Supporting information   


The volume reported in the water accounting statement (60,139 ML) represents discharge from five wastewater treatment plants (WWTPs) in the Adelaide region to the sea. The wastewater discharge by WWTP during 2009–10 is shown in the table below.

Quantification approach   


Data source

SA Water: WWTP records.

 

Data provider

SA Water.

 

Method

Five WWTPs discharge wastewater to the sea:

  • Aldinga
  • Bolivar
  • Bolivar—high salinity
  • Christies Beach
  • Glenelg.

The metered volume of wastewater discharged from these WWTPs in 2009–10 was supplied from WWTP records held by SA Water. These metered flows are manually read and recorded by plant operators.

 

Uncertainty

Uncertainty is +/-10% based on meter calibrations.

 

Assumptions, approximations and caveats/limitations

  • This item does not include any community waste management schemes, including the Port Elliot WWTP, which are managed by local councils.
