With the help of Triglav National Park administration we found out

that local users collect water from the naturally occuring springs

because they believe that water is healthier than tap water. In

order to enable that behavior we wish to offer filtration systems by

developing a prototype based on ceramic filtration.

The final product Dodola is an installation of

intricately shaped filtration modules which purifies

water of contaminants as small as bacteria.

Dodola is multitude more efficient than already

available ceramic filters, because of the used

technologies and principles such as gyroid

structure and archimedes screw. The filtration

system is self-operating and doesn’t need constant

Dodola is a pagan tradition found in the Balkans, South Slavs

used to organise the Dodola / Perperuna festival in times of

drought, where they worshipped the goddess named Dodola

and prayed to her for rain.

The objects are mostly submerged underwater where porous

structure filters water as it passes through the material. Because

of the rivers flow the objects rotate, and by doing so transport the

water towards the upper part of the module, where it leaves the

system to be used as potable water.

To increase the permeability of water, the filter was

designed by incorporation of the gyroid minimal

surface, which can be observed in beetle shells and

paths of butterfly’s wings mid flight.

The structure used in the water filter increases the

area of water permeability by a manyfold, which

consequently accelerates the water filtration.

Furthermore using this structure makes the objects

statically reinforced.

We use the flow of the river to turn the filter with an archimedes

screw, which then transfers the water from lower to higher plane.

By using the flow of water to power the rotation of the filter the

object can be installed even in remote areas where there are no

power connections.

Water travels up.
