What is SewerGEMS?
Easy-to-use advanced engineering software, you can use SewerGEMS to analyze, design, and operate sanitary and combined sewer systems. Decrease decision risks by ensuring that the model uses the best available data, built-in hydraulic and hydrology capabilities, and a variety of wet-weather calibration methods. Create what-if scenarios to gain a better understanding of wastewater systems to make smarter decisions and improve your response times. SCADA integration provides you with reliable model results, improves capacity and limits sewer overflows, which ultimately enable you to comply with sewer regulations set by regulatory agencies.
- Work in multiple platforms
Flatten learning curves by choosing the environment that works best for you. With superior interoperability, SewerGEMS helps users get results that can be visualized on multiple platforms. Choose from Windows standalone 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 convenient CAD layout and drafting.
- Jumpstart the model building process
Leverage geospatial data, CAD drawings, SCADA data, databases, and spreadsheets to quickly kickstart modeling building processes. Easily connect with virtually any digital data format and synchronize database connections, geospatial links, and advanced model-building modules. And guarantee a hydraulically coherent model using the drawing and connectivity review capabilities.
- Allocate and estimate wastewater and stormwater loading
Assign sewer loads based on a variety of GIS-based sources such as customer water-use billing data, area-wide flow measurement, or polygons with known population or land use. Input and save an unlimited number of flow patterns, to accurately model flow changes over the course of a day. Load models with wet weather runoff flows derived from precipitation, using built-in rainfall distributions, or user-defined rainfall events. Runoff flows are modeled and calibrated using a choice of hydrograph methods, including RTK, SCS, Modified Rational, EPA-SWMM, or user-defined generic unit hydrographs. Users can also load the model based on property connections. Loading can be applied as user-defined hydrographs, pattern-based loads, and unit loads. Access and customize the comprehensive unit (dry weather) load engineering library with numerous typical unit loads based on population, area, count, and discharge.
- Easy model management with scenarios
Evaluate design, operational, sanitary loading, and network topology strategies for better decision-making support. Configure, evaluate, visualize, and compare an unlimited number of scenarios within a single file using the Scenario Management Center.
- Advanced analysis
Model the effect that low impact development controls have in retaining runoff before it enters the sewer system. Model hydrogen sulfide formation, with a view to decreasing the risk of pipe damage from H2S formation, preventing odor complaints, and improving workers’ safety.
- Multiple solvers
When analyzing, switch among multiple solvers, according to the type of system. To solve the Saint Venant equations, choose between SewerGEMS’ explicit EPA solver based on SWMM and the implicit dynamic wave engine. These two dynamic engines account for storage effects within structures and quantify overflows should they occur. The convex/gradually varied flow solver uses convex routing to determine gravity sewer flows and gradually varied flow (backwater analysis) to determine hydraulic properties once the flow is known. With the rational/gradually varied flow solver, peak flows in the storm sewer system are calculated using the rational method. Use this solver to analyze peak flow conditions, or to automatically design storm sewers.
What is the difference between OpenFlows SewerCAD and SewerGEMS?
SewerGEMS is a superset of SewerCAD. SewerCAD is currently not available for sale on Virtuosity.com but is available on Bentley.com/SewerCAD.
- SewerGEMS includes a standalone version plus the ability to integrate with three platforms MicroStation, AutoCAD, and ArcGIS. SewerGEMS’ full GIS, CAD, and SCADA interoperability enables the cost-effective sharing and flow of information between utilities’ design, engineering, GIS, and operation departments, and their consultants. SewerCAD only comes in a standalone version or AutoCAD.
- SewerCAD has a gradually varied flow engine for steady-state and extended period simulations for system design and rehabilitation that analyzes sanitary sewer networks under peak flow conditions with convex routing hydraulics. SewerGEMS uses a fully dynamic engine to help you accurately model looped networks, flow splits, overflows, and storage capacity.
Do I have to use SewerGEMS inside of ArcGIS?
No. SewerGEMS can be used as a standalone product. Additionally, enjoy the power and versatility of working across multiple applications with superior interoperability. Choose from Windows standalone, ArcGIS for GIS integration, MicroStation, and AutoCAD.
Do I have to purchase functional modules for SewerGEMS?
No. Unlike other platforms, SewerGEMS includes all calculation capabilities.
What is the difference between SewerGEMS and SWMM?
