Modular Water Storage System
"The Waterwall modular system is a rainwater storage solution for urban households. A slim line tank design, each unit is only 330 mm deep and yet holds 1200 litres of water. The beauty of the design lies in the ability to connect any number of tanks together. Not only does this increase storage capacity dramatically, the interconnected tanks can be used as a fence, as a dividing wall in a garden, or fit neatly in a narrow sideway. This gives even a small city yard substantial water storage capabilities."
