Entitlement volumes

Table 2: Groundwater entitlements at 30 June, Warrion WSPA

Use type	2021-22 (ML)	2020-21 (ML)
Licensed use (non-urban)	14,073	14,075
Total	14,073	14,075

Use type	2021-22 (ML)	2020-21 (ML)
Licensed use (non-urban)	14,073	14,075
Total	14,073	14,075

Available water and use

The table below shows the total water available and used under entitlements, and estimated domestic and stock use in 2021-22. Total water available under entitlements is the sum of: opening carryover, allocation issued and the net of the in/out trade of water.

Estimated domestic and stock use is calculated based on an assumed usage per registered bore per year. In this WSPA, 1.5 ML usage per bore per year is assumed.

More information on groundwater use and availability has been detailed in the How do we account for groundwater section.
