Zeroflush waterless urinals installed at Brisbane International Airport
ZeroFlush Waterless urinals supplied and installed by Whywait Plumbing are precisely what they sound like. Instead of using water to flush away the urine, like traditional urinals which waste anywhere up to 25 litres of water every time they flush. ZeroFlush waterless urinals utilise gravity, putting urine through an odour barrier or one-way valve system which eliminates 100% of the water from a conventional flushing process.
Replacing a water flushing urinal with a ZeroFlush waterless model can save an average of 152000 litres annually per urinal. There’s one urinal for every three toilets in non-residential properties, which together account for more than a quarter of Australia’s water consumption.
The supply of water to commercial office buildings, shopping centres, educational facilities and hotels utilises a substantial amount of energy. The simple act of installing ZeroFlush waterless urinals and the disconnection of urinals from a buildings water reticulation system can reduce by 50% a building’s greenhouse gas emissions.
Throughout Australia, water charges continue to increase annually. The advent of sewerage discharge factor charges based on the amount of water consumed is increasing in popularity. These charges alone require reductions in water consumption to avoid substantial annual increases. For commercial property managers, this means they must budget for paying for water coming into the building and also going out via the sewage system. This means the installation of ZeroFlush urinals will not only aid with sustainability but reduce water and energy costs.
The urban myth that waterless urinals are unhygienic and stink is a myth perpetuated by opponents of waterless urinals that has no foundation in fact. A recent study by th
e Shanghai Environment Project Design Institute once again proved that waterless urinals contain five times fewer bacteria than water flushing urinals. Bacteria and germs from water flushing urinals are created by airborne fecal matter that is reproduced when the urinal flushes water. The combination of water moisture with the fecal matter creates the perfect environment for bacteria to grow and flourish. As waterless urinals don’t flush water every time they have been used the opportunity for bacterial and germ contamination becomes very remote.
The real reason most male bathroom facilities have putrid odours is triggered by the bacteria created from airborne fecal matter and water moisture. Urine by itself has a very soft odour but combined with the water flushing urinals spraying of water particles it can quickly create odours over the entire bathroom facility.
ZeroFlush waterless urinals are a guaranteed path to reducing water and energy consumption plus greenhouse gas emissions in any non-residential commercial building. Installing them will always help water and energy sustainability.
Plumbing innovations have always been the norm in the plumbing industry. Innovation is change and is always about better ways of doing the same thing.
When I started my apprenticeship the clearing of a blocked drain started using a plunger and was at least a two-man job using 1m long drainage rods. The rods were screwed together and manually pushed slowly down the drain until we hit the blockage. Clearing drains this way frequently took 3-4 hours.
Plumbing innovations mean that we now clear a blocked drain with state of the art high-pressure jetrodding technology that was unknown 20 years ago.
Innovation is always about change, but at Whywait Plumbing we have always been at the forefront of plumbing innovations. We have always lead change as Gold Coast plumbers from the purchase of our first high-pressure water jetting unit in 1992 or installing vehicle tracking systems or introducing guaranteed upfront pricing in 1999.
What we always considered was developing and improving our way of solving your plumbing problems is now referred to as disruptive innovation. I agree disruptive innovation is the new term in business in the 21st century. But it’s not new it’s just a new way of talking about improving our methods and practices using the latest technology.
Change is the norm, but it just appears to be frantic to an outside observer with online banking, online shopping, online flight bookings and so the list goes on. At least with plumbing, it can’t be done online except for those DIY enthusiasts who believe Google Plumbing has all the answers.
The level of disruption through plumbing innovations has impacted all plumbing installation and maintenance has been significant starting with:
- Increasing use of prefabrication of bathroom and kitchen modules off-site where the plumbing is all undertaken in a factory, transported to the site and connected up to a water and drainage connection.
- Continual advances in sustainability with the advent of low flow toilets, low flow taps, waterless urinals and recirculated hot water.
- Advances in energy efficient products with heat pump hot water units, solar hot water, instant hot water and underfloor heating.
- All of the different materials we now use in the pipework, relining of existing pipework, CCTV cameras to inspect pipes and pipe jointing methods where welding is now obsolete.
- Excavation methods with advanced technologies in hydro excavation and tracking and locating of underground services.
The ongoing changes in technology in the plumbing industry are disruptive if not embraced. I agree that plumbing innovations cause a significant difference in how we undertake to solve plumbing problems and how the plumbers at Whywait work now.
Ultimately plumbing continues to be about protecting the health and safety of the community for now and the future to ensure we have good quality water and sewer systems in our buildings.
ZeroFlush waterless urinals are an increasingly widespread investment being made by architects, hydraulic engineers, facilities managers and building owners throughout Australia because they help conserve water.
Here at Whywait Plumbing, we concur that there are conflicting arguments about the amount of money they save. ZeroFlush waterless urinals do operate without flushing any water, so they will always save water first and foremost. But when making a case for their installation and the investment in maintaining and operating them the best evidence is they are environmentally and sustainably superior to every water flushing urinal.
Installation of ZeroFlush waterless urinals as a corporate responsibility effort should always be a consideration, but here at Whywait Plumbing our experience with ZeroFlush enables us to give you a performance guarantee.
On current Gold Coast Water charges we can guarantee installation of ZeroFlush waterless urinals will reduce your water and sewer discharge costs.
Contact us at Whywait Plumbing now to discuss how you can benefit by installing ZeroFlush waterless urinals as we can guarantee the following:
- the reduced capital cost to install as no expensive electronic water flushing systems are required
- reduced maintenance costs with no water reticulation valves to maintain
- simple and easy cleaning procedures with our natural enzyme cleaning products
- reduction in blocked drains and drainage traps
- all products used in the manufacture and maintenance of ZeroFlush waterless urinals are environmentally sustainable
Determining exactly how much water a ZeroFlush waterless urinal keeps from the Gold Coast Water sewer system is somewhat complicated. The number depends on a variety of arguable variables, such as the amount of water that a water flushing urinal would use, the number of people using the urinal and how often those people will use it.
A single water flushing urinal can use anywhere from 50,000 litres to 180,000 litres of water every year. Once again this is based on multiple variables such as the size of the building, the number of male employees and how many times they use the urinal each day. A building such as a factory with one bathroom facility, three ZeroFlush waterless urinals and 120 male employees, would save approximately 900,000 litres of water each year.
Calculating the payback period for installing ZeroFlush waterless urinals can be a complicated process. Using the average of $9 per 1,000 litres of water from Gold Coast Water and the example of an office with four men working in it, we can come up with some estimates.
Let’s say each man flushes a urinal 2,000 times per year or about 5.5 times per day, meaning that the four men flush the toilet 4,000 times a year in the office. With an older, water flushing urinal using 15 litres per flush will use 60.000 litres, costing about $540 every year just for water.
Ultimately, ZeroFlush waterless urinals save more water than money, but we guarantee that they are still worth the investment in sustainability.
Desert eco adapt cartridge illegally installed in ZeroFlush waterless urinals
Yet again we have come across the installation of the Desert Eco Adapt cartridge illegally installed in ZeroFlush waterless urinals at Queensland Tennis Centre.
We immediately informed the facility manager that these products known as Desert Eco Adapt cartridges were a non-conforming product in a ZeroFlush waterless urinal. We further told Tennis Queensland of our responsibilities concerning reporting non-conforming products to the QBCC. This is due to recent amendments to the Queensland Building and Construction Act 1991, the Plumbing and Drainage Act 2002, and the Building Act 1975 concerning non-conforming building products. These amendments came into effect on 1 November 2017. These amendments were effected through the passage and proclamation of the Building and Construction Legislation (Non-conforming Building Products – Chain of Responsibility and Other Matters) Amendment Act 2017.
Tennis Queensland immediately requested that we remove all of the Desert Eco Adapt cartridges and replace them with the compliant ZeroFlush EnviroSeal operating system.
Removal of the Desert eco adapt cartridge at Queensland Tennis Centre
Before removing the Desert Eco Adapt cartridges, we undertook a thorough inspection of the ZeroFlush urinals. This confirmed what had been reported that all were emitting sewer odours as they were a sloppy fit into the ZeroFlush stainless steel rim. The cartridges literally slipped up and out as we removed them as they were not sealing to the stainless steel rim on the housing.
As can be seen in the photo on the left despite being relatively new, there are urine stains on the Desert Eco Adapt cartridge as the rubber seal is not designed to fit ZeroFlush urinals and was not only allowing sewer odours to be emitted, but urine was leaking down the side of the cartridge rather than going through the waste outlet drain.
These issues can be further seen by the stains on stainless steel rim in the photo to the right. These stainless steel rims were all spotlessly clean when we serviced the urinals in December.
All of the non-conforming Desert Eco Adapt cartridges were removed, and the EnviroSeal operating systems were reinstalled along with new BioPur Wonder Wizard Tab kits after cleaning and flushing of the drains.
To the left is a photo of the five ZeroFlush ZF201 urinals after scheduled servicing and with the EnviroSeal operating systems reinstalled.
The EnviroSeal operating systems are a WaterMark approved system for ZeroFlush waterless urinals only. They were tested extensively by IAPMO R&T laboratory at 5001 East Philadelphia Street, Ontario, California 91761-2816 USA from 24/03/14 – 04/04/14. The EnviroSeal operating systems was then given WaterMark certification in Australia on 17/06/14, and it was renewed for a further three years on 07/08/15.
We were informed by Tennis Queensland’s facility manager that the Desert Eco Adapt cartridge was installed as a trial as they are significantly cheaper than the genuine ZeroFlush parts.
It was concerning that the facility manager also informed us that a licensed plumber had installed the Desert cartridges. It is an offence under the Standard Plumbing and Drainage Regulation 2003, Part 4 Product Certification for a licensed plumber to install non-certified and non WaterMarked products as per the clauses on the right.
Despite claims made by the Desert Eco Systems Company at http://www.desert.com.au/products/eco-adapt-advanced/ the facts are that their cartridges have no WaterMark certification for any urinal in Australia other than their own Desert No-Flush Urinal.
All plumbing products installed in buildings in Queensland have been required to have WaterMark certification since 2003 under the Plumbing and Drainage Act 2002 and the Standard Plumbing and Drainage Regulation 2003.
The Watermark Certification scheme is administered at a national level by the Australian Building Codes Board (ABCB). The requirements for WaterMark certification is specified in the Plumbing and Drainage Act 2002.
Building and Construction Legislation (Non-conforming Building Products – Chain of Responsibility and Other Matters) Amendment Act 2017
Under the primary duty of care of the new laws being the Building and Construction Legislation (Non-conforming Building Products – Chain of Responsibility and Other Matters) Amendment Act 2017, it is an offence under the Act to supply plumbing products in Queensland that doesn’t have WaterMark certification as these products do not meet the relevant regulatory provisions.
This change is designed to reduce the likelihood of non-conforming plumbing products being installed in buildings in Queensland.
More information on the Watermark certification system, including a list of certified products and information on the certification process, can be obtained from the ABCB website here: http://abcb.gov.au/ProductCertification/WaterMark-Certification-Scheme
Despite being a non-conforming product and illegal to install it is our opinion that the Desert Eco Adapt cartridge is an inferior product compared to the EnviroSeal system that has been designed, tested and certified only to be used on ZeroFlush waterless urinals.
The Desert cartridge was a sloppy fit into the ZeroFlush stainless steel rim that created sewer odour emissions that could have repercussions with members of the public that have respiratory conditions. This potentially exposes building owners and their employees to legal liabilities for having installed a non-conforming substitute product.
The Desert Eco Systems Company has a long history of substituting products and making claims that their products are a conforming product when they are not and never have been. Product substitution where the product has not been tested, and WaterMark certified for the product it is substituting is an offence under the Building and Construction Legislation (Non-conforming Building Products – Chain of Responsibility and Other Matters) Amendment Act 2017.
Everyone in the chain of responsibility needs to be aware that they are breaking the law if they authorise, instruct or install Desert Eco Adapt cartridges in any urinal that it has no WaterMark for. Under Australian consumer laws if you have installed a Desert Eco Adapt cartridge in any waterless urinal other than the Desert No Flush urinal, based on the dubious claims made to you by representatives of Desert Eco System Company, then you are not only entitled to a refund of all your money but also compensation to pay for your waterless urinals being returned to a legally compliant status as per your waterless urinals WaterMark certification.
If you have the Desert Eco Adapt cartridge installed in your urinals, then its 99% guaranteed its a non-compliant installation so contact Whywait Plumbing on (07) 5580 4311 today to organise a site audit of your urinals to ensure they are legally compliant.
Whywait Plumbing has, since 2004, been the service agent for ZeroFlush waterless urinals throughout Australia. Before that, we had, and continue to have extensive experience with installing and maintaining both the Falcon waterless urinal and the Uridan waterless urinal. As a consequence of our long and extensive experience, Whywait Plumbing is acknowledged as an expert on the installation, servicing, and maintenance of waterless urinals.
In 2006, as water shortages and drought gripped many Australian cities, so-called water sustainability companies sprung up everywhere. As always, this was to take advantage of government subsidies and offer simplistic answers to what were in reality, complex problems with water requiring expert plumbing knowledge.
One of these companies was Desert Eco who claimed they could give you a pill called the Desert urinal cube to throw into your water flushing urinal, turn off the water supply and turn it into a waterless urinal.
This, of course, was illegal then and remains unlawful now. In fact, in 2010 amendments to AS/NZS 3500.2-2003 had to be introduced to combat the damage that was occurring in urinals everywhere. These amendments clarified the requirements for the use of waterless urinals and effectively banned the practice of converting water flushing urinals to waterless urinals.
In recent years Desert Eco have renamed themselves as Desert, but they are still the same company. They continue making extravagant claims that the Desert urinal cube with a small amount of water dispersed over it every day will activate the cube releasing slowly dissolving beneficial microbes over several weeks that will break down organic matter in the drain and remove unpleasant odours. The worrying thing about this claim is that there is no organic matter in a urinal drain as urine is composed of water and salts.
Whywait Plumbing continues to see the damage that Desert Eco create with their outright lies that they have reduced high maintenance costs with their new EcoAdapt Advanced package and it can be applied to any existing or new waterless urinal. They even illegally claim that their unique Desert EcoAdapt urinal cartridge is reusable and fits nearly all waterless urinal brands.
The installation of the Desert EcoAdapt urinal cartridge in a ZeroFlush waterless urinal has once again caused problems with foul odours being emitted from the urinal and the urinal being slow to drain.
Using the Desert EcoAdapt urinal cartridge for waterless urinal servicing is entirely illegal and non-compliant on every waterless urinal and water flushing urinal in Australia.
The only urinal in Australia that can legally use the Desert EcoAdapt urinal cartridge is their own waterless Desert No Flush urinal which does have a compliant WaterMark certificate to ATS 5200.459:2004 Technical Specification for plumbing and drainage products Part 459: Waterless urinals—Wall-hung.
The use of the Desert EcoAdapt urinal cartridge in a ZeroFlush waterless urinal is illegal and non-compliant as it is in all waterless urinals. Using the Desert EcoAdapt Advanced package will leave you open to possible legal action from plumbing authorities, manufacturers and most of all from the general public for a breach of workplace, health and safety regulations.
Waterless urinals are much more than water conservation
Commercial building owners ten years ago were predominantly concerned with maintaining a clean public toilet facility, and little or no thought was given to sustainability. It was a known operational fact that especially for businesses that had a high movement of people that the cleanliness of their toilet facilities boosted the success of that business.

According to a recent industry survey, more than 75% of adults would avoid a restaurant, hotel or shopping centre if they encountered dirty toilets. A clean and hygienic bathroom is absolutely critical for any building. In many ways, the toilet facilities act as an ambassador and speak volumes about the overall management of a building.
In recent years it has become increasingly clear that building managers must also strive for sustainability. As such, businesses and building owners and managers strive to incorporate products that are not only sustainable but are visibly environmentally friendly.
As one of the most visible areas of any building, the toilet facilities are the source of more complaints than any other operational aspect of a building. Unfortunately, public toilet facilities are one of the most challenging areas in a building to keep clean. Sustainable product choices in the toilets contribute to a cleaner, more hygienic experience and are also better for the environment.
An area that Whywait Plumbing has not only pioneered but continued to develop a product in is waterless urinals. Waterless urinals such as ZeroFlush waterless urinals are only mentioned in an environmental context, where both the immense water savings of up to 152000 litres and more per urinal, per year and carbon emissions reduction of up to 320kg per urinal, per year are cited.
ZeroFlush waterless urinals reduce odours
There is a common misconception that waterless urinals are not as hygienic as their flush urinal counterparts. However, waterless urinal systems actually reduce odours and contribute to a cleaner, more sanitary public toilet facility. A few facts demonstrate why:
- Urine is virtually odourless.
- Urine odour primarily results from the reaction of urine with water and air.
- Without water, the urinal quickly dries between uses and produces no detectable odour.
Waterless urinals reduce disease-carrying microorganisms
Dr Michael Hoffman, professor of environmental science and dean of graduate studies at the California Institute of Technology, concluded in an independent study that, “The dual barrier system provided in waterless urinals are predicted to be 500 times more effective against the back migration of sewer gases as compared to conventional P-trap water barriers.”
Bacteria and viruses thrive on moist surfaces, and the wet surface of a water flushing urinal is a breeding ground for their growth. Flushing doesn’t kill bacteria and viruses. Worse, the flush creates a mist that spreads bacteria and viruses to every surface in the toilet facility.
Dr Charles Gerba, professor of environmental microbiology at the University of Arizona, explains, “Waterless urinals offer a major improvement in public sanitation. Flushing is eliminated, which greatly reduces the almost continuous production of microbial aerosols, and the surface and sides of urinals are drier, which reduces the survival of human disease-carrying microorganisms and prevents their growth.”
According to the Journal of Infection Control, bacteria such as those that cause the influenza virus can thrive and linger on surfaces for up to 72 hours. As a result, water flushing urinals contain more bacteria and microorganisms than waterless urinals. The waterless feature of waterless urinals can help reduce the risk of cross-contamination because users are not required to touch a flushing device that may harbour bacteria.
ZeroFlush waterless urinals ensure a user-friendly experience
Waterless urinals require minimum maintenance to ensure a clean, hygienic, sustainable, user-friendly experience. The ZeroFlush waterless urinal installed by Whywait Plumbing requires like all urinals periodic maintenance. At the same time, daily it is merely a matter of a simple spray of the urinal with Spray and Go a mild cleaner that requires no wiping clean as you would with a flush urinal. Because there’s no water, there will be no limescale or calcite build-up, which makes cleaning fast and easy.
With ZeroFlush waterless urinals, building owners and managers can be assured that their public toilet facilities will be sustainable, cleaner, and the experience of their clients will be both hands-free and hygienic.
