First, follow the steps above for creating a new WaterGEMS model. Then, use Modelbuilder to import the GIS. Modelbuilder is located under the "Tools" menu inside the WaterGEMS V8i menu. Select ArcGIS geometric network or ArcGIS Geodatabase features as the data source type, select your geodatabase features to import and follow the subsequent steps. How do you make elements inactive so they don't show up like you can do in the WaterGEMs standalone? https://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/13348.how-do-you-make-elements-inactive-so-they-don-t-show-up-like-you-can-do-in-the-watergems-standalone.aspx What is a Geotable? A geotable is similar to a flextable, but determines which fields/attributes are included in the WaterGEMS geodatabase when working inside the ArcGIS platform. ArcMap interacts directly with the personal geodatabase associated with the WaterGEMS model, not the WaterGEMS database (.wtg.mdb or .wtg.sqlite). The fields selected in the geotable are the fields linked between the WaterGEMS model database and the geodatabase. ArcMap can then apply symbology effects from the available geotable fields. What are some operations that I should NOT be performing in WaterGEMs for ArcMap? There are two operations that you should NOT perform when in WaterGEMS for ArcMap session: DO NOT add your own field to a WaterGEMS layer (Pipe, Tanks, Junction, etc...). DO NOT add files or manipulate anything in the WaterGEMS geodatabase file. Performing either of these operations could potentially corrupt the feature class in the WaterGEMS geodatabase or cause some kind or disconnect between the geodatabase and the WaterGEMS project files making the files unreadable. Can I add a field to a WaterGEMS layer without corrupting the feature class or geodatabase? Yes, you can add your own custom fields to a layer in your feature class but, it needs to be done through the WaterGEMS interface. What you'll need to do is click on the WaterGEMS toolbar and find the Tools menu. Off the Tools menu you should look for User Data Extensions and select it. This will open the user data extension manager where you can create a field for any one of your WaterGEMS elements. Details about how to use this feature can be found in the help documentation by searching the keywords "User Data Extension" or can be found here for "Creating Formula Based User Data Extensions". Which versions of WaterGEMS support which versions of ArcGIS? WaterGEMS version Compatible ArcGIS versions 08.11.04.58 10.2*, 10.1 08.11.04.57 10.1 SP1, 10.2** 08.11.04.50 10.0 SP5*, 10.1 08.11.03.19 9.3.1 SP2, 10* 08.11.02.31 9.3.1, 10* 08.11.01.32 9.3, 9.3.1 08.11.00.30 9.0, 9.1, 9.2, 9.3* 08.09.400.34 9.0, 9.1, 9.2* 08.09.165.12 8.3, 9.0, 9.1, 9.2* * Officially certified for this version only. **Only available if you have the latest patch set installed. I've integrated WaterGEMS with ArcGIS and I have the correct versions, but I don't see the WaterGEMS menu. Why? In ArcMap, right click in the gray area at the top-right corner. You should see several WaterGEMS entries available to add as toolbars. At a minimum, make sure "WaterGEMS layout toolbar" is selected. If I'm working in ArcMap without a WaterGEMS model open, am I still using a WaterGEMS license? For version 08.11.00.30 and below, you will still be using a WaterGEMS license. To prevent this from happening, you would need to first un-integrate WaterGEMS from Arcmap by using the "WaterGEMSXMUnreg.exe" file, located in the installation folder. Please be sure you have the latest cumulative patch set applied, before attempting this. In build 08.11.01.32 and later, license usage is only be recorded if you have an open WaterGEMS project in your ArcMap session. After working on a project in ArcGIS mode and saving an .mxd, why does the WaterGEMS model not appear when reopening the .mxd? The .mxd file is not linked to the WaterGEMs files so, after reopening the map, you must load the WaterGEMS project, under WaterGEMS View Project Manager. When working in ArcGIS mode, why are the tools in the WaterGEMS layout toolbar grayed out? First, you must open or create a WaterGEMS model in your current map, using the Bentley WaterGEMS Project menu. Also, you must be in editing mode to use the tools. Go to Editor Start Editing. How can I enable the flow arrows and active topology colors when working in ArcGIS mode? Go to Bentley WaterGEMS View Apply WaterGEMS renderer. Once the Renderer is applied, you can use the "show flow arrows" check box, under the same menu. How do I remove a color coding from a WaterGEMS layer? First right click on the layer you want to remove the color coding from in the table of contents and then select 'Properties' from the pop up menu to open the layer properties dialog. Now navigate to the Symbology tab and look on the left hand side of the dialog box (see image below). Here you should see that 'Quantites' - 'Graduated Colors' is selected. All you need to do now is click on 'Features' instead of 'Quantities' and then click Apply, OK. The color coding should be removed from the layer. In WaterGEMs for ArcMap I don't see a dashed line connecting the customer meters to the associated element like I do in WaterGEMS standalone. Why is this? https://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/17223.in-watergems-for-arcmap-i-do-not-see-a-dashed-line-connecting-the-customer-meters-to-the-associated-element-like-i-do-in-watergems-standalone-why-is-this.aspx When annotating or color coding in the ArcMap platform, why aren't all the WaterGEMS attributes available? The attributes available to color code and annotate on are based on the attributes included in the geotables. So, click the Bentley WaterGEMS V8 menu View Flextables. In the Flextables manager, open the "Geotable" corresponding to the element type in question. The fields shown in this table will be linked to the geodatabase and thus will be available to ArcMap for symbology. Use the yellow 'edit' button to add or remove attributes. What is the best procedure to take to when creating a shapefile or feature class to help ensure that when I bring a model in using modelbuilder I won't run into problems with pipes or junctions not being connected correctly? The best way to help ensure that everything comes in correctly using modelbuilder starts when the file that you are trying to bring in is created in ArcMap. When creating the file you should make sure to turn on all your snapping options so the elements are actually connected in ArcMap and there aren't gaps between the elements. Another thing that you want to do is make sure that you are laying out the elements correctly according to WaterGEMS rules. This means that every pipe needs to have some type of node element attached at either end. Node elements include junctions, tanks, valves, reservoirs, and pumps. If possible it's also advised to create a new pipe between each two nodes elements. This means that instead of laying out all your pipes first when creating your shapefile (feature class) you would create things in the following manner: Create a node element Create the line element representing the pipe Create the end node element for the line Repeat steps 1-3 until finished. What is the difference between using the "WaterGEMS for ArcMap" shortcut versus opening ArcMap regularly? When opening the "WaterGEMS for ArcMap" shortcut, the main WaterGEMS menu toolbar will always be visible. Besides this, both methods are the same. WaterGEMS will be registered in ArcMap for both cases and license utilization will only occur when a WaterGEMS project is loaded.

Applies To Product(s): Bentley PondPack Version(s): 08.11.xx.xx Environment: N/A Area: Calculations Subarea: Original Author: Scott Kampa, Bentley Technical Support Group Error or Warning Message When computing a model, the following user notification is generated: "One or more level pool routing ponds is connected to an ICPR (Time vs. Elev) or ICPR (Elev vs. Flow) outfall node. If using level pool routing on pond routing link, the downstream outfall node must be set to a standard outfall." How to Avoid The outfall Boundary Condition Types "Time-Elevation Curve" and "Elevation-Flow Curve" are treated as interconnected pond (ICPM) type conditions. For that reason, the composite outlet structure that is attached to the outfall must be set to be use ICPM Routing. To do this, open the Composite Outlet Structure manager (Components Composite Outlet Structures). Highlight the composite outlet structure and find the property "Tailwater Type". Set this to "Interconnected Ponds." The other option would be to use a different boundary condition type for the outfall.

Wiki Page: Why is there a place to enter the elevation for an irregular weir on the structure and in the cross section table?
Applies To Product(s): Bentley SewerGEMS, Bentley CivilStorm, Bentley PondPack Version(s): 08.11.XX.XX Environment: N\A Area: Layout and Data Input Subarea: N\A Original Author: Mark Pachlhofer, Bentley Technical Support Group Problem Description Why is there a place to enter the elevation for an irregular weir on the structure and in the cross section table? Resolution The elevation property on the structure itself is the invert elevation of the weir. The elevations in the cross section table are all based upon this invert elevation property or in other words, they are added to the invert elevation. For example, if you weir has an invert elevation of 5 ft. and the cross section elevations are at 10 ft., 15 ft., and 20 ft. and you put 5 ft. in as the invert elevation then the cross section information would be 5 ft., 10 ft. , and 15 ft. Some people find it easier to just leave the invert elevation property at 0 and simply enter the regular cross section elevations.

Wiki Page: ModelBuilder error: Microsoft Access Database Engine 2010 64-bit is required to access this data source
Applies To Product(s): Bentley WaterGEMS, Bentley WaterCAD, Bentley HAMMER, Bentley StormCAD, Bentley CivilStorm, Bentley SewerGEMS, Bentley SewerCAD Version(s): 08.11.04.XX+ Environment: Windows 7 64 bit Area: Layout and Data Input Subarea: Original Author: Scott Kampa, Bentley Technical Support Group Problem Description When trying to import an Excel spreadsheet or Access database file into Modelbuilder, the following message dialog is generated: Microsoft Access Database Engine 2010 64-bit is required to access this data source. Note that this applies to all of the products listed above. Reason ModelBuilder can use a number of different file types to create a model, including Excel spreadsheets and Access database files. When one is using the 64-bit version of the Bentley product, and they try to import an Excel spreadsheet or Access database created with the 32-bit version of Office, the referenced message will be generated. Essentially, because the 64-bit Microsoft Access Database engine was not detected, the file will not be imported. The Access Database Engine is required to use these data source types. There is a Help button on the message that will give some additional details, including two potential workarounds. Steps to Resolve The first workaround listed is to try to install the 64-bit version of the Microsoft Access Database engine. This can be foundon Microsoft's website. This is a suitable workaround if there is no instance of Office installed. However, if the 32-bit version of Office is installed, you will not be able to install the 64-bit version of the Microsoft Access Database engine, since it will cause a conflict with the version of the engine that is already installed. In these cases, the second workaround can by used. If the user browses to the installation folder (by default that would be C:\Program Files (x86)\Bentley\ ProductName and double-clicks on the .EXE file corresponding to the product (such as WaterGEMS.EXE, SewerGEMS.EXE, HAMMER.EXE, etc) the 32-bit version version of the product will be launched. The user can then use ModelBuilder to build a model using the Excel spreadsheet or Access database created in the 32-bit version of Microsoft Office. This only needs to be done once; you can import your data through Modelbuilder in the 32-bit version, save the model, then open the 64-bit version using your regular desktop shortcut. Note: if you're having trouble opening the .EXE file, ensure that you do not have file extensions hidden in Windows explorer. Otherwise, you might be opening for example SewerGEMS.exe.config, even though it looks like "SewerGEMS.exe", since the .config was hidden. You can access this option in the Windows 7 and Windows 8 Explorer, in the upper-left side under Organize Folder and Search Options View Hide Extensions for Known File Types. If you'd like to have the 32 bit version of the Haestad application on your desktop for quick access you can also right click on the .EXE file in the program files folder and use the 'Send To' Desktop option to create a shortcut on your desktop. Generally speaking, the 32-bit version should work without a problem in most situations. For very large models that may consume a large amount of system memory, the 64-bit version will help ensure that you do not run out of memory (as 32-bit applications can only access a limited quantity of memory). There are also cases where we have seen a the 2007 Microsoft Access database engine be removed from the computer by someone for some reason. This can also cause a problem because removal of the 2007 version of the Microsoft Access database engine can break the 2010 version. What you can do in order to fix this is download the 2007 Access database engine from the Microsoft website and install it manually. You also have the option to uninstall WaterCAD and reinstall it if that is easier for you.

Forum Post: RE: Help With setting up a VSP or VFD with 4 pumps.
If you'd like to upload your model files for us to have a look you can do so using the options outlined below: There are two options for sharing your model files on BE Communities. If you would like the files to be visible to other members, compress the files into a zip file and upload them as an attachment using the ‘Advanced Reply editor’ before posting. If your data is confidential, you can follow the instructions in the link below to send it to us via Bentley Sharefile. Files uploaded to Sharefile can only be viewed by Bentley. communities.bentley.com/.../bentleysecurefilesupload.aspx Another thing that might be useful to know is if you have the latest version of the software. The version number can be found by going to HELP About SewerGEMS inside your program and locating the number in the lower left hand corner and may be in brackets. It should start like this 08.11.XX.XX where X are some numbers. The latest version is 08.11.04.58 and if you don't have that the first thing you might want to try before sending your model is upgrading to that version. You can find directions for downloading the latest version of the software from this link: communities.bentley.com/.../8175.how-do-i-download-watergems-watercad-hammer-sewergems-sewercad-civilstorm-stormcad-pondpack-flowmaster-culvertmaster.aspx Another thing that you might want to try is going into the calculation options for the scenario that you have and changing the LPI coefficient to 5. If you still have the same result after doing that try changing it to 12 and see if that helps. Regards, Mark

Forum Post: RE: Vapor pressure
Vapor pressure is only a function of temperature. The actual absolute pressure depends on the elevation. Tables of vapor pressure of water is available in most chemistry, physics and fluids text books. Vapor pressure at 45C is roughly 10 Pa (Tchobanaglous and Schroeder). You should contact the PRV manufacturer for allowable downsurge pressures. Another source would be the PVC pipe organization, uni-bell. http://www.uni-bell.org/

Forum Post: RE: Pump Selecting
The process mentioned on page 344 of chapter 8.6 can't be used with a closed system. Here are the options I see: 1) Insert a pump with an estimated pump curve (it doesn't matter since the system head curve is independent), then run the system head curve tool with downstream demands set as PDD. 2) Look at the sum of the downstream demands for typical conditions, then select a pump curve whose best efficiency point is near that flow, with a corresponding head that would provide adequate system pressures. 3) Consider a variable speed pump . There is some additional advice on this on page 312-313 of the AWDM book.

Steps to Resolve Option 1 Make sure your WaterGEMS (or SewerGEMS model is attached and contains inactive elements. Go to the "Bentley WaterGEMS" menu (or "Bentley SewerGEMS" if using SewerGEMS), choose View and make sure "Apply WaterGEMS/SewerGEMS Renderer" is checked. The inactive elements should be colored gray (if using the default inactive element color). If you would like to turn them off completely, go to "Bentley WaterGEMS" (or "Bentley SewerGEMS" if using SewerGEMS) Tools Options and uncheck "Display inactive topology". Press the zoom full extents button to refresh the drawing. The inactive elements should disappear.

Wiki Page: Hydraulic grade line is below the invert of a conduit or channel
Applies To Product(s): Bentley CivilStorm, Bentley SewerGEMS Version(s): 08.11.xx.xx Environment: N\A Area: Calculations Subarea: N\A Original Author: Scott Kampa, Bentley Technical Support Group Problem Description In viewing a profile, the hydraulic grade line is below the invert elevation for a conduit or channel. How can this be resolved? Steps to Resolve The likely cause of the issue is that the start and stop nodes for the link is reversed. If you are using the invert elevation of the nodes to define the inverts of the channel or conduit, this can cause the program to think that the lower invert elevation is at the upstream end of the conduit or channel, instead of the downstream end, which is typical. To fix this, go the link where the issue is occurring. Confirm if the start and stop nodes are correct. If they are not, find the property field "Node Reversal" and click the '...' box in this cell. That will reverse the start and stop nodes. After recomputing the model, the results should improve.

Wiki Page: Zero overflow at manhole despite HGL above rim (Solution 500000059548)
Applies To Product(s): Bentley SewerGEMS Version(s): 08.09.025.00 and 08.09.26.17 Environment: N\A Area: Calculations Subarea: N\A Original Author: Jesse Dringoli, Bentley Technical Support Group Problem In SewerGEMS or Civilstorm, why do I see 0 (zero) overflow for a manhole during a timestep in which the HGL at that manhole is above the rim? Problem Number 32696 Version: 08.09.025.00 and 08.09.26.17 Solution First, make sure you do not have a bolted cover. If you do not, then this is likely caused by tailwater. In version 08.11.00.08 and below, SewerGEMS and CivilStorm cannot calculate overflow from backed up water due to tailwater. It can only calculate overflow from upstream water. If you have version 08.11.01.21 of SewerGEMS, you can overcome this issue by increasing the LPI coefficient in the advanced calculation options. For example, try a value of 12.0. This allows the calculation engine to have more dynamic effects and account for the overflow from backwater. Note that this will only work for circular conduits. See Also

Forum Post: Inserting PRV into WaterCAd V8i
I added a PRV onto a pipe and when I run my Scenarios, I get negative pressures (on the factor of 10 million). The valve is connected to the system, the velocity of the flow is pretty low so I'm pretty sure that's not an issue, I've also checked my elevations and demands, but those all seem to be fine. I did not add any losses to the system except at the valve. I'm wondering if it's an issue in the PRV itself? I have a diameter of 18" on the valve as well as an initial pressure setting of 88 psi. I used a Butterfly Valve type and kept the defaults on everything else. I notice that when I change my diameters, my pressures change, but it still remains in the negative millions. I also added a minor loss coefficient to the valve, but again, it only helped slightly. Any possible ideas or should I provide more information?
