Using GIS to Manage Sewer Utility Maintenance

The Village of Mundelein, IL Public Works waste water division uses Geographic Information Systems (GIS) in three ways to track sewer maintenance progress.  The first method involves using a series of map atlases created using the Esri ArcGIS Desktop software. These atlases show sections of sewer that routinely need roots cleared or that need to be regularly degreased.  One advantage of this approach is that these atlases can be quickly changed as old issues are resolved and new issues develop.

The second method is using the Utility Editing tool that available in the village’s browser-based mapping application, MapOffice™ Web Access.  Through this tool, an employee selects lines and updates the dated flushed after each segment of pipe is flushed.  This information is then added to a map showing where recent backups have occurred.  This way the waste water division can monitor their progress to ensure they are fixing sewers that caused issues in the past.

The final way waste water monitors sewer conditions is by mapping comments collected during sewer televising effort directly in MapOffice™ Web Access.  This allows them to quickly see where clusters of sewers issues are located.  Then they can review to determine if additional areas need to be added to the root cutting and grease atlases.

Using GIS in a variety of ways allows the waste water division to monitor the condition of sewer pipes.  This information is used to ensure work crews know what type of maintenance is required.  It also allows them to track where sewers have been flushed and to plan for future sewer flushing schedules.
