The Point Paterson Desalination Plant was a planned municipal-scale solar-powered desalination plant with land-based brine disposal near Point Paterson in the locality of Winninowie in the Australian state of South Australia about 13 kilometres (8.1 mi) south of the city centre of Port Augusta.

The plant would have integrated renewable energy and desalination technologies to create environmentally-friendly electricity and water.

In particular, the project would have significantly reduced the usual greenhouse impacts associated with grid electricity demand for desalination.

The profits from the salt harvesting will be used to offset the cost of the desalination process while simultaneously preventing wastewater from being pumped back into the Spencer Gulf.
