Turning the tide on SA’s water crisis    

South Africa’s water crisis could be reversed by changing the paradigm of water as a finite resource, and bringing together political will, science, and capital to change the way water is managed.

While South Africa is undeniably experiencing a water crisis, Prof Anthony Turton, a scientist and consultant specialising in water resource management as a strategic issue, says that this situation could be reversed by changing the paradigms around water management.

“In the past, water was seen as single use stock, and the solution to scarcity was to create dams and inter basin transfers,” says Prof Turton.

This approach was the foundation of huge industrial growth around the world, but had unintended consequences. Now, areas of the country that once thrived on a foundation of dammed water face economic ruin.

“The paradigm must change – water is infinitely usable. In a new paradigm of abundance, based on simple scientific truth, we must acknowledge that water is a flux flowing in time and space, therefore it’s an infinitely renewable resource. When it has been used, it returns into the ecosystem, so you haven’t lost it – you still have the same volume,” he says.

In his paper A South African Perspective on Climate Change, Food Security and Water, presented at the 4th BRICS Academic Forum, New Delhi, March 2012, Prof Turton noted that water moves in time and space, driven by the laws of physics, in what is known as the hydrological cycle. “In fact, we have the same volume on our planet today as we had when the dinosaurs roamed free 65 million years ago.”

“The crisis of management is that by seeing water as stock instead of flux, future economic growth has been constricted and cities like Port Elizabeth are on the brink of total collapse. We need R1-trillion to fix what’s broken in the water sector, but the science and technology already exist to make it happen,” he says.

According to Prof Turton desalination and recycling water will substantially improve the situation.

“South Africa has been reclaiming and desalinating acid mine water at Witbank and other areas for at least a decade without problems, proving that we can convert the worst water into the cleanest potable water.

“With an enabling environment and more capital, we can launch more water recycling and desalination programmes,” he says.

“We don’t need to crash and burn – we need credible thought leadership creating a vision supported by robust science, engineering and technology; then we need to populate the vision with enthusiastic and competent people.”

Optimistic that progress is being made (Turning the tide on SA’s water crisis)     

Prof Turton is optimistic that progress is already being made. “There’s a lot of good news. The Minister of Water and Sanitation, Senzo Mchunu, has gone out of his way to reach out to experts and create water war rooms.

“Within the government, we see ‘moderate middle’ components where capital resides, and rational people want to make South Africa a better place. And there are scientists, business chambers and local governments already working on more advanced water recycling and desalination plans.

“The South African Water Chamber, of which I am a founding member, is working with stakeholders and the government to create programmes using special purpose vehicles (SPV’s) as a solution to failing municipalities and to enable economic growth. These SPVs, to be rolled out over the next decade, will mobilise the R1-Trillion we need.”

Research and science important (Turning the tide on SA’s water crisis)    

Prof Turton says research based in science is important in driving progress in sectors such as water resource management.

“During WWII, it became evident that science, engineering, and technology could play a significant role. The invention of radar, directly linked to Prof Basil Schonland at Wits University, was a game changer in the Battle of Britain.

“This triggered the creation of national science councils in all former British colonies, mandated by parliament to generate the science, engineering and technology platform needed to develop the economy.”

Each Commonwealth country has gone different routes, but many still have Council for Scientific and Industrial Research (CSIR) type science councils. In South Africa, the Commission of Enquiry into Water Matters, created the national framework to guide the CSIR in the type of research and technology development needed.

An example is the development of technology to safely recycle sewage as potable water, which was pioneered by the CSIR for implementation in Windhoek, Namibia.

The same happened when the treatment of acid mine water became a crisis in South Africa, with the sulphur removal technology being pioneered by the CSIR.

“We can safely say that the economic development of South Africa has been strongly influenced by science, engineering and technology, with many examples, including the pioneering work into the production of oil from coal,” says Prof Turton.

Research creates a platform (Turning the tide on SA’s water crisis)   

“Research creates an unambiguous platform for the creation of new knowledge around complex issues. Coming from a national science council, that research formed the foundation of policy and thinking in both the public and private spheres.

“Today I still work in two spheres – research exclusively funded by private capital for strictly commercial purposes and research in the public domain for the public good. There is a place for both in society,” says Prof Turton.

Lucia Franco, publishing director of Elsevier’s Water Management journal portfolio, says Prof Turton’s work, and that of others working in the water and sanitation space, is encouraging. “Credible research, with rigorous controls and standards in place, is the foundation for innovative thinking and progress,” says Franco.

In a new series of thought leadership content, Elsevier has engaged some of South Africa’s most noteworthy scientists and academics to explore their latest work to help address the biggest challenges faced by the South African water sector.
