  • 1.1 What is EPANET 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.
  • # Description This repository was established to provide U.S. EPA's official release of 2.2.0. The last official release of EPANET was version 2.00.12, dated 2008. The release of EPANET 2.2.0 represents a significant step forward in two important ways.

Description:

EPANET is a Windows program that performs extended period simulation of hydraulic and water-quality behavior within pressurized pipe networks. A network can consist 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 provides a fully equipped, extended period hydraulic analysis package, which can:

  • Handle systems of any size
  • Compute friction head loss using either Hazen-Williams, Darcy-Weisbach, or Chezy-Manning equations
  • Include minor head losses for bends, fittings, etc.
  • Model constant or variable speed pumps
  • Compute pumping energy and cost
  • Model various types of valves including shutoff, check, pressure regulating, and flow control valves
  • Allow storage tanks to have any shape (i.e., diameter can vary with height)
  • Consider multiple demand categories at nodes, each with its own pattern of time variation
  • Model pressure-dependent flow issuing from emitters (sprinkler heads)
  • Base system operation on simple tank level or timer controls as well as on complex rule-based controls.

In addition , EPANET's water quality analyzer can:
  • Model the movement of a non-reactive tracer material through the network over time
  • Model the movement and fate of a reactive material as it grows (e.g., a disinfection by-product) or decays (e.g., chlorine residual) with time
  • Model the age of water throughout a network
  • Track the percent of flow from a given node reaching all other nodes over time
  • Model reactions both in the bulk flow and at the pipe wall
  • Allow growth or decay reactions to proceed up to a limiting concentration
  • Employ global reaction rate coefficients that can be modified on a pipe-by-pipe basis
  • Allow for time-varying concentration or mass inputs at any location in the network
  • Model storage tanks as being either complete mix, plug flow, or two-compartment reactors.
EPANET's Windows user interface provides a visual network editor that simplifies the process of building piping network models and editing their properties. Various data reporting and visualization tools are used to assist in interpreting the results of a network analysis. These include graphical views (time series plots, profile plots, contour plots, etc.), tabular views, and special reports (energy usage, reaction, and calibration reports).

EPANET was specifically developed to help water utilities maintain and improve the quality of water delivered to consumers through their distribution systems. It can be used to design sampling programs, study disinfectant loss and by-product formation, and conduct consumer exposure assessments. It can assist in evaluating alternative strategies for improving water quality such as altering source utilization within multi-source systems, modifying pumping and tank filling/emptying schedules to reduce water age, utilizing booster disinfection stations at key locations to maintain target residuals, and planning a cost-effective program of targeted pipe cleaning and replacement.
