Various scenarios were considered for two networks. The first was a simple hypothetical network from the literature Network 1 in Fig. Open image in new window Fig. DSR demand satisfaction ratio is available flow divided by demand Fig. On the other hand, Network 2 is much larger and, aiming to reflect the entire network, representative results were included. The network was used previously to assess water quality simulation models and was selected in part for this reason Seyoum and Tanyimboh In general, hydraulic and water quality models require extensive calibration for operational use.

However, the various investigations and procedures involved are outside the scope of this article.

The effectiveness of the proposed integrated model must be demonstrated first, followed by fieldwork and any additional validation steps. Steady state conditions were assumed for Network 1 while the hydraulic time step for Network 2 was one hour. Helbling and Van Briesen developed general-purpose empirical relationships between the initial concentration of chlorine and each parameter of the parallel first-order chlorine decay model.

Similarly, Sohn et al. Finally, both k b and k were taken as 1. The wall reactivity coefficient k w requires calibration in practice and would require field data to bring about a significant qualitative improvement in the results.

This research is in progress; the pipe wall reaction was not considered explicitly. Steady state conditions were assumed.

The demand satisfaction ratio is the available flow divided by the demand, i. The results are shown in Figure 1. The expected trends of decreasing chlorine residual and increasing TTHM concentrations with the distance from the source are self-evident. The results confirmed also that the chlorine residual and TTHM concentrations at the supply nodes were always 1. Both models analysed the fast- and slow-reacting components of chlorine and TTHM simultaneously in a single execution.

The deficiencies in pressure influenced the overall performance of the system significantly. As the pressure decreased, the available flow at the demand nodes decreased.

The flow velocities decreased while travel times increased as a result. The simulated results reflected these effects. It was revealed that the concentration of chlorine at node 6 would be less than the minimum requirement of 0.

The demand categories considered were domestic demand, losses or unaccounted for water, and h and h commercial demands for an operating cycle of 24 hours, as shown in Fig. Water age, chlorine residual, trihalomethanes and haloacetic acids were considered.

The hydraulic and water quality time steps were one hour and five minutes, respectively. Allows for time-varying concentration or mass inputs at any location in the network. This capability has been included into both a stand-alone executable program as well as a toolkit library of functions that programmers can use to build customized applications.

EPANET-MSX allows users the flexibility to model a wide-range of chemical reactions of interest, including, auto-decomposition of chloramines to ammonia, the formation of disinfection byproducts, biological regrowth, combined reaction rate constants in multi-source systems, and mass transfer limited oxidation-pipe wall adsorption reactions. Analytics refer to the discovery and interpretation of patterns in data. There are over 50 functions that can be used to open a network description file, read and modify various network design and operating parameters, run multiple extended-period simulations accessing results as they are generated or saving them to file, and write selected results to a file in a user-specified format.

The toolkit is useful for developing specialized applications, such as optimization or automated calibration models that require running many network analyses. It can simplify adding analysis capabilities to integrated network-modeling environments based on computer-aided design CAD , geographical information system GIS , and database packages. A Windows Help file is available to explain how to use the various toolkit functions. It offers some simple programming examples. The toolkit also includes several different header files, function definition files, and.

You can leave the dimensions at their default values for this example. Drawing the Network Nodes We are now ready to begin constructing our network.

First add the reservoir by clicking the button on the Map Toolbar. If the toolbar is not visible then select View Toolbars Map. Then click the mouse on the map at the location where the reservoir belongs. Next we will add the junction nodes. Click the button on the Map Toolbar and then click on the map at the locations of nodes 2 through 7. Finally add the tank by clicking the tank is located.

Drawing the Network Links Next we will add the pipes.

Epanet Java

Lets begin with Pipe 1 connecting Node 2 to Node 3. Click the button on the Map Toolbar. Click the mouse on Node 2 on the map and then on Node 3.

Note how an outline of the pipe is drawn as you move the mouse from Node 2 to 3. Repeat this procedure for pipes 2 through 7. Pipe 8 is curved. To draw it, click the mouse first on Node 5.

Then as you move the mouse towards Node 6, click at those points where a change of direction is needed to maintain the desired shape. Complete the process by clicking on Node 6. Finally, add the pump by clicking the Node 2.

Adding Labels button, clicking on Node 1 and then on The final task in building our network is to add some descriptive labels. Select the button on the Map Toolbar and click somewhere close to the reservoir Node 1.

An edit box will appear. Click next to the pump and enter its label PUMP , then do the same for the tank.

Click the than Text Insertion mode.

At this point we have completed drawing the example network. Your network should look like the one seen by pressing the View Network button above. If the nodes are out of position you can move them around by clicking the node to select it, and then dragging it with the left mouse button held down to its new position. The labels can be repositioned in similar fashion.

To change the value of a specific property for an object we must select the object into the Property Editor shown below. There are several different ways to do this. If the Editor is already visible then you can simply click on the object or select it from the Data page of the Browser. If the Editor is not visible then you can make it appear by one of the following actions: Double-click the object on the map Right-click on the object and select Properties from the pop-up menu that appears Select the object from the Data page of the Browser window and then click the Browsers Edit button.

4. Finally, add the pump by clicking the Node 2. Adding Labels

Whenever the Property Editor has the focus you can press the F1 key to obtain fuller descriptions of the properties listed. Setting Node Properties The nodes in our example network are assumed to have the following properties: Node 1 2 3 4 5 6 7 8 Elevation ft Demand gpm 0 0 0 0 Let's begin by selecting Junction 2 into the Property Editor.

So double click on it, or select it from the Browser and click the Browser's Edit button. Enter the elevation and demand for this node in the appropriate fields.

You can use the Up and Down arrows on the keyboard or the mouse to move between fields. After this, we need only click on another node to have its properties appear next in the Property Editor.Reliability simulation of water distribution systems single -multiquality, Urban Water, 4, It consists of a source reservoir e.

Complete the process by clicking on Node 6. AviOstfeld, D. The distribution layout used here is tree system or dead end system which is according to the layout of the Kathgarh area. On the other hand, Network 2 is much larger and, aiming to reflect the entire network, representative results were included. The fire hydrants are placed at 50 to m intervals on straight runs, and on street junctions.

A 1-hour pattern time step is a more typical number and is the default assigned to new projects. The value of k f depends on the molecular diffusivity of the reactive species and the turbulence of the flow.
