Remote Indigenous Community Water Supply


In 2017, Moerk Water was hired as part of a team to carry out a feasibility study identifying water supply options for a remote aboriginal community in Western Australia with 300 permanent residents and 500 visitors three times a year. The community already had existing bores and Reverse Osmosis but this water supply option was insufficient for the entire community. The bores the community were relying on were either low yielding freshwater bores or high yielding saline bores. The feasibility study explored several options including blending different bores as a new feed to the Reverse Osmosis plant, recycling grey and black water, upgrading the existing Reverse Osmosis plant and treating the Reverse Osmosis reject stream with a solar still. Following the first report, the project moved into its second stage which was a single solution recommendation based on the range of options presented in stage one of the study.



  • Aboriginal community in the Central Desert region had existing water treatment supply system that was insufficient for the community’s needs
  • Moerk Water was part of the project team consulted to prepare a feasibility study of different water supply options for the community
  • The feasibility study recommended a range of different options including upgrading the Reverse Osmosis unit, using different bores to feed the Reverse Osmosis system and treating the reject from the water treatment system with a solar still
  • The second stage of the project was to identify the best of the options presented in the feasibility study and present it to the Housing Authority.
