South Australian Current Regulations South Australian Current Regulations4—Determination of notional cost
The Trust must determine in respect of each contribution year an amount (which
is to be a notional amount for the purposes of this Part) that in its opinion
will be required to cover the cost of pumping sufficient water into the
disposal basins to prevent any increase in the volume of the ground water
mound and the underground water above the layer of Blanchetown Clay in the
Scheme Area during that year.
