Don making up things again.You said it wasn't economic to pump water around (which by necessity you've got to do with recycled water).
At what point did I say you cannot recycle water?
A national water grid is pointless when the cost of moving water around exceeds the cost of simply pumping from the nearest coast line via a desal plant, which is why all these long held "pipe dream" water schemes such as pumping down from Lake Argle have all disappeared in the last 10-20 years.
Desal plants are NOT the answer. Just because they do it in Dubai you think its the answer for the rest of the world. It's hellishly expensive and its putting carbon dioxide into the atmosphere which is apparently some kind of poison (even though its necessary for life).
Of interest, Sth Australia's own desal plant for which Don has been very quiet on was built because of the water taken by others further up stream of the Murry. Also interesting to hear Don not call for more Dam's in SA instead of the desal plant which due to its use has single handily eliminated SA's perpetual water restrictions.Simple. We don't have the capacity for more new dams here like they do in VIC and NSW.
Our desalination plant was operating for the last nine years at ten percent capacity (recently they jacked it up a tiny bit) because it simply isn't needed. It contributes a whole two percent to the overall water needs of Adelaide. It was built at the height of the 'climate change' panic in 2007 along with Wonthaggi but we didn't go for anything like the scale of that plant because someone in charge in this state had the brains to realise a massive one wasn't needed in the longer term. And they were right.
And we never had water restrictions here the same as they did in Victoria - there's pretty much nothing in the above paragraph that you've got right.
But what else is new? You conflate opinion with fact all the time, you don't research anything before you write about it. No wonder I usually don't bother reading what you've written - it's nearly always wrong.
Oh Don, your back with crap and poorly quoting your references.
I said its not economic to pump water long distances and at around 100 - 200km depending on terrain the cost of building a dam and pumping water exceeds desal water costs. I can repeat again it if you'd like.
Desal and recycled water have the advantage that for all the Australian major centres both are available within a short distance of the geographic centres of the city, thus incurring minimal pumping and capital piping costs.
Desal is not just the solution for the dry middle east, its the solution of choice to much of the drier coastal areas globally or where dam's are simply not practical and/or economic to build. Proof in point every major city in Australia now has one as does much of California and the list goes on.
At no other time do you give a crap about CO2 emissions, so don't try and play this game with me now. Also note that all Australia's Desal plants were built with a commitment to off-set CO2 emissions with RE power, so your comment is as always BS.
Adelaide's Desal plant was needed because of damming of the Murry-Darling basin. So your solution for Melbourne, if indeed does exist and it doesn't is to screw with someone else's water supply, just like Adelaide, which is wide the Fed's co-funded it.
You harp on or rather crap on about the "huge size" of the Melbourne plant, which can supply 33% of Melbourne's needs, but the plant in Adelaide can supply 50% of Adelaide's.
Adelaide's plant has spent most of its life at 10% although operated higher, as the plant is nearly 10 years old , it has basically supplied Adelaide's water supply for one full year. And you wonder why your dam's are not empty??? And unlike Adelaide, Melbourne actually has population growth, so yes its construction is not just for the now, its for the future.
Also interesting that you pick on desal plants being over sized, but isn't that what a dam is all about?
I think you will find the desal plants were approved to proceed in a major drought that left the major centres with serious concerns about their water supply due to population growth. It was nothing to do with climate change. Had the drought continued then by the time the desal plants were available they would have provided the essential water supply. If the drought is broken, then they are on standby or low production until needed. Its call survival Don. As it turns out, most were completed just before or just after the drought officially broke, this time.
Once again, you have replied and failed to state where all these extra dam's in Melbourne can be built, meaning you have no idea. As I said before, Melbourne unlike Sydney and Brisbane has a large number of water storage sources due to a lack of significant rivers. Since they likely picked the best ones easily on, this means what left is small and high cost and now likely developed. But Don still thinks these magical dam location exist....
You always read my posts Don, you will read this one and you will come up with some reply trying to save yourself.
