Top Reasons to Upgrade to SewerGEMS
- Retain all of SewerCAD's functionality
- Add SewerGEMS' dynamic engine
- The new SewerGEMS V8i now installs two individual programs:
- the new SewerGEMS Sanitary provides the same features as SewerCAD with the added ability to work within the ArcGIS platform. This means that SewerGEMS Sanitary allows engineers to use steady-state analysis with various standard peaking factors and extended-period simulations, as well as the powerful and easy-to-use automatic design features.
- SewerGEMS in which dynamic wave solvers account for storage effects within structures and quantify overflows should they occur. You can choose to use its implicit engine to solve the full St. Venant equations with stunning performance and numerical robustness, or the industry-standard EPA-SWMM engine.
- Model any type of collection system
Whether you have a separate wastewater, stormwater, or combined collection system, SewerGEMS gives you the ability to estimate and allocate sewer flows accurately and easily.
Leverage SewerGEMS' fully-dynamic engine to model overflows, looped sewer networks, wastewater pump stations, and even open channels and detention ponds.
- Gain the ArcGIS integration (in both SewerGEMS Sanitary and SewerGEMS)
The new SewerGEMS V8i now installs two individual programs; enjoy the power and versatility afforded by working across CAD, GIS, and stand-alone platforms while accessing a single, shared, project data source.
- ArcGIS for GIS integration, thematic mapping, and publishing;
- Windows stand-alone for ease of use, accessibility, and performance;
- MicroStation for bridging geospatial planning and engineering design environments;
- AutoCAD for convenient CAD layout and drafting.
- Built-in stormwater hydrology
Load models with wet weather runoff flows derived from precipitation, using SewerGEMS 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-SWM, or user-defined generic unit hydrographs.

Frequently Asked Questions
- If I already own SewerGEMS, how can I get SewerGEMS Sanitary?
If you have a SELECT subscription, just download the latest version of SewerGEMS. SewerGEMS Sanitary is included in the installation of SewerGEMS. It's like getting two products for the price of one!
- Do I need a SELECT subscription to apply the discount?
No. You may choose to not cover your SewerGEMS license with a SELECT subscription but we strongly recommend doing so. A SELECT subscription will not only give you unlimited upgrades and support, but also the capability of deploying your licenses on a network to share with unlimited users within your organization.
- What functionality will I lose if I upgrade from SewerCAD to SewerGEMS?
None. SewerGEMS installs two individual programs, including SewerGEMS Sanitary which provides the same features as SewerCAD with the added ability to work within the ArcGIS platform.
