Presentation outline
Brief background on water accounting in
Australia
Framework
What is achievable based on currently
available data
Preliminary output
Shortfalls in current data
Issues
Water Account, Australia
• Last released May 2004
•Next edition due Nov 2006
• Previous edition in 2000
• 11 Chapters
• Mostly water supply and use in
the economy
• Plus some information on water
stocks, environmental flows and
water trading
• Data for Australia and for each
of the Australian states (except
NSW and ACT are combined)
Drainage Divisions and River Basins
Point and Non-point Sources of
Emissions
Point source emissions are emissions
that can be clearly related to a
geographical location of where
wastewater is discharged
Waste water treatment plants, industry
Diffuse (non-point source) emissions are
source where a single point of origin
cannot be identified
Agriculture, forestry, urban areas
Framework
Method
Based on SEEA framework
Data from National Pollutant Inventory
Reporting on substances based on key
elements reported to NPI
Data source:
National Pollution Inventory
• Run by department of environment
• Over 3,000 facilities reporting
• Reporting only by facilities that exceed
thresholds set by NPI (ie only large polluters
required to report)
• Diffuse emissions estimated for particular
catchments of interest
Preliminary Output
Point source emissions for Australia for selected
substances
State/territory level data for point source
emissions to water for phosphorus and nitrogen
Diffuse nutrient emissions to water by catchment
Pollution intensity ratios for selected substances

Shortcomings evident in
Australia
Incomplete coverage of emissions by NPI
Estimates from industry based on production not
on concentrations of substances in incoming and
outgoing flows (hence double counting likely)
Lack of regular data for diffuse emissions
Household data are aggregated with total urban
diffuse emissions in NPI
Agriculture currently included as diffuse
emissions and not are reported regularly
Issues
• How to work effectively with other agencies to
ensure better data quality
• Need to recognise that a complete for Australia
is not required (ie water pollution/water quality
are not an issue for much of Australia
• Need to improve links between water
emissions, water quality and river health
