Project for


is focused on water treatment in

places where there isn’t an adequate or available public

water supply. The location chosen as a pilot area for the

project lies in the Triglav National Park, where, contrary

to public belief, spring waters are quite contaminated.

Most problems lead to groundwater, which represents more than

90 % of drinkable water in Slovenia. Big cities have outdated

water systems, which are still regulated and regularly monitored.

But it’s estimated that 20 % of people aren’t connected to the

public water supply and live around areas where agriculture is

practiced intensively and is not regulated quite often.

Farming is a major contributor to water contamination.

Fertilizers used in crop production seep into the soil and from

there into the water where E. coli bacteria grows and


As such their drinking water is not monitored and often contains

bacteria E. coli. That problem can be seen even in rural parts of

Slovenia such as Triglav National Park. In spring and summer

time people have to boil their water, so that they do not get

infected with the E. coli when they drink tap water.

E. coli is a type of coliform bacteria, found in soil, plants and

water. If E. coli is transmitted to humans it can cause diarrhea,

vomiting, cramps, nausea, fatigue and sometimes even death.

The project is focused around natural and vernacular water

cleaning systems. Slovenia belongs to the most forested

countries in Europe. Researchers found that xylem tissue from a

white pine tree, when used to filter contaminated water, removed

99,9 % of E. coli bacteria.

Ceramic water filters are an inexpensive and effective type of

water filter that rely on the small pore size of ceramic material to

filter dirt, debris, and bacteria out of water. This makes them ideal

for use in developing countries, and portable ceramic filters are

commonly used in backpacking.

The filter offers an affordable solution by combining vernacular

contemporary production processes.

The installation of intricately shaped filtration modules purifies

water of contaminants as small as bacteria, leaving behind

desired constituents such as minerals. It’s made of clay mixed

Filter in the water and filtration.

Our aim is to develop a modular system constructed from 2-3

similar geometric elements that together build a larger prototype

that works as one, depending on the scale of the site, or volume

of water to be treated.

... But how does

really look like?
