Enterprise GIS and Mobile Mapping Solutions for Water Distribution Systems
Track: Water, Wastewater, and Stormwater
Author(s): Scott Harris, Ryan McKeon

The city of Baltimore has one of the largest and oldest water systems in the country, supporting more than 1.8 million customers along 3,400 miles of main. In a collaborative effort to rehabilitate and increase system operability, Wachs Utility Services, experts in water distribution systems, have designed and implemented an assessment management system through the integration of Esri's ArcPad and ArcSDE software, Trimble's GPS Analyst extension, and Tadpole-Cartesia's GoSync! Edit database synchronization tool.



Field crews, through the use of customized ArcPad forms, are collecting spatial and attribute information for approximately 65,000 valves and hydrants. The data is then incorporated into the ArcSDE/SQL database through a series of steps that include differential correction, disconnected editing, QA/QC procedures, and posting the new and updated data to the master database. The final step in the project workflow involves database synchronization between Wachs Utility Services and Baltimore Department of Public Works using GoSync! Edit.
