The fundamentals of water supply modeling are well established, but engineers, planners and operators are continually expanding the range of activities they expect from their modeling solutions. Innovyze water supply modeling products excel, not only with fast and robust hydraulic and water quality simulation capabilities, but with superior easy-to-use interfaces and a wide range of features and functionality. They enable users to deliver better, higher-quality projects faster. InfoWorks WS Pro operates as a standalone or workgroup management platform compatible with multiple GIS solutions. InfoWater works as an integrated part of the Esri ArcGIS environment. InfoWater SA provides stand-alone engineering-GIS modeling, and H2ONET allows the quick and convenient building of water distribution CAD models as an AutoCAD extension. In addition, InfoWater, InfoWater SA and H2ONET are based on an improved, much faster version of EPANET.
