EPANET

EPANET is a computer program for the analysis of distribution systems for drinking water. Although in general it can be used for analysis of any non-compressible fluid with pressurized flow.

The program allows hydraulic analysis of pipe networks from the physical characteristics of pipes and dynamics of nodes (consumption) to obtain the pressure and flow in pipes and nodes respectively. Additionally, EPANET allows for the analysis of water quality through which it is possible to determine the travel time of the fluid from the sources (deposits and reservoirs) to the nodes of the system.

Elements that the program can simulate are essentially tubes, nodes, tanks and reservoirs (constant load references) and additionally allows for more complex elements such as pumps and valves.

The original version of the program was developed in English by the EPA and has been translated into Spanish by several institutions. In Spain and Latin America one of the most widely used is that developed by the Polytechnic University of Valencia.
