How to rebuild map geodatabase in InfoWater Pro

Solution:

InfoWater Pro 2026.1 introduced a new way to rebuild the model's map geodatabase for troubleshooting purposes. If you are using a version with the new feature, all you need to do is run the Command Center -> Utilities -> Update Map from DB command and check the "Rebuild the map geodatabase" option in the popup window. Note that this method does not allow you to change the model to a different coordinate system, so if you need to do that you should continue with the old method described below.

If you are using a version older than 2026.1 or if you need to rebuild the model geodatabase into a different coordinate system, use the steps below:

This process will create a copy of the original model with a new map geodatabase (Map.gdb) file. All model data and settings will remain the same, however any GIS background layers or saved bookmarks in the ArcGIS file may need to be manually re-added.

1. Close the original model and if necessary save any changes.
2. Open ArcGIS Pro and create a New Project - Blank Map.
3. Specify the folder and project name for the rebuilt model.
4. Initialize InfoWater Pro and set the correct spatial reference for your model:
   1. Do not use Same As Active Map unless you are sure it is already set to the correct spatial reference. If you are unsure, follow the steps below to import the original model's spatial reference:
   2. Select Create New and hit the >> button.
   3. Press the globe icon and choose "Import Coordinate System" from the dropdown.
   4. In the popup window, browse to a GIS layer that you know is in the correct projection or import the original model's projection from the model's IWDB folder -> Map folder -> Map.gdb -> Network -> Junction layer.
5. Finish initializing InfoWater Pro and wait for the Contents pane to show all model layers. At this time the model is empty, but we will now copy the original model's data. 
6. Save and Close the rebuilt model.
7. Navigate to the original model's .IWDB folder and copy all of the .IWDB contents EXCEPT for the Map folder (Important: do NOT copy the Map folder as the point of this rebuild is to use a fresh map geodatabase).
8. Paste the copied data into the rebuilt model's .IWDB folder, choose "Replace all" when prompted.
9. Now reopen the rebuilt model and Initialize InfoWater Pro. We have copied the databases into this model but the map still needs to be recreated.
10. From the InfoWater Pro Command Center, expand the Utilities tree and run the "Update Map from DB" command. This will recreate the map from the databases, it may take a few minutes to complete.
11. If the model area does not center on screen, you may need to right-click on the Junction layer in the Contents pane and select "Zoom to Layer" to center the model area.
12. Click the Reset Display button the toolbar to apply your model's default appearance styles if needed.
13. Finally, it is good practice at this point to run a few database management tools to ensure the database and map are fully synchronized. Run the Reindex, Pack, and Clean tools found in the Command Center -> Utilities -> Database tree.
14. Save the model, this completes the rebuild process. You can now re-add any GIS layers, bookmarks, or other customizations to your ArcGIS Pro file.
