Which versions of WaterGEMS, SewerGEMS and HAMMER support which versions of ArcGIS?
A matrix of supported versions of ArcMap and ArcGIS Pro for each version of WaterGEMS, SewerGEMS and HAMMER is available here:
For ArcGIS Pro, version compatibility may not follow the same pattern as ArcMap mentioned below. For example version 10.03.02.75 of WaterGEMS and 10.03.03.44 of SewerGEMS support version 2.6 of ArcGIS Pro, and we anticipate higher 2.x versions will also integrate, but version 2.5 and below will NOT.
A note on ArcGIS Pro version 2.7 - please contact Technical Support for a patch for WaterGEMS 10.03.02.75, or upgrade to a later version. Without the patch, you may notice problems with element layout, rotate and scale.
A note on ArcGIS Pro version 2.8 - as of 2021-Jun-22, currently this version is not supported with version 10.03.03.XX of WaterGEMS and SewerGEMS. You will need to downgrade to version 2.7 or upgrade to version 10.03.04.XX+ when available.

For ArcMap, the version shown in the matrix ("Platform Compatibility" link above) represents the latest compatible "minor" version (minor meaning the "x" in 10.x.y) which we have fully tested (certified). So for example if 10.8 is supported, that means 10.8.# (such as 10.8.1, 10.8.2, etc).
Earlier versions of ArcMap are also supported, in that the OpenFlows product will attempt to integrate with it and if a problem arises, Technical Support will assist. However it is generally recommended that you use the latest compatible ArcMap version shown in the above article.
