No, you take water at the source, fill a bunch of bottles and every few hours measure residual. The chlorine values should plot as a straight line on a semi-log graph.

Wiki Page: Constituent concentration sensitivity to pipe roughness
Product(s): Bentley WaterGEMS, WaterCAD Version(s): All Environment: N\A Area: Modeling Subarea: N\A Problem Will chlorine (constituent) concentration change if I change the pipe roughness? Solution When the Decay reaction rate is of the first order (or higher), the concentration at time t is represented by: Ct = C0e-Kt where K = kbulk + kwall x kf x (Rh(kwall + kf))^(-1) and kwall = α / Hazen Williams C Factor and α ranges from 0 to 100. So, the constituent concentration from above equations, we can see, is related to pipe roughness factor. This will not be true when the decay reaction is of the 0th order. Note: in WaterCAD and WaterGEMS, the Constituents dialog has a check box for "Is Rougness Correlated". See Also

Wiki Page: Hydraulics and Hydrology product licensing (activation)
Applies To Product(s): WaterGEMS, WaterCAD, SewerGEMS, SewerCAD, StormCAD, CivilStorm, HAMMER, PondPack Version(s): 08.xx.xx.xx Environment: N/A Area: Licensing Subarea: Original Author: Scott Kampa, Bentley Technical Support Group How does licensing / activation work for Bentley Hydraulic and Hydrology products? Licensing for SELECT and non-SELECT users both use a server name and activation key in order verify the product, the size of the license, and features like AutoCAD integration. All products licensed to a certain site will be on a single activation key. For instance, a user may have licenses for WaterGEMS and SewerGEMS, both contained within their Site Activation Key. If so, they would not be able to license and use WaterCAD. A given activation key will also contain the size of the license. For example a WaterGEMS license may be 1000 pipe license, or a PondPack license may be a 3 pond license. The size of the license is important because it governs the model size that can be analyzed. If you have a 1000 pipe license, but try to compute a model with 1500 pipes, you will get a notification stating that the number of pipes in the model exceeds the size of the license. A user can get information on the details of a license in a couple of places. First, a user can go to Start > Program > Bentley > (product name) > Municipal License Administrator . Select "Refresh Configurations" and your products will appear. The column labeled "Total" shows the number of licenses for a give product. The column labeled "Features" shows the size of the license, as well as any other features, such as AutoCAD integration. Second, the user can go to Start > Program > Bentley > (product name) > License Management Tool . In the License Checkout tab, you as see the product name, features, and the number of available licenses. The above information pertains to users with and without a SELECT subscription. The steps to activate vary for SELECT and non-SELECT users. Below are some details on the differences, but here are the basic steps. Product Activation The following uses WaterCAD as an example, but applies to all the hydraulics and hydrology products: A. Go to Start > All Programs > Bentley > WaterCAD > License Management Tool >Tools > Product Activation Wizard 1) Choose what type of subscriber you are: Most cases will choose the first option for SELECT Subscriber activaing against a hosted (Bentley) SELECTServer. or 2) NON-SELECT or Node Locked user The third and forth options are less common, but may apply. 3) SELECT Subscriber activaing against a deployed (local) SELECTServer. 4) Evalution Only- No license information Click the "Next" button B. The server name should be entered for you if you choose options 1 or 2. For option 3 you'll need to enter your deployed (local) server name, which your IT department should provide for you. Enter the site activation key. If you have another Bentley product installed you can copy the key from it. Click the "Test Connection" button sometimes shown as "Verify" button to make sure the information is entered correctly and is verified against our servers. Click the "Next" button C. Select your country location Click the "Next" button Finally, check your information and click the "Finish" button SELECT and ELS Licenses SELECT users have an option to either have the license server hosted by Bentley or deployed to a local server at their location, though the vast majority are hosted. Licenses hosted by Bentley will always have the server name "selectserver.bentley.com". If the license server is deployed to the user's location, the server name will be the server with the licensing information. The activation key will vary by location. If you do not know it, contact your Site Administrator (typically in your helpdesk/IT/ department) who should have the original PDF Fulfilment Document containing the license information. If this cannot be located, Site Administrators can find it on the Personal Portal under the button "License Management": The first time you activate the license, a License Activation Wizard may open. You can simply follow the steps to activate the license. If the License Activation Wizard doesn't open, or if you receive a licensing message, you can use the steps found here to activate the license. Generally speaking, SELECT users do not need to check out a license. Once the license is activated and a default feature configuration is set, you should be able to use the product without issue. If you need to disconnect from the network, the product will run in what is called disconnected mode. The product will run in disconnected mode for 30 days without needing to contact the server. You will get a message when open the product, stating that you are running in disconnected mode and the number of days available. So, it is typically not an issue if you need to take a laptop home for the weekend to work on a project for example; the product will still work. Note that the initial "trial" period (before the initial license activation) is 7 days - see "Initial Trial Period" below. If you do need to check out a license for any reason, you can follow the steps found in below in the non-SELECT licenses section. Non-SELECT Licenses Unlike the SELECT license, a non-SELECT license must be checked out. This essentially removes a "seat" of the license from the server and locks it to that computer. So for example if you have a one-seat license and someone checks it out, no other users will be able to license their product. To check out a license, go to Start Programs > Bentley > (Product Name) > License Management tool. When the License Management Tool opens on the top go to Tools > Options. Confirm that the server name is set to "productactivation.bentley.com" or "selectserver.bentley.com" and that a activation key is entered, then click OK. Now, find the product name in the top dialog box, select it and enter a date next to "Checkout Expiration Date". Next, click the "Check Out" button located below the top part of the dialog. You will need to enter an email address (for reference purposes) and the version of the product. Note that if you do not know the product version, you can find this by opening the product and going to Help > About. The version number is in the lower left in brackets next to the date. Once you do this, the license will be checked out. You should see the product name in the bottom dialog. Once completed, it is important to note that this license will not be available for use to other users. If there is only one license, it will need to be checked back in before the product can be licensed by another user. To check the license back in all you need to do is reverse the procedure by highlighting the product name in the bottom dialog and select the "Check In" button. Once you do this, the license will be available to users once again. Initial Trial Period and Disconnected Mode Upon installation of your Bentley Hydraulics and Hydrology product, you will be able to open and use it for up to 7 days before the initial license activation is required. The product will operate at the lowest feature level. For example WaterCAD will only allow up to 10 pipes in the model and will not integrate with AutoCAD. You can confirm this under Help > About > "Size". After the initial activation of the product per the above information, the product only needs to re-activated against the server at least once every 30 days. So like in the example given further above, if you need to go away from the internet for some period of time, the product will still work and will operate in Disconnected Mode for up to 30 days before requiring to communicate with the server.

Wiki Page: How is the wet well Depth (Node) field calculated?
Product(s): SewerGEMS Version(s): 08.11.05.113 Environment: N\A Area: Output and Reporting Subarea: N\A How is the wet well Depth (Node) field calculated? For the GVF-Convex solver: Depth (Node) = Hydraulic Grade - Elevation (Base) For the Explicit (SWMM) and Implicit (Dynamic Wave) solvers: Depth (Node) = Hydraulic Grade - Elevation (Minimum) Why doesn't the Depth(Node) field match the wet well hydraulic grade? Prior to the release of the patch set dated May 25th 2016, the GVF-Convex solver calculated the Depth (Node) field as shown below: If the wet well's "Elevation (Initial)" is less than the upstream pipe's "Hydraulic Grade Line (Out)": The wet well "Depth (Node)" field is calculated by subtracting the wet well's "Elevation (Base)" from the calculated "Hydraulic Grade Line (Out)" value of the upstream pipe. If the wet well's "Elevation (Initial)" is greater than the upstream pipe's "Hydraulic Grade Line (Out)": The wet well "Depth (Node)" field is calculated by subtracting the wet well's "Elevation (Base)" from "Elevation (Initial)". If the latest patch set (dated May 25th, 2016 or later) is applied, the Depth (Node) will no longer user the upstream pipes hydraulic grade.

Wiki Page: How to find volume of water coming from a trace element?
Product(s): Bentley WaterGEMS, Bentley WaterCAD, Bentley HAMMER Version(s): 08.11.XX.XX Environment: N\A Area: N/A Subarea: N\A Problem How can I find the volume of water coming from an element that I set as the trace element in my pipes or my junctions? Problem ID#: 75149 Solution You can't get the volume of water from a trace element in your junctions because junctions do not have a flow property associated with them. You can, however, get the volume of water from a trace element for your pipes using the steps outlined below: 1) Create a user data extension field that is Real(formula) based for your pipes. This type of field allows you to create user data extension and use mathmatical calculations based on other fields. a) Go to Tools > User Data extensions and create a new user data extension for your Pipe element. b) Change the Data Type to Real(Formula) c) In the formula field that appears underneath it click the ellipsis button to open the real formula editor d) In the label field located "Flow" and if it's not set for GPM you'll need to right click on it and change the units to GPM. Once that's set double click on "Flow" to add it to the formula and you should see it appear in the box below the label window. It should look like this: [IdahoPipeResults_PipeDischarge; GallonsPerMinute] e) Now click the multiplication symbol to add it to the formula. f) Locate "Trace(Calculated) (%)" in the label list. Right click on it and change it from % to unitless, which is just the blank value. Now Double click on it to add it to the formula. The final formula will look like this: [IdahoPipeResults_PipeDischarge; GallonsPerMinute] * [IdahoWaterQualityResults_CalculatedTrace; UnitlessPercent] g) Click the "OK" button after entering the formula. This brings back to the user data extension manager. h) Now you'll change the dimension from 'None' to 'Volume', change the storage unit to 'gallons', and change the numeric formatter to 'Volume'. Note what you named and labeled this user data extension and then click 'OK'. 2) Go to Analysis > Calculation Options and double click on the calculation option that is associated with your trace analysis scenario so we can change the properties. The property we need to change is the Hydraulic Time Step. Change the time step to 1 minute because we are using the gallons per minute unit for our flow. Once done close the calculation options window. 3) Compute the model. 4) Go to Analysis > Post Calculation Processor and select all the pipes you need to compute the volumes for. Select your "Start Time" and "Stop Time." Set the 'statistic type' to 'sum'. Change the 'Result Property' to the name of the Real(Formula) user data extension field. In the 'output property' what you will need to do is create another user data extension on the pipe element and set it to a data type of "Real". Set your operation type to 'Set' and hit the calculate button. This gives the volume of water coming from your specific trace source. Note: Using the post calculation processor all the volumes will be added up so if you have a flow at some time that is reversed (i.e. negative flow) then these negative flows will be subtracted from the total volume of the time step you are examining in the post calc processor. If you don't want to have it this way you can use the flow(absolute) field in your user data extension.

Forum Post: RE: Assigning Junctions name using Model Builder while importing AutoCAD Files
Hello Md, I assume that the DXF file includes nodes. If so, and if these include a column with unique identifiers, you should be able to select that column as the Key Field. If there is no column with unique identifiers, there will be a column If the DXF file does not include junctions, the junctions will be automatically created at the ends of the pipes. In such a case the junctions will be given labels using the convention assigned under Tools > Options > Labeling.
