The EPANET user's dilemma

  • Classic EPANET is powerful — but clunky and outdated. Workarounds become your workflow — slow and cumbersome.
  • Big-name platforms look polished, but they're overpriced and bloated with features you don't need to analyze your network quickly.
  • Modern browser-based tools exist — but they force your data into the cloud, raising privacy and compliance concerns. Plus, they offer little for those doing long-term planning and analysis.

You shouldn't have to choose between speed, security, and affordability just to understand your water networks.

Today, if you visit Adobe’s official site, Flash is a ghost. They killed it with extreme prejudice in 2020. But version 11.5.0 existed before the "kill switch" telemetry was fully baked in. By downloading the (the standalone .exe or .dmg ), you bypass the need for Adobe’s dead activation servers.

Have a specific old game or animation you are trying to run? Let me know in the comments—I might still have the projector file saved on a dusty external drive.

It is the sound of a 56k modem handshake, the sight of a pre-loader spinning in a circle, and the feeling of clicking a "Play" button on a game that your high school self stayed up until 2 AM to beat.

EPANET deserves better — and so do you.

EPANET was a gift to the industry — free, open-source water modeling for all. But commercial vendors built on it, locked away improvements, and left the community behind.

epanet-js is our answer: a faster, simpler, affordable water modeling tool that protects your privacy and sustains the open-source future of water modeling.

We're proud to be part of the next chapter — and we're just getting started.
