In the Beginning…
• Utility Management System began 1996.
• Utilized outside sources for design.
• Water utility mapping in March 1997.
• Sanitary mapping in August 1997.
• Personnel turnover in fall of 1997.
Water / Sewer Phase
Getting Started
• System Analysis • Know what your users need…
• A user is the best person to identify a clear set of requirements.
• In order to define a system, a users terms, definitions, and interpretations must be known.
Getting Started
• Meetings – to determine the users needs
• Models – to determine attributes and vocabulary

Data Entry /Collection
• Majority of features collected with GPS.
• Created copies of all valve cards, hydrant cards, miscellaneous info.
• Ran several check plots and compared to old mylar system sets.
• Mapping began in all areas of the city. Utilities were not completed in one area/section before moving onto the other.
System Map
Check Plots
GPS and Engineering Plans
• GPS along with good engineering plans will make your input much easier.
• Wausau had plans scanned by Master Graphics.
Discrepancies
…what is the hold up!?
• There is a demand for immediate and accurate utility mapping in many cities.
Maintenance Reports
• Updating your GIS
• Fire Flow Tests
• Maintenance – ie. New O-Rings place in Hydrant or a packed water valve

Stormwater System Management
What Path Do I Take?
Software Choices• AML based stormwater management?
• Geodatabase stormwater management?
•The choice for Geodatabase based on:
–The need to remove reliance of custom aml programming.
–Flexibility and functionality of ArcMap editing tools.
–The need for speed.
–The need for a long term solution.

• Geodatabase generated in Arc Catalog
• Existing Arc Info point coverages imported into database
Main line subsystem class
Document Link Table
The feature-document relationships are many to many. So you can use the same record for several features.
• Utilize GPS (Trimble Pathfinder Pro) with a data dictionary.
• Begin in a quarter section and stay with it until finished. Preferably a section near the city limits. These tend to be newer subdivisions and will have the necessary plans.
• Run check plots and let the people in the field scrub for errors.
Lessons Learned
Conclusion
• Both OS’s have been stable• Performance
-Arc Macro Language - Slow-Object oriented programming – Fast
• Next phase…– Convert water and sanitary to a geodatabase– Provide the data via ArcIms
