  2. Water supply

  3. ESRI DM for water supply networks • Comprehensive • Customizable • Flexible • Scalable • Universal • Extensible • Distributed • Part of Arc suite

  4. ESRI DM for water supply networks • Composed of four basic components • Features • Equipment • Line • Facility • Uses geodatabases for defining objects and behavior in network

  5. ESRI DM for water supply networks Inheritance model Example

  6. ESRI DM for water supply networks • Features are spatial entities that do not participate in the active network • Equipment are the features in a water or wastewater system that do not have an associated geometry or position

  7. ESRI DM for water supply networks • Facilities are used in transmission and distribution of water and are commonly used to join various water lines together   • The assorted types of pipes used in the transmission and distribution of water are generically termed lines

  11. ESRI DM for water supply networks

  12. Case studies

  13. Elsinore Valley Municipal Water District • Detailed inventory of all assets • Database of water facilities • Data handled by 15 departments • Uses SQL Server as back-end and Visual Basic based application as front-end

  14. Elsinore Valley Municipal Water District • Finance department • Standby assessments • Pressure zone charges • Reimbursement agreements • Location of facility assets and link to customer account information to determine connection fees

  15. Elsinore Valley Municipal Water District • Operations department • Creation of atlas maps, facility locations, asset maintenance and replacement, and assistance with DIGALERT Calls system • Customer service department • Meter reading route analysis • Meter location determination • Identification of illegal connections

  16. Elsinore Valley Municipal Water District • Engineering department • Verification of water availability, planning, inspection assistance, and generation of drawings for internal projects

  20. City of Germantown, Tennessee • No digital maps and database • Drought-affected and frequent water shortages • Water purchased from adjacent counties to meet demand • Water data on 1:500 scale conventional maps

  21. City of Germantown, Tennessee • Uses ArcGIS Water Utilities Data Model • Digital orthophotography for planimetric data compilation • Minimal customization performed on ArcGIS Water model • Database design completed in a short period

  22. City of Germantown, Tennessee • Data created as shapefiles • Shapefiles incorporated in geodatabase • Update of model made easier • Demand information obtained from CIS and DTM of the city • Elevated storage and larger diameter line needed for meeting peak demand

  24. City of Germantown, Tennessee

  25. Colorado Springs Utilities • Provider of water, gas, electricity and waste management services • Unification of services proposed • Basemaps originally created from orthorectified aerial photographs • High-resolution maps needed • Imagery processed using ERDAS s/w • Maps incorporated in ArcINFO GIS

  26. Colorado Springs Utilities • Information generated • Detailed maps • Accessibility • Maintenance history and schedules • Future water needs • Land-use monitoring • Obstacles and no-go zones

  27. Colorado Springs Utilities • Change in irrigated land using infrared photographs incorporated into existing GIS

  30. Electricity supply networks

  31. PDA DM for electricity networks • Origin GIS Data Model • Industry standard • Developed by Power Delivery Associates • Origin GIS works in conjunction with ArcGIS 8.3 • Based on MultiSpeak interface

  32. PDA DM for electricity networks • Robust data model tailored to the needs of electric utilities • Sophisticated electrical rules base to ensure bulletproof system modeling • Customized graphical user interface to ArcGIS 8.3 for data creation and modification • Customized user interface for map plotting

  33. PDA DM for electricity networks • Full electrical connectivity from substation to meter • Extensive tracing and spatial query capabilities • Interface/Integrate with leading software providers • Easily publish maps to Internet or other viewers • Push-button switching for easy connectivity model changes

  34. PDA DM for electricity networks • Object-oriented data model • Components of data model • Network features • Non-network features • Object classes • Object classes composed of several classes interacting with other components

  35. Network features are components which are active participants in the utility network • Non-network features are parts of the system which are not directly involved in the utility network

  36. PDA DM for electricity networks

  37. ESRI DM for electricity networks • PDA DM based on ESRI model • ESRI model more general and comprehensive • Comprises the following components • Overhead, surface and underground structures • Devices • Circuit segments • Customer service

  38. ESRI DM for electricity networks • Structure is the abstract class that contains common characteristics, or attributes, for all electric structures involved in the distribution or transmission of electricity • Electric devices help ensure consistent service within the distribution network

  39. ESRI DM for electricity networks • Circuit segments contain classes and properties that describe the conductors that transmit and distribute electric current • Customer and service objects contain customer information and information about generators of alternate sources of electricity
