If you want to start a new project with combined sanitary & storm modeling, then we assume that you are having Bentley SewerGEMS, is it right? You can find good examples in the installation folder- C:\Program Files (x86)\Bentley\SewerGEMS8\Samples. Please go through the Quick Start lessons, which contains the example of combine storm-sewer modeling. Also we have online training on Learn Server learn.bentley.com/.../Public

First, you should have a talk with the people in you GIS department about inserting nodes at the right places. Then, run the Network Navigator query Network Review > Pipe Split Candidates. Then right click and pick Merge Nodes in Close Proximity. A dialog will pop up asking you which nodes you want to merge.

Forum Post: RE: Slipt pipe in watergems
To split the overlapping pipe and connect the node, either right click the node and choose Split, or take a look at the Batch Pipe Split tool if you have a lot of these. If you search in the Hydraulics and Hydrology Support Solution area, you'll come across this relevant article: communities.bentley.com/.../8678

Forum Post: RE: Slipt pipe in watergems
Thanks Dr. Tom and Jesse I know that Batch Pipe Split tool can do, but just with exsiting noughbouring nodes found withthin specificed tolerance distance. My problem, there aren’t orphan nodes, there are disconected between distributed pipes with tranmission pipes. The way “right click the node and choose Split” is right but I can’t use Batch Pipe Split Tool for that.

Forum Post: RE: 2 networks in 1 project
Hello, First, what program are you using? That can be important depending on how the elements are attached. Based on the screenshot, you have two separate gravity subnetworks. One is going from MH-8 to O-2, the other is going from MH-1/MH-5 to O-1. The conduits CO-8 and CO-7 are crossing pipes but not attached. This is allowable in any of the programs or solvers you may be using. Basically, for each gravity subnetwork, you need to have an outfall as well. That is appears to be the case in your setup, so it should work fine. If that doesn't help, I will need some additional details on what you are trying to model. Regards, Scott

Sewercad The attached picture for illustration only. Not that I intend to work in. When I want design a large separate networks.. 1. How can I lable each network elements separately? 2. How do I run a design or analysis of the network without affecting other network? 3. can the program shows the intersections at both networks and avoided? 4. How can I specifying design constraints for each network is. So as not to affect other network?

Forum Post: RE: 2 networks in 1 project
1. When you build the networks, you can use Tools > Options > Labeling to start one network at say CO-1 and the other at PIPE-1. 2. Just turn on the Topology for the network you want. If you insist on putting everything in one Project File, I would set up three active topology alternatives: 1. All, 2. Network A and 3. Network B. 3. ?? 4. Set up different Design alternatives. I would rely heavily on Selection Sets to work on one set or elements or another. Good luck.

Wiki Page: Modeling split flows in SewerCAD , StormCAD , or SewerGEMS/CivilStorm using the GVF convex or GVF rational solvers
Applies To Product(s): Bentley SewerGEMS, Bentley SewerCAD, Bentley StormCAD Version(s): 08.11.XX.XX Environment: N/A Area: Layout and Data Input Subarea: Original Author: Terry Foster, Bentley Technical Support Group Background I would like to model a split flow in Bentey SewerCAD, Bentey StormCAD, Bentley SewerGEMS, or Bentley CivilStorm. If you are using Bentley SewerGEMS or Bentley CivilStorm the steps below to enter a diversion rating table only apply to certain numerical solver. In SewerGEMS the directions will apply to the GVF rational solver (StormCAD) and the GVF Convex solver (SewerCAD). The directions will apply for the CivilStorm GVF rational solver (StormCAD). **Please note that SewerGEMS and CivilStorm also come with the implicit and the SWMM solvers, which are both fully dynamic solvers, that do not require you to enter a flow split as it's taken care of automatically. You can find more information as to which solver is best to use for your model in this wiki ** Steps to Accomplish First, you will need to identify one of the conduits coming out a manhole or catch basin as a diversion link. If you double-click the conduit to view the properties you will find a property field titled "Is Diversion Link?". Set this to "True" and new property fields will be available to enable the addition of a diversion rating curve. To set of the diversion rating curve, click the ellipsis (...) button in the field "Diversion rating curve". This will open a new dialog where you can enter a table for incoming flow versus diverted flow. In other words, for a given upstream incoming flow you are defining how much of that incoming flow will travel down the pipe marked as the diversion. The remaining flow will go down the other downstream pipe. What you are doing here is manually defining how the flow split functions. For example, you could assume a 50/50 split. You can also have no diverted flow for a part of the curve and only allow diverted flow once it reaches a certain flow amount. In the above example, when you have an incoming flow of 10 cfs none of it will be going down the diversion pipe; all of the 10cfs will be going down the other pipe. This might happen if the diversion pipe has a higher invert and the water surface has not reached that elevation yet. Once you have this set up you can then compute the model. The flow should split based on the diversion rating curve that you entered. Sometimes you may not always know what this diversion rating curve is. If you have access to Bentley SewerGEMS or Bentley CivilStorm, you could use these to help. SewerGEMS and CivilStorm use the Dynamic Wave solver (Implicit solver or SWMM solver) and can model split flows in a storm or sanitary system automatically. As a result, you can use these programs to help created the diversion rating curve, which you can then use in StormCAD or SewerCAD. To check which solver you have selected go to View > Calculation Options and double click the active calculation option with the red check mark on it. Check to see what the active numerical solver is set to. To do this, set up a small model with the manhole in question and incoming/outgoing pipes, with a load on the upstream node covering a range of expected flows. Compute the model and look at the flow through one of the conduits, then build your diversion rating SewerCAD or StormCAD based on these results. Using CivilStorm as an example, below is a simplified model: At manhole "X", an Inflow (Wet) Collection has been set up to represent flow into the system. You can see the steps by the graph for the different times and flows. When the flow goes through Manhole "Y" it is split between Pipe "B" and pipe "C". How much flow goes into each pipe will depend on the diameter of the pipe and the invert elevations. As noted above CivilStorm and SewerGEMS implicit and explicit solvers can calculate the split flow automatically. After computing, the results are graphed below. You will see the flow for pipes A, B, and C. You can enter the data from points on the graph into the diversion rating curve in StormCAD or SewerCAD, or you can copy/paste from the data tab. If you are going to copy/paste, you would copy the data from the column of the upstream pipe to Upstream Flow (cfs). You will copy the data from the pipe that will be the diversion pipe to Diverted Flow (cfs). In summary, if you have a model with several complicated diversions you may want to consider using CivilStorm (Implicit solver) or SewerGEMS (Implicit solver), as they are best suited for more complicated flow split situations.

Could you clarify what you mean by "at the same level"? Are you interested in clash detection (making sure two crossing pipes from the different utility type don't run hit each other, physically?)

Wiki Page: Using Imperial and Metric Hydro International Vortex Valves
Applies To Product(s): Bentley SewerGEMS, Bentley CivilStorm, Bentley PondPack Version(s): Multiple Environment: N/A Area: Modeling Subarea: Original Author: Jesse Dringoli, Bentley Technical Support Group Introduction The Vortex Valve pond outlet control structure has been available in Bentley PondPack as of version 08.11.01.51 as well as Bentley SewerGEMS as of version 08.11.02.46 and Bentley Civilstorm as of version 08.11.02.62. Hydro International vortex valves previously included in these products covered only Imperial units. This article explains how to obtain updated Engineering Library data for Hydro International Vortex valves, covering both Imperial and Metric units, with some fixes for SXH and CX models (10.5"-12" sizes.) This update is from August 2014 and is compatible with Pondpack, SewerGEMS or CivilStorm (minimum version mentioned in previous paragraph.) If you have a version of these products released after August 2014, it may already include this update. Models included: SH, sizes 3-12 inches (76-305 mm) CH, sizes 3-12 inches (76-305 mm) SXH, sizes 3-12 inches (76-305 mm) CX, sizes 3-12 inches (76-305 mm) Downloading and Installing To download a copy of this updated Hydro International vortex valve library, click the below link: Download HydroInternational.xml Before downloading this file, note the two options below: Option A - If you already have a version of PondPack, SewerGEMS or CivilStorm that includes the Hydro International vortex valve library, you can simply overwrite the previous copy of the file. To do this: 1) Open the software, go to Components > Engineering Libraries, expand Vortex Valve Library, expand HydroInternational.xml, expand the folders and click one of the individual vortex valves. 2) On the right side, you will see a path shown next to "Engineering Library Source". Make note of this folder path and then close the software. For example the default path to this file for PondPack on a Windows 7 computer is C:\ProgramData\Bentley\PondPack\8\Libraries\ 3) Now, when saving the above file, choose to save to this location and choose yes when asked if you'd like to overwrite the existing file. 4) Re-open the software and the new sizes will be available in the Vortex Valve Library. Option B - If you have one of the compatible versions of PondPack, SewerGEMS or CivilStorm but either do not see an existing Hydro International vortex valve library included, or if you have a problem with it, follow these steps: 1) Download and save the updated HydroInternational.xml file to a suitable location on your hard drive 2) Open the software and go to Components > Engineering Libraries 3) Right click on "Vortex Valve Library" in the list and choose "Add existing Library..." 4) Browse to the location where you saved the HydroInternational.xml file to and double click it. It should now appear in the engineering library. 6) Click the close button. You can now use the updated Hydro International vortex valves. Using Hydro International Vortex Valves To use Hydro International Vortex valves after the above installation: 1) Open the software and go to Components > Vortex Valves. 2) Click the Synchronization Options button (purple book icon) and choose "import from library" 3) Expand Hydrointernational.xml, expand the folder corresponding to the model (CH, SH, CX or SXH), select the vortex valve you'd like to use and click "select" 4) The vortex valve will now appear in the vortex valve manager and can be selected in any composite outlet structure in that model. If you'd like to import another vortex valve, repeat steps 1-4. 5) To use a Hydro International Vortex Valve in a composite outlet structure, first click Components > Composite Outlet Structures. 6) If you have an existing composite outlet structure you'd like to add the vortex valve to, click it first. Click the New Button and choose Vortex Valve. 7) Click the Vortex Valve entry that appeared within your composite outlet structure, then select the desired model from the dropdown next to "Vortex Valve" in the grid at the bottom. Set the Elevation field as well, to define the base/datum. What if I Have Multiple Products? If you have more than one compatible product (such as PondPack and SewerGEMS or SewerGEMS and CivilStorm) and would like to use this updated library in both/each of them, follow the same steps above for either option A or option B, for each product. For option A, you would override each pre-existing copy of Hydrointernational.xml. For option B, you can either save multiple copies of the Hydrointernational.xml file and browse to each respective file within the product's Engineering Library Manager, or you could simply save a single file and browse to that from each product. Using Vortex Valves Created with the Hydro-Brake® Optimum Design Tool If you designed your own vortex valve with Hydro International's Hydro-Brake® Optimum Design Tool, follow these steps: • In a spreadsheet application, open the .CSV file which contains the Hydro-Brake® Optimum data • Highlight the cells containing the values for the Head and Flow • Select Copy, or use the Ctrl and the C keys on your keyboard • In the Bentley Product, click on the Components > Vortex Valves menu • In the Vortex Valves dialog, click on New, then type in an appropriate name • Check that the units for the Head and Flow are correct (if not, right mouse click on each of the two headings in turn, click on Units and Formatting, and choose the correct unit) • Click in the empty cell in the Head column • Press the Ctrl and the V keys on your keyboard to paste in the data:

It sounds as if you are talking about "clash detection" between buried utilities. That's not part of our hydraulic analysis products. Instead, Bentley has some wonderful tools for Subsurface Utility Engineering which can perform clash detection and produce great looking 3-D design graphics. You may want to look into our Open Roads Technology. www.bentley.com/.../OpenRoads+Technology.htm
