With the introduction of corrugated iron in the 19th century, Australia became a willing recipient of vast amounts of corrugated iron predominantly as a housing material. It was shaped or curved by machine for use in tanks or bullnose verandas.
There were concerns about water quality and safety in the 1950s - 60s in Orange. Council encouraged people to remove tanks and rely on the reticulated water supply. Some residents resisted, like Dr Hoddie who swore by the purity and flavour of his tank water until the tank was checked and a dead possum was found floating.
With the severity of recent droughts and government initiatives for user-pays water, tanks are regaining popularity as an alternative source of water and as a water conservation measure.
