HOG tank fits into spaces where other tanks do not, and its compact size allows it to be easily retrofitted and then connected up once in situ for larger volumes of rainwater storage in tight spaces along side passages, below houses, and under decks. Not only was the HOG sized to fit between joists spaced at 600mm (24 inch) centers, but it was also sized for maximum thickness (9 inches/220mm) while also keeping useful thermal mass characteristics. Any thicker and the thermal benefit would be impaired, any thinner and the capacity would be inconsequential. The tank will support its full weight on any of its surfaces without bulging, which allows it to be installed either horizontally or vertically for rainwater capture. Not other water tank is designed to be so versatile.

 

Optional accessories include a Wall Kit (to attach the HOGs to a wall) and an Inlet Outlet Kit (to stop debris from the roof getting into the tank and to allow easy access to the water from the HOGs)
