Treated effluent through indirect potable re-use
Orange City Council is examining the use of all treated effluent the city uses.
Currently all of Orange's treated effluent is used by Cadia Valley Operations, to supplement the mine's fresh water sources in the Lachlan Valley.
As the city grows, there will be additional effluent produced to exceed the 10 mega-litres per day Cadia needs for its mining operations.
The Council is examining using this additional effluent when it becomes available in the future.
If this water was to be recycled into the city's drinking supplies, a major treatment plant would have to be constructed on the back end of the sewerage plant to make the water safe for blending into the drinking supplies.
