SewerGEMS is used by engineers to solve sewer system design and operation problems, especially those in systems with direct inflows such as combined sewer systems where hydrologic calculations are important and overflows are a key consideration. SewerGEMS® is a fully-dynamic, multi-platform, sanitary and combined sewer modeling solution, Engineers can analyze sanitary or combined conveyance sewer systems using built-in hydraulic and hydrology tools and a variety of wet-weather calibration methods. From urban sewer planning to overflow remediation analysis, to optimized Best Management Practices designs, SewerGEMS provides an easy-to-use environment for engineers to analyze, design, and operate sanitary and combined sewer systems. SewerGEMS is a dynamic wave model to simulate wastewater collection systems. It solves the full St. Venant equations and is especially suited for combined sewer systems where the hydrology of direct runoff into the collection system must be modeled. It is available in four compatible and interoperable interfaces: Stand-alone, Microstation, ArcGIS and AutoCAD. Regardless of the platform used, SewerGEMS users can collaborate maintaining a single set of modeling files for true interoperability across platforms. Interface and Graphical Editing Users of SewerGEMS enjoy the power and versatility afforded by working across CAD, GIS, and stand-alone platforms while accessing a single, shared, project data source. With SewerGEMS, utilities and consultants have built-in support for four interoperable platforms, all packaged together in a single product: Windows stand-alone for ease of use, accessibility, and performance, ArcGIS for GIS integration, thematic mapping, and publishing, MicroStation® for bridging geospatial planning and engineering design environments, and AutoCAD for integrated compatibility with CAD platform. Utilities and consultants can share a single dataset using different interfaces, and modeling teams can leverage the skills of engineers from different departments. Engineers can flatten learning curves by choosing the environment they already know and provide results that can be visualized on multiple platforms. * Stand-alone Windows interface included * ArcGIS-based interface (ArcMap) included * MicroStation-based interface included * AutoCAD-based interface included * Unlimited undo and redo * Element morphing, splitting, and reconnection * Automatic element labeling * Scaled, schematic, and hybrid environments * Element prototypes * Dynamic zooming * Multiple background file support * Image, CAD, and GIS background layer support
