Introduction to Cobb County Water

• System Architecture– Feature Datasets

– Networks

– Editing/Versioning

Annually, the Water System Delivers approx. 24 Billion Gallons of water to 150,000+ customers in Unincorporated 

Cobb County.

Approx. 73 Million Gallons of wastewater is processed at one of the 4 WasteWater Treatment 

Facilities daily.

The Water System GIS team is responsible for maintaining a spatial database consisting of:

Silverlight Web Maps

• Arc10 Server 

• For use by County Maintenance personnel 

• Used by mobile workforce to identify assets and work in the field

• Very useful for identifying buried assets

Upgrade Project to Maximo Spatial

• ArcGIS 10 and Maximo 7.5• Used for Asset Management Water Systems

– Water, Sewer and Storm Water

• Maximo serves as a transactional and historical repository

• Maximo manages corrective and preventive maintenance work orders

• GIS serves as the As‐Built state of the Networks

Sharing of Data Between Systems

• The Spatial integration allows each system to maintain its data but share with the other.

• Data can be entered and exchanged from one system and viewed in the other. 

• No synchronization of data for maximum accuracy.

• Work processes can be streamlined using the tools provided.

• Flexibility for users to work in the system they are most comfortable with.

Business Risk Exposure (BRE)

• A County wide initiative to standardize a grading system to better enhance asset management.

• BRE will provide a scale to determine the ramifications of asset failure. 

• The trend data collected from the program will help prevent future asset failure.

• Prevents extremely costly repairs and negative environmental impact.

• Repairs can be proactive instead of reactive.

• Condition Assessment – the physical condition of an asset• Mitigation Factor – percentage value assigned to an asset 

which determines • Likelihood of Failure –Probability or expected frequency of 

a negative impact occurring.• Consequence of Failure – a negative impact on the 

established or required level of service

Expose Maximo Data to ArcGIS

• Expands available data sources related to assets in the network.

• Increasing the number of analysis options.

• Provides historical data for trend analysis.

• Allows for more intuitive symbology related to status and condition.

• Provides field personnel with visual condition of the current network.
