Changes to this issue
The 2017-18 Water Account, Australia (WAA) features a number of changes from previous editions. These changes were implemented to further align the account with the System of Environmental-Economic Accounting (SEEA) Water framework, modernise the processing system, adopt new data sources, and standardise processes across geographies.
The 2017-18 Water Account, Australia (WAA) publication has undergone a methodological review. The updated methodology has resulted in changes to the previously published estimates. For a summary of this methodology refer to the Explanatory Notes.
Regulated discharge has been re-defined as return flows, consistent with the System of Environmental Economic Accounting (SEEA) Water framework.
The conceptual underpinning of consumption has been aligned with the SEEA water framework.
- Previous consumption equation:
|(Self-extracted use + Distributed water use + Reuse water use) - (In-stream water use - Distributed water supplied to other users)|
- Current consumption equation:
|(Self-extracted use + Distributed water use + Reuse water use + Wastewater use) - (Distributed water supply + Reuse water supply + Wastewater supply + Return flows)|
Consumption is not included in the supply and use tables due to incomplete data in wastewater supply and return flows, however total economy consumption is included in the summary tables using the following equation.
- Total economy consumption equation:
|Total self-extracted use - total return flows supply|
A flat file (.csv) is now included in the publication for easy data manipulation by users. It includes all physical and monetary supply and use tables.
The following data cubes have been discontinued:
- Experimental soil water estimates.
- Industry highlight: Agriculture.
Additional agricultural water use data can be sourced from the following publications:
- Water Use on Australian Farms (cat. no. 4618.0).
- Gross Value of Irrigated Agricultural Production (cat. no. 4610.0.55.008).
Within all physical supply and use tables the following changes have been made:
- Removal of the consumption column.
- Inclusion of wastewater supply and use, with wastewater supply recorded as not available.
- Removal of in-stream use as its own category. In-stream use is included in:
- self-extracted use
- return flows supply
- Removal of self-extracted estimates for Households, Aquaculture, Forestry and Logging, and Fishing, Hunting and Trapping.
- Removal of all estimates for Agriculture, Forestry and Fishing Support Services.
Within the monetary supply and use tables the following changes have been made:
- Removal of the rural and urban categories for water supply and use.
- Inclusion of the distributed and reuse water categories for water supply and use.
Inclusion of social benefits in kind as a distinct category.
