South East Queensland
17.6 Diversions - other statutory rights
This line item consists of diversions based on riparian water authorisations (RWAs).
The following table shows the breakdown of estimated diversions for RWAs in each water resource plan (WRP) area within the South East Queensland (SEQ) region.
|Water resource plan (WRP) area||Riparian water authorisations|
|Total SEQ region||1,814||3,628|
A riparian right in Queensland is the riparian landholder's access to stock and domestic water via RWAs. The basic right (also known as 'riparian right'), as stipulated in the Water Act 2000 (Qld), is the right of an owner of land adjoining a watercourse, lake or spring to divert from that water source for stock or domestic purposes. This riparian stock and domestic access is separate from an entitlement.
A riparian water acknowledgement must be submitted to the Queensland Department of Environment and Resource Management (DERM) to access this right to divert water. DERM then provides an RWA to the applicant. RWAs are not metered in the SEQ region.
An estimate has been made of the RWAs within the SEQ region. The total number of properties with RWAs was multiplied by an assumed diversion rate of 2 ML per property to obtain an estimate of the volume abstracted.
Assumptions, Limitations, Caveats and Approximations
The assumed diversion rate of 2 ML per property may not be appropriate for all users and adds uncertainty to the estimated value. The number of RWAs reported in the 2011 Account was assumed to be the same as the 2010 Account.
The uncertainty estimate was not quantified.
