Pureau — Australia’s Purest Water, trusted by Aussies since 1987
Proudly Australian Owned and Operated.
Purity isn't an ingredient. It's everything we take out.
Most water brands tell you where theirs comes from. We would rather tell you what isn't in it.
The Pureau process is a three-stage system — filtration, reverse osmosis and biological filtration to 0.2 microns. No chemicals, no ozonation, no UV. Every production run is independently tested by a NATA Accredited Testing facility against the parameters of the Australia New Zealand Food Standards Code.

The Pureau process
How we make Australia's Purest Water
Ordinary tap water goes in. Three filtration stages take out what you don't want, with no treatment chemicals. Then it's independently lab tested, filled into BPA Free 10L casks and sent to your local stockist.
Free of chlorine, bacteria, fluoride and sodium. Lab tested.

First stage
Filtration
Carbon and inorganic media remove chlorine, nitrates, iron and sediment. This conditions the water before the high-pressure membrane step.
Second stage
Reverse osmosis
Water is forced through semi-permeable membranes at high pressure. Fluoride, sodium and dissolved solids are rejected at the membrane.
Third stage
Biological filters
0.2-micron absolute filters remove any remaining bacteria and microbes. Samples go to a NATA Accredited Testing facility for independent verification every single production run.
What the Pureau process removes
These are the substances found in Australian tap water and many bottled waters that do not exist in Pureau.
Stage 1
Chlorine
Added to tap water as a disinfectant. Carbon filtration removes it completely.
Stage 1
Nitrates
Common in agricultural catchments. Removed by specialised inorganic media.
Stage 1
Iron and sediment
Dissolved metals and particulate matter from infrastructure and source water.
Stage 1
Stage 2
PFAS
Per- and polyfluoroalkyl substances — "forever chemicals". Removed at two stages: activated carbon filtration, then the reverse osmosis membrane.
Stage 2
Fluoride
State-mandated addition to tap water. Rejected by the reverse osmosis membrane.
Stage 2
Sodium
Dissolved sodium salts present in most Australian tap and spring waters.
Stage 2
Heavy metals
Lead, arsenic, cadmium and chromium. The reverse osmosis membrane rejects dissolved metal ions at 95–99% efficiency.
Stage 3
Bacteria
0.2 micron absolute filtration is the accepted sterilising grade for bacterial removal in food and beverage production.
Independently verified. Every run.
Pureau sends samples to a NATA Accredited Testing facility across every production run at our Erskine Park facility. Results are reviewed and signed off before any product leaves the site.

The empties
More water in. Less rubbish out.
Better for you. Better for the environment.
To match one 10 L cask you would need seventeen 600 mL bottles — on the bench, in the boot, or at the campsite where you carry every empty bottle home again. A Pureau cask holds the water, then folds flat.
Seventeen 600 mL bottles
What it takes to match one cask. Seventeen bottles, seventeen caps, seventeen labels — and a full recycling bin.
One Pureau 10 L cask
The same water, in one pack. Empty, it flattens to the thickness of a piece of cardboard.
Less plastic per litre
One thin liner instead of seventeen rigid bottles, caps and labels for the same ten litres.
Flat when it's empty
The outer carton collapses. It takes up almost no room in the bin, the boot or the camp trailer.
BPA-Free Packaging
Our packaging is carefully chosen to safely protect the purity and quality of Pureau from the moment it leaves our factory until it reaches your glass.
Can't live without it
The water you use most, and think about least.
You drink it, you cook with it, you brew with it, you pack it, you take it away for the weekend. Pureau earns a spot on the bench, not in the back of a cupboard.
In the kitchen
Coffee, tea, smoothies, soups, rice, pasta and more. Pureau is a simple choice for drinking and cooking, wherever water is part of the recipe.
In the school bag
Fill the kids’ drink bottles with Pureau before heading out the door. An easy addition to the everyday lunchbox routine.
On the road
Heading away for the weekend? Pureau is perfect for caravans, camping and road trips, giving you pure water that’s easy to store, carry and pour.
Around the table
A cask on the table beats a bin full of bottles. Pour, top up, keep going.
After a workout
Whether it’s a morning walk, gym session or weekend sport, keep Pureau nearby to help make hydration part of your everyday routine.
WHEN IT REALLY MATTERS
The purest choice for your family
When it comes to your family, you want to know that what you’re putting into their glass is as pure as it can be.
That’s why families have been choosing Pureau for almost forty years.
No added chemicals. No unnecessary extras. Just pure water, the way nature intended.
-
Supplements and powders
When you’re carefully choosing what goes into your body, it makes sense to mix your supplements with water that’s free from unwanted impurities.
-
Infant formula preparation
For generations, Australian parents have chosen Pureau when preparing infant formula. Always follow the formula manufacturer’s preparation instructions for best results.
-
CPAP and medical devices
Some CPAP and humidification devices recommend low-mineral water to help prevent deposits and build-up in the reservoir. Pureau provides a naturally low-mineral option.
-
Coffee machines and kettles
Hard-water minerals can leave behind calcium and limescale. With Pureau, there’s less mineral build-up inside the appliances you rely on every day.
-
Older Australians
As we get older, everyday wellbeing becomes even more important. Choosing pure water is a simple way to take greater care with what you drink, every day.
Because when it really matters, purity matters.
Pureau. Pure water. Nothing else.

Not all Reverse Osmosis systems are the same
A home filter and a Pureau plant are different things.
Reverse osmosis is just one step in our process. A Reverse Osmosis system alone does not guarantee 100% purity. That's why we independently verify the quality of every production run. The result depends entirely on what surrounds the membrane — and most home systems leave out the parts that matter most.
The storage tank problem
Most under-bench and benchtop home Reverse Osmosis units store purified water in a pressurised rubber bladder tank. Still water sitting in a rubber vessel in a warm cabinet is a known environment for bacterial regrowth. By the time it reaches your glass, the purification has been partially reversed.
Filter fatigue goes undetected
Home systems depend on the owner replacing pre-filters every 6 to 12 months. An exhausted carbon pre-filter allows chlorine and organic compounds through to the RO membrane, degrading it from the front. Contaminant rejection rates fall quietly, with no alarm and no visible sign.
No biological filtration stage
A Reverse Osmosis membrane rejects dissolved solids — it does not filter bacteria. Pureau adds a third stage of biological filtration to 0.2 microns absolute after the membrane. Most home systems stop at the membrane. That gap is where bacteria live.
Stage count is not purity
Some home systems are marketed as 7-stage or 9-stage. In most cases the additional stages are mineral-addition cartridges, alkaline stones or UV lamps — each addressing taste or marketing, not purification. More stages does not mean cleaner water.
Cold water cuts performance
Reverse Osmosis membrane efficiency drops significantly in cold water — a common condition in Australian winters, particularly in southern states. Rejection rates can fall by 15 to 25 per cent in cold supply water with no indication to the user that the system is underperforming.
No independent verification
Pureau sends samples to a NATA Accredited Testing facility across every production run. A home Reverse Osmosis system has no ongoing third-party testing. What the membrane claims to remove, and what it actually removes on any given day, are two different things without verified data to confirm it.
The real numbers
What a home Reverse Osmosis actually produces.
NSF/ANSI 58 — the standard most home Reverse Osmosis units are certified to — only requires a unit to demonstrate 75% TDS rejection at test conditions. Real-world performance, with aged membranes and suburban water pressure, falls further. These are established industry and independent research findings.
| Contaminant | Pureau industrial | Home Reverse Osmosis — new, well-maintained | Home Reverse Osmosis — typical real-world |
|---|---|---|---|
| TDS (dissolved solids) | Not detected (NATA Accredited Testing facility) | 88–94% | 60–80% |
| Nitrates | Not detected (NATA Accredited Testing facility) | 75% | As low as 50% (NSF minimum) |
| Arsenic | Not detected (NATA Accredited Testing facility) | 85–90% | 70–80% |
| Fluoride | Not detected (NATA Accredited Testing facility) | 85–92% | 65–80% |
| Bacteria (post-tank) | Removed to 0.2µm | Bacterial regrowth risk | Bacterial regrowth risk |
| Independent verification | Every run — NATA Accredited Testing facility | None | None |

Home Reverse Osmosis real-world figures reflect typical consumer-grade systems after 12–24 months of use at suburban mains pressure (50–80 PSI). Pureau figures reflect production results verified by a NATA Accredited Testing facility.
A home Reverse Osmosis cannot produce Pureau.
The pressure is not high enough. The pre-treatment beds are not there. The biological filtration stage after the membrane does not exist. The storage tank introduces contamination the membrane just removed. And there is no independent laboratory test to tell you any of this is happening.
Pureau operates at industrial membrane pressures home systems cannot physically reach, through carbon and sand pre-treatment banks, through a three-stage process that ends with biological filtration to 0.2 microns absolute — then sealed, not stored in rubber. Every production run is tested independently. Not occasionally. Every run.
Common questions
Frequently asked questions
Where do I get my minerals if Pureau has none?
From food. Dietary minerals come overwhelmingly from what you eat, not what you drink — the mineral content of tap and spring water is incidental rather than nutritionally significant. Pureau's job is hydration. If you want minerals in your water you can add exactly the ones you choose, in the amount you choose, to a known starting point of zero. That isn't possible with any water that already has minerals in it.
What is Pureau?
Pureau is 100% purified water produced through a three-stage industrial process: carbon and sand filtration, high-pressure reverse osmosis, and 0.2-micron biological filtration. It contains no minerals, fluoride, chlorine, sodium or bacteria.
Does Pureau contain fluoride?
No. Australian tap water is fluoridated by state water authorities. The Pureau reverse osmosis process removes fluoride completely. Confirmed by independent testing by a NATA Accredited Testing facility across every production run.
Is Pureau tested regularly?
Yes. Pureau sends samples to a NATA Accredited Testing facility across every production run. Results are reviewed before any product leaves the facility. Not batch tested. Not sampled. Every run.
How can you be sure there is no contamination during production?
All piping in the Pureau facility is food-grade stainless steel. Every morning, 45 minutes before production begins, the entire system is steam sterilised. No cleaning chemicals are used — steam is the sterilant. The water never touches anything that could reintroduce contamination.
Is Pureau tested for microplastics?
Microplastic testing is not part of the standard production run testing protocol. The main microplastic risk with any packaged water is the packaging itself, not the source water. Pureau uses an approved supplier programme for all packaging materials. The Bag in Box format uses significantly less plastic contact surface per litre than single-serve bottled formats, and the 0.2-micron biological filtration stage removes any particulates present in the production water before filling.
Why does pure water have a lower pH?
Pureau leaves the facility at pH 7.1–7.4. Without dissolved minerals to act as buffers, the water absorbs a small amount of CO₂ from the air, lowering the pH over time. This is normal chemistry — the same process that occurs with rainwater — and has no health significance.
What formats does Pureau come in?
600 mL bottles (6-pack and 12-pack), 2 L bottles, 5 L Bag in Box casks and 10 L Bag in Box casks. The cask’s inner bag collapses as water is dispensed, keeping the remaining water sealed from air.
Is the packaging recyclable?
The outer carton is fully recyclable kerbside. The inner liner is not currently accepted in kerbside collections — check locally for soft-plastic take-back options in your area. One 10 L cask replaces 17 individual 600 mL plastic bottles.
How long does an open cask last?
Once tapped, use within 30 days and keep out of direct sunlight. The Bag in Box design keeps air out as water is dispensed, so the water stays fresh throughout.
Where is Pureau made?
Pureau is manufactured at the Erskine Park facility in Western Sydney, operated by Australian Beverage Holdings. Australian owned and operated.
Where can I buy Pureau?
Pureau is available at Woolworths, Coles and IGA stores nationally, and online via Woolworths, Coles and Amazon AU for home delivery.
