Overview
Wastewater is the used water from households and business that is disposed of through the sewerage network (or into septic tanks in some areas). Wastewater is 99.97 per cent water as the majority is sourced from showers, baths and washing machines. The remainder is dissolved and suspended matter.
Treated wastewater is discharged from a wastewater treatment facility after it has passed through treatment processes to reduce its nutrient and bio-chemical load.
This can provide a secure and sustainable source of water that is rainfall independent unlike ‘traditional' water supply options. Further treatment may be required, depending on the intended use, if treated wastewater is considered as a non-drinking water source option.
