Introduction
Global water issues

Water is essential
Water is the foundation of life.
It is 70% of our body and the basisof our daily life, industry, and otheractivities.

Water problem in Africa

Severe waterfetching
their children'seducation deprived.

water-stressedregionMore than 400 million
people suffer

Dirty water
Unsanitary andcontagious diseases
can be deadly.

Oasis of tree
1/4 people suﬀer from watershortage.
An idea that may provide a solution
to this problem.
It is the Warka Water Tower.

Evolution of Warka Water

Is the amount of watercollected related to thechange in version?

Hypothesis = "Wide" has a higher
water catchment.
Lowness

V4.1
V4.2

Water vapor ﬂows
downward

Latest version

Match the climate
Is it hard for the wind
to blow?

Increased watercollectionReferenced Studies
Water collection is possible
with smaller models
Water does not
fall into the tank.

Referenced Studies
Collecting water fromsteam is possible

Focus on fog

Conclusion
Version Evolution
・Evolution has nothing to
do with water catchment.
・Water catchment-✕
Convenience-○

Water collection correlateswith dry volume「Density」「Rotundity」「Lowness」「water collection○」⇔「water holding○」

Comprehensiveness Wide
・Wide, with excellent functionality
・Easy to build and collapse-resistant

What we think is best
・Focus on Comprehensiveness・Improved v4.1. Dead space canbe collected by utilizing theinterior.
