Advanced tools for sanitary and combined sewer models
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. You can choose from these platforms:
- 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
- OpenRoads Designer, OpenSite Designer, and OpenRail Designer for a comprehensive 3D modeling solution
- AutoCAD for convenient CAD layout and drafting
1D/2D hydraulic analysis
User-friendly tools connect 1D network elements with 2D surface flows. Better understand surface flooding depth and velocity, flood hazard, and inundation times, and communicate this information to stakeholders with versatile mapping and reporting tools.
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.
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.
Perform 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.
