Boosting use of recycled water in agriculture is a critical part of the equation as water efficiency becomes critical and squeezing more out of each litre of water becomes a more normal issue in Australia. Israel already boasts of getting at least two uses out of each litre of water.......Australia is a long way behind that claim.
But some recently funded research is at least examining options to boost recycled water use while managing salt, a critical problem in drier areas of Australia, although not so important in the wetter areas of the north......we do not even do much water recycling, and some utilities seem to not care much about water recycling with the PAWC in the NT one of the worst in Australia with very low percentages of effluent recycled.
Maybe if this new research shows promise we shall all be drinking wine made from grapes grown in McLaren Vale on recycled wastewater.
The new research to expand the use of water recycling for irrigating South Australia’s vineyards has been initiated by the Australian Water Recycling Centre of Excellence.
In our region near Darwin, neither of the two issues - quality production and use of organic residuals in horticulture [ but some goes into home gardens] nor effluent recycling and reuse are widely used.
