The MGP started in 2004 until 2010 the CSG water was pumped into holding ponds. The 2010/11 wet season floods forced Arrow/AGL to pump this brackish water into the Isaac river. A reverse osmosis (RO) plant was installed in late 2011 which concentrated the salts and 80% of the brackish water was upgraded and used eg coal washing plants. This left 20% of the CSG water now brine to be stored in lined ponds.
The QLD government wants to get rid of the brine ponds as a result of gas extraction. The only feasible way to date is using a crystalliser plant, then store the salts in a lined fully enclosed site capped with top soil. Needless to say the farmers and greens aren't happy about that.
Parkway (PWN) say they have a better solution, although they have not disclosed the technical details. If interested go to PWN and look at the Ann 22/6/23...QBS releases Master Plan Presentation.
I do not hold PWN shares.
