Water H2OG multidirectional rainwater storage units are back in the hands of inventor Sally Dominguez and her company Hog Works and demand is huge - not only in Australia, but in the USA where green design is big business.
US green designers have discovered H2OG tanks through online sites such as Treehugger and the waterhog site and the tanks feature in Cornell University's House at the Solar Decathlon in Washington this November as well as at West Coast Green in September.
Locally HOG is being specified in a range of domestic and commercial developments from those hard to reach under deck areas for 2000 litre projects to a 20,000 litres plus night cooling system in Victoria.
