epanet-js
No installs. No forced cloud storage. Just fast, local-first water modeling — powered by the engine you already trust.
You shouldn't have to choose between speed, security, and affordability just to understand your water networks.


Pay the €30 for a legitimate digital copy, or rely on community forums. The hour you spend disinfecting your computer from a fake "free" manual is an hour you could have spent actually fixing your C2’s leaking rear axle joint.
After all, you bought a Citroën – you knew the ride would be complicated. The manual shouldn’t be.
In the vast ecosystem of French automotive enthusiasts, few models inspire the same bittersweet nostalgia as the Citroën C2. Produced between 2003 and 2009, this quirky, asymmetric-hatchback became a cult classic. Yet, two decades later, owners are scouring the darkest corners of the internet for a specific digital Holy Grail: "Revue Technique Citroen C2 Pdf Gratuit."
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.

When you purchase more features in epanet-js, you're investing in the future of open-source EPANET development.
Our open-source model balances innovation and accessibility:
Anyone can build on our code. The two-year commercial-use delay gives us the incentive to keep pushing forward — and that fuels progress for everyone.
That means when you support us, you support more affordable hydraulic modeling software for the entire community.
