Water resources - Allocation and Use - Northern Territory
Groundwater Management Unit: Unincorporated Area - Cretaceous Sedimentary
The National Water Reform Framework requires the development of comprehensive systems of water allocations or entitlements, backed by separation of water property rights from land and clear specification of entitlements in terms of ownership, volume, reliability, transferability and, if appropriate, quality. In addition State agencies are required to undertake formal determination of water allocations or entitlements, including allocations for the environment as a legitimate user of water.
Water use estimates have been derived from a number of different methods including the use of licencing systems, information provided as part of the Australian Bureau of Statistics water account (with provider consent) and other information gathered from the State and Territory water agencies. In some cases water use was assumed to be the same as the allocation. For groundwater systems, it is well known that this assumption is often invalid (e.g. typically where use exceeds allocation significantly).
How is the groundwater being used?
Total water use for Unincorporated Area - Cretaceous Sedimentary is 38 ML/yr with a sustainable yield of 878 ML.
How much groundwater is allocated in the Unincorporated Area - Cretaceous Sedimentary Groundwater Management Unit, and for what purpose?
Allocation Methods and Policy:
Currently there is no formal allocation policy, however legislation is in place to enable licencing of bores which are capable of yielding in excess of 15 L/s.
