With Australian house blocks getting smaller, rainwater tanks can be left out due to the space they require. Designed in mid-2020, the Australian designed and manufactured 4000L ThinTank is the rainwater tank which can fit almost anywhere at only 75cm wide; making it the thinnest 4000L tank available in the Australian market. Constructed to look like a fence, it can seamlessly blend into the backyard, be hidden away down the side of the house, be transformed into a unique Vertical Garden System with ThinPots or be linked together to create extra capacity as well as form walls and fences.
