South East Queensland
5.2 Surface water allocation remaining - urban water system
Supporting Information
a. Overall
This line item represents the claims on the region's surface water held on behalf of the region's urban water system at the beginning and end of the 2010–11 year.
Allocation carry-over from one water year to the next does not occur in the South East Queensland (SEQ) region. All unused allocation at the end of a water year is forfeited.
Where a water supply scheme (WSS) has a water year that does not match the 2010–11 year of 1 July – 30 June, there is potential for claims to be remaining at 30 June as the water year has not concluded.
In all WSSs for which urban entitlements exist, the water year matches the 2010–11 year, so there are no claims remaining at 30 June 2010 or 30 June 2011 and the volume has been reported as zero.
b. Urban surface water allocation remaining – reconciliation
The following table shows the urban surface water allocation reconciliation. Due to the very wet year, demand was lower than in previous years and combined with the 100% allocation announcements, this has resulted in a higher forfeiture of urban surface water allocation (around 58%).
Urban surface water entitlements have a component included within them to allow for some future population growth. A component of the forfeiture may be attributed to this reason.

c. Urban entitlements
For the purpose of the 2011 Account, urban claim on surface water only includes the SEQ Water Grid Manager and Toowoomba Regional Council entitlement allocations, as they have been identified as the urban holders of entitlements in the resource operation plans (ROPs).
Other organisations may hold supplemented entitlements for some form of urban use, but, as urban use is not identified on entitlements, these could not readily be identified. For this reason, a small number of entitlements that may fall into this category are included in line item 21.1 Surface water allocation announcements.
In Queensland, entitlements and allocations do not have intended use as an attribute, and all metered abstractions do not have entitlement priority or use as attributes. Urban holders of entitlements were individually determined by obtaining all entitlement volumes from the Gold Coast, Logan Basin and Moreton ROPs schedule of water allocations listed for the SEQ Water Grid Manager and Toowoomba Regional Council.
Comparative year
This line item was not reported in the 2010 Account. A volume of 0 ML should have been reported as the opening and closing balance for this line item.
