Urban Sanitary and Combined Sewer Modeling and Management


What's new in SewerGEMS?

Bentley offers the first and only urban sewer modeling solution with AutoCAD support and ArcGIS, MicroStation, and stand-alone interoperability.

SewerGEMS V8i joins WaterGEMS and HAMMER as the only water resources modeling software to run within AutoCAD, ArcGIS, and MicroStation, or as a stand-alone application, underscoring Bentley’s commitment to interoperability.

“As an engineer, I always want to leave as many doors open as possible,” said Jonathan Bedsole, PE, Staff Engineer at Athens Utilities Water Services in Alabama. “When I began looking for a wastewater model, I wanted to be able to integrate a model into AutoCAD and ArcGIS. SewerGEMS met that need as well as adding flexibility with a stand-alone platform.”


Key new features in SewerGEMS V8i (SELECTseries 4):


SewerGEMS V8i (SELECTseries 4) is now available. Click here to learn how to get this new version.

INTEROPERABILITY

Updated support for MicroStation: You can run SewerGEMS from within the latest releases of MicroStation V8i (SELECTseries 3). A MicroStation license is required – if you don't have a MicroStation license, you can choose to run SewerGEMS in stand-alone mode.

Updated support for ArcGIS: You can run SewerGEMS from within ArcGIS 10.2 SP1. An ArcGIS license is required – if you don't have an ArcGIS license, you can choose to run SewerGEMS in stand-alone mode.

Updated support for AutoCAD: You can run SewerGEMS from within AutoCAD 2015 and 2014. An AutoCAD license is required – if you don't have an AutoCAD license, you can choose to run SewerGEMS in stand-alone mode.

Direct import of MX Drainage files: The import of MX Drainage files in SewerGEMS has been improved, reducing the steps necessary to leverage MX Drainage data.

Bentley Map Mobile i-model publishing: This tool publishes a SewerGEMS model, including results, for use in Bentley Map Mobile, a free app that works on Android, iPad, and iPad mini tablets.

MODEL BUILDING AND MANAGEMENT

SCADAConnect: Users can now set up live data connections to SCADA systems, so that SCADA data can be used for calibration purposes and real-time simulations.

SCADA element: This element represents a real-world SCADA signal that is associated with a hydraulic element in the model. It displays both real-time and historical SCADA data as well as the difference between SCADA and model results.

Elevation data assignment: SewerGEMS can automatically assign elevation data to node elements, including manholes, using digital terrain models. The node elevation can be updated automatically when the element is moved.

Downstream trace: SewerGEMS enables the convenient trace and display of the surface water flow direction across any terrain.

Redesigned conduit catalog: Conduits with the same section shape and materials are now grouped together in the conduit catalog, making it easier to view and edit them.

HYDRAULICS

H2S modeling: SewerGEMS can now model hydrogen sulfide formation in pipes, nodes, and wet wells.

Headwall and endwall elements: SewerGEMS now supports culvert headwalls and endwalls, which can connect to open channels or closed conduits.

Inlet-only hydraulic calculations: Users can now place inlets, check gutter and inlet carryover flows, and adjust the inlet positions as necessary, before designing the pipe network.

Storage chambers as pond type: SewerGEMS can now model underground storage chamber systems.

Improvements to automated design: The automated design calculations for sanitary and storm sewers include a number of enhancements, such as: pipe wall thickness can be included when computing cover; drop structures can be used to minimize cover (previously drop structures only prevented a pipe from exceeding the maximum allowable slope); and a minimum drop depth can be specified for drop structures.

HYDROLOGY

PondMaker: SewerGEMS' PondMaker is an easy step-by-step detention pond and outlet structure design tool.

New hydrograph methods: Users can now choose to utilize the ILSAX or time-area hydrograph methods to compute runoff.

New loss methods: SewerGEMS now allows users to compute infiltration losses using ‘initial loss and constant fraction’ or ‘initial loss and constant rate’ methods.

New time of concentration methods: SewerGEMS now supports the following additional time of concentration calculations: Kinematic Wave equation, Friend’s equation and Bransby-Williams equation.
