14.2 Adjustment and forfeiture of groundwater allocation – urban water system
The volume presented in the water accounting statements (412 ML) represents the volume of groundwater allocation that was forfeited for urban groundwater entitlements in the Melbourne region during the 2011–12 year. Carryover rules for groundwater entitlements throughout the Melbourne region do not allow unused water to be carried over at the end of the year. Therefore the volume of groundwater forfeited is equal to the volume of unused allocated water.
Given that no groundwater was extracted under urban groundwater entitlements during the 2011–12 year, the volume forfeited is equal to the volume allocated (reported at line item 22.2 Groundwater allocation announcements – urban water system).
In the 2011 Account, it was not possible to separate urban and non-urban entitlements to groundwater. Therefore, all adjustments/forfeitures to groundwater entitlements were reported at line item 14.1 'Adjustment and forfeiture of groundwater allocation'.In the 2012 Account, data provided has enabled urban entitlements to groundwater to be reported separately in the Melbourne Account. Consequently, the volume has been restated as 401 ML.
