Quantification approach   


Data source

ActewAGL Water Data Warehouse.

Queanbeyan City Council (QCC): QCC database.

 

Data provider

ActewAGL and QCC.

 

Method

Treated wastewater discharged to the connected surface water store was measured by wastewater treatment plant outflow flow meters. The 2009–10 discharge volume was extracted from the ActewAGL Water Data Warehouse and the QCC database. Only the Lower Molonglo Water Quality Control Centre and the Queanbeyan wastewater treatment plants discharge treated wastewater to the surface water store.

 

Uncertainty

Derived from measured data. Estimated uncertainty is +/–5%.

 

Assumptions, approximations and caveats/limitations

  • Fyshwick Wastewater Treatment Plant has not been included in this line item, as discharges from this facility are directed back to the wastewater system or to the recycled water system.
