The future of water is the future of mankind.

WOTA will change how we perceive water.

The history of mankind is the history of water.
Humanity has sought for water, for all of its history.
WOTA will free everyone from the constraints of water.
A future where everyone, everywhere can access water freely.

We believe, that once we are liberated from our greatest constraint; the constraint of water, our lives will become more free and creative and full of excitement.

Cities will change, and people will start living in deserts, small islands, and even outer space.

But for that to happen, we must achieve a smaller water cycle that every person can own.
Humans have been dependant on large water cycles.
WOTA will liberate humanity from the constraints of water, by realizing a small water cycle.

WOTA will make great efforts to provide a better life for humanity.


Water freedom
for everyone, everywhere

We will create a future free of water related problems. A future where the freedom of water is not constrained by money, age, or nationality.
