In the past, original 'Argyle' Victorian heritage houses in Australia used 2,500-litre tanks for vegetable garden watering and flushing toilets. A thorough water study, carried out by S2 design, looked at the water needs of these Argyle houses, and found that a water storage solution, capable of holding enough water for a family of four and a large dog was required.
S2 chose to install maximum rainwater storage in the house’s basement to fulfil the aim of achieving (almost) total water independence from mains water. Kingspan Round Rainwater Tanks could provide the storage solution needed to fulfil these project needs, with 4 made-to-measure water round tanks of 10,850 litres created to fit precisely within the constraints of the tight basement space, supplying almost 45,000 litres of rainwater to the home and garden.
The surface finish of the tanks compliment the original building structure and construction details. However, the water project has received praise not only for its spectacular design but also its social, functional and environmental considerations.
The household's current daily use of mains water has decreased significantly, and currently stands at only around 6 litres per person solely for drinking and cooking. The four Kingspan Rainwater Tanks serve the entirety of the the remaining household water needs throughout the year, estimated at 150,000 litres per annum, plus an additional 30,000 litres supplied for irrigation. Some minor adjustments to the water management systems as a result of testing should ultimately see daily mains water usage in the houses reduced to nil.
