Also note in Holland they too pump out the excess water....
Essentially this is not a new idea. Would it work in Sydney, well probably, but building a recycling plant is far simpler, far more effective, and doesnt destroy the local ecosystem...

Thanks for posting that advice Michael
it is encouraging to hear the Dutch see value in the approach as they are rather water sensitive
. Their famous myth about the fella putting his finger in the sea wall says a little I recon.
.
I love hearing that my crazy ideas are not so crazy
( I have a lot of ideas and as people get sick of them I call them crazy to save them thinking of a term to describe them
) AND being presented with information that someone has tried it and done it and it has worked for them it offers me support to follow up on other crazy ideas
. If I love the NET for if anything it is for being able to post an idea and to find that it has been done
. Does not give me anything but joy
.. good on them they made a buck whatever
. it leaves me free to work on new ideas, having sortta cleaned out the accumulated mess. As well as every other problem I see in myself I am sometimes lazy and don’t want to waste time just in the interest of proving something, so it good to find such things.
If China and Holland can do it and have chosen that path maybe we should at least have a committee to look into the matter. One place has water management problems and one has that problem and water supply problems.. just maybe we could look into it as a possible alternative. There is has been a dramatic effect by newer humans on Australia but we have been changing this place just a little for 200yrs I recon, so maybe a little more changing to get it just right would be OK. AND I don’t know that nuclear power plants and desalinates are really pretty to look at
.. I bet I could make a beautiful underwater dam but how could you make a desalination plant and a nuclear power station look desirable. That dam in China is a tourist attraction it is nothing short of beautiful
..but I don’t know how the Netherlands did theirs
.
I would like to know the cost of a litre of desalinated water compared to the cost of a litre of stored fresh water
. One offers an advantage that the cost will go down rather than to go up as will there other over time
. Without the math I could not but put forward a ruff outline of possibilities before giving a solid comment on which will prove to be the most efficient method. As a simple unsupported statement I think that with a dam the cost of your water supply would go down over time as the bulk of the cost is in the building stage. with nuclear power and desalinates we have the building cost and the cost of fuel which as time goes on and supply diminishes the cheap fuel will become more expensive and as such so will the cost of the water. Petrol was a cheap way to go at the time but in time it will run out as that day draws closer the price will go up. Nuclear fuel is finite and the prospect of fission is maybe never going to happen but to make it happen will take time and money. Some one said 20 years ago we were 20 years away today we say the same ..or something sortta like that
.
Thanks again that is welcome news as it offers our dry country more hope of there being alternatives to consider
.
