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.


If you’d like, I can: (a) list the most commonly used DIN VDE 0100 parts and what each covers, or (b) provide a short template email to request an official English translation from a standards vendor. Which would you prefer?
DIN VDE 0100 is Germany’s foundational standard series for electrical installations in buildings. It aligns national safety, design, and verification practices with broader European norms (notably HD 60364) while reflecting Germany’s regulatory, technical, and market context. Searching for an “DIN VDE 0100 English PDF” is a common need: engineers, contractors, inspectors, educators, and international firms want to read and apply these rules in English. Below I discuss what the standard covers, why an English version matters, practical limitations around obtaining authoritative PDFs, and how readers should approach using translated standards in practice.
No setup or downloads — just instant access right in your browser.
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.
