Watreo / Efficient Water Design


Want to mindlessly stay in the hot shower while being guilt free? Watreo is the answer. Watreo allows users to reuse the water that has been used to rinse the body once. Watreo uses a container that collects some of the water and this can be chosen to be drained or be reused by the user. The electricity demands of the product is not too high as it uses a water mill positioned directly below the shower head to generate the needed energy to pump the reused water. Watreo allows users to reuse water in a radical way which should reduce the water demands of households which use it.
