Finally, we will provide you with some useful resources and support options to help you get started with EPANET 2.0.
Step 1: Go to the official EPA website and choose the version that suits your needs
The first step to download EPANET 2.0 is to go to the official EPA website for EPANET at . Here you will find a brief introduction to EPANET, as well as links to download the software, manuals, toolkits, extensions, source codes, updates, and related resources.
There are two main versions of EPANET 2.0 available for download: a self-extracting installation program (EXE) and a non-installing software (ZIP). The installation program will guide you through the steps to install EPANET on your computer, while the non-installing software will allow you to run EPANET without installing it.
The installation program is recommended for most users who want a quick and easy way to install EPANET on their computer. The non-installing software is recommended for advanced users who want more control over where to place the software files or who want to run multiple versions of EPANET on their computer.</p Step 2: Download and install the software on your computer
The second step to download EPANET 2.0 is to choose the version that suits your needs and click on the corresponding link to download it. The download process may take a few minutes depending on your internet speed and connection.
If you chose the installation program, you will need to run it after downloading it. A window will pop up asking you to accept the license agreement and choose the destination folder for EPANET. You can also create a shortcut on your desktop or start menu for easy access. The installation process will take a few seconds and you will see a confirmation message when it is done.

If you chose the non-installing software, you will need to unzip it after downloading it. You can use any software that can extract ZIP files, such as WinZip, 7-Zip, or Windows Explorer. You can place the extracted files in any folder you want, but make sure you keep them together. You can also create a shortcut on your desktop or start menu for easy access.
Step 3: Run the software and explore its features
The third step to download EPANET 2.0 is to run the software and explore its features. You can do this by double-clicking on the EPANET icon on your desktop or start menu, or by navigating to the folder where you installed or extracted EPANET and double-clicking on the EPANET executable file (EPANET2W.EXE).
When you run EPANET for the first time, you will see a welcome screen with some basic information about the software and a link to the user's manual. You can close this screen by clicking on the X button at the top right corner.
You will then see the main window of EPANET, which consists of a menu bar, a toolbar, a status bar, and a workspace. The menu bar contains various commands and options for working with EPANET, such as opening, saving, editing, running, viewing, and analyzing projects. The toolbar contains buttons for quick access to some of the most common commands and options. The status bar shows messages and information about the current project and simulation results. The workspace shows a graphical representation of the network layout and properties.
You can start exploring EPANET's features by opening an example project that comes with the software. To do this, go to File > Open and choose one of the files with the .INP extension in the EXAMPLES folder. You will see the network diagram of the project in the workspace, along with some labels and symbols indicating the nodes, pipes, pumps, valves, tanks, reservoirs, and other elements of the system.
You can zoom in or out of the network diagram by using the mouse wheel or by clicking on the magnifying glass buttons on the toolbar. You can also pan around the network diagram by holding down the right mouse button and dragging it. You can select any element of the system by clicking on it with the left mouse button. You can then view or edit its properties by clicking on the Edit button on the toolbar or by pressing F2.
You can run a hydraulic simulation of the project by clicking on the Run button on the toolbar or by pressing F9. This will calculate how water flows through each pipe, node, pump, valve, tank, and reservoir in the system under different conditions and scenarios. You can view the simulation results by clicking on any element of the system and choosing one of the options from the View menu or from the drop-down list on the toolbar. You can also plot the simulation results as graphs or tables by choosing one of the options from the Report menu or by clicking on the report button on the toolbar.
You can run a water quality simulation of the project by clicking on the Quality button on the toolbar or by pressing F8. This will track how different water quality constituents, such as chlorine, fluoride, or contaminants, move and change within the system over time. You can view the water quality results in the same way as the hydraulic results, by clicking on any element of the system and choosing one of the options from the View menu or from the drop-down list on the toolbar.
EPANET 2.0 Features and Capabilities
Now that you know how to download and run EPANET 2.0, you might be wondering what makes it so useful and powerful for water distribution system analysis. In this section, we will briefly describe some of the main features and capabilities of EPANET 2.0 that set it apart from other software applications.
One of the core features of EPANET 2.0 is its ability to simulate the hydraulic behavior of water distribution systems. EPANET 2.0 can model complex pipe networks with various types of elements, such as nodes, pipes, pumps, valves, tanks, and reservoirs. EPANET 2.0 can also handle different types of demands, such as constant, variable, or patterned demands, as well as different types of controls, such as time-based, rule-based, or feedback-based controls.
EPANET 2.0 uses a robust and efficient algorithm to solve the hydraulic equations that govern the flow and pressure in each element of the system. EPANET 2.0 can perform both steady-state and extended-period simulations, meaning that it can calculate the hydraulic conditions at a single point in time or over a long period of time with varying inputs and outputs.
EPANET 2.0 can also perform sensitivity analysis, calibration, and uncertainty analysis for hydraulic parameters, such as pipe roughness, pump curves, valve settings, or demand patterns. EPANET 2.0 can help you estimate these parameters from field measurements or from other sources of information.
