Discreet and easy to use, the Rainwater HOG was designed by award-winning Australian designer Sally Dominguez. Dominguez wanted to find a low profile and horizontal rainwater tank to use under decks and patios in urban properties. She was told that a flat, plastic tank simply would not work. Her solution? To prove the naysayers wrong. Her creation uses the continuous walls of a center hole to brace the wide plastic box. This new concept in rainwater storage is now used by multiple manufacturers. The 50-gallon tank is made of FDA & HPB compliant food grade plastics and 100% recyclable materials in the USA. It can be used to store rainwater for horizontal and vertical use, has fittings that make it easy to connect to other HOG tanks, and weighs only 40 pounds when empty.
