Think about the amount of unused water wasted while you wait for it to warm up. For perspective… between all of us who shower, we could save up to a whopping 2 trillion liters per year. WaterDrop is a system by the designers at Esferic that helps do this by catching the otherwise wasted water for use in other areas. It attaches to the existing shower head or fauce and catches the water which can then be used for a variety of domestic purposes such as filling buckets for mopping, watering plants, flushing toilets and more. It’s made of thermoplastic polyurethane, so it’s as durable and strong as possible as well as 100% recyclable! (Source: Yankodesign.com ) For more information just pay a visit at the link below.
