISON

6. 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:
•Attributes of water network
•Attributes of sewer network

7. 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.

Use of GIS in BWSSB (Examples)

8. 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.

9. 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.

10. 4. Thematic Analysis of Water Supply Distribution
Water Connection patterns like domestic, non domestic, partial domestic, industrial etc.

11. 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

12. An example - Statistical report on length of pipe lines for the city of Bangalore.The
statistics show the lengths of pipes for both sewer and water, Service Station wise.

13. List of functional areas of BWSSB for which a monthly report is generated

14. Complaints related to Leakages

15. Domestic Water Consumption

16. Reccomendations for enhancement of GIS
•WEB Hosting of GIS on intranet/internet.
•Online registration of consumer complaints and linking with GIS through
Internet.
•Providing ortho-imagery (from satellite / aerial) as background.
• Draped DEM attached to Maps, providing a better perception of Ground
for Engineering Planning (New Connections, Network Planning,
Replacements/Repairs).
•Contour map generation from DEM to assist (Sewage route planning /
Laying of Storm water drains, Network Planning , etc.)
• Connectivity with other civic bodies to share related information
• GIS on a Hand held device
