Future prospects
Table 1 shows that there is a surplus of available water assets over water liabilities and future water commitments that are expected to be settled within 12 months of the reporting date.
| Volume (ML) | |
| Total water assets at 30 June 2013 | 2,841,107 |
| Less water assets not available to be accessed, taken or delivered within 12 months of the reporting date | |
| Dead storage | 108,471 |
| less total water liabilities as at 30 June 2013 | 0 |
| Subtotal |
2,734,583 |
| less future commitments expected to be settled within 12 months of the reporting date | |
| expected surface water allocation diversion (urban water system) | 480,000 |
| expected surface water allocation diversions |
37,700 |
| expected diversion of other water allocations and rights | 32,529 |
| Surplus of available water assets over water liabilities and future commitments expected to be settled within 12 months of the reporting date | 2,182,407 |
The expected diversions and extractions are based on a rounded average of abstractions made during the 2010, 2011, 2012 and 2013 Accounts. Surface water allocation diversions for the urban system have been sourced from line item 17.12 Surface water allocation diversion – urban water system. Surface water allocation diversions is a rounded average of 17.11 Surface water allocation diversion, and other diversions is the total entitlement of 17.6 Diversions – other statutory rights. This table is only an indication of available future water assets based on the information collected within the National Water Account. Actual available storage over the next 12 months will be influenced by a number of factors such as climate, actual diversions and available volume in storages.
Contingent water assets and contingent water liabilities
a. Contingent water assets
Desalinated water supply to Sydney Water Corporation's distribution system:Sydney's desalination plant at Kurnell has the capacity to produce 91,250 ML per year (Sydney Water Corporation 2013a).
As no desalinated water was transferred into the Sydney region, the remaining production capacity of desalinated water at Kurnell (91,250 ML) can be considered a contingent water asset.
More details on Sydney's desalinated water supply are provided in Desalinated water in Contextual information.
