                   TODAYS AGENDA

• SO YOU WANT TO BUILD A
  UTILITY GIS ?
• LET’S SEE WHAT WORKS (and
  what does not)
• WHAT ARE YOU GOING TO DO
  WITH THE UTILITY GIS ?


A   presentation
      WHAT IS THE GIS GOING
          TO BE USED FOR ?
• MAPPING
    – Looks Good; Annotation
• MODELING
    – Connectivity; Extended Attributes
• ASSET MANAGEMENT
    – Feature Identifier; Costs
• MAINTENANCE MANAGEMENT
    – Connectivity; Feature Identifier
A       presentation
                           MAPPING

•   Standard Maps for Community DPW
•   Title Blocks / Fonts / Symbols
•   Annotation / Text (Attributes)
•   Little or no Attributes in Database
•   Examples

Integration of GIS and
      Water Modeling


 Becky Cheadle, EIT
                   GIS / Water Model
                          Integration
• Water distribution model requires the
  following information:
  –   Pipe diameters
  –   Pipe ages
  –   Pipe layout and intersections
  –   Select ground elevations
  –   Pipe material
  –   Community zoning information
• Extra information:
  – Project identification number
Existing Auburn Hills GIS
Information in Existing GIS

   Without a complete GIS
     there is extra time to
      complete the model
     and…….extra time =
   extra $$$$$$$ for clients
        Hydrant Info from GIS
Fire hydrant testing is necessary to calibrate the
water model –
       with the use of the GIS we’re able to
       identify the exact location of the hydrants
       what size mains they are on and their ID
       number to be able to give the DPW a
       complete list to use during testing
GIS Import to H2ONet
        GIS Import to H2ONet
                       (con’t)
Map GIS attribute table columns to H2ONet table
                  descriptions
Resulting GIS Import to H2ONet
Data Available in H2ONet
      Table After Import
                                  Summary
• A complete GIS eases construction of a
  water model
  – Helpful to consider the necessary information
    for water models when initially building a GIS
• Reduces time needed to gather information
  to populate model database and therefore
  reduces cost!
• Extra information added to the water model
  can be exported to GIS to maintain a
  working system
  – Our Auburn Hills model is currently used by
    engineers to reference water mains for projects
