An article in The Boarder Mail reports:

LABOR leader Kevin Rudd wants to put a rainwater tank in every home and has pledged $250 million to get things started.

Mr Rudd yesterday said a federal Labor government would tackle the water crisis by offering up to $500 each to 500,000 homes to help install tanks or grey water piping.

“We want every Australian home and its roof to be a personal water catchment area, maximising reuse and collection of rain water,” he said.

Combined this with State government rebates, this may tip a few people over the edge and get them installing rainwater tanks and greywater systems.
