About InfoWorks ICM
InfoWorks ICM (Integrated Catchment Modelling), now an Autodesk product from the Innovyze lineage, is the enterprise standard for large urban drainage and sewer models: full hydrodynamic network simulation coupled natively to 2D overland meshes, real-time control, water quality, and multi-user database-backed model management that large utilities rely on.
Where a city-scale combined-sewer model with dozens of contributing modellers is the job, ICM's model-management layer is the differentiator no open stack currently matches. It is priced accordingly; SWMM-based stacks remain the escape hatch for smaller scopes.
