denecessary

As many of you may be aware, my contract with Queensland Urban Utilities has not been renewed.

My last day will be the 31 December 2012.


I commenced my career at Queensland Urban Utilities as an Audit and Compliance Officer, checking on safety and quality of water and sewerage construction projects including sewer main upgrades and water main pipe bursting. It was not long before I was seconded into the Contract Management of the construction of an additional overflow channel for the Luggage Point Sewage Treatment Plant.  

I really enjoyed the opportunity to manage the contracts for upgrades to regional lagoons, in some cases from procurement right through to construction. I also appreciate having the opportunity to be involved in a team working strategically to embed ecological and business sustainability principles into Queensland Urban Utilities’ procurement processes.

In the short term, I will be looking for another opportunity somewhere in the local, Australian Water industry.  I would be grateful, if anyone has some suggestions.


In the longer term, I shall be pursuing opportunities in International Development Assistance for water and sanitation in developing communities.


I will continue to seek support from Queensland Urban Utilities to assist reinventing the toilet and/or to work on local projects to improve access to toilets.


I have really enjoyed working at Queensland Urban Utilities. 

I give a shit! Do you?

The WTD is a day to raise awareness of how much there still is to do to ensure that billions of people around the globe have access to good sanitation. 

However, World Toilet Day is also a day to celebrate the good work that is being done and what has been achieved already. One way to contribute with the World Toilet Day is to share your experiences from the last year.

So the question is: Since the last World Toilet Day in 2011, what experience, activity or event that you were part of, etc that signals that progress is happening stands out for you?

If you have something to share, please send up to 250 words to P.Bongartz@ids.ac.uk and, if possible, a photo (separately in a jpg file) to go along with what you have written about. 

The responses will be compiled and posted them on the website on World Toilet Day.

Deadline: Tuesday, 13th November

Toilet 2.0 - the next Generation

In recent years we have seen a transition from analogue radio and television to digital services.

Smarter telephone technologies including video and net based applications are complementing the traditional voice down a copper wire.

Automotive companies are starting to roll out electric vehicles to replace internal combustion engine technologies.

These processes are transitional.

Prototypes were developed.  They begin as pilot projects, to prove the concept.

This is exactly what is proposed for developing Toilet 2.0 technologies.



The rationale for source segregation is to encourage nutrient recovery and reduce to costs and environmental impacts of the tradition method of aggregating urine and feaces with vast quantities of flush water, grey water and trade waste.

We need to identify pilot projects, to demonstrate the concepts of source separation of urine and feaces.

We need to develop the supporting processes, the institutional arrangements and encourage the social acceptance of the paradigm shift.

We need to develop trade waste policies and charges that incentivate and support source segregation.

Using traditional toilet technologies, there is a peak load of nitrogen, phosphorus that coincides with a hydraulic peak load, every morning and evening.

We need business models and a business case that demonstrates the value of source segregation.  There is a potential for delaying large capital investment for infrastructure upgrades by reducing the peak loads.  There are opportunities to reduce or avoid the operational costs at sewage treatment plants by reducing the need for energy intensive, biological and chemical processes for removing nitrogen and phosphorus.

The Toilet2.0 technologies provide an opportunity to lower the costs of delivery of sewage treatment services and increase the opportunities for resources recovery, energy efficiency, water efficiency and better environmental outcomes.

If Toilet2.0 technologies can be developed and demonstrated in my community, there is a huge market potential to meet the needs of 2.6 billion people who lack access to any form of toilet.

Toilet 2.0

Today I had the pleasure of talking about the exciting potential for the next generation of Toilet technologies, to my colleagues at work.  I work for a water and sewage treatment utility.


Our current Toilets are connected to a grid in a way that is analogous to a landline telephone connected to copper wires, telephone exchanges and data centres.  The toilets in my community, are dependent on a reliable water supply, sewer pumping stations and sewage treatment plants.  The floods in Brisbane in January 2011 and the subsequent earthquake in Christchurch and the Tsunami in Japan, demonstrated the vulnerability of these systems.

My ambition (which is shared by many others) is to see the development of the next generation of toilet which are "off the grid".


The imperative is providing services for 2.6 billion people in developing communities, who lack a sustainable place to poo, wee and/or change sanitary pads.


In the developed world, the cost of living pressures, the cost of water, electricity and the cost of running sewer networks and sewage treatment treatment plants are all on the radar.


The regulating authorities in the Qld State Government have capped the price one can charge for water and sewage treatment.  The price of raw water is under review.  All indications are, that Water Authorities are going to be under significant political pressure to reduce the cost of delivery of services.


Climate change, peak oil, peak phosphorus are all driving the need for change, to reduce the energy intensity of water and sewage treatment services and recover energy, nutrients and/or water from the process.


There arises a need for a next generation of toilets.  Yet the toilet is really just a user interface.  We need a whole new "back end" to the process.  


The first distinction between 1.0 series toilets and the 2.0 series is the separation of one's Number Ones from one's Number twos.

Our Number One's a choc full of nutrients: Nitrogen, Phosphorus, Potassium....


One person's urine contains enough nutrients to grow enough cereal to feed one person.


In my community, our number twos are not nearly as interesting (or valuable).  We tend to eat too much processed food.  However, the poo from a Vegetarian could be highly valuable. The dry solids can be combusted, digested or under go pyrolysis to generate electricity, heat, light, gas or compost.


The process engineering aspects of Toilet 2.0 are really very straight forward.


The complexity lies in the social engineering.  Some of the greatest resistance to change comes from within the water/sewage treatment industry.  Today I had the opportunity to make a case for change.


I was hoping someone would say: "It cannot be done!".  I was hoping someone might say: " You're crazy!"


However, the questions and discussions were actually intelligent and provocative.  There maybe some who want to work on intermediate technologies.  Perhaps there is still a need for Toilet 1.1.   


My ambitions are still quite modest.  Toilet 2.0 is not a silver bullet.  Toilet 2.0 is the next generation of toilets.  It is time to get Toilet 2.0 out of the laboratories and into your lavatories.

why are we walking for water (& sanitation)

Some friends & acquaintances are attempting to organise a Walk.

They are trying to plan a route to or from a place of political significance or media interest in Brisbane. The folks who enforce the Peaceful Assembly Act 1992 at Brisbane City Council are making this nigh impossible.

They are trying gather friends, high-profile supporters and politicians to join the walk........and they need your help.

The tentative date for the alleged Brisbane Walks For Water is Friday the 23 March, 2012 at noon (12:00 gmt +10).

They shall rendezvous at Reddacliffe Place and march around the CBD if they can get permission to do so.

They don't have public liability insurance. They have not filled out countless forms or got all the necessary approvals. They just want to organise a walk. How hard can it be?

It is a walk for water & sanitation.

Why is the world walking for water and sanitation in March 2012?

Do you even know what the hell sanitation is?

Let's start with some statistics:

• One in eight people in the world do not have access to safe drinking water.
• One in three people don’t have access to a private clean toilet.

Women and children walk on average six kilometres every day to fetch water for their basic needs. They often walk to unprotected water sources, such as rivers or muddy dugouts, and the average weight of water they carry is 20kg. ( UNDP, Human Development Report, 2006)

2.6 billion people still live without a clean and safe toilet ( UNICEF/WHO Joint Monitoring Report, 2010). Instead, they have only a roadside, bucket or plastic bag to use. This is humiliating and also often leads to water contamination and the spreading of diarrhoeal diseases such as dysentery and cholera.

Women and girls are especially affected by poor sanitation access. They risk being sexually assaulted when using latrines in remote locations or walking to fields to defecate.

4,000 children die every day from diarrhoea caused by unclean water and unsafe sanitation ( WHO, Safer Water, Better Health, 2008).

Diarrhoeal diseases are the biggest killer of young children in Africa, killing

more than HIV/AIDS, malaria and measles combined.

This lack of access to clean water and sanitation impacts severely on health, education and income.

It’s time for change. We are not talking about a change of Government.

The World Walks for Water and Sanitation 2012 is a global event taking place around World Water Day, from 17-25 March 2012. Thousands of people across the world will walk together to demand an end to the water and sanitation crisis. The walks will build on the success of the World’s Longest Toilet Queue in 2010 and the World Walks for Water campaign in 2011. Last year, over 350,000 people in more than 75 different countries walked together to demand that politicians keep their promises and step up their efforts to protect the right to sanitation and water for all.

Because of these global actions, governments are beginning to take notice, promises have

been made, and there has been progress both internationally and within countries. This has

encouraged hundreds of organisations and thousands of people to come together again

in 2012 and keep up the pressure!

In April 2012, world leaders will attend the second High-Level Meeting (HLM) of the Sanitation and Water for All partnership in Washington D.C. It is really important that your Development or Finance Minister attends this meeting. You can take the opportunity of your walk to invite them to attend and demand that real progress and firm actions are delivered upon.

What is Sustainable Sanitation?

In light of the earthquakes in Christchurch, floods in Brisbane & elsewhere.....it is apparent that modern centralised sewerage & sewage treatment systems are particularly vulnerable to earthquakes & floods.

I seriously believe we need to re-think the strategy of mixing our poo with our wee & diluting it with vast quantities of 'food-grade' water, then transporting the slurry over vast distances, only to have to separate the poo, wee & water at the other end of the pipe with energy intensive processes.

The following article is reposted from the SuSana website.....

The main objective of a sanitation system is to protect and promote human health by providing a clean environment and breaking the cycle of disease. In order to be sustainable, a sanitation system has to be not only economically viable, socially acceptable, and technically and institutionally appropriate, it should also protect the environment and the natural resources.

When improving an existing and/or designing a new sanitation system, sustainability criteria related to the following aspects should be considered:

1. Health and hygiene: includes the risk of exposure to pathogens and hazardous substances that could affect public health at all points of the sanitation system from the toilet via the collection and treatment system to the point of reuse or disposal and downstream populations. This topic also covers aspects such as hygiene, nutrition and improvement of livelihood achieved by the application of a certain sanitation system, as well as downstream effects.
2. Environment and natural resources: involves the required energy, water and other natural resources for construction, operation and maintenance of the system, as well as the potential emissions to the environment resulting from its use. It also includes the degree of recycling and reuse practiced and the effects of these (e.g. reusing wastewater; returning nutrients and organic material to agriculture), and the protection of other non-renewable resources, e.g. through the production of renewable energies (such as biogas).
3. Technology and operation: incorporates the functionality and the ease with which the entire system including the collection, transport, treatment and reuse and/or final disposal can be constructed, operated and monitored by the local community and/or the technical teams of the local utilities. Furthermore, the robustness of the system, its vulnerability towards power cuts, water shortages, floods, earthquakes etc. and the flexibility and adaptability of its technical elements to the existing infrastructure and to demographic and socio-economic developments are important aspects.
4. Financial and economic issues: relate to the capacity of households and communities to pay for sanitation, including the construction, operation, maintenance and necessary reinvestments in the system. Besides the evaluation of these direct costs also direct benefits e.g. from recycled products (soil conditioner, fertiliser, energy and reclaimed water) and external costs and benefits have to be taken into account. Such external costs are e.g. environmental pollution and health hazards, while benefits include increased agricultural productivity and subsistence economy, employment creation, improved health and reduced environmental risks.
5. Socio-cultural and institutional aspects: the criteria in this category refer to the socio-cultural acceptance and appropriateness of the system, convenience, system perceptions, gender issues and impacts on human dignity, the contribution to food security, compliance with the legal framework and stable and efficient institutional settings.

Most sanitation systems have been designed with these aspects in mind, but in practice they fail far too often because some of the criteria are not met. In fact, there is probably no system which is absolutely sustainable. The concept of sustainability is more of a direction rather than a stage to reach. Nevertheless, it is crucial, that sanitation systems are evaluated carefully with regard to all dimensions of sustainability. Since there is no one-for-all sanitation solution which fulfils the sustainability criteria in different circumstances to the same extent, this system evaluation will depend on the local framework and has to take into consideration existing environmental, technical, socio-cultural and economic conditions. Taking into consideration the entire range of sustainability criteria, it is important to observe some basic principles when planning and implementing a sanitation system. These were already developed some years ago by a group of experts and were endorsed by the members of the Water Supply and Sanitation Collaborative Council as the "Bellagio Principles for Sustainable Sanitation" during its 5th Global Forum in November 2000:

1. Human dignity, quality of life and environmental security at household level should be at the centre of any sanitation approach.
2. In line with good governance principles, decision making should involve participation of all stakeholders, especially the consumers and providers of services.
3. Waste should be considered a resource, and its management should be holistic and form part of integrated water resources, nutrient flow and waste management processes.
4. The domain in which environmental sanitation problems are resolved should be kept to the minimum practicable size (household, neighbourhood, community, town, district, catchment, city).
