Wausau Water Works
• Service to over 14,300 households
• 200 miles of water - sewer mains
• 1,380 fire hydrants
• 21 sewage lift stations
• Treats1.5 billion gallons of water annually

In the beginning….(there were paper maps)
Wausau Department of Public Works - GIS Division
Developing Digital Inventory(Water and Sanitary Sewer – Round One)
• Water and Sanitary Sewer utility mapping began 1997
• Used BaySys/GeoIT/KEMA software and data modeling expertise
• First attempt to determine necessary features in data model
• Features collected with GPS

Developing Digital Inventory(Storm Sewer Utility)
• Storm Sewer mapping started in 2001• Moved away from custom programming• Used standard ESRI software with
BaySys/GeoIT/KEMA modeling expertise• Out of the box ESRI, Microsoft Access, and
Visio (UML)• Features collected with GPS or imported from
existing AutoCAD or ESRI coverages
Wausau Department of Public Works - GIS Division
Arc Info 8.X – Windows 2000 – Standard ArcMap Editor

Engineering Drawing Archive
• Scanned and cataloged over 16,000 engineering plans, maps, documents

Developing Digital Inventory(Water and Sanitary Sewer – Round Two)
• 2002 - Convert UNIX applications to Windows• Bring all utility editing to one platform with
consistent attribute schemes• Good chance to remove unused attributes
and features• Features converted from ArcInfo Coverage
format to personal Geodatabases

Document Link Table
The feature-document relationships are many to many. So you can use the same record for several features.

Maintenance?
But, I’m not done mapping!
Wausau Department of Public Works - GIS Division
Maintain the Digital Inventory
• Have an update strategy in place before data conversion begins– What type of changes can occur?– How will GIS editor be notified of changes?– How often will digital inventory be updated?– How many edits are anticipated?– “Map” out the workflow to cover all possibilities

Maintain the Digital Inventory
• Water Utility:– tracking hydrant flushing, freeze-ups, breaks, leaks
• Sanitary sewer:– tracking: rodding, jetting, flushing,video surveys
• Storm Utility:– tracking cleaning activities

System Benefits – Future Plans
Wausau Department of Public Works - GIS Division
Benefits• Complete digital inventory with ability to query, display
and create maps at any scale• Accurate positional accuracy (not relative accuracy
anymore)• Ability to quickly share digital information with
developers, and engineers for site design• Automated map book process
– Blue-print machine removed, reduced staff time
• Increased available office space (no more map cases)• Faster response time to satisfy requests for
information
Wausau Department of Public Works - GIS Division
Future Plans• Move to multi-user environment/database
– “SDE in 2003”– To give water/sewer utility staff ability to edit
maintenance reports/data
• New GPS and base (Survey Grade RTK)• Develop an ArcIMS Utility Viewer• Storm Utility: Finish?!?!?!?
– East side completed. Working westward.– Slow process due to many new features never
mapped before (inlets and laterals)
• Field access?
