here is some info from plantations australia group re the plantations in melb water supply with the pipeline to take into consideration when campaigning against the pipeline

the new pipeline to be built on the goulburn river near yea, will mean that melbourne will now have 3000ha of hancock pine and probably another 1000ha of other pine and bluegum in its water supply.

the hancock pine is located on the acheron river, upstream of the new offtake. the hancock pine will use about 30,000ML of water per year. costing at current melbourne drinking water prices of $1019ML will make these plantations, along with korweinguboora in geelongs water supply the most pricy in the state.

the acheron river plantations will be using about $30 million worth of water per year. or $300 million per decade.
