EPANET-Z – add online maps and satellite images to EPANET

Update 11/09/2018: for some time now the application does not work due to changes in maps APIs.

EPANet-Z (in free beta) from Zonum Solutions is a modified recompiled version of EPANet that adds the option to insert map and satellite images to the network’s backdrop. The program uses online services like Yahoo maps and Google maps to extract the images. From Zonum’s web site:

The use of a backdrop file brought new capabilities to EPANET. However, how do I create this file? how big this image can be? Is it already georeferenced? How about using an aerial photo or satellite image as a background?

What would you say, if you were told that you could access satellite images for the whole World and use them as a backdrop for EPANET, just by clicking a button?… I would say EPANET-Z.

EPANET 2.00.12 (3/5/08) was modified and re-compiled to display Online Maps/imagery as a background. EPANET-Z = EPANET + Online Maps (Yahoo Maps, Google Maps, Virtual Earth)


I have entered a small part of my neighborhood network to the program. Unfortunately the satellite image in my region is of poor quality (click the image to enlarge):

Update 20/08/2010: for some reason the download link at Zonum Solutions for EPANet-z is broken. You can download it from here.

    This is a great facility that is incorporated . One more request is printing capabilities of the EPAnet has to be oncreased as it allows only the things that are viewable on screen only. So why not we can export the output file to AutoCAD like softwares for proper presentation.

  6. 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!

    Anyone else having problems downloading EPANET Z? There seems to be a problem with the ‘Download Program’ on EPANET Z page of the Zonums site and so attempts to access ‘http://www.zonums.com/software/softdown/softdown_down.php?id=EPANETZ’ result in a ‘Missing ID’ error message.

  10. Yann says:

    Hello, I have the same problem as Will, does anyone have a solution to download it?

  11. Bastian says:

    I have the same problem. Is there another source to download tpanet z?

  12. Bastian says:

    Thank you, download is working now.

  13. Sijbrand says:

    It seems that something went wrong again, sadly, the “missing-id” is back… Is epanet-z still downloadable somewhere else?

  14. nadir says:

    I live in Os, Norway, and have used EPANET for many years modelling and analycing the municipal drinking water distribution system of Os. I was pleased to find this blog about epanet-z, as it seems to be alive in des. 2012. May be I can use epanet-z to improve the backdrops of our epanet model.

    Downloading and installing was OK via the updatetd links on this blog.

    The challenge is to make internet backdrops work with a metric system. Our epanet model is already designed with metric coordinates in this system: http://georepository.com/crs_3044/ETRS89-TM32.html

    Primarily I would like to keep the coordinates of the model and adapt the backdrop. Then changes in the model can still be done without converting anything.
    Another option (less good) can be to convert the model to the coordinates of the backdrop system. Anyway it has to be in metric system.

    I tried to change to metric system in the epanet-z, but the backdrop disappeared imediately.

    Does anyone have a solution to this problem? I guess it would be helpful to all users in Europe.

      Jeg kan lage wmf backdrop til deg i helt nøyaktig målestokk.
      Trenger da digitalt kartverk i sosi, quadri eller shape.
      Si fra hvis du ønsker det.

  18. Nuno Dias says:

    I used this sofware a few times.
    What I have done is change my original metric coordinates in Portuguese Datum to latitude and longitude. You also need to change the units of the coordinates to Degrees.
    I hope this comment is useful.

  27. CS says:

    I’m trying to use EpanteZ but it is not working correctly. I downloaded the zip file and started to work from there but some buttons are missing in the window bellow the browser and some script errors are always showing.
    Besides, when I save the file and reopen, I cannot reach the network using Google maps, only with yahoo…
    Is anyone having these problems too?
    Is there any problem with the zip file?

    Thank you!

    • CS, I have the issues but there is no problem with the ZIP file – it is the one received from the author. Will try to contact him again.

      • Cristina says:

        Thanks Elad. I think this application is very interesting and I really need to use it but, right now, it just doesnt work with google maps…
        If you know any solution for this, please let me know! Thank you in advance!
