Sydney
18.7 Groundwater extractions – other statutory rights

Supporting information

This line item refers to all groundwater estimated to have been extracted (19,352 ML) in the Sydney region under groundwater basic landholder rights. This includes rights to extract water to meet basic requirements for household purposes (non–commercial uses in and around the house and garden) and for watering of stock. This water cannot be used for irrigating crops or garden produce that will be sold or bartered, for washing down machinery sheds or for intensive livestock operations.

The total extraction volume is assumed to 100% of the right. In times of limited supply, there may be restrictions on taking water for domestic and stock use. 

A breakdown of the groundwater basic landholder rights is provided in the following table.

Quantification approach

Data source

Provided by

New South Wales Office of Water.

Method

The annual extraction for domestic and stock rights in the water accounts is assumed to be 100% of the groundwater basic landholder right stated in the Water Sharing Plan for the Greater Metropolitan Region Groundwater Sources.

Assumptions, limitations, caveats and approximations

It is assumed that the total extraction for the region is 100% of the entitlement. Actual extraction of groundwater has not been quantified.
