11.18 Increase of urban claim on surface water

This line item consists of surface water allocation announcements for entitlements held by urban utilities.

The following table shows allocation announcements by water supply scheme (WSS) and water resource plan (WRP) area held by urban utilities. All allocation announcements were 100% in the 2010–11 year.

Notes:

1. SEQ Water Grid Manager was granted an extra 7,700 ML of high-priority water entitlement for the 2010–11 water year in the Nerang WSS from the strategic reserve. More information on this can be found in the amended Gold Coast Resource Operation Plan (2009).

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.

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.

Queensland Department of Environment and Resource Management (DERM), ROPs and announced allocation data.

DERM.

Urban holder entitlements were defined as high-priority group supplemented entitlements held by the SEQ Water Grid Manager or Toowoomba Regional Council.

The volumes of entitlement were obtained from the Moreton, Logan Basin and Gold Coast ROPs Schedule of Water Allocations (Queensland supplemented water allocations are equivalent to regulated entitlements of the 2011 Account).

Announced allocation of 100% was given for all urban utility's entitlements for the 2010–11 year, making the allocation announcements equal to the nominal entitlement volume.

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.

There was no uncertainty associated with this value.

This line item corresponds to line item 25.1.2.4 Allocation announcement on regulated flows – high security, urban holder reported in the 2010 Account.

In the 2010 Account, a volume of 0 ML was provided for Cressbrook Creek WSS allocation announcements. In the 2011 Account, a value of 10,000 ML was provided for Cressbrook Creek WSS allocation announcements, as these entitlements should have been listed as urban entitlements. Similarly, 2,196 ML of entitlements from the Warrill Valley WSS should have been listed as urban entitlements. This has resulted in an increase in the urban entitlements shown in the 2011 Account and has required a prior period correction for 2010 Account.

The following table compares the value at 30 June 2010 reported in the 2011 Account with the corresponding value reported in the 2010 Account.
