Short Description

Dodola's a ceramic water filter for places where the public water supply isn’t adequate or available

Detailed Description

The product Dodola is an installation of intricately shaped filtration modules which purifies water of contaminants as small as bacteria, thereby leaving behind only the desired constituents such as minerals. It’s made of clay, mixed with organic material and fired in a way which increases its porosity by a manyfold. The gyroid structure which accelerates the filtration of water by increasing the available surface area of the module is achieved by 3D printing the otherwise fragile raw clay mixture. Through the incorporation of the principles inspired by an Archimedes screw the product can transport the filtered water upwards by relying on the flow of the water it is placed in, meaning it can work in remote locations where electricity isn’t available.

Project Details

Does your design take social and cultural challenges and human wellbeing into consideration?

Dodolas are designed for areas that the public water supply doesn’t reach effectively. Since they are susceptible to political, economical and environmental disturbances, people can’t always rely on centralized solutions when it comes down to basic needs, therefore alternatives to these systems are crucial for resilience. This communally managed and owned system we designed can empower communities and make them more resilient and self-sufficient.
The system is tailored to people’s needs and habits instead of relying on people changing their way of life to enable the design.

Does your design support sustainable production, embodying circular or regenerative design practices?

All materials used are sustainable, natural and locally found. The clay can be collected in nearby forests and the saw dust is obtained from local woodworkers. The 3D clay printing technology doesn’t create any material waste during the production. The final product needs very little maintenance and no additional parts. Furthermore it is autonomous and doesn’t need electricity to function.

Does your design use principles of distribution and open source?

All of the software used for production of the Dodola (Blender, Cura) are available to the public. Principles used for designing Dodola were all taken from already widely known knowledge and practices and were integrated into the final solution. The whole process and research findings are shared with the public at the exhibition and online platforms. But most importantly Dodola is a solution which could be shared to various countries by being open-source and could be produced locally.

Does your design promote awareness of responsible design and consumption?

Dodola is a product where design had the most important role, it was used to offer an alternative to already existing ceramic water filters which aren’t either sustainable or viable in terms of effectiveness. It was also used to develop a product which would be long lasting, efficient and would promote decentralized and radically sustainable solutions.
At the same time the purpose of the project isn’t only to offer a sustainable water filter but also to encourage users and all other stakeholders to be aware of the problems connected to water, not just in areas where this is already well known but also in areas which are contaminated contrary to belief in purity of the water that is available there.
