How to Download EPANET Z and Why You Should Try It

If you are interested in modeling water distribution systems, you have probably heard of or used EPANET, a software application developed by the US Environmental Protection Agency (EPA) that can simulate the hydraulic and water quality behavior of pressurized pipe networks. But did you know that there is a modified version of EPANET that can integrate mapping data from the internet? It is called EPANET Z, and it is developed by Zonum Solutions, a company that provides geospatial solutions for water resources management. In this article, we will explain what EPANET Z is, how it differs from EPANET, how to download and install it on your computer, how to use it to create and analyze your water distribution network, and what are its benefits and limitations.

What is EPANET Z and How Does It Differ from EPANET?

EPANET Z is a modified version of EPANET that integrates mapping data from the internet

EPANET Z is based on the source code of EPANET 2, which is public domain software that can be freely copied and distributed. However, unlike EPANET, which uses a plain background for displaying the network, EPANET Z adds the ability to view data from Google Maps, Yahoo Maps, or Virtual Earth in the network’s backdrop. This way, users can see their network on real-world maps, such as satellite images, street maps, or terrain maps. The derived version of EPANET is called EPANET Z.

EPANET Z allows users to view and edit their water distribution networks on different map sources

With EPANET Z, users can not only view their network on different map sources, but also about the network and the simulation, and a menu bar that provides access to various options and functions of EPANET Z. Users can also open multiple network files and switch between them using tabs.

EPANET Z allows users to import or create their network data using different tools

Users can import their existing network data from EPANET files (.inp) or other formats, such as Excel files (.xls), text files (.txt), or GIS files (.shp). Users can also create their network data from scratch using EPANET Z tools, such as drawing nodes and links, copying and pasting elements, importing coordinates from text files, or generating random networks. Users can also use the EPANET Z Toolbox, which is a collection of tools that can help users to create and modify their network data, such as converting units, scaling elevations, adding demands, or adjusting diameters.

EPANET Z enables users to select and switch between different map sources for their network backdrop

Users can choose from three different map sources for their network backdrop: Google Maps, Yahoo Maps, or Virtual Earth. Users can also switch between different map types, such as satellite images, street maps, terrain maps, or hybrid maps. Users can also adjust the transparency of the map layer to make the network more visible. Users can also refresh the map layer to update the map data from the internet.

EPANET Z supports various coordinate systems and units for network data

Users can specify the coordinate system and the units for their network data using EPANET Z. Users can choose from different coordinate systems, such as geographic (latitude and longitude), projected (UTM or State Plane), or local (arbitrary). Users can also choose from different units for length, flow, pressure, or quality. Users can also convert their network data from one coordinate system or unit to another using EPANET Z tools.

EPANET Z performs hydraulic and water quality simulation using the same engine as EPANET

Users can run hydraulic and water quality simulation of their network using EPANET Z. Users can set the simulation options, such as time steps, duration, patterns, controls, or reactions, using the same menus as EPANET. Users can also view the simulation results, such as pressures, flows, velocities, or concentrations, using the same tools as EPANET. Users can also generate reports and graphs of the simulation results using EPANET Z.

Benefits and Limitations of EPANET Z

EPANET Z offers several advantages over EPANET, such as:

Visualizing the network on real-world maps

One of the main benefits of EPANET Z is that it allows users to see their network on real-world maps, such as satellite images, street maps, or terrain maps. This can help users to better understand the spatial context of their network, such as the location of water sources, demand areas, or topography. This can also help users to validate and verify their network data, such as elevations, lengths, or coordinates.

Editing the network data directly on the map

Another benefit of EPANET Z is that it allows users to edit their network data directly on the map. For example, users can move, add, or delete nodes and links by dragging and dropping them on the map. Users can also edit the properties of the network elements, such as elevations, diameters, demands, or quality parameters, by using the same dialog boxes as EPANET. This can make the network creation and modification process more convenient and intuitive.

Comparing the network with other spatial data layers

A third benefit of EPANET Z is that it allows users to compare their network with other spatial data layers, such as land use, population, or infrastructure. Users can overlay their network on top of these data layers and adjust the transparency of each layer to see the relationship between them. This can help users to identify potential problems or opportunities for their network, such as water demand patterns, leakage areas, or expansion possibilities.

Exporting the network data to other formats, such as KML or Shapefile

A fourth benefit of EPANET Z is that it allows users to export their network data to other formats, such as KML or Shapefile. These formats are widely used in geographic information systems (GIS) and can be easily imported into other software applications for further analysis or visualization. This can help users to share their network data with other stakeholders or collaborators, or to integrate their network data with other spatial data sources.

EPANET Z also has some drawbacks, such as:

Depending on the internet connection speed and availability

One of the main limitations of EPANET Z is that it depends on the internet connection speed and availability to access the mapping data from the web. If the internet connection is slow or unavailable, EPANET Z may not be able to load the map data properly or at all. This can affect the performance and functionality of EPANET Z and may cause frustration for users.

Not being compatible with some EPANET extensions, such as MSX or RTX

Another limitation of EPANET Z is that it is not compatible with some EPANET extensions, such as MSX or RTX. These extensions are developed by EPA or other organizations to enhance the capabilities of EPANET for modeling complex water quality processes or real-time operations. Users who want to use these extensions will not be able to use EPANET Z and will have to use EPANET instead.

Not being officially supported or endorsed by EPA or other organizations

A third limitation of EPANET Z is that it is not officially supported or endorsed by EPA or other organizations that are involved in water distribution system modeling and management. EPANET Z is developed by Zonum Solutions, a private company that provides geospatial solutions for water resources management. Users who encounter any issues or problems with EPANET Z will have to contact Zonum Solutions for support and assistance. Users who want to use an official and reliable version of EPANET will have to use EPANET instead.
