EPANET is a specialized Windows program used throughout the world to model water distribution systems. It was developed as a means for understanding the movement and destination of drinking water constituents. Please note, you can integrate the core functionality of this tool into QGIS via plugin.

Goal

With this application, engineers and consultants can design new water infrastructure, retrofit existing framework, optimize operations of tanks and pumps. It is also possible to reduce energy usage, analyze water quality problems and prepare for emergency situations. In addition, users have the ability to model contamination threats and evaluate resilience to natural disasters or security threats.

Interface

The graphical user interface provides a visual editor that simplifies the process of building pipe network models as well as editing their properties and data. Various data reporting and visualization tools may be used to assist in interpreting the results of an analysis, including color-coded maps, data tables, energy usage, reaction, calibration, time series graphs and profile plots.

Functionality

The software allows you to perform simulations of the hydraulic and water quality behavior within pressurized pipe networks. Generally, such systems consist of pipes, nodes , pumps, valves, storage tanks and reservoirs. You are able to track the flow, the pressure, the height of the water in each tank, as well as determine the chemical concentration and the age during a simulation period.
