Mohamed, I didn't realize this was the same model that Tom had already looked at for you two weeks ago. It also looks like he had gone over which air valves that you should have set the property for "Treat Air Valve as Junction?" option to 'False' for. You can find the discussion in this post: communities.bentley.com/.../106035 ;pi20068scroll=false I have also installed the version of the software that you are using (08.11.04.50) and was able to run the model without getting a network unbalanced user notification while only using 350 trials. When I was computing the model I only had air valves AV-4 and AV-10 set to False because those were the ones Tom previously suggested you may want to do this with. I noticed that when you sent the model in, however, that you had many more of the air valves "Treat Air Valve as Junction?" set to "False". Was there a reason that you did this? Regards, Mark

Forum Post: RE: Problems when only one pump working
Mark, Thanks a lot for your cooperation and response 1- I did what mark said exactly (all valves are set true for "Treat Air Valve as Junction" except AV4 and AV10) and it works very good while all pumps are running but if you try to let one but work alone or two pumps (instead of four) you will get negative pressure any where so, I tried to eliminate this by set some AVs to true but it fails . 2- my model is a network for four deep wells and it is collected together in 600 mm pipeline going to water treatment plant. some times you need to operate one pump or two not always four pumps will work together. I need to know what I have to do to achieve this successfully with no errors.

Forum Post: RE: Problems when only one pump working
Look at the hydraulic profile of the pipeline (View > Profiles). When all of the pumps are on, the HGL will be high and sloping and above the high points. As you turn off pumps, the HGL drops and will fall below the ground elevation at high point (i.e. negative pressure). If you have air valves at the high points, they will maintain the pressure at zero when they open and prevent negative pressure. However, you may get negative pressure downstream at high points that do not have active Air Valves. Remember to check whether the pressure at any point drops below the vapor pressure of water because that is physically impossible.

Forum Post: RE: Problems when only one pump working
Thanks Tom, 1- what i have to do if i get negative at high point that do not have air valves (noting that network is already done )? 2- What i have to fo if i found that pressure at any point drops below the vapor pressure of water ?

Wiki Page: General SewerGEMS For ArcGIS [FAQ]
Applies To Product(s): Bentley SewerGEMS Version(s): V8 XM Environment: N/A Area: N/A Subarea: N/A Original Author: Jesse Dringoli, Bentley Technical Support Group How do I open an existing SewerGEMS model inside ArcMap? First, open ArcMap. Then, click the SewerGEMS V8i menu, choose "Project" > Add Existing Project. Select your SewerGEMS model and then click the blue folder icon in the next window, to attach a geodatabase. A separate geodatabase is necessary for ArcMap to interact with the SewerGEMS model. It is recommended that you save a new geodatabase. For example, name it MyModelgdb.mdb and save it in the same folder as your SewerGEMS model. Ensure that you assign the correct coordinate system/spatial reference, before clicking OK in the window that shows the blue folder icon. When you click OK, the Table of Contents will be populated with the SewerGEMS element types and your model should appear. You may need to use the zoom extents button or zoom to an element using the search button at the top of the SewerGEMS properties window. How do I create a new SewerGEMS model inside ArcMap First, open ArcMap. Then, click the SewerGEMS V8i menu, choose "Project" > Add new project. Choose a location to save the SewerGEMS model and then click the blue folder icon in the next window, to attach a geodatabase. A separate geodatabase is necessary for ArcMap to interact with the SewerGEMS model. It is recommended that you save a new geodatabase. For example, name it MyModelgdb.mdb and save it in the same folder as your SewerGEMS model. Ensure that you assign the correct coordinate system/spatial reference, before clicking OK in the window that shows the blue folder icon. When you click OK, the Table of Contents will be populated with the SewerGEMS element types and you can now lay out or import your SewerGEMS model. How can I convert my GIS to a SewerGEMS model inside ArcMap? First, follow the steps above for creating a new SewerGEMS model. Then, use Modelbuilder to import the GIS. Modelbuilder is located under the "Tools" menu inside the SewerGEMS 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. What is a Geotable? A geotable is similar to a flextable, but determines which fields/attributes are included in the SewerGEMS geodatabase when working inside the ArcGIS platform. ArcMap interacts directly with the personal geodatabase associated with the SewerGEMS model, not the SewerGEMS database (.swg.mdb). The fields selected in the geotable are the fields linked between the SewerGEMS model database and the geodatabase. ArcMap can then apply symbology effects from the available geotable fields. Basically it determines the fields available in ArcMap's attribute tables. Which versions of SewerGEMS support which versions of ArcGIS? See below article: Compatibility Chart Note that versions of ArcMap earlier than the ones listed in this article are also supported. The chart shows the latest available versions that were fully certified. Since the SewerGEMS menus always show up in Arcmap, am I always using a SewerGEMS license? What if I want to use ArcMap without SewerGEMS? As of version 08.11.01.21, SewerGEMS license utilization only occurs when you open a SewerGEMS project (Via SewerGEMS > View > Project manager). For previous versions (08.11.00.08 and below), license utilization will always occur. For information on un-integrating older versions of SewerGEMS with ArcMap, see problem number 35731 in the Knowledgebase. After working on a project in ArcGIS mode and saving a .mxd, why does the SewerGEMS model not appear when reopening the .mxd? After reopening the map, you must first load the SewerGEMS project, under SewerGEMS > View > Project Manager. When working in ArcGIS mode, why are the tools in the SewerGEMS layout toolbar grayed out? First, you must open or create a SewerGEMS model in your current map, using the Bentley SewerGEMS > Project menu. (see further above) 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 SewerGEMS > View > Apply SewerGEMS renderer. What is the easiest way to color code SewerGEMS elements inside the ArcMap platform? Click the element type layer from the table of contents, then click the Bentley SewerGEMS V8 menu, choose Tools > Layer Symbology. This tool will allow you to use the familiar SewerGEMS color coding interface to automatically create ArcMap symbology entries. When annotating or color coding in the ArcMap platform, why aren't all the SewerGEMS attributes available? The attributes available to color code/annotate on are dictated by the attributes included in the geotables. So, click the Bentley SewerGEMS V8 menu > View > Flextables. In the Flextables manager, open the "Geotable" corresponding to the element type in question. Use the yellow 'edit' button to choose the attributes thatwill be available to color code/annotate on.

Wiki Page: How do I create a new WaterGEMS or SewerGEMS model inside ArcMap?
Applies To Product(s): Bentley WaterGEMS, Bentley SewerGEMS Version(s): 08.11.xx.xx Environment: N/A Area: Modeling Subarea: Original Author: Akshaya Niraula, Bentley Technical Support Group [Scroll down for a video] The steps below will show how to create a new project in WaterGEMS. The same steps can be applied to SewerGEMS. 1) Open WaterGEMS for ArcMap. 2) Click the WaterGEMS V8i menu, choose "Project" > Add new project. 3) Choose a name for the project and location to save the WaterGEMS model. Click the "Save" button to proceed to the next step. 4) Click the blue folder icon in the 'Attach Geodatabase' window to create a new geodatabase This is necessary because WaterGEMS interacts with ArcMap through this separate personal geodatabase (.mdb file). Note: If you get a message that says "WaterGEMs project cannot be a geodatabase" this means that the name you tried to give your geodatabase has the .wtg extension in it. Simply remove the extension and your new geodatabase will be created. Ensure that you assign the correct coordinate system/spatial reference, before clicking OK in the 'Attach Geodatabase' window. When you click the "Ok" button, the Table of Contents will be populated with the layers for WaterGEMS element types and you can now lay out or import your WaterGEMS model.

Forum Post: RE: Problems when only one pump working
1, If you get a negative pressure at a high point, that means that the system is a siphon at that location. It is best to put an active air valve at that point (treat at junction = false). 2. If the pressure drops below the vapor pressure, the siphon will not work. You definitely need an active air valve there. Pumping downhill over multiple high points is always going to be a tricky design. You need air valves at all high points so you can fill the pipeline. However, once the pipeline is running, only those that would have pressure below 0 need to be modeled as active air valves (treat as junction = false). The others can be set to true.

Wiki Page: Negative Pressures
Applies To Product(s): Bentley WaterGEMS, Bentley WaterCAD Version(s): 08.11.XX.XX Environment: N/A Area: Modeling Subarea: Original Author: Dan Iannicelli, Bentley Technical Support Group What does it mean when a node reports a negative pressure? A negative pressure occurs when the hydraulic grade is below the physical elevation of a node. If WaterCAD/GEMS says the pressures will be negative, then in all likelyhood you will have problems. Assuming all data input has been checked, there are usually two general causes of negative pressure: 1. Trying to serve a customer at too high of an elevation. This will show up as low/negative pressure at any demand. You need to increase pump head or adjust pressure zone boundaries. 2. Some restriction in the system. This will show up as good pressure during low demand and poor pressure at high demand. You need to look at the model results and see if the pipes are too small causing excess head loss or the pumps are inadequate such that they are running far off to the right of the curve. You need to upsize the pipes or pumps accordingly. You should also check your demands for errors. Since your demands are likely based on historic averages, a significant decrease in pressure may skew the results, since the demands would likely be decreased in that condition. You may consider using pressure dependent demands or flow emitters. You may also consider conducting a transient analysis using Bentley HAMMER, if the problem occurs at a transmission main. Why do I get a negative pressure at a high point in my system? Shouldn't the pump add enough head to push the water over the hill? By default, pumps only consider the boundary conditions (reservoirs and tank elevations) in your system. So, the pump will add enough head to lift the water to the downstream known hydraulic grade. It does not consider junction elevations inbetween. If you are using WaterCAD or WaterGEMS V8i, you should add an Air Valve element at the high point to properly model this situation. By placing an air valve at the high point, the pump sees the air valve elevation as its downstream boundary condition for instances in which pressure would have otherwise been negative at the high point. For any air valve that is expected to be open in this way, ensure that you select "false" for the "Treat air valve as junction?" attribute. For more on this, see this technote . Another alternative to resolving negative pressures to take into consideration is installing a PSV at the downstream end of the system with a hydraulic grade equal to the highest point in the system. What will I need to do if I have negative pressures at high point in my system that does not have air valves installed? If you get a negative pressure at a high point that means the system is a siphon at that location. It is best to put an active air valve at that point (Treat as Junction? = False). If I find that pressure at any point in my system drops below vapor pressure what do I need to do? If the pressure drops below the vapor pressure, the siphon will not work. You definitely need to install an active air valve there (Treat as Junction? = False). This will also help provide protection against a vapor pocket collapse that would cause a transient to occur. Discussion: A negative pressure means that the calculated hydraulic grade is below the physical elevation of the element. You should closely examine your node elevations and boundary conditions (reservoir/tank hydraulic grades) to make sure they are correct. It is common for this to occur on the suction side of the pump, due to the elevation that you entered for the nearby reservoir. If the pump is off, then it is likely that the reservoir elevation is set to be lower than the pump elevation. Creating a profile of the area in question (physical elevations and hydraulic grades) should give you a good visual idea of what is going on. Note that negative pressures will not prevent the model from computing - the messages that you get about these are just informational. WaterCAD/GEMS still assumes that the pipes are pressurized and no vapor pockets will form. It basically just computes the hydraulic grade based on the system conditions and other data input, and then reports the pressure as the difference in head between that and the physical elevation. If the negative pressures occur at high points in the system, you probably would have an air valve at that point so you can fill the pipeline. However, once the pipeline is running, only those air valves that would have a pressure below 0 need to be modeled as active air valves (Treat as Junction? = False). The others can be set to 'True'.

Forum Post: RE: Problems when only one pump working
One more thing Tom, my wells network will be connected to an existing 600 mm pipeline as clarified in the model. Now i get negative pressure at points which have no air valve and it can not be added so, i suggest using PSV near pipeline end to eliminate negative pressure at that point Is it good idea or you have a better recommendations?

Forum Post: RE: Problems when only one pump working
Using a PSV (or a small turbine to help recover some energy) at the end of the system may be a valid option, but whether or not you should do it depends on other factors that need to be considered, some of which cannot be conveyed by the model alone. You as the engineer will ultimately need to make the decision based on everything you know about the system, how it is connected, other needs and requirements, etc. To help, you may want to look around to see if there are any scholarly articles on the subject. You can also do a search on this forum for past discussions on the topic. Of course, if you have questions on any assumptions with your Bentley modeling software that would be relevant with such a decision, this would be a good place to confirm.

Wiki Page: Using Darwin Designer
Applies To Product(s): Bentley WaterGEMS, Bentley WaterCAD (with additional license configuration) Version(s): V8 XM and V8i Environment: N/A Area: N/A Original Author: Scott Kampa, Bentley Technical Support Group Overview The purpose of this TechNote is to discuss common steps to design new pipe layouts and pipe rehabilitation projects using Darwin Design in Bentley WaterGEMS. Additional information can be found in the WaterGEMS Help menu. A free webinar demonstrating Designer is also available here: Optimize Design and Rehabilitation with Darwin Designer Background Darwin Designer is an efficient method of designing new pipe layouts and pipe rehabilitation projects. It allows the user to design pipes for an existing model either manually or, with efficient genetic algorithms, in a more automated fashion. It allows for multiple design candidates to be presented so the best possible solution to a given system can be found. Solutions can also be exported into a new scenario for use in an existing water system. Darwin Desginer is included with a license for Bentley WaterGEMS V8. It is also available in Bentley WaterCAD V8 with an additional license configuration. Getting Started Darwin Designer is accessed by going to Analysis > Darwin Designer, or by clicking the Darwin Designer icon above the drawing pane. Once Darwin Designer is open, click the New icon in the upper left select “New Designer Study”. An item will appear in the window on the left, and a series of tabs will appear at the top right. Next, choose either “New Manual Run” or “New Optimized Run,” depending on the type of study you will be conducting. A new item will appear below the name of the design study. These can be renamed. The next step is to create your demand or rehabilitation groups. As stated above, Darwin Designer can be used to design new pipes or rehabilitate existing pipes. By entering pipes or pipe groups into these tabs, the program will know what type of study is being done. In other words, new pipe design and existing pipe rehabilitation must be done in separate Designer studies. It can be efficient to apply more than one pipe to a given design or rehabilitation group. Darwin Designer will assign the same diameter to each pipe in the group (or all of the pipes in the same rehabilitation group will receive the same rehab action). The steps to add pipes to a new design or rehabilitation group are the same. First, click the New icon. A new pipe group label will appear. A collection field will appear under the column “Element IDs.” Click in this cell and then click the ellipsis (“…”) button. This will open a new dialog where you can select the elements to go into the group. Choose the “Select from Drawing” icon to open the Select toolbar. You can add or remove elements by activating the Add or Remove icon (Add is active by default). You can also add elements by drawing a polygon around a given group, or using a query. Selecting by selection set is available under the Query selection as well. Once completed, click the green checkmark icon. You will return to the previous dialog. Click Okay to return to Darwin Designer. Note that the collection cell will say that items are now included. Next, go to the Cost/Property tab. Here you will enter the cost information for a given pipe size or rehabilitation action. To create a new item, choose the New icon and choose either “Design Option Groups” or “Rehabilitation Option Groups.” Next in the table on the right, begin to enter data. For Design Option Groups, enter the material, diameter, Hazen Williams C factor, and the Unit Cost. For Rehabilitation Option Groups, you will include an action, and then the diameter function, unit cost function, and roughness function for the pre- and post-rehabilitation scenarios. Now go to the Design Type tab. Here you can select the Objective Type, and available budget for the project. Now return to the Design Events tab. Choose the Representative Scenario from the pulldown. Darwin Designer will use data from the selected scenario when running the analysis. Next, select the New icon to create a new event. When you do this, you will see new information in the upper right of Designer dialog. Some of the fields will be unavailable to editing; this is pulled directly from the scenario assigned to the event. Items like minimum and maximum pressure and velocity will assure an efficient Designer run. In the bottom right part of the Designer dialog, you can assign boundary overrides, demand adjustments, and pressure and flow constraints. These are used when the results calculated in the representative scenario might be different from when is observed in the field or allow a different set of constraints for certain elements. Manual Design Run Manual selections are used to force Darwin Designer to use specific designs in calculating costs of a new network design or existing rehabilitation study. The difference between the manual design run and the optimized design run is the Manual Selection column in the Design Groups and Rehabilitation Groups tabs. After you select a table to use for a group, you then set that group to use a specific pipe size or specific rehabilitation action. Manual runs can be useful when you want to test hand calculations you have made or to reproduce an optimized design with some forced manual overrides for some pipes. You could also create a manual design run where you force the groups of pipes to specific sizes, since optimized design runs will choose the best fit. To create a new manual design run, click the New icon and select “New Manual Design Run.” Go to the Design Group tab and select the Cost/Properties to be associated with the pipe group. Next, choose the size of pipe to be used for the manual run under the Manual Selection column. When you click the drop down, you will see a list of the pipe diameters assigned to the Cost/Property selection. It is possible to globally set the Cost/Properties column, but the Manual Selection column must to done individually. To compute, highlight the manual design run and click the Compute icon. After completion, a solutions will be available to view and export to the model. To view the results, highlight Solutions. This will display the fitness and total cost for each solution. To see the results from individual solutions, choose one of the solutions from the list. You will be able to view the breakdown of costs and the simulated model results for the solution. Optimized Design Run The optimized design study uses a genetic algorithm to find the best possible solution available within certain parameters. The optimized design study has no true optimality and only knows the best solution relative to other solutions already found during computation. However, the optimized design study runs through a large number of possible solutions and can often find a very good solution to fit the model. The process is similar to the manual run. Click the New icon in the upper left and choose New Optimized Design Run. Under the Design Group or Rehabilitation Group tab, choose the Cost/Properties field associated with the pipe group. You do not need to manually select the size since Darwin Designer will do that for you. Once completed, click the Compute button. Darwin Designer will then try different pipe sizes or rehabilitation actions that fall within the constraints entered in the Design Event tab until the best solution is found based on the objective type. Darwin Designer will continue until it finds the best solution available. The results are viewed just as the manual run, however there is an option to view as many as ten solutions. See the Tips section below for more information about this. Updating the Model If you are satisfied with the results, you can export to a new scenario, as well as new physical and active topology alternatives. To do this, highlight the solution you wish to export. The “Export to Scenario” icon will become active. Choose this icon and a new window will appear. To export to a new scenario, check the “Export to Scenario?” box. Do the same for the alternatives. With the check boxes selected the new results will be exported to new physical or active topology alternatives. If you export to a scenario and do not export to an alternative (by unchecking the associated box or boxes), the data for that alternative type will be exported to the Base alternative. Note: The data in your original model will not change unless you use this export feature Manual Cost Estimating Manual Cost Estimating is a method of estimating the construction cost of piping. This feature is available in Darwin Designer even for WaterCAD users with limited licensing features, such as no license for optimized or manual Designer runs. After creating a new Designer study, go to the Cost/Properties tab. Select the New icon and choose “Design Option Groups.” Enter the material, Hazen Williams C factor, and unit cost for each diameter of pipe. Next, go to the Design Group tab and click the New icon to create a new group. In the Element ID column, click the ellipsis button and choose the element or elements to be included. For Manual Cost Estimating, no information is needed in the tabs for Design Event, Rehabilitation Groups, or Design Type. Next, click the New icon from above the left column and choose New Manual Cost Estimate Run. Highlight this run and click the “Is Active?” box for any pipe group you want included in the analysis. Choose the Design Option Group entered in the Cost/Properties tab in the Cost/Properties column. You can use the Global Edit feature to assign these. The other item to set up is the “Use Diameter from Representative Scenario” item. If this box is checked, this will assure that the costs are based on the diameter of the pipes in the scenario. If it is unchecked, you will need to manually enter the scenario to be used. To compute the Manual Cost Estimating run, click the Compute icon. You will get a single solution. Highlight “Solutions” to get an overview of the total cost. Highlight “Solution 1” to view a breakdown on how the costs are distributed Tips After computing a designer study, you will sometimes see results that do not have a good fitness or do not make sense. Below are a few general tips to look at. More information on Darwin Designer can be found in the WaterGEMS Help documentation. If you are getting strange results, you can try the following: First, make sure you are using the correct design data, including the correct representative design scenario and that scenario includes all pipes to be sized by Darwin Designer. Second, make sure that the representative design scenario runs successfully within Bentley WaterGEMS V8i. If it does not, then Designer will not be able to function correctly. Third, make sure that the correct demands are present. For EPS representative scenarios, make sure your patterns are correct and that you are using the correct time from start value in your design events. Fourth, make sure that you have applied the correct and necessary boundary conditions, including tank levels, pump operation, etc. Fifth, make sure that the range of pipe sizes and rehab actions you are using are reasonable and that you are allowing Darwin Designer a sufficient range of pipe diameters to come up with a reasonable design. Last, make sure that you have a reasonable number of design and/or rehab groups Since Darwin Designer applies a competent genetic algorithm to optimize the design, it does not require or have any domain-specific knowledge about the water system. This can have a side-effect for some design cases, like giving up-or-down pipe sizes. In particular, the solutions are evaluated by comparing the fitness values of solutions. Darwin Designer will assume a pipeline with pipe sizes that go up and down (to meet required pressures as closely as possible) is better than one that has a constant size that exceeds the pressures at some locations, since there is no specific penalty assigned to the fitness of a solution that has pipes that change up and down in size. It is up to you to control the eventual design and this can be done by different means. The first means is simply to make manual adjustments to a design after Darwin Designer has finished. Cleaning up a design may technically move you away from the cheapest design, but an inexpensive design that won't be constructed is of little use. You may find that not much cleaning up is necessary. Quick edits to diameters or rehab actions like can be performed effectively in Darwin Designer by using a manual design run. Another thing to consider when analyzing a Darwin Designer design is whether the chosen pipe sizes are a function of the lengths of pipe in your model. More information on this can be found in Help under the topic “Advanced Darwin Designer Tips.” Another means of achieving more constructible designs from Darwin Designer is to group in the same group pipes that would be constructed the same size. For example, a rising main would most likely be constructed a single size, and it would thus make sense to include all the model pipes that make up the rising main in the same design group. What you don't want to do by grouping pipes is artificially design the system even before you have had a chance to optimize it. When using the optimized designer run, you can change the results simply by changing some of the parameters under the Options tab. For instance, changing the Random Seed to another value will yield different results, possibly a solution that is better than the first pass through the simulation. You can also change items like the penalty factor, probability, population size, and maximum trials. More information on this can be found in Help under the topic “Advanced Darwin Designer Tips.” WaterGEMS and WaterCAD also come with sample models and lesson files to help with the general setup of a Darwin Designer study. This is a good resource and can allow you to view completed models. The steps for the lesson files can be found in under Help > Quick Start Lessons.
