EPANET is a dynamic water distribution system simulation model released by the United States Environmental Protection Agency for both utilities and consultants. It uses the standard node-link relationship common throughout most engineering programs. EPANET was highly received in the market because it was distributed freely, and has what is even today considered to be the industry standard computational engine. It removed the cumbersome Hardy-Cross procedure from models and introduced what is termed "The Hybrid-Gradient Algorithm" that takes the network and writes it into a series of linear equations. EPANET can be used for all kinds of drinking water modeling: Flows in pipes, Pressures at junctions, propagation of a contaminant, chlorine concentration, water age, and even alternative scenario analysis. It can also simulate spatially and temporally varying water demand.

Today in engineering, EPANET is not still as commonly used as it once was because many software companies have developed more powerful, proprietary packages, often GIS-centric. However, EPANET is considered to be the native format of the models so it acts as the translator to go from one software package to another and as a result will probably always be around.

Currently, there are compatibility issues with Windows Vista and this program. Some modeling software built on this package include: Info-Water by MWHsoft, MikeNet by DHI, and WaterGEMS from Bentley Systems, Inc.
