Bentley has been consistently the first to support new AutoCAD Releases. Bentley offers Water, Sewer and Storm water modeling software for AutoCAD.

No Integration through H2OMap Water.

.dxf files only.

ESRI Full integration with all current versions of ESRI.Bentley Systems has a technology partnership with ESRI. Bentley has a long standing relationship with ESRI and was the first water modeling company in the world to run directly inside ArcGIS.

Haestad Methods was an ESRI business partner and an ArcGIS reseller until 2004. Bentley Systems acquired Haestad Methods in 2004, and has supported 8.2, 8.3, 9.0, 9.1, 9.2 and 9.3 since then. Bentley will continue its commitment to interoperability and support of ESRI technology.

The following article is a white paper from ESRI's website about the GIS interoperability between Bentley and ESRI:http://www.esri.com/software/standards/bentley_esri_wp.pdf

An article at ESRI.com written by a leading consulting firm on GIS data exchange from ArcGIS to MWHSoft's calls their process "ugly" (see below):http://gis.esri.com/library/userconf/proc02/pap0835/p0835.htm

Although this article is about H2ONet, not H2OMap, the workflows are essentially the same.

Business Partner of ESRI.

MWHSoft claims its NAGCS membership of importance. NAGCS is a 6-member organization of which MWHSoft’s CEO is the director. DHI, a business partner and foundation partner award winner from ESRI and also a modeling software vendor is not a member of NAGCS. NAGCS standards are not officially recognized by ESRI.

GIS Integration Completely integrates with ArcGIS. Information stored in an .mdb file and can be utilized as part of the geodatabase.

Stores the data in flat dBaseIII tables (*.dbf files) or other file types. Use of shapefiles, Joins & Relates to integrate with ArcGIS.

Graphical User Interface WaterGEMS offers a customizable user interface to help maximize ease-of-use and create system wide color, size, query and report standardization. The graphical user interface allows you to call up a feature (background layers, scenarios, etc.) or dockable manager then position the dialog anywhere on the screen. The dialog can be docked or stacked on other features so that a simple tab allows you to switch between them.

Non-customizable user interface.

Element Symbology The ability to create multiple color coding and annotation layers for each element type. Allows multiple displays of color coding with different display settings that can easily be toggled on/off. Multiple Color coding and annotations setups are organized and saved into folders.Zoom limits can also be set that allow elements to visually be turned on/off at a set zoom resolution. Annotation can be independently scaled and rotated.In addition to ArcGIS based labeling, WaterGEMS also provides fully customizable display setup functionality. Users can choose to organize element labeling, color coding and sizing based on any attribute using powerful color scheme. This helps in setting standards for organizations.

Only one color coding or annotation layer available at a time. Old settings lost when new color coding or annotation created. No zoom resolution symbology.

(One of the many reasons, large utilities such as American Water, United Water and Aqua America have chosen to standardize on WaterGEMS across multiple states)

ArcGIS GeoTables GeoTables allow for a dynamic view of the GIS hosted information. The data maintained in the current scenario, the current timestep and the unit definition of the GeoTable is directly managed by ArcMap. Any columns added to an element GeoTable is automatically added to the ArcGIS Attribute Tables and is synchronized with the attribute tables. This means that columns, data and formats are shared between them.

Using GeoTables, you can: 1. Apply ArcMap symbology definitions to map elements

based on Bentley WaterGEMS & SewerGEMS v8 XM Edition data

2. Use the ArcMap Select By Attributes command to select map elements based on Bentley WaterGEMS & SewerGEMS v8 XM Edition data

3. Generate ArcMap reports and graphs that include Bentley WaterGEMS & SewerGEMS v8 XM Edition data

GeoTables simplify data entry, result analysis and editing inside of ArcGIS.

both input and output data. Multiple Project Interface All platforms support having multiple projects open

simultaneously. The method of moving from one open project to another varies per platform.

Only one model open at a time.

Data Sharing Share the same project file with AutoCAD, MicroStation, ArcGIS or Stand Alone modelers.

Model cannot be shared with other MWHSoft water distribution products. Data integration is one-way into the GIS platform.

All models must be imported and exported between interfaces. With associated loss of information.

Easy to Learn & Use Voted easiest water modeling software to use by Civil Engineering News Users survey in August 2007. American Water Works Association People’s Choice Award Winner in 20062006.

H2OMap Water’s ad-hoc programming tool sets have a steep learning curve. No context based help feature is available.

Ease of UseModel Creation Models can be laid out manually or imported. Two mouse

clicks allows you to easily split pipes, morph elements (i.e. change from one type to another), add bends and reconnect elements in any interface while maintaining property information.

Manual element layout does not support morphing, splitting of pipes or reconnecting elements from one node to another.

Model Builder ModelBuilder lets you use your existing data to construct a new model or update an existing model. ModelBuilder supports a wide variety of data formats, from simple databases (such as Access and DBase), CAD drawings, spreadsheets (such as Excel or Lotus), GIS data (such as shape files), to high end data stores (such as Oracle, and SQL

Shapefile, CAD, Excel, limited database import/export routines.

Server), and more. Using ModelBuilder, you map the tables and fields contained within your data source to element types and attributes in your WaterGEMS model. ModelBuilder also allows you to export your model data into the original source, or other files.

Demand Assignments LoadBuilder simplifies and expedites the process of assigning loading data to your model, using a variety of source data types:

You can assign loads from a variety of data sources to the model using nine different methods:

Billing Meter Aggregation—This loading method assigns all meters within a service polygon to the specified demand node for that service polygon.

Nearest Node—This loading method assigns customer meter demands to the closest demand junction.

Nearest Pipe—This loading method assigns customer meter demands to the closest pipe, then distributes demands using user-defined criteria.

Equal Flow Distribution—This loading method equally divides the total flow contained in a flow boundary polygon and assigns it to the nodes that fall within the flow boundary polygon.

Proportional Distribution by Area—This load method

Available as an Add-On.

An additional $3,000-$15,000 (Suite or Executive Package) plus maintenance fees ($1,000-$2,000).


9

proportionally distributes a lump-sum flow among a number of demand nodes based upon the ratio of total service area to the area of the node's corresponding service polygon.

Proportional Distribution by Population—This load method proportionally distributes a lump-sum demand among a number of demand nodes based upon the ratio of total population contained within the node's corresponding service polygon.

Unit Line—This load method divides the total demand in the system (or in a section of the system) into 2 parts: known demand (metered) and unknown demand (leakage and unmeasured user demand).

Projection by Land Use—This method allocates demand based upon the density per land use type of each service polygon.

Load Estimation by Population—This method allocates demand based upon user-defined relationships between demand per capita and population data.

WaterGEMS can also allow the user to use a subset (domain) of the total model elements and to only assign demands to a user specified subset.

Elevation Extraction TRex helps engineers build water models easily by extracting node elevation data from several types of digital elevation

No TIN Support.


10

models: DXF contours, Land XML, Model spot elevations, GIS shapefiles, DEM’s, DTM’s, TIN. WaterGEMS can extract elevation data from both vector and raster formats. This is a huge time savings in building the model.

Time-Series Data WaterGEMS’s Time Series Field Data dialog allows you to enter your observed field data and compare it to the calculated results from the model in graph format. This is especially useful in comparing time series data for model calibration. This feature can be used to display user-supplied time variant data values alongside calculated results in the graph display dialog. Model competency can sometimes be determined by a quick side by side visual comparison of calculated results with those observed in the field.

H2OMap Water does not support time-series data.

Model Skeletonization Skelebrator removes network complexity while maintaining connectivity, hydraulic equivalence and reallocating assigned demands to your specifications.

1. Choose between automated or manual skeletonization options, mark elements to be kept, and specify flexible tolerances and conditions to control every step of the skeletonization process.

2. Use one of our four different skeletonization types: data scrubbing, branch trimming, series pipe removal and parallel pipe removal.

Available as an Add-On.

An additional $3,000-$15,000 (Suite or Executive Package) plus maintenance fees.

No native VSP Pump Battery, No Hydropneumatic Tanks, No surge protection devices, No isolation valves, And hydrants are not managed

without specialty add-ons.

Variable Speed Pumps and Pump Batteries

WaterGEMS comes with an extremely powerful, exclusive (patented) variable speed pump feature. This feature was written to dynamically solve for the appropriate relative speed of the VSP pump(s) and can be used in any fashion with as many pumps in parallel as the user would like. All standard and logical controls can be used as with any other pump. This allows for true lead/lag pump modeling.

WaterGEMS can directly use a VSP pump with a pressure setting which will remove identifying storing and managing pump patterns. WaterGEMS also supports pumping patterns.

Changing a VSP pump attribute is a single click and because of inheritance it is instantaneously updated in all scenarios.

The speeds are calculated "external" to the main calculation that is done and then reinserted into their software. There are many other limitations of the H2OMap Water implementation – variable speed pumps cannot be placed in parallel, a target node cannot control more than one VSP. No lead/lag modeling.

H2OMap Water has a workaround to simulate VSPs by using a sub-routine i.e. first a pump speed pattern has to be developed for each pump and then applied to the pumps for running in a scenario.

If a VSP pattern needs to be changed in © 2010 Bentley Systems, Incorporated.

WaterGEMS holds a patent on VSP pump battery technology and can model flow based VSPs.

H2OMap Water, all of the subroutines need to be changed individually.

Since H2OMap Water uses a subroutine instead of an inbuilt VSP, the simulation time is significantly longer for larger systems.

H2OMap Water does not have VSP pump batteries. H2OMap Water is also unable to have different speeds when multiple VSP pumps are in parallel. In WaterGEMS, variable speed pumps (VSPs) are operated as one group and led by a single VSP, the so-called lead VSP, while the other VSPs at the same battery are referred as to as lag VSPs. A lag VSP turns on and operates at the same speed as the lead VSP when the lead VSP is not able to meet the target head and turns off when the lead VSP is able to deliver the target head or flow.

H2OMap Water has no VSP pump batteries and cannot model flow based VSPs.

Multi-Point Pumps WaterGEMS creates a computed curve based on the actual points which is very accurate.

H2OMap Water creates a linear interpolation for multiple point pump curves.


13

Tanks WaterGEMS offers multiple options for tank inflow. H2OMap Water does not have the option to assign a negative demand to tank to simulate inflow. It requires the user to put in an additional reservoir and flow control valve.

Hydraulic ModelingFire Flow Analysis Determine if the system can meet fire flow demands while

maintaining various pressure and velocity constraints. Fire flows can be computed for a single node, a group of selected nodes, or all nodes in the system. Run a fire flow at peak times during your Extended Period Simulation or on Steady State. Use the Fire Flow Results Browser to quickly jump to fire flow nodes and display the results of fire flow analysis of the system for the specified fire flow run.

WaterGEMS supports multiple simultaneous fire flow calculations.

H2OMap Water does not have a quick fire flow navigator. H2OMap Water also fails the regression test when the fire flow computations are rerun multiple times.

Prototypes WaterGEMS allows users to create prototypes. Prototypes allow you to enter default values for elements in your network. These values are used while laying out the network. Prototypes can reduce data entry requirements dramatically if a group of network elements share common

H2OMap Water does not support prototypes.

data.

Criticality WaterGEMS will automatically determine isolatable segments based on the location of your isolating valves. Choose the scenario and set the rules for use of valving and depending on the type of run, criticality analysis will report the flow shortfall, volume shortfall or pressure shortfall in the distribution system for each segment outage. Criticality will include the effects of reduced service pressure due to system outages.

WaterGEMS contains isolation Valves for accurate modeling of critical components of the system.

Available as Add-On.

An additional $3,000-$15,000 (Suite or Executive Package) plus maintenance ($1,000-$2,000).

NO Isolation valves in model.

Model Design Enter your hydraulic constraints, allowable pipe sizes, and associated unit costs and run automatic or manual designs using Darwin Designer. Our genetic algorithm methodology will evaluate hundreds of thousands of design and rehabilitation strategies based on any of these three objectives: minimize cost, maximize benefits, or multi-objective.



Flushing WaterGEMS flushing can perform conventional or uni-directional flushing analysis. Decide which hydrants you want to flush, and WaterGEMS will check that the maximum velocity achieved in any pipe during a flushing operation is met. Open/close isolation valves to perform uni-directional flushing analysis. UDF is included at no additional cost with WaterGEMS.

Not available for H2OMap Water.

Water Quality Calibration Water Quality Calibration is not utilized in 99% of models. An additional $3,000-$15,000 (Suite or © 2010 Bentley Systems, Incorporated.

This type of functionality is only used to adjust a single parameter (wall reaction rate) for disinfection analysis which is not normally done.

No user interest in functionality.

Executive Package) plus maintenance ($1,000-$2,000).

Pressure Dependent Demands

Pressure Dependent Demands (PDD) allows you to perform hydraulic simulation by treating the nodal demand as a variable of nodal pressure. Analyzing the effects of pressure on demand is very important in systems which do not provide 24 hour supply. Using PDD you can perform hydraulic simulation for:

Pressure dependent demand at a node or a set of nodes

Combination of PDD and volume based demand

Calculate the actual supplied demand at a PDD node and demand shortfall

Present the calculated PDD and the associated results in a table and graph.


Model Calibration and Leakage Detection

Available at no additional cost with WaterGEMS. Bring field data from SCADA or other data source to calibrate your model. Find optimal values for any combination of the model parameters such as pipe roughness, junction demands and link (pipes and valves) operational status, that best match the real-life situation in your hydraulic

system. Water Leakage Calibration is available only in WaterGEMS. This function is important to accurately predict the amount of leakage based on actual field data.

Energy Cost Analysis (Scheduler)

Available at no additional cost with WaterGEMS. Determine system operational costs of energy for the pumps and scenario. This can be utilized to schedule the best operating times for pumps to maximize efficiency and lower operating costs of the network.



Sensor Location Manager Currently not offered, but will eventually be able to link to the EPA-TEVA suite that has a tool for sensor location.

Based on PipelineNet method which is simple thematic mapping that they can done in native ArcGIS with no trouble. This method is not believed to be current state-of-the-practice and is not recommended.



Pressure Zone Manager Pressure Zones can be “freely” identified and managed using WaterGEMS’s network navigator, active topology and query management tools. Can currently use color coding to identify pressure zones based on hydraulic grade line. Network tracing tools enable user to identify open pressure zone boundaries.



Logical Controls Logical Control Manager is extremely rich and powerful. Difficult logical control user interface. Takes several more clicks to setup. Controls cannot

be reused or modified easily. Scenario Management Scenarios and Alternatives - data inheritance

Scenarios let you set up an unlimited number of "What If?" situations for your model, and then modify, compute, review and compare your system under those conditions. WaterGEMS offers unique data inheritance between alternatives so that inherited data is always up-to-date in all scenarios.

WaterGEMS has inheritance to unlimited number of levels because of the MDB file structure.

Alternatives can be quickly changed in scenario using a drop-down.

This is one of the many reasons for Power & Water Corporation from Darwin Australia decided leave H2oMAP and chose WaterGEMS and converted all their model files now in WaterGEMS from H2OMAP Water.

No alternative inheritance. For example if you have 5 different physical alternatives and need to correct a mistake in an elements data you will need to change each individual alternative. Failure to update all alternatives results in inconsistent scenarios and errors.

Need to copy alternatives manually.

H2OMap Water has no inheritance because of .dbf file structure. H2OMap Water creates duplicate files every time a change needs to be made. For example, if there’s a model with 100,000 pipes and one pipe needs to be changed, it will only take a single pipe change in WaterGEMS, but a total of 100,000 pipes need to be changed in H2OMap Water. If the diameter for 2,000 pipes need to be changed in 50 scenarios (typical for a large system), it will be 2,000 changes in WaterGEMS but with H2OMap Water it would take 100,000 changes.

Switching scenarios in H2OMap Water is slow because another .dbf file and dataset needs to be swapped in the memory.


18

H2OMap Water scenario names have an 8 character limit because of the .dbf file structure.

Water Hammer Analysis The transient elements for Bentley’s HAMMER and WaterGEMS are within the same tool bar.

HAMMER can work independently in addition to being able to work within AutoCAD, ArcGIS and MicroStation.

HAMMER uses the industry standard Method of Characteristics that computes at both nodes and pipes. This is critical to know the exact location, where a surge protection device needs to be placed.

There are no pre-requisites for HAMMER (i.e. it doesn’t require WaterGEMS).

MWHSoft’s InfoSurge and H2OMap Water use different toolbars requiring the user to import and export the model every time a transient analysis is required.

InfoSurge requires AutoCAD or ArcGIS license to work.

InfoSurge uses the Wave Plan method that performs analysis only at the nodes.

InfoSurge requires InfoWater or H2ONet, and cannot operate independent from them.

Problem Finding Tools – Network Navigator

Network navigator includes tools for reviewing and managing complex queries and for quickly finding problem areas in the model, for example: negative pressures, closed pipes, empty tanks, pumps operating out of range, etc), drawing queries and others. Drawing queries include finding orphaned nodes, duplicate links, dead end nodes, nodes in close proximity (possible duplicates) and pipe split candidates. All of these tools allow the user to validate the data as it’s created or during analysis. WaterGEMS’s network navigator also helps clean up GIS information saving

No dedicated water distribution network navigation help tools. Limited to queries using ArcGIS only.

hours of work and improving the data quality.

Named Views Quickly zoom to specific areas in your systems based on your own selections.


Reporting Tools WaterGEMS offers a wide range of reporting options and storage methods. The reporting tools available are color coding, size coding, annotation, 2D/3D animated profiles, FlexTables, graphs (line, bar, etc.) contours and project reports (inventory, summary, etc.).

All reporting tools can be opened simultaneously and multiple tables, graphs and profiles can be displayed at the same time.

Interface does not allow for multiple tables, graphs and profiles being open simultaneously.

Tabular Reports FlexTables lets you view input data and results for all elements of a specific type in a tabular format. You can use the pre-configured FlexTable or create customized FlexTables to compare data and create standardized reports.

FlexTables lets you view all elements in the project, all elements of a specific type, or any subset of elements. Additionally, to ease data input and present output data for specific elements, FlexTables can be:

Filtered Globally edited

Queried

Separate tables for Input and Output data, these cannot be mixed for easy analysis.

Only one table opens at a time.


20

Sorted

FlexTables can also be used to create results reports that you can print, save as a file (shapefile, ascii), or copied to the Windows clipboard for copying into word processing or spreadsheet software.

WaterGEMS provides for virtually unlimited customization including, order of columns, width, which columns are displayed, units, significant figures, display be selection sets, etc.

FlexTables also provide the ability to switch quickly and easily between units or one, multiple or all data fields.

Multiple tables can be open simultaneously. Post Calculation Processor Only Bentley’s WaterGEMS offers a post-calculation

processor for data. For example, if the average water age needs to be calculated for the past 10 days, this can be done directly inside WaterGEMS.

In H2OMap Water, data needs to be copied to Microsoft excel and averaged using excel’s functions.

SCADA Integration SCADAConnect allows the interaction with any SCADA system that supports open database connectivity (ODBC) interface or OLE DB interface. Citect's native application program interface (API) is used to allow access to data sampled by the Citect server. You can also connect to a database with many different types of data sources as needed.

H2OMap Water cannot bring SCADA information to its calibration module; it is limited to initial settings only. Bentley’s SCADAConnect can bring SCADA data to both calibration and initialization tables.

H2OMap Water does not have live support


21

for SCADA Data. It requires the user to develop a SCADA module that will write data to a particular file format and H2OMap Water will import that format. On the other hand, SCADAConnect can directly import SCADA data from SCADA database into WaterGEMS.

SCADAConnect is the only software that can do demand inversing and questionable data/missing data check for SCADA data.

H2OMap Water does not have true SCADA support; it creates file links and not a direct SCADA link with the SCADA system. The data will need to be brought in a particular file format for use in H2OMap Water. SCADAConnect is able to directly map signals to SCADA systems.
