Currently the file formats are quite different between WaterCAD/WaterGEMS and SewerCAD/SewerGEMS, so the model files cannot be directly opened or imported.
As a workaround, you can export the element information to a standard file format such as Shapefiles, then use Modelbuilder to import them into the other application. This can be a tedious process though, and some information (such as a pump definitions) will not be included in the Shapefile export.
