Australia's national science agency CSIRO is repurposing water-treatment know-how built up over decades of work with the mining sector to help regional communities and industries facing variable groundwater quality, limited infrastructure and expensive waste disposal, the agency said in a release published on 4 October 2026 (CSIRO). The programme spans a nature-based potable water scheme with Indigenous partners in North Queensland, an abattoir wastewater reuse trial in Tamworth, and containerised desalination pilots with Water Corporation Western Australia.
Key takeaways
- CSIRO is working with the Nywaigi people at Mungalla Station near Ingham on a plant-based, nature-based treatment train to secure potable water for the Indigenous-owned cattle station and ecotourism site (CSIRO).
- A forward osmosis plus reverse osmosis trial at Tamworth Regional Council's treatment plant recovered more than 80 per cent of abattoir trade waste as irrigation-quality water, with no microbes detected in the recovered stream (CSIRO).
- A 20-foot containerised desalination pilot in Western Australia is rated at up to 10 kilolitres of desalinated water per day and is co-funded through the Australian Government's National Water Grid Fund (CSIRO).
- A thermal membrane technology developed to cut brine volumes is being trialled through the Australian Coal Association Research Program on coal mine brines and acidic mine water, and is also the basis of a CO2CRC proof-of-concept pairing brine with captured industrial CO2 (CSIRO).
- CSIRO is not yet running a full-scale abattoir reuse plant in the region; the Tamworth work is a preliminary study demonstrating technology transfer between mining and municipal-industrial users (CSIRO).
What happened: from mine water to regional supply
CSIRO's release frames the work as a deliberate cross-sector transfer: decades of treating saline, acidic or mineral-laden streams at mine sites have built membrane, brine-management and process-water know-how that the agency is now applying to drought-prone regional users (CSIRO). "Each solution is shaped around local water chemistry, operating conditions and user needs, rather than relying on a one-size-fits-all treatment system," the agency said (CSIRO).
At Mungalla Station, on Nywaigi Country about 1.2 kilometres from the nearest reticulated supply, CSIRO is working with the Nywaigi people to convert locally sourced plant material into a structured carbon treatment media, with delivery partner On Common Country handling training for local operation and maintenance (CSIRO).
At Tamworth Regional Council's plant, the abattoir trial paired forward osmosis, which uses a concentrated draw solution to pull water across a membrane, with reverse osmosis to polish the recovered stream for irrigation reuse; CSIRO reported the trial recovered more than 80 per cent of the feed and that no microbes were detected in the recovered water, although a full-scale plant in the region is not yet operating (CSIRO).
In Western Australia, CSIRO is trialling its membrane stack with Water Corporation in a 20-foot shipping-container skid rated at up to 10 kilolitres per day of desalinated product, co-funded through the National Water Grid Fund; one site is testing whether adding forward osmosis upstream of the existing desalination step lifts overall recovery, while another is reprocessing an existing forward- and reverse-osmosis waste stream (CSIRO).
Brine reduction is being pursued through a thermal membrane technology now at pilot and prototype scale, with Australian Coal Association Research Program trials on coal mine brines and acidic mine water, and a CO2CRC proof-of-concept combining industrial CO2 with brine to explore a saleable product (CSIRO).
Specification read
The headline throughput figures reported in the source translate to buyer units as follows: the Western Australia pilot is rated at up to 10 kL/day, or roughly 10 m³/day, a small modular desalination and forward osmosis test bed rather than a municipal train; the Tamworth abattoir trial recovered more than 80 per cent of the feed through a forward osmosis plus reverse osmosis sequence producing irrigation-quality reuse water with no microbes detected, which is a tertiary / reuse polish train applied after the existing biological step rather than a greenfield build. No flow in m³/day, influent BOD/COD, population equivalent or treated volume for the Mungalla nature-based system is reported in the source, so the scale of that project cannot be quoted and is not inferred here. For a plant manager or utility engineer, the relevant treatment stages to evaluate are screening, primary clarification, biological treatment (the existing step at Tamworth), a tertiary membrane pair (forward osmosis followed by reverse osmosis for reuse and recovery uplifts), and a brine reduction / concentrate management step, with disinfection to the irrigation or potable end use. If your site runs an industrial wastewater train with a biological stage feeding irrigation reuse, and you are chasing double-digit recovery uplifts with a containerised, transportable footprint rather than a new civil build, this work sets the engineering language for evaluating paired forward and reverse osmosis pilots and concentrate valorisation pathways. Procurement leads tracking regional Australian programmes should note the National Water Grid Fund co-funding on the Western Australia pilot and the technology-transfer framing that lets membrane assets originally specified for mine-affected water be redeployed on municipal and food-processing effluent.

FAQ
What is the largest flow rate reported for the CSIRO regional pilots?
The release reports a 20-foot containerised pilot in Western Australia rated at up to 10 kilolitres of desalinated water per day; no higher flow figure is reported (CSIRO).
How much of the abattoir wastewater was recovered at Tamworth?
CSIRO reports the forward osmosis plus reverse osmosis trial recovered more than 80 per cent of the water, with no microbes detected in the recovered stream, though a full-scale plant is not yet operating in the region (CSIRO).
Who is funding the Western Australia containerised desalination trial?
The pilot is run with Water Corporation Western Australia and is co-funded through the Australian Government's National Water Grid Fund (CSIRO).
Is the Mungalla project a full-scale drinking water plant?
No; the release describes it as a nature-based treatment approach using locally sourced plant material converted into structured carbon, with design and training for community handover, and does not report a design flow or capacity (CSIRO).
