Water – Designing a Biovernacular

This project, with its final result being an extra efficient water filter, is focused on water treatment in places where there isn’t an adequate or available public water supply. Around 20% of Slovenes are not connected to the public supply, and even those who are often prefer to use water which they collect from other, natural, sources. There is a common belief that spring water in Slovenia is clean, but since a large part of Slovenia lies on karst grounds, it is difficult to predict the flow of groundwater and the accompanying pollution.

A short insight into the xylem filter and ceramic filter making processes, a sample analysis of water contaminated with E. coli, a 3D model drawing and 3D printing of clay.

Pjorkkala – the team mentored by Shneel Malik, an architect, biodesign researcher and social entrepreneur – is addressing the problem of pollution in natural water sources in Slovenia by creating prototypes for local, nature-based solutions. 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.

The filter, named Dodola after the Slavic goddess of rain, offers an affordable solution by combining vernacular materials and practices, natural and physical phenomena and 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 with organic material and fired in a way which increases its porosity. The gyroid structure which accelerates the filtration of water by increasing the available surface area of the module is achieved by 3D printing. Following principles inspired by the Archimedes’ screw, Dodola moves water through the filter by relying on the flow of the water it is placed in, meaning it can work in remote locations where electricity isn’t available.
