Rainwater HOG : Product Range:
The Rainwater HOG tank was designed by award-winning Australian designer and architectural practitioner Sally Dominguez. Originally seeking to design a low profile horizontal tank for use under decks and patios at inner-city properties where space was at a premium, Sally was told by tank salespeople that a “flat’ plastic tank would not work — and she set out to prove them wrong. Using the continuous walls of a center hole to brace a wide plastic box was a new concept in rainwater storage which has now been adopted by many other tank designers. Once Sally had designed a working horizontal tank she was determined to make the HOG as useful as possible — so she re-engineered it with several smaller bracing through-holes to create a narrow, space-saving module which could hold and conduit water in any direction without causing pooling or ponding. HOG was named when rainwater was still considered “grey” water — hence the name H2O Grey or H2OG.
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 ½ 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.

Materials
The Rainwater HOG modular tank is rotomolded in virgin polyethylene which complies with AS2070. The HOG is molded of food grade plastic which complies with FDA and HPB regulatory standards for food contact. However, Australian and USA law state that rainwater should not be used for drinking water. The water from your roof can be contaminated with animal and vegetable matter which needs to be filtered from stored water before it is fit for consumption. The fact that off grid communities and rural areas do use rainwater for drinking purposes demonstrates that it is possible if the right collection and filtration measures are taken. Generally in suburban and urban areas it is not permitted to harvest rainwater for drinking or other potable use apart from toilet flush and laundry wash. The tank material itself is 100 % recyclable and has been designed to last you a lifetime.
Size
Each Rainwater HOG tank manufactured in Australia has a capacity of 180 liters, and the following dimensions: 500mm x 220mm x 1800mm. The HOG weighs approximately 18 kg when empty and 200 kg when full.
Each Rainwater HOG tank manufactured in the US has a capacity of 51 gallons and the following dimensions: 20” x 9.5” x 71”. The HOG weighs approximately 40 lbs when empty and 440 lbs when full.
Colors
The Rainwater HOG is currently available in the standard tank color of Bronze Olive Green, but can be produced in almost any other color for orders of 20 or more units. To name a few exciting color options, we have produced red, orange, black, white, and lime green HOGs. Please be advised that we do not paint the HOGs to make them different colors — the Rainwater HOG is manufactured by our factory in the chosen color.
Mix ‘n’ Match
The Rainwater HOG is designed to work with conventional connection components which are individually guaranteed by the manufacturers. But since our connection points are a brass 1 “ NPT /24mm thread, you can work with our suggested parts — or simply buy your own. Go to The Accessories page for more information.
