The Malaysian education system is much more than an academic factory; it is a microcosm of the country itself. Through the shared experiences of early morning assemblies, canteen breaks, and multicultural festival celebrations, school life in Malaysia builds a unique sense of national identity. It equips students not only with the academic tools required for the global economy but also with the cross-cultural empathy necessary to thrive in a diverse society.

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.
