Thanks for raising this request on User Voice. For the drainage design requirements across the globe at a localised scale we have InfoDrainage, when looking to take a design which has been produced and to then understand the more holistic catchment wide impact of such a design, this is where the model can be imported into InfoWorks ICM for integration. It is probably worth exploring this in more detail in this instance to understand exactly what the end goal the client is after and at what scale the work is being completed if that would be possible.
