The wipes market, and the uses for wipes, has exploded. A stroll down any supermarket aisle now reveals wet wipes for make-up removal, toddlers' noses, floor cleaning, toilet cleaning, toilet training and even (wait for it...) adult bums – promising to leave users "extra clean and fresh". 

To make things even easier for us consumers, we're told (on the packaging) that many of these wipes are now "flushable", which means rather than using the bin, you can toss it into the toilet and flush it out of your life just like toilet paper.

But are flushable wipes really flushable? 

Not according to Australia's water service providers, who are spending an estimated $15 million a year, and growing, to clear blockages they say are largely caused by wet wipes.

The competition regulator isn't too impressed either. On 12 December it announced impending court action against flushable wipes makers Kimberly-Clark Australia and Pental for making false or misleading claims by saying their products disintegrate as well as toilet paper. 

"The ACCC alleges that the impression given by the representations which Kimberly-Clark and Pental each made about these products was that they were suitable to be flushed down household toilets in Australia, when this was not the case," ACCC Chairman Rod Sims says.

What flushable wipes are doing to the wastewater system

"Just because something is flushable doesn't mean it breaks down," says Sydney Water media and communications advisor Peter Hadfield, holding up his mobile phone. "Technically my phone is flushable, but that doesn't mean it should go down the toilet."

While the makers of flushable wipes claim these products are "designed to dissolve and disintegrate" and "break up ... like toilet paper", those who work in the wastewater industry and plumbers across the land tell a different story.

Workers told us they remove serious blockages caused by wipes at least once every two weeks

Our visit to Sydney Water's Malabar wastewater facility confirmed the havoc being wreaked by these products. Workers there told us they remove serious blockages caused by wipes at least once every two weeks, and showed us the balls of tangled and sodden wipes collected in the system's screening process.

"It's had a huge impact on our day-to-day work. The wipes have made a lot of things go wrong. We have to get in there and shovel it all out manually," says Fiona Copeman, who works as a production officer at Sydney Water. 

"It's very unpleasant and labour-intensive, and there's been a real increase in these wipes coming through. And if they aren't taken out in our treatment plants they end up in our oceans and creeks."

We contacted a number of water services around Australia who all confirmed that there's been increase in wet wipes blocking pipes and causing problems over the past few years. Queensland Urban Utilities says responding to blockages now costs the organisation approximately $2.5 million  a year, with wet wipes largely to blame.

As can be expected, these growing maintenance costs will soon start coming out of our own pockets in the form of higher water bills.

What flushable wipes are doing to backyards

Many wipes don't even make it off the property where they've been flushed. When this happens, it's the property owner who's liable for the cost of removing the blockage.

Sydney plumber Darren Clancy says he's spending an increasing amount of time pulling wet wipes out of customers' pipes, and that clients are genuinely surprised to find that wipes labelled as flushable can cause such damage – "they usually find out when I hand them a bill for $1000".

Customers have had their backyards covered in raw sewage when blocked pipes backed up and overflowed

Costs can skyrocket from there. Some Sydney Water customers have reportedly incurred personal plumbing costs as high as $16,000 thanks to wipes blocking and bursting pipes. Other customers have had their backyards covered in raw sewage when blocked pipes backed up and overflowed – again, thanks to flushable wipes.

Consumer confusion over 'flushable'

We surveyed 1679 Australians aged 18–75 in July this year to ask what they thought the word "flushable" means. 

When asked, "If a pack of disposable wet wipes is labelled as 'flushable', would you expect the wipes to not cause any blocking or clogging of the toilet?" 73% of those surveyed answered yes. 67% said that they would expect these products to disintegrate "like toilet paper". 

I've been doing this job for 30 years and wipes are now causing the worst blockages I've ever seen

Plumber Darren Clancy

For the humble consumer, as our research shows, flushable claims are confusing. Manufacturers are trumpeting words like "dispersible" and "biodegradable", while the water industry urges the public to keep all wipes out of the pipes.

Plumber Darren Clancy is blunt: "To call these flushable is insane ... they're not breaking down and in some cases not even moving out of the pipes. I've been doing this job for 30 years and wipes are now causing the worst blockages I've ever seen."

CHOICE flushable wipe test 1

We put flushable product claims to the test using an agitation device designed to provide a similar environment to the wastewater system.

We put 12 brands of wipes (11 of which were labelled as flushable and one brand that was labelled "do not flush") into the agitator along with 4-ply toilet paper, and ran the device for six hours. 

The brands we tested that were labelled as 'flushable':

  • Sorbent Clean and Fresh Wipes
  • Sorbent Flushable Wipes – Kids
  • Kleenex Cottonelle Cleansing Cloths
  • Kleenex Cottonelle Flushable Cleansing Cloths for Kids
  • Confidence Adult Wipes
  • Woolworths Select Flushable Toilet Wipes
  • Coles Bathroom and Toilet Wipes
  • White King Flushable Bathroom Wipes
  • Vagisil Feminine Flushable Wipes
  • Harpic White and Shine Flushable Toilet Wipes
  • Naty by Nature Babycare Flushable Wipes

What happened?

Within minutes the toilet paper started to break up, then disintegrated quickly leaving nothing more than milky opaque water, while all the wipes remained intact apart from some tears.

There was no sign of these products truly breaking up or even losing strength. According to the experts we spoke to, it's critical that anything that is flushed disintegrates almost immediately, otherwise it's likely to get blocked or caught in the pipes on the property where it's been flushed.

CHOICE flushable wipe test 2

Eagle-eyed consumers may have noticed there's a new type of flushable wipe in supermarkets. Slowly but surely Kimberly Clark has been swapping its Kleenex Cottonelle Cleansing Cloths for a new product, CleanRipple Flushable Wipes.

So what's the difference? The original Kleenex wipes were made from a woven, fabric-like material, while these new wipes are "paper based" and contain no synthetic fibres. This sounds like great news, but we've heard about flushable products before that don't do what they claim.

We decided to also put them to the test.

Four samples were tested in the agitator device provided by Sydney Water.

  1. Kleenex Cottonelle Flushable Cleansing Cloths (2 sheets)
  2. Quilton Gold 4-ply toilet paper (8 sheets)
  3. Kleenex CleanRipple Flushable Wipes (2 sheets)
  4. Kleenex CleanRipple Flushable Wipes (2 sheets)

The four products were tested simultaneously, each in a separate vessel, for 21 hours in the agitator device with the agitation speed set at 100rpm.

For samples 1, 2 and 3, the agitator was left running continuously for 21 hours.

For sample 4, the new product, the agitator was stopped after one minute, after five minutes and again after one hour. The sample was examined at each stage, by removing sheets from the water and testing their tensile strength and integrity (i.e. how easily they could be pulled apart by hand and how much they had broken up under agitation). After the examination at the one-hour mark, the sample was returned to the agitator which was then left running continuously for an approximate total of 21 hours.

What happened?

Sample 1: Original woven Kleenex Cottonelle Flushable Cleansing Cloths

Separated into two or three large fragments during agitation and the water remained essentially clear. On removal from the water after 21 hours, they were found to be easily pulled apart by hand into smaller fragments. However, the wipes retained sufficient structural integrity and size to still potentially snag on any obstacle or form a blockage in a sewerage system.

Sample 2: Quilton Gold 4-ply toilet paper

Disintegrated almost entirely within a few minutes. Some very small clumps remained on the agitator arm and paddle and these broke apart extremely easily when taken from the water. The water became an opaque milky colour.

Samples 3 and 4: Kleenex CleanRipple Flushable Wipes

While the new wipes did break apart under agitation much more readily and rapidly than the previous generation wipes, they broke apart much more slowly and to a much smaller degree than sample 2 (toilet paper).

Sample 3 broke apart into several tiny fragments and a few large fragments within one hour. The water became slightly milky in colour as a result. After 21 hours, the large fragments were found to break apart very easily by hand.

Sample 4 broke apart into many small fragments and a few larger fragments. The water became somewhat milkier than for sample 3. The difference in outcome between samples 3 and 4 may be attributable to the manual intervention early in the test for sample 4, resulting in its sheets breaking apart sooner. At the one-minute and five-minute marks, some fragmentation had occurred and the samples were very easily torn by hand, but essentially remained in large pieces. At the one-hour mark, further fragmentation had occurred and the samples were even easier to tear by hand, though several large pieces remained and one of the sheets remained largely intact. After 21 hours, the larger fragments were removed and found to break apart very easily by hand.

However, the larger fragments of the wipes had retained sufficient tensile strength, integrity and size to still potentially snag on an obstacle. If such sheets were flushed down a toilet regularly, it is possible that over time the fragments could form a blockage in a sewerage system.

Are Kleenex CleanRipple Wipes Flushable?

In our second test, we assessed how quickly the new paper-based Kleenex wipe broke down in our agitator. 


Based on our results, we conclude that while the Kleenex CleanRipple Flushable Wipes are likely to substantially break apart after several hours in sewerage pipes, they break apart slowly enough that the pieces retain enough tensile strength and size to reasonably pose some threat of blockage, particularly in the early stages from flushing the toilet to exiting the pipes on a consumer's own property.

It's a step in the right direction in flushability for Kimberly Clark, but it's still a stretch to call these products flushable.

It may be reasonable to say that the Kleenex CleanRipple Flushable Wipes are safer to flush than the previous version (Kleenex Cottonelle Flushable Cleansing Cloths), but if toilet paper is the standard of flushability a flushable wipe should conform to, Kleenex CleanRipple Flushable Wipes cannot be considered entirely safe to flush.

The industry responds

What manufacturers said

We contacted four manufacturers of wipes labelled as 'flushable'. 

A spokesperson for Kimberly Clark told us that their Kleenex Cottonelle Flushable Cleansing Cloths are flushable due to technology that allows them to lose strength and break up when moving through the sewerage system after flushing. Asaleo Care said its Sorbent Silky White Flushable Wipes are "a fully dispersible and biodegradable product that breaks down as it moves from household to water treatment facilities".

The Kimberly Clark spokesperson added that their products are tested for flushability using guidelines formulated by the major wipes industry associations in the US and Europe (EDANA and INDA).

At the moment there's absolutely no standard [or] agreed term on what's flushable and what disintegrates. It's just labelling

Adam Lovell, Water Services Association of Australia

Many people working in water services are critical of the EDANA/INDA guidelines because they've been developed in-house by the 'non-woven' industry – the very same industry that manufactures wipes. 

Adam Lovell, executive director of Water Services Association of Australia (WSAA), says the industry guidelines should be replaced by an independent and expert test. "At the moment there's absolutely no standard [or] agreed term on what's flushable and what disintegrates. It's just labelling."

A spokesperson for Coles, which produces a private label product, said their products were independently tested and had passed international standards. However, the spokesperson said Coles is constantly reviewing the range and is working on further improving the breakdown times of the product.

Woolworths did not respond to our enquiries.

International standard on its way

As wastewater systems around the world struggle with flushable products, there is one light at the end of the clogged-up tunnel.

An international standard for products designed to be flushed down the toilet is expected to be completed by the end of 2016. The standard will outline the tests that can be used to define if a product is able to be flushed, as well as the appropriate labelling requirements. It's designed to replace the EDANA/INDA guidelines currently used by many in the industry.

In the meantime, water utilities will continue trying to spread the word that, despite the promises on the packages and the TV ads, flushing any kind of wipe down the toilet is a bad idea.

What can be flushed down the toilet?

Lovell says the public needs more education about what can go down the toilet. "People often don't realise their toilet is not a rubbish bin. Just because it goes around the S bend doesn't mean 'out of sight out of mind'."

He says with the current lack of clarity about what is suitable to be flushed, it's best to play it safe and only flush human waste and toilet paper. "Other products are not acceptable because of their high potential to cause blockages, end up on our beaches and rivers, create sewage overflows, and increase costs for sewage treatment and maintenance."

In other words, the only things safe to flush are the '3 Ps': poo, pee and paper (toilet paper, that is).
