Opinion article by Prof Anthony Turton, Centre for Environmental Management, University of the Free State. 


South Africa and Australia, both arid countries with historical ties to the British Empire, face significant water management challenges. Despite common legal and parliamentary systems, the two nations diverge in their approaches to water sector governance, leading to markedly different outcomes in economic prosperity.

In examining the disparities, it becomes evident that contemporary South Africa is grappling with a scenario resembling a failed state, particularly evident in the breakdown of the electricity and water services sector. This raises a fundamental question – why is the South African water sector faltering while its Australian counterpart thrives? 

Why is the South African water sector collapsing?

Addressing the collapse of the South African water sector requires a nuanced understanding rooted in historical context. The origins of the issue can be traced back to the British Empire’s consideration of federalism during the Anglo-Zulu War. While federalism found success in Canada and Australia, it failed to take root in South Africa.

Fast forward to the present, South Africa operates as a unitary state with a centralised water policy and national water law. This uniform approach leaves little room for local variation, resulting in a cookie-cutter model applied nationwide. Despite water being a constitutional right and given that free basic water is guaranteed to all, the sector faces challenges such as high levels of unaccounted-for water, leakages, and poor management. The absence of justiciable water rights and the separation of water from land ownership hinder private sector involvement. Consequently, utilities are reliant on government bailouts, a situation exacerbated by failing water and electricity grids, diminishing the tax base, and escalating unemployment. 

Australia’s flourishing water sector: A model of innovation 

Australia’s federal structure facilitates a diverse array of state policies and laws, promoting adaptability to local conditions. Boasting over 30 distinct water authorities, each tailored to meet local needs, Australia thrives on a justiciable water right system that allows private ownership. Market forces drive water to its most productive use, and investor confidence is a cornerstone in decision-making. 

Australia’s innovative and market-oriented approach has resulted in well-managed utilities with robust balance sheets. The ability to raise capital from the bond market reduces reliance on public funds for bailouts. Groundwater plays a vital role, accounting for around 40% of the total resource, while innovative technologies, such as seawater desalination, are embraced at the utility scale.   

South Africa’s water sector: uninvestable and facing challenges 

Contrastingly, South Africa’s water sector faces challenges. A lack of innovative approaches, coupled with a rigid, cookie-cutter methodology has stifled local imagination. The state’s hostility towards private capital has rendered the water sector generally uninvestable. While some large water boards still maintain strong balance sheets, the growing debt burden from non-payment by municipalities poses a threat. Limited development of groundwater at utility scale, coupled with a reluctance to replicate successful initiatives, further compounds the challenges. Sea water desalination, where it exists, is confined to small package plants in distressed municipalities along the coast, often seen as unsustainable. 

Australia’s innovative solutions: integrating technology and conservation

Australia stands out for its innovative solutions. With a vibrant private sector driving constant technological advancements, groundwater is a key element in most utilities, actively integrated into the grid and accounting for around 40% of the total resource. Building codes align with water conservation, ensuring rainwater harvesting and aquifer recharge are actively pursued at various levels, including suburb and city. The management of sewage, increasingly sophisticated water recovery from waste, and seawater desalination at utility scale funded by private capital showcase Australia’s forward-thinking approach.  

Centralisation versus decentralisation  

In conclusion, the weakness of South Africa’s water sector lies in the highly centralised approach, resulting in ineffective, one-size-fits-all solutions. Local authorities often lack imagination, relying heavily on taxpayers and hindering innovation. Suspicion towards capital and technology further limits the sectors development. In contrast, Australia’s decentralised approach fosters vibrant water utilities capable of attracting both capital and technology. Entrepreneurs’ initiatives in desalination and water recovery programmes inspire investor confidence, leading to capital influx and secure, water-efficient local economies.

Imagine that you have been diagnosed with bone cancer and only have six months to live. You are in a wheelchair because the pain in your legs is so immense that you can’t walk anymore – similar to a mechanism eating your bones from the inside.

You are lucky though, since you could be injected with a drug to control the pain so effective that you will be able to get out of the wheelchair within a day-and-a-half and be able to walk again. Real-life incidents like these provide intense job satisfaction to Prof André Roodt, Head of Inorganic Chemistry at the University of the Free State (UFS). The research, which is conducted by the Inorganic Group at the UFS, contributes greatly to the availability of pain therapy that does not involve drugs, but improves the quality of life for cancer patients.

The research conducted by the Inorganic Group under the leadership of Prof Roodt, plays a major role in the clever design of model medicines to better detect and treat cancer.

The Department of Chemistry is one of approximately 10 institutions worldwide that conducts research on chemical mechanisms to identify and control cancer. “The fact that we are able to cooperate with the Departments of Nuclear Medicine and Medical Physics at the UFS, the Animal Research Centre, and other collaborators in South Africa and abroad, but especially the methodology we utilise to conduct research (studying the chemical manner in which drugs are absorbed in cancer as well as the time involved), enhances the possibility of making a contribution to cancer research,” says Prof Roodt.

Technique to detect cancer spots on bone
According to the professor, there are various ways of detecting cancer in the body. Cancer can, inter alia, be identified by analysing blood, X-rays (external) or through an internal technique where the patient is injected with a radioactive isotope.

Prof Roodt explains: “The doctor suspects that the patient has bone cancer and injects the person with a drug consisting of an isotope (only emits X-rays and does no damage to tissue) that is connected to a phosphonate (similar to those used for osteoporosis). Once the drug is injected, the isotope (Technetium-99m) moves to the spot on the bone where the cancer is located. The gamma rays in the isotope illuminate the area and the doctor can see exactly where treatment should be applied. The Technetium-99m has the same intensity gamma rays as normal X-rays and therefore operates the same as an internal X-ray supply.” With this technique, the doctor can see where the cancer spots are within a few hours.

The same technique can be used to identify inactive parts of the brain in Alzheimer patients, as well as areas of the heart where there is no blood supply or where the heart muscle is dead.

Therapeutic irradiation of cancer
For the treatment of pain connected with cancer, the isotope Rhenium-186 is injected. Similar to the manner in which the Technetium-99m phosphonate compound is ingested into the body, the Rhenium-186 phosphonate travels to the cancer spots. Patients thus receive therapeutic irradiation – a technique known as palliative therapy, which is excellent for treating pain. A dosage of this therapy usually lasts for about two months.

The therapy is, however, patient specific. The dosages should correspond with the occurrence and size of cancer spots in the patient’s body. First, the location of the cancer will be determined by means of a technetium scan. After that, the size of the area where the cancer occurs has to be determined. The dosage for addressing total pain distribution will be calculated according to these results.

Technique to detect cancer spots on soft tissue
Another technique to detect cancer as spots on bone or in soft tissue and organs throughout the body is by utilising a different type of irradiation, a so-called PET isotope. The Fluor-18 isotope is currently used widely, and in Pretoria a machine called a cyclotron was produced by Dr Gerdus Kemp, who is a former PhD graduate from the Inorganic Research Group. The F-18 is then hidden within a glucose molecule and a patient will be injected with the drug after being tranquillised and after the metabolism has been lowered considerably. The glucose, which is the ‘food' that cancer needs to grow, will then travel directly to the cancer area and the specific area where the cancer is located will thus be traced and ‘illuminated’ by the Fluor-18, which emits its own 'X-rays'.

In the late 80s, Prof Roodt did his own postdoctoral study on this research in the US. He started collaborating with the Department of Nuclear Medicine at the UFS in the early 90s, when he initiated testing for this research.

Through their research of more than 15 years, the Inorganic Group in the Department of Chemistry has made a major contribution to cancer research. Research on mechanisms for the detection of cancer, by designing new clever chemical agents, and the chemical ways in which these agents are taken up in the body, especially contributes to the development in terms of cancer therapy and imaging, and has been used by a number of hospitals in South Africa.

The future holds great promise
Prof Roodt and his team are already working on a bilateral study between the UFS and Kenya. It involves the linking of radio isotopes, as mentioned above, to known natural products (such as rooibos tea), which possess anti-cancer qualities.
