Review of beneficial reuse and end-use options for brine from the Narrabri region

The Narrabri Gas Project (NGP) was granted development consent by the NSW government in 2020. This project will generate large volumes of saline ‘produced water’, which requires treatment to a standard that will allow for beneficial reuse of the treated water. Beneficial reuse includes crop irrigation, livestock watering and dust suppression. Treatment of produced water by a reverse osmosis water treatment facility will generate brine by-product. Development conditions for the management of produced water include maximising the beneficial reuse of brine and salt, and disposing of salt that cannot be beneficially reused.

The aim of this research project is to review beneficial reuse and end-use options for brine from the Narrabri Gas Project.
CSIRO researchers will collate existing data on brine and salt management in the region; review existing and emerging technologies and solutions; analyse the costs and benefits of brine reuse and end-use options; and share results with the local community.
