Are solar powered toilets the future? Well Bill Gates is betting it is and putting his money behind its development. The “Reinvent the Toilet Fair” held in Seattle this week at the Bill and Melinda Gates Foundation’s campus gave first price to Professor Michael Hoffman of the California Institute of Technology for their work on a self-contained, sun-powered toilet system that recycles water and breaks down human waste into storable energy.
The Bill and Melinda Gates Foundation has focused on developing a new type of toilet since last year as part of the push to improve health in the developing world. This is due to Bill Gates recognising that despite all the staggering medical breakthroughs and scientific advances the seemingly mundane advance of reliable sewage and reliably clean water supply was judged the greatest medical advance.
Bill Gates has constantly focused on the need for a new type of toilet as an important part of his foundation’s push to improve health in the developing world. About 2.6 billion people, or 40 percent of world’s population mostly in sub-Saharan Africa and south Asia lack access to safe sanitation and are forced to defecate in the open. Open defecation leads to sanitation problems that cause 1.5 million children under 5 to die each year, Gates said, “western style toilets are not the answer as they demand a complex sewer infrastructure and use too much water.”
As Bill Gates has realised what plumbers have always known is that fundamentally toilets have not changed since the invention of the flush toilet in 1775. For this reason Bill Gates has launched the reinvent the toilet program to inspire research into new inventions in toilet technology. “Imagine what’s possible if we continue to collaborate, stimulate new investment in this sector, and apply our ingenuity in the years ahead,” Bill Gates said at his foundation’s Seattle headquarters on Tuesday. “Many of these innovations will not only revolutionise sanitation in the developing world, but also help transform our dependence on traditional flush toilets in wealthy nations.”
Bill Gates presented prizes on Tuesday to the teams that showed the most progress on research new toilet technology. Caltech won the first prize of $100,000 for its working model of a solar powered bathroom. The Caltech model uses a solar panel to produce power for an electrochemical reactor that breaks down faecal matter and urine into hydrogen gas which can be stored in hydrogen fuel cells to provide a backup energy source for night operation or use in low sunlight conditions. The workings of the toilet are designed to be installed underground beneath a conventional looking toilet stall and urinal setup. Water recovered from the continuous process is pumped up again to provide water to flush the toilet.
The Bill and Melinda Gates Foundation is hoping many of the leading universities will work together to develop the best technologies and is aiming to get new style toilets into use in the next two to four years as they are already spending about $80 million a year on water, sanitation and hygiene issues. These are areas where it thinks it can make a marked difference in people’s lives by doing what plumbers have always provided, a hygienic toilet facility.

At Whywait Plumbing we are frequently asked about installing water filters to make the water from the tap taste better. This we understand and agree with because everyone should ensure the water they drink, shower in, cook with, prepare coffee and tea with is as pure and safe as it can possibly be.
What frequently confuses us is clients saying yes I would like a filter but it is expensive to install and maintain so I am better off buying bottles of water. This astounds us on so many levels as about 40% of bottled water is regular tap water which is 1120 times more expensive than tap water costing on average $3000 per kilolitre compared to $3.27 per kilolitre from Gold Coast City Council or $5.06 per kilolitre from Logan City Council.
Whywait Plumbing can supply and install water filters from $202.15 with the ongoing maintenance costs for replacement filters from $22.30 which is only the cost of 70 bottles of water. Bottled water is not the solution it is the problem with people paying an astounding premium for a product that is frequently full of contaminants such as arsenic, fluoride, antimony and pharmaceutical drugs.
We all need to drink more water as your body is 70% water with your blood, muscles, lungs, and brain all containing water. You need water to regulate body temperature and to provide the means for nutrients to travel to your organs and tissues. Water also helps transport oxygen to your cells, removes waste, and protects your joints and organs. Drinking too little water or losing too much water leads to dehydration. Symptoms of mild dehydration include thirst, pains in joints and muscles, lower back pain, headaches and constipation.
You lose water through urination, respiration, and by sweating, and you lose more water when you’re active than when you’re sedentary. Diuretics, medications and alcohol increase the amount of water your body loses. A strong odour from your urine, along with a yellow or amber color, may indicate that you may not be getting enough water. Lost water must be replaced by the water in the foods you eat and the beverages you drink.
Everyone has different needs on how much water they need to drink. At least twenty percent of the water you need comes from the foods you eat. The rest comes from the beverages you drink. As a general rule 8 glasses of water a day are recommended although this depends on the amount of physical activity you undertake and the climate where you live.
Water is the best choice for re-hydration because it’s cheap and has no calories or added ingredients. Sweetened soft drinks have added sugar that adds extra calories but no additional nutritional value. Sports drinks contain minerals that may help keep your electrolytes in balance, which is good for recovering after a hard gym work out, but contain sugar and calories that you may not want. Vegetable juices can be a good choice because they have vitamins and minerals your body requires. Fruit juices are okay in moderation but frequently contain high sugar levels that you do not want. Caffeinated beverages such as tea and coffee count, but too much caffeine can effect you.
Generally we all need to drink more water and the best way to ensure we drink the water our bodies require is to ensure a good quality and good tasting water supply is always readily available in our home or place of work. The best way to guarantee this is to install a water filter which is good for you and good for the environment. A water filter is a logical and cheaper alternative to bottled water as a single filter can prevent thousands of plastic water bottles from ending up in landfill and waterways further polluting our environment.
At Whywait Plumbing Services, we install, maintain and repair all types and models of water filtration systems. Whole of house or single above sink, you can trust Whywait Plumbing to provide the right solution for you and your family.

Mould is a common problem in bathrooms in South East Queensland due to our sub-tropical climate. Like most problems prevention is vital and often very simple.
Black mould on bathroom tiles
Because your bathroom and especially the shower area are the wettest areas in your home it is not uncommon to see black mould growing in the grouting and silicon sealants. Mould loves your bathroom because it is the perfect atmosphere to create the ideal conditions for mould growth in the cracks and gaps in the tiling. Consequently black mould grows in behind and through the grout joints on the tiles. As can be seen on the photo on the right black mould loves getting in behind the silicon seal on the internal corners whether it be the wall or the floor.
The most common area to find mould is in your shower where it is nourished by your body oils, shampoo and soap residue that are left behind every time the shower is used.
Poor air circulation actively assists mould growth as the warmth and moisture created in the enclosed area of a shower offer further ideal conditions for mould growth in the dark areas of the shower around the internal corners and the shower floor drain. Poor air circulation is easily resolved by ensuring you install a good quality bathroom extraction fan above the shower that turns on automatically to remove all of the steam and water particles while you are using the shower.
If you are suffering from black mould growth in your bathroom then Whywait Plumbing recommend that you act early to remove it before permanent stains are created. To get rid of early mould growth the best solution is to use a paste of baking soda and vinegar. Simply mix one cup of water with white vinegar and water to create a smooth paste. Then apply the paste to the areas where mould is growing, gently scrubing it with an old soft tooth brush until it starts to turn white and then leave it. After half an hour rinse off all the paste using your shower spray and if any mould still is visible you will need to repeat applying the paste and scrubbing it until all of the mould has disappeared.
The paste above will work perfectly on mould that is detected and removed early but if you have a real infestation then use a 50/50 mix of water and bleach in a spray bottle. Ensure you have adequate ventilation in the bathroom before you begin lightly spraying the mould. Once again spray then leave for half an hour, rinse off and spray again until all of the mould has disappeared.
Mould behind the silicon sealant on the internal corners will require more thorough work. First use a utility knife to scrape off all of the silicon and you may need to use a blade to scrape the remnants clear off the tiles. Once all of the silicon has been removed spray the mould with the 50/50 bleach until it has all disappeared. Once the mould has gone rinse the area clean and dry it thoroughly with a hot air dryer to ensure there is no moisture trapped in the open joint. Finally reapply a good quality mould resistant silicon to the joint which is specifically designed for high moisture areas.
If mould reappears within a few weeks then you may have problems with leaking pipes or fittings that require a thorough investigation by Whywait Plumbing to ensure you are not damaging internal frames and wall linings.
Remember mould is only a sympton of a bigger problem and ignoring will not make it disappear. If in any doubt call Whywait Plumbing for advice on how to deal with mould in your bathroom.

Traditionally toilets flushed 11 litres or 3 gallons of water every time they were flushed with the water all flowing along through a drainage system that was designed for large flows of water. Unless a drain was broken or roots entered the drain it was not common for a drain to block. That was of course until the advent of reduced flow dual flush toilets.
Now that toilet only flushes 4.5 litres of water on a full flush and 3 litres of water on a half flush into the drainage system. Coupled with reduced flows from every other tap this has produced a situation where drains designed for large flows of water have had the water flow reduced by 60% in most cases.
The increase in blocked drains due to the reduced water flows has been a big boost for plumbing companies such as Whywait Plumbing with drains clogging up for no other reason than lack of water flow. Often there is a dual problem of incorrect fall on the drain which creates high spots in the pipe leading to the drain becoming clogged at that point.
In Singapore scientists at Nanyang Technological University (NTU) have invented a new toilet system that will reduce the amount of water needed for flushing by up to 90 per cent compared to current toilet systems. Dubbed the No-Mix Vacuum Toilet, it has two chambers that separate the liquid and solid wastes. Using vacuum suction technology, similar to those used in aircraft toilets it uses 0.2 litres of water for urine and 1.0 litres of water for solids.
The No-Mix Vacuum Toilet installed in a standard public toilet which is flushed 100 times a day, is expected to save 160000 litres of water a year. The NTU scientists are now looking to carry out trials by installing the toilet prototypes in two NTU public toilet facilities. This trial is important due to the issues that plumbers are already aware of with the drains blocking at 4.5/3 litre flushes so a 1.0/0.2 litre flush is expected to exacerbate this problem in existing buildings.
The No-Mix Vacuum Toilet with it’s two chambers that separate the liquid and solid wastes also will turn human waste into electricity and fertilisers. The No-Mix Vacuum Toilet will divert the liquid waste to a processing facility where components used for fertilisers such as nitrogen, phosphorus and potassium can be recovered. At the same time, the solid waste will be sent to a bioreactor where it will be digested to release bio-gas which contains methane. Methane is odourless and can be used to replace natural gas used in stoves for cooking. Methane can also be converted to electricity if used to fuel power plants or fuel cells. ‘Grey water’ (used water from the laundry, shower and kitchen sink) can be released back into the drainage systems without further need for complex waste water treatment, while leftover food wastes can be sent either to the bioreactors or turned into compost and mixed with soil, resulting in a complete recovery of resources.
The No-Mix Vacuum Toilet uses will be limited in traditional buildings but will be useful for eco resorts, new housing estates, hotels, resorts, and especially communities not linked to the main sewerage system or unable to be connected and so require their own sewerage facilities.
Associate Professor Wang Jing-Yuan, Director of the Residues and Resource Reclamation Centre (R3C) at NTU who is leading the research project, said that their ultimate aim is not only for the new toilet system to save water, but to have a complete recovery of resources so that none will be wasted in resource-scarce Singapore. “Having the human waste separated at source and processed on-site would lower costs needed in recovering resources, as treating mixed waste is energy intensive and not cost-effective,” Prof Wang said. “With our innovative toilet system, we can use simpler and cheaper methods of harvesting the useful chemicals and even produce fuel and energy from waste.”
The development of a No-Mix Vacuum Toilet has great potential for use on the Gold Coast in the development of tourist facilities in environmentally sensative areas where traditional sewerage systems cannot be installed.

For as long as I can remember, there has been a debate about whether we need council plumbing inspectors. After all, there is no such thing as council building inspectors anymore or electrical or gas inspectors. Plumbers in Queensland are the only licensed trade still legally obligated to have work inspected by the local council plumbing inspector.
In reality, Queensland is the only state in Australia still with council plumbing inspectors. All other states now only have audits of work undertaken which depend on the honesty and integrity of the plumbers lodging the correct paperwork.
With the amendments to the Plumbing and Drainage Act 2002 coming into effect in Queensland in November, I believe we will have the best of all worlds. We will still have council plumbing inspectors, but their role will change to allow them to concentrate on ensuring new buildings are fully compliant, plus undertaking much more audit work.
The most significant improvement will be that much of the work on existing buildings will become notifiable, meaning that it can be undertaken without a council permit or inspection. This will reduce red tape and fees dramatically, plus speed up the ability of work being launched, as there will be no waiting of 2-4 weeks for applications to be processed and approved.
Of course, these improvements will only benefit plumbing companies that already obey the law and ensure they undertake work in a compliant manner. It will make no difference to those plumbers who have refused to comply with the law and lodge no paperwork. Likewise, it will make no difference to those without plumbing licenses who undertake plumbing work.
In recent years I have undertaken projects in Asia based in Singapore, where we have an office specialising in advanced hot water systems and sustainability products such as waterless urinals. Having returned from Singapore this week, I am reminded why we need plumbing inspectors because there is no sense in having world class laws and regulations when there are no audits or inspections of the work to ensure the plumbing systems are compliant.
Above is a photo of a 25-litre hot water service installation in a bathroom in an apartment worth around $1.75 million in downtown Singapore. This would have been installed as part of the building construction and is impossible to maintain without completely disconnecting as the element and thermostat face into the wall. Even more concerning is that the relief valve does not discharge into a tundish but onto the floor.
This scenario is not unusual in Singapore, as there are no plumbing inspections. Although similar to Australia, buildings are constructed to a cost, not to a standard but at least in Queensland, with council plumbing inspectors undertaking inspections at all stages of a building’s construction, building owners can be assured that the plumbing and drainage installations are compliant and of a high standard.
On the Gold Coast, it is to be hoped that the GCCC plumbing inspectors embrace the reforms and improve their track record for “interpretations” of both the legislation and the Australian standards.
Ultimately local council plumbing inspectors are a critical part of the system in protecting public health and safety, and a well-run council plumbing inspectors department benefits the community as a whole.

Gold Coast homeowners are increasingly subjected to allegedly “free compliance audits” by Gold Coast City Council plumbing inspectors. To justify their jobs in a depressed market with almost nil construction activity, Gold Coast City Council plumbing inspectors act like desperate door-to-door salesmen knocking on the doors of homeowners who have upgraded hot water systems. There is no legislative requirement for these audits to occur, and the homeowner does not need to allow them to enter their home.
To fill in time and justify their jobs, Gold Coast City Council plumbing inspectors are undertaking “audits” that are not requested and are unannounced. The plumbing inspectors are knocking on the door and stating they are there to inspect the hot water service. Legally they can assess the work if invited to do so by you. No Gold Coast plumber is asking them to evaluate the work, as none of us sees any value in doing so. Neither Gold Coast City Council nor its plumbing inspectors take any risk or responsibility, so their inspection is of no real value except to justify their jobs.
If Gold Coast City Council plumbing inspectors arrive unannounced at your door, he has no right of entry. He may request access by your invitation to inspect work that pertains to the form 4 plumbing contractors are legally obliged to lodge, but that is the absolute limit. If you refuse him entry, then he must immediately depart.
Unfortunately, the plumbing inspectors are loose with the truth and make out that they are legally obligated to undertake this audit. They do not inform homeowners that it is optional and not a legislative requirement.
The individual plumbing inspectors are not to blame for these events but are forced to do so as they work in an appalling atmosphere at Gold Coast City Council. It has been common knowledge within the plumbing industry for many years that the Gold Coast City Council plumbing inspectors are a deeply troubled organisation with bullying, abuse of power, nepotism, cronyism and double standards a daily occurrence.
Several clients of Whywait Plumbing that have received these unexpected visits were shocked when we phoned to say their hot water service we installed six months ago has had a defect notice issued. In every instant, as long as Whywait Plumbing receives the defect notice, we undertake the “repairs”, which invariably are that the tempering valve legally required to deliver hot water at 50 degrees is over temperature. To date, every home we have returned to is between 1-3 degrees over temperature. To see more information on the requirements of tempering valves and your obligations, click here.
Many of our clients have told us that they do not want the plumbing inspectors returning to their homes to re-audit. This we have conveyed via email to Gold Coast City Council plumbing inspectors on behalf of our clients. As a result, we had a phone call from the Gold Coast City Council Plumbing & Drainage Supervisor, Brian Till, recently, who informed us we should be encouraging our clients to have the re-audit undertaken; otherwise, we will remain responsible for the defects despite our notifying Gold Coast City Council that rectification work has been conducted.
Furthermore, Brian Till advised that the property will have registered against the title that there are outstanding plumbing defects which can have severe financial repercussions if you wish to sell your home.
If you get an unexpected knock on the door from a Gold Coast City Council plumbing inspector, we recommend you decline to allow them entry to your home. However, declining access does not affect you as they walk away, and the file is closed.
However, suppose you have had a defect notice issued. In that case, we recommend allowing a re-audit at a time that is suitable for you to ensure no defects are registered against your property. If you desire, we will attend at no cost to reassure you and ensure that due process is complied with.
