SewerGEMS

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.

Two engines for accuracy and compliance

Use SewerGEMS' implicit engine to solve the full St. Venant equations with stunning performance and numerical robustness, or the industry-standard EPA-SWMM engine for compliance with NPDES water quality regulations.

Built-in stormwater hydrology and calibration

Use and customize the built-in hydrology and engineering libraries with access to virtually any methodology to quickly load and estimate:

• Rainfall
• Infiltration
• Time of concentration
• Runoff hydrographs

Determining how much precipitation actually gets into the sewer is often difficult and time consuming. The RTK method, included in SewerGEMS, provides a simple and interactive technique for transferring precipitation into wet weather sewer loading.

Sanitary sewer load estimation

Use the LoadBuilder module to leverage water consumption, flow monitoring, land use, or census data in your GIS to automatically estimate and import sanitary loads for your SewerGEMS model.

Jumpstart your model with existing data

If you already have CAD drawings, GIS files, or existing SWMM, SewerCAD, or CivilStorm model files, you are only a few clicks away from having a SewerGEMS model of your network.

You can also build your model from scratch with easy-to-use layout tools working in a scaled environment, leveraging existing CAD drawings, shapefiles, and images as background references.

Find more time for engineering

Time-saving features help you streamline data entry and leave you more time for engineering and decision-making.

Use flexible tabular reports, maintain your own engineering attribute libraries for faster data input, create persistent multi-parameter queries, and manage engineering units on the fly.

Organize scenarios for better decision

The exclusive Scenario Control Center helps you organize an unlimited number of physical, design, hydrology, network topology, and operational scenarios to make faster and accurate decisions with a single SewerGEMS file.

Share your work with everyone

Use the included MicroStation integration features to generate smart PDFs to share your modeling results with anyone, or post your model drawings to the Web using MicroStation’s Google Earth Tools.

You can also leverage SewerGEMS' compatibility with the EPA-SWMM engine to effectively collaborate with colleagues and clients.

Understand results easily

Spot bottlenecks and potential surcharging with animated 3D graphs and profiles, use property-based color coding, element symbology and annotation to easily visualize your input and results, and create tabular reports, system-wide summaries, project inventories on the fly.
