Description:
EPANET is a computer program that performs extended period simulation of hydraulic and water quality behavior within pressurized pipe networks. A network consists of pipes, nodes (pipe junctions), pumps, valves and storage tanks or reservoirs. EPANET tracks the flow of water in each pipe, the pressure at each node, the height of water in each tank, and the concentration of a chemical species throughout the network during a simulation period comprised of multiple time steps. In addition to chemical species, water age and source tracing can also be simulated. EPANET is designed to be a research tool for improving our understanding of the movement and fate of drinking water constituents within distribution systems. It can be used for many different kinds of applications in distribution systems analysis. Sampling program design, hydraulic model calibration, chlorine residual analysis, aned consumer exposure assessment are some examples. EPANET can help asssess alternative management strategies for improving water quality throughout a system including: altering source utilization within multiple source systems; altering pumping and tank filling-emptying schedules; use of satellite treatment, such as re-chlorination at storage tanks; targeted pipe cleaning and replacement. Running under Windows, EPANET provides an integrated environment for editing network input data, running hydraulic and water quality simulations, and viewing the results in a variety of formats including color-coded network maps, data tables, time series graphs, and contour plots.
