1. PRESENTATION ON APPLICATION OF GIS IN BWSSB
ON THE OCCASION OF WORLD WATER DAY
By the GIS Cell of BWSSB

2. INTRODUCTION
General
BWSSB moved forward on developing a GEOGRAPHICAL INFORMATION SYSTEM (GIS) in
BWSSB and other Civic Bodies of BANGALORE (BDA , BMP, BESCOM AND OTHERS) 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.

3. INTRODUCTION contd
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 , GIS and mapping company, has taken charge of Implementation and Maintenance of GIS at BWSSB w.e.f Nov 2003.

5. GIS SETUP IN BWSSB contd..
BWSSB Head Office is connected to all its Divisional Offices through LAN/WAN
The GIS Hardware/Software setup at BWSSB is as below:
Hardware / Software
Head Office – One Server with 5 PIII workstations, One Plotter,
Scanner and A3 Colour Printer, with ArcInfo 8.1, Arc SDE (Spatial Database Engine), ArcView 8.0, ArcPress and Oracle 8i RDBMS
Divisional – One Server with 2 PIII workstations and A3
offices Printer, Software - Arcview 3.1 and Oracle
RDBMS
Service Stations – One Desktop PC with Printer

Employees,
Water Pipelines (Km),
3 000 Sewage Lines (Km),
300 Fire hydrants,
103 Reservoirs,
73 Offices,
48 Pumping Stations.

9. DATA AVAILABLE IN GEO-DATABASE AT BWSSB
Spatial
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

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

11. Attributes of Sewer Pipe

12. USE OF GIS in BWSSB (Examples)
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

13. 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.

14. 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 :
Quick identification of Location from the digital map
Better appreciation of the problem, as a holistic view of the network area is available.
Connectivity with Service Stations provides speedy implementation of corrective action.
A Database of all interactions is maintained and this serves as an input for periodic analysis and decision making at Apex Level.

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

16. 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.

17. MIS EMBEDDED IN GIS STATISTICAL REPORTS CONSUMERS COMPLAINTS
MAINTENANCE
MANAGEMENT INDICATOR PANEL (MIP)

18. 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.

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

20. COMPLAINTS RELATED TO LEAKAGES

21. DOMESTIC WATER CONSUMPTION

22. LIVE APPLICATION OF
(BISON LIGHT)

23. RECOMMENDATIONS 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

25. GIS ON A HYBRID DATA
A hybrid data set on an Ortho photo is more meaningful as we are sure of what we are querying.
Hybrid data involves
house and location pictures
Videos
Voice
etc
