  1. Water Distribution System Network Calhoun County Rural Water By Steve Klaas MAY 17, 2013 GEOG 424: VECTOR BASED GIS DR SHUNFU HU, SIUE

  2. Creation of a Water Utility Network for CCRW • Geometric Network Created To Model Water Distribution System Network for Calhoun County Rural Water (CCRW) • Personal Geodatabase, feature dataset, feature classes, domains, subtypes, Geometric Network, and Utility Network Analyst all used to create network • Smart Utility Network allows parts to be disabled in order to determine effects on the rest of the system, such as a boil order for a broken water line Introduction

  3. Study Area Calhoun County, Illinois is the peninsula shown to the right of the arrow, between the Illinois and Mississippi Rivers Data Sets

  4. Only the central portion of Calhoun County was included for this project Data Sources Digital Orthophoto Mosaicfrom USDA NCRS Geospatial Portal Data Sets

  5. CCRW Geodatabase Contains all GIS Data Used in Project including Feature Classes within WaterDS Feature Dataset Methodology

  6. Geodatabase Domains Coded Values Used To Provide Legal Values for Each Field Type to Maintain Data Integrity Methodology

  7. WaterDS Feature Dataset Contains all Features Classes Used In Building Geometric Network: Water Lines, Customers, Valves, And Water Source Methodology

  8. Feature Classes Each Feature Class Was Given Categorical Subtypes with Default Values for Certain Fields Methodology

  9. Geometric Network Includes all features in WaterDS Feature Dataset. Geometric Network creation allowed further analysis to be performed through use of Utility Network Analyst Methodology

  10. Digitizing Features such as Customers, Water Lines, and Valves Digitized Using Digital Orthophotos as a Reference Methodology

  11. Water Tower Represented by Blue Water Tank Source Features Results

  12. Commercial Customer Subtype Represented as Squares Residential Customer Subtype Represented as Circles Sink Features Results

  13. Junction Features Three Sub Types of Valves 2 way, 3 way, 4 way Results

  14. Water Lines EdgeFeatures Six Inch Subtype Shown In Blue Four Inch Subtype Shown In Green One Inch Subtype Shown In Red Results

  15. Map Depicting Entire Network Conclusion

  16. Map Depicting “Smart” Network Using Flow Direction Arrows From Utility Network Analyst Conclusion

  17. “Smart” Network using Utility Network Analyst Broken Water Line Yellow Water Line is Disabled Red Asterisks Indicate No Flow Cyan Arrows Show Flow Direction Conclusion

  18. References • Data from USDA NCRS Geospatial Data Gateway • ArcGIS Desktop Help • Dr. ShunfuHu, Course Materials Thanks for your time
