  6. Chronology of LWS GIS Development

  7. Location : 8 km West of Sabah Area : 90 km.square Year 2000 GIS Data Population : 50,000 No. of Connections : 10,000 Daily Demand : 22,730 m3/day Total Length of mains : 350 km

  8. Year 2012 GIS Data Population : 80,000 Nos of Connections :14,847 Daily Demand : 54,000 m3/day Total Length of Mains : 540 km

  9. GIS DEVELOPMENTS 1996 – 2004 (ALL CUSTOMIZATIONS WITHIN ArcVIEW PROJECT FILE)

  10. PROCUREMENT BASE MAP, DATA CAPTURE OF PIPES, SLUICE VALVES, HYDRANTS, PIPE ENDS. WATER METERS ETC. LAYANGAN

  11. Creating Relational Database (using ArcView 3)

  12. GIS DEVELOPMENTS 1996 – 2004 • JKR Labuan.apr an ArcView project file had been customized to perform the following functions. • FILING SYSTEM • MAP PRODUCTION • LEAKAGE RECORDS REGISTRATION • HYDRAULIC ANALYSIS & MODELING

  13. CUSTOMIZED POP OUTS FOR FILE LINKAGE FILING SYSTEM – LINKING SHAPE FILE

  14. LINKING AUTOCAD FILE LINKING VIDEO FILE LINKING IMAGE FILE LINKING TEXT FILE

  15. FILLING INFORMATION MAP PRODUCTION

  16. PREVIEWING & EDITING MAP PRINTOUT MAP PRODUCTION

  17. LOCATIONS OF LEAKS/BURST REGISTERING PIPE’S LEAKS/BURST RECORDS

  18. INSERTING NEW RECORDS REGISTERING PIPE’S LEAKS/BURST RECORDS

  19. LEAKS/BURST ATTRIBUTES LEAKS/BURST RELATIONAL DATABASE

  20. Pipe Hydraulic Simulation & Modeling Assemble to form pipe network ( 2 ) Assign Elevation Data To Pipe Fittings & Demand Nodes ( 9 ) GIS Pipe Database ( 1 ) Proofing of Network With on-site inspection ( 3 ) Initial Pipeline Model ( 5 ) Update GIS Database ( 4 ) Insert Flow Pattern ( 10 ) Carryout Hydraulic Simulation ( 11 ) Assign each meter consumption To Demand Node ( 8 ) Calibrate & Validate Model base on Measured flow & pressure ( 13 ) Field’s Measurement ( 12 ) Calibrated Pipeline Model Update and Check Metering Database ( 7 ) Create Demand Node & Demand Polygon ( 6 ) 14. Customized All the Above into Labuan GIS

  21. Pipe Hydraulic Simulation & Modeling

  22. WARIS-DATA Updating View WARIS Tool Menu Hydraulic Simulation Customization

  23. EXPECTED BENEFITS OF NETWORK MODELING Distribution Study Done In-House Tool for Troubleshooting Network Problems External Linkage With SCADA System For Network Modeling Quick Assessment Of Distribution System Pipe Flow/Pressure NETWORK MODELING Ensure Minimum Water Quality by Network Simulation Efficient Water Supply Distribution Locate Areas of Low Pressure For Upgrading Planning For New Supply Areas Other Research Studies

  24. YEAR 2009- 2012 UPGRADING OF LWS GIS & CREATION OF AN INTEGRATED MANAGEMENT SYSTEM FOR NRW CONTROL USING NETBASE 10/21/2019

  25. Scope of Works • Upgrade & update Existing GIS • DMA Design & Construction • Hydraulic Modeling Using Infoworks • Integrated Water Distribution Management System Using NetBase • Recommendation for Consumer Meter Replacement • Active Leakage Detection

  26. GIS System Upgrading • Supply & install ArcGIS Software (ArcGIS Server, ArcEditor & ArcView). • Purchased new Cadastral Base map • Purchased Satellite Image • Updated Pipe Registration (added 137 km pipes) • Geo-Coded all 14,800 consumer meters.

  27. An Integrated Water Distribution Management System Using NetBase • Integrated with Logger & Telemetry System • Water Supply Input Flow-meters at WTP & Import Terminal Reservoir Outlet time series data • DMA Flow and Pressure time series data • Storage Tanks Level time series data • Integrated with Corporate Data Sources • GIS System incl Pipe Registration & Consumer Geo-Coding • Consumer Billing System • Hydraulic Modeling

  28. Netbase Concept Corporate Data Sources Required for Supply, Demand Balance & Leakage Add for Modelling, AMP, LOS Netbase
