Comparative year
The volume previously reported in the 2011–12 year included the Lithgow diversion of 17 ML. As Lithgow City Council diversions are now part of the urban water store this volume is now accounted for in line item 11.9 Delivery of water to urban water system under inter-region agreement.
Therefore, the volume reported in the 2011–12 year has been restated as 4,166 ML.
