Total Dissolved Solids (TDS)
- A new way of working with woks saves water
- Harvesting rainwater, treating waste water and making it all available for reuse
Did you know?
A waterless wok can save up to 12,000 litres of water a day.
Sustainability Indicator:
Total Dissolved Solids (TDS)
Commitment:
To reduce the concentration of TDS (salt) discharged into our sewers, by our industrial customers, by 20% or 49 tonnes per day by 2009-10.
How we’ve performed:
Total dissolved solids |
2005-2006 |
2006-2007 |
2007-2008 |
Median concentration of TDS flowing into Western Treatment Plant (milligrams per litre) |
950 |
970 |
1014 |
Trade waste customer loads (tonnes per day) |
104 |

98 |
Maximum target (tonnes per day) |
152 |
144 |
125 |
Looking ahead:
We will continue to focus on avoiding contaminants at the source, which will be a key to ensuring that the Western Treatment Plant effluent and biosolids are sustainably recycled.
