Putting forward the idea of piping water from Tas to Vic....

The trouble with grand water schemes is that the people who finance the project want their money back, and then some. So companies who buy water rights will insist the right to charge what they like, ban local users accessing the water that used to be theirs, insist end users use their water only, and demand the right to walk away as soon as the environment can no longer support the water extraction, and be compensated for it. No water project, including the new SA desal plant, happens without contracts to guarantee profits for the developers. Don't need the water? Tough, you are still paying through the nose for it.

The huge energy to pump water across Bass Straight would come from where? Gigawatts of hydroelectricity probably, and coal power when you run out of water power.

Far better to stop wasting clean water on processes that don't need it. How many percent of total water supply comes into direct contact with humans? Not much, I imagine. Reducing wastage and storing local runoff is a much more useful method of making water available to those who need it.

This is simply not true. The energy requirement is not great. See my post above re the Kalgoorlie pipeline.

Fair enough, a pipeline engineer is needed to give real numbers to this question. However I think the down hill part of the deal would be far less than the friction losses over how many km? Too lazy to get out the atlas.

The Kalgoorlie pipeline is a classic example of engineering might, benefitting the miners and the WA economy in large amounts. The flip side is that the original pipeline had steam powered pumping stations along it. This led to massive clearing of timber and the associated problems with rising dryland salinity. These costs weren't applied to the original pipeline and will cost mega dollars in lost acricultural production.

Simply without a full public analysis of cost and benefit no such scheme should go ahead, especially not in the hands of private developers.

For a better understanding of Australia's pipe dreams, you should read "The Water Dreamers, the remarkable history of our dry continent" by Michael Cathcart. I borrowed a copy from my local library, it was very interesting!

You really need to watch the videos.... most of the questions are answered

Costs... Yield...environment....etc

Btw.. Victoria is building a desalination plant ...Cost $4.9 Billion ..water bills are expected to double over the next five years to pay for it

Update: Sorry that's already blown out to $5.6 Billion and it still in its infancy...

From Tassie to Melbourne ~ 350 kms, and the water source is significantly higher that the destination.

From Perth to Kalgoorlie ~ 650 km and the water source is 300 metres lower than the destination.

I acknowledge the problems of the past WRT the Kalgoorlie pipeline. But they aren't there today. Efficient electric pumps now pump the water. That pipeline has repaid the investment many many times. It gives life to the city of Kalgoorlie-Boulder and many other towns along the way.

Given the shorter distance, plus the elevation of the source over the destination, this should be easy - especially with more than a century of technological development since then!

cheers

ps
Its bad enough vic steals our envoirment friendly hydro power

Of course there is nothing that people on the AUSTRALIAN island of tasmania, could ever be using from the AUSTRALIAN mainland. :D:D
