EPANET
EPANET is software that models water distribution piping systems. EPANET is public domain software that may be freely copied and distributed. It is a Windows 95/98/NT/XP program. EPANET performs extended period simulation of the water movement and quality behavior within pressurized pipe networks.
Pipe networks consist of pipes, nodes (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 the water in each tank,
the type of chemical concentration throughout the network during a simulation period,
water age,
source, and
tracing.
Capabilities
EPANET's Windows user interface provides a visual network editor that simplifies the process of building piping network models and editing their properties and data. EPANET provides an integrated computer environment for editing input data. Various data reporting and visualization tools are used to assist in interpreting the results of a network analysis. These include
color-coded network maps,
data tables,
energy usage,
reaction,
calibration,
time series graphs,
profile plots,
contour plots.
EPANET provides a fully equipped, extended-period hydraulic analysis package that can:
Simulate systems of any size
Compute friction head loss using the Hazen-Williams, the Darcy Weisbach, or the Chezy-Manning formula
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
Account for any shape storage tanks (i.e., surface area can vary with height)
Consider multiple demand categories at nodes, each with its own pattern of time variation
Model pressure-dependent flow issuing from sprinkler heads
Base system operation on simple tank level, timer controls or 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) over 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 complete mix, plug flow, or two-compartment reactors
