Four Turkish university students have developed Washit, a shower unit that collects and filters used water for washing clothes or showering. Ahmet Burak Aktas, Adem Onalan, Salih Berk Ilhan and Burak Soylemez first started Washit as a university assignment, but they recently brought their project to a whole new level, winning the iF Concept Design Award 2012: Hansgrohe Special Award for their water-saving design.
Washit uses a closed plumbing system with two water pumps, three filters (carbon, organic and chemical), a UV cleaning phase, a heater and a water storage unit. While the user is having a shower, Washit gathers grey water from the bottom of the shower, passes it through the filters and UV unit, and sends the water to the storage unit. This stored water can then be used for further showering or washing clothes.
The team was inspired by the issue of excessive water use in the bathroom. They looked for a solution that “would fit to users’ life easily without limiting anything about showering, which is a relaxing, calm and pure activity.” From this came the idea of joining a shower and a washing machine.
Following the win, the students started the prototyping phase and are now working on various solutions with the help of their university tutors.
