Hungarian firm Ivanka wants you to be able to easily & safely drink your rainwater. Rainhouse is a project where falling rain is redirected through a series of filters, starting with a patented material called “bioconcrete” on the roof. Specially-designed stainless steel pipes filter out more contaminants before the water lands in a cistern. The concrete can be applied to current structures as well as new ones.
