OpenFlows WaterGEMS helps engineers analyze, design, and operate water distribution systems. It includes genetic algorithm optimization modules for automated calibration, design and rehabilitation, and pump operations. It also includes modules for pipe renewal optimization, intelligent network simplification, and for the connection of a SCADA system to the water model. OpenFlows WaterGEMS is a superset of OpenFlowsWaterCAD, and can be run in Esri ArcGIS, AutoCAD, MicroStation, or as a stand-alone application.
