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  • Classic EPANET is powerful — but clunky and outdated.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.

Mind Under Master Harmony [VERIFIED]

Harmony is the natural state that emerges when the mind willingly serves the master. It is a state of balance, inner peace, and alignment. As Osho beautifully puts it, "Harmony is happiness, and harmony is heaven. And harmony happens only when you are in tune with the whole". When you are in this state, your thoughts, feelings, and actions are no longer fragmented. There is a sense of effortlessness, a "spontaneous flow and expression of joy and harmony".

Even with practice, the mind will revolt. It is old and stubborn. Here is how to handle the rebellion.

Achieving this state is not a permanent destination; it is a daily tuning. A violin left in its case goes out of tune. So too does the mind. Here are three rituals to restore "Mind Under Master Harmony" every day.

When you install a Master of Harmony—be it your Higher Self, your Conscience, or simply the Law of Presence—you are not losing liberty. You are trading the chaotic slavery of the reactive mind for the dignified freedom of the responsive mind.

Overthinking stops. The master analyzes the facts, makes a choice, and moves forward without regret. Overcoming Common Roadblocks The path to mental harmony faces predictable challenges.

Your breath is the remote control to your nervous system. When you feel your mind starting to descend into noise and discord, take slow, deep diaphragmatic breaths. Inhaling for a count of four, holding for four, and exhaling for four can instantly bring a sense of calm and order back to your brain. Step 4: Curate Your Mental Input

"Mind under master harmony" is the ultimate goal of mental wellness. It is the realization that while we cannot always control the events of our lives, we can always choose how we respond to them. By cultivating awareness, kindness toward ourselves, and taking deliberate pauses, we can turn a chaotic mind into a peaceful, disciplined instrument for a better life.

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.

Co-founder

You may not know this, but for decades, the U.S. EPA has given the water industry an extraordinary gift: the free and open-source hydraulic modeling software EPANET. Odds are, if you've used any commercial hydraulic modeling software today, it was built on the EPANET engine.

The problem is, instead of giving back to their open-source roots like other industries do, big-name software vendors took EPANET's open code, built private tools on top of the engine, and then locked those improvements behind patents and proprietary licenses.

Some vendors even pressured the EPA to focus only on the engine — discouraging any effort to improve the interface or user experience for everyone else.

Those vendors now charge you exorbitant prices to use their software while EPANET lags behind — and utilities, engineers, and educators with smaller budgets suffer.

We think this is backwards — and we're on a mission to change it. We're focused on creating a better experience for the entire hydraulic modeling community.

That's why we built epanet-js under an FSL license — because we want to give you an affordable, easy-to-use water modeling option that creates a sustainable future for open-source EPANET development.

Support EPANET by using software that supports it back.

A better future for water modeling.

Simple, quick, and useful right out of the gate — designed to open-and-go.
