This line item reflects the liability to the connected surface water store from the allocation/claim considered for the regulated urban water access entitlement category. The volumetric value for the allocation/claim for the regulated urban water access entitlement category for 2009–10 is 1,022,865 ML.
Refer to the note Water rights, entitlements, allocations and trade for the National Water Account 2010 (the 2010 Account) for an interpretation of regulated and unregulated entitlements.
The volumetric value for the line item is based on entitlement values for the water utilities and an assumed allocation of 100% at the beginning of 2009–10 (see the following table).
| Utility type | Allocated volume* for 2009–10 (ML) | Utility name | Diversions associated with the allocation |
|---|---|---|---|
| Major utility | 987,000** | The Sydney Catchment Authority | Diversions to Sydney Water Corporation for Sydney Greater Metropolitan Area Diversions from Bendeela Pondage to Kangaroo Valley for Shoalhaven City Council Diversions from Wingecarribee Reservoir to the Wingecarribee Water Treatment Plant (WTP) for Wingecarribee Shire Council Diversions to some retail customers |
| Local water utility | 35,865** | Goulburn Mulwaree Council | Goulburn Mulwaree Council diversions to Goulburn WTP from storage reservoirs |
| Lithgow City Council | Lithgow City Council diversions to Oakey Park WTP from a storage reservoir | ||
| Shoalhaven City Council | Sydney Catchment Authority diversions from Lake Yarrunga (Tallowa Dam) for pumping at Burrier for Shoalhaven City Council | ||
| Wingecarribee Shire Council | Wingecarribee Shire Council diversions to Medway and Bundanoon WTPs from storage reservoirs | ||
| Total | 1,022,865 | ||

* Allocated volume is based on a 100% assumed allocation. ** Entitlement values used to estimate allocated volume are based on information available in the Draft Water Sharing Plan—Greater Metropolitan Unregulated River Water Sources and information received from entitlement holders. The National Water Account 2010 water accounting reports for the Sydney region were compiled before finalisation of the draft water sharing plans. Therefore, stated entitlement values are provisional and an estimate. |

The volumetric value for the announced allocation/claim for regulated urban water access entitlements/arrangements in the Sydney region was estimated by mapping entitlement values stated in the draft water sharing plan to the relevant category of entitlements, and applying an assumed allocation 100% at the beginning of 2009–10. Entitlements for the Sydney Catchment Authority (major utility) and four local water utilities—Shoalhaven City Council, Goulburn Mulwaree Council, Lithgow City Council and Wingecarribee Shire Council—were taken into account.
The volume was estimated. Uncertainty is ungraded.
There is no process of formal allocation announcement for the entitlement holders considered in this line item. Taking into consideration the water availability at the beginning of 2009–10, an allocation of 100% was assumed.
The NSW Office of Water records entitlements for the line item as unregulated for major utilities and local water utilities (to harvest unregulated inflow). The Bureau of Meteorology has defined these entitlements as regulated for the purposes of the 2010 Account and listed under urban category (see the note Water rights, entitlements, allocations and trade).
Calculated announced allocation/claim includes both water available to the end users and system losses. Entitlement values used for the calculation of announced allocation/claim are provisional and an estimate.
