Epanet 2
EPANET is a Windows 95/98/NT 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.
The Windows version of 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. These include color-coded network maps, data tables, time series graphs, and contour plots.
EPANET was developed by the Water Supply and Water Resources Division (formerly the Drinking Water Research Division) of the U.S. Environmental Protection Agency’s National Risk Management Research Laboratory. It is public domain software that may be freely copied and distributed.
EPANET capabilities:
- handle systems of any size
- compute friction head loss using the Hazen-Williams, Darcy-Weisbach, or Chezy-Manning formulas
- 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
- 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).
i am very happy that nation like usa think to educate all this world espesialy in hydraulic
and i have all respect to brain of this country to think and elaborat logiciel of simulation and think to destiny of water in pipe
i am ferdia aek engenner from algeria
bonjour .merci pour ce logiciel .
et je te dit que ce ci ils ya des ereur ou des remarque.
merci
i want to get the software
could i down load it?
requesting for free trail package for practice and understanding about to working and uses in infrastructure projects as we are the beginners .
See download link above.
I would like to download this software,it is very important for my job. thanks
please i want to download EPANET software ,because it’s will help me to integrate more notions in hydraulics
thank you and i am waiting for your answer.
I would like to download EPAnet software for new version, because it can help my job. I am waiting for your answer. thanks
Dear
I am download the program, so iam looking for examples for perform this prg.
I would like to download epanet software
I WOULD LIKE TO DOWNLOAD EPANET SOFTWARE. IT WILL BE VERY USEFULL
I WANT TO DOWNLOAD THE EPANET SOFTWARE. THIS SOFTWARE WILL HELP ME IN MY COMPANY JOB FOR DESIGNING OF NETWORK OF PIPELINE IN FIELDS.
go to the bottom of this website.

Its very simple.
i am an engineer whose main exposure is the design, construction and management of water systems in the philippines. i would like to request for the download of the epanet software to make the quality of our output and practices be upgraded with your internationally admired standards.
Bong – you may download EPANet from the link at the end of the post.
I WOULD LIKE TO DOWNLOAD EPANET SOFTWARE. IT WILL BE VERY USEFULL
Thankyou very much.
Please permit me to download the Epanet 2.
Thanks.
Please my i download Epanet 2 for trial
Your software is very good and easy to use
I need a free download of EPANET.
can i have a copy of this programm?
Merci!!!
i want to ge the software
Hello
I’m still a novice on EPANET but I got a problem on the projection system. I wish spend EPANET to EPANET Z without problem. But this is not the case ! Under EPANET, the projection system is the Lambert 2 and under EPANET Z need WGS84. I try to transfer the file .net in .shp with epa2GIS, then to re-project, but it created 5 files .shp. I canג€™t perform the opposite operation shp2epa. Have you any idea?
Thank you in advance!
greetings
I need EPANET free
Tanks
Greetings
Please Send EPANET software free.
thanks
Bonjour,
svp je cherche code matlab que epanet utilise pour calculer l evolution de la concentration de chlore sur les noeuds dans le reseau Net2,vous savez pas ou je px le trouver?
c est trֳ©s interessante pour moi d avoir une repense de votre part merci infiniment d avance 🙂
how can I integrat Matlab with EPANET?
Matlab and EPANet:
http://www.water-simulation.com/wsp/2009/05/06/epanet-and-matlab/
I WOLUD LIKE DOWNLOAD THIS PROGRAM.
Can you give me the Darcy-Weisbach friction factor for plastic pipe? In the programm it is listed as “millifeet” but I suspect it is different for metric/US units? From my textbooks it looks like the friction factor is .005 mm, would like your input.
thanks
Hi,
I am looking for realistic water distribution network topologies and demands in EPANET format. I’d appreciate any pointers to the same. Thanks much.
Arun
Arun,
Look at the BWSN networks:
http://www.water-simulation.com/wsp/about/bwsn/
Thanks a lot, Elad. I’ll look into those.
Elad,
I looked at the BWSN link you had suggested, but couldn’t find the inp files along with your utilities. I also looked at the WDS conference website for BWSN, there is a “rules” document in pdf which states that only the approved participants will be emailed the network models. Sorry if I have missed something obvious, but could you possibly help me with the inp files. Thanks again.
Arun
Arun,
I added the networks to the BWSN page.
Here is a direct link.
Got them. Thanks again, Elad.
Please Send EPANET software free.
thanks
I am using water cad soft ware in designing of watersupply distribution network in my company. It is requested that Please Send EPANET software free so that i can check the differanace between the two.
thanks
Download EPANet from here:

im a civil engg. student my project is on design of water distribution network. i use EPANET to design WDS. so please give me some guidlines .
i want to check some ws system designed long time ago facing increase demand. Pls assist me with a free copy of EPANET software.

I wish very much to have this program to help my job
In fact I am still getting dificult to solve the epanet 2. Can you send me some help about the problem? I mean the node.
i wish to learn EPANET 2 s/w for this i need free tutorials. if any one have these pls kindly fwd to my email id
o epanet é um programa de computador que serve para executar cimulações dinamicas e estaticas, do conportamento hidraulico.
Gostaria de saber mas com relação oa epant
será que podem me fornecer o softwer do programa epanet? é munto importante para mim.
