Water tanks would cost nearly 200 times more…
Jon Faine, spruiking Green policies on the ABC yet again this week, promotes the mandating of rain tanks for Melburnians. This desire of his underlines the economic and mathematical illiteracy of the Left. They can’t do sums, and have no idea of real costs to real people, most of whom can simply not afford the luxuries they indulge in themselves.
From my reckoning [figures from official government websites]:
The average total cost of a 5,000 litre tank is around $3,137.
For a Melbourne population of 4,644,950, there are 1,667,687 households. Therefore, the total price for mandating rain tanks would be approximately $5 billion and they would store a potential 8,330 ML of water.
The dam that Labor has refused to build, the Mitchell Dam, would have had a capacity of 500,000 ML. That is, one dam, costing around $1.5 billion — that is a third of the cost of rain tanks and equivalent to just three years of operation of the $5 billion desal plant — would have stored 62 times more water. This is, dollar for dollar, nearly 200 times more water for the money spent. Or to put it another way, Faine’s planned mandated water tanks, if they were to do what this one dam could do for $1.5 billion, would cost individuals the equivalent of $180 billion.
In addition, the proposed mandated rain water tanks would, in a drought, last an average household — at 155 litres per person — only two or three weeks. The one extra dam would supply water to Melbourne, at the same rate — for around two years.
Maybe households in Fitzroy can afford this nonsense but it would either hurt the poor, or if subsidized, overwhelm the taxpayer. Either way, it is crazy economics and utterly stupid as a way of waterproofing a city like Melbourne. But do the fanatical greens care at all ?
