Supporting Information
Anyone who holds a groundwater basic right can 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, washing down machinery sheds or intensive livestock operations. A breakdown of the right is provided in the following table.

As recorded by the NSW Office of Water, there is a 19,652 ML groundwater basic right available in the Sydney Region. The annual extraction for a groundwater basic right was assumed to be the figure stated in the Draft Water Sharing Plan – Greater Metropolitan Region Groundwater Sources (100% of the right); however, in times of limited supply, there may be restrictions on taking water for domestic and stock use.
