Barnett's water pipeline theory mocked
The West Australian opposition has ridiculed Premier Colin Barnett's theory that water would flow from the north of state to Perth across flat land by the force of gravity.
Mr Barnett has revived a widely rubbished plan to funnel water from the Kimberley to Perth via a canal or pipeline, saying it could be a viable option in the future.
Opposition water spokesman Fran Logan mocked the idea and said the cost would be "astronomical", pushing household water bills from $500 a year to $2000.
Water Minister Bill Marmion told parliament a 1996 study on building a pipeline found the transported water would cost $6.50 a kilolitre in today's figures.
By comparison, sourcing water from a desalination plant cost about $2.40 a kilolitre, and water from dams approximately $1.20.
"As we move on, economic conditions may change so it may be a medium-to-longer-term solution ... and in the future the economics of a pipeline may become more viable," Mr Marmion said on Thursday.
Mr Logan said according to a 2006 report a canal would cost more than $14 billion, with 70 per cent of the water being lost through evaporation, while a pipeline would cost in excess of $12 billion.

A few observations -
1) How much would it have cost, if a water pipelines had been built in conjunction with the developments in the North West of WA, during the 1970's & 1980's?
2) What may be the future costs, as Perth Dam levels fall below the current 24% of capacity, as climate change continues to drive rainfall levels lower & heat higher?
3) What may be the future costs, of desalination plants, as future Fossil Fuel prices continue to escalate to 100%, 200%, 300%, 400%, 500% etc of current prices?
Btw, I think it was a Labor minister who first Publicly mooted the idea of this Kimberley-Perth water pipeline.
It is interesting how either being in power or in opposition changes the perspective of many Politicians!
