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


This week, our national sewage crisis really began to bite. A media storm has erupted over the cholera outbreak in Hammanskraal, while some families are now grieving for their dead relatives. It is important that we start this story by remembering the dead, because they were breadwinners in families, all doing their best to survive the tribulations of our times. They died unnecessarily, the victims of the slow onset disaster I spoke of in 2008 at a conference titled ‘Science Real and Relevant’.

At that conference, reference was made to three water quality challenges that we, in the dwindling aquatic sciences community, were all too aware of, but unable to speak about. We noted trends that data sets were showing us, and we felt a growing sense of alarm about the consequences of the trajectories on the graphs. We noted that our systems were failing rapidly, with much of our hard infrastructure in the water sector approaching the end of its useful design life. We noted with alarm the loss of skills, as the ravages of purging took its toll on our science, engineering, and technology core.  We noted the loss of dilution capacity in all our rivers after the first National Water Resource Strategy (NWRS), mandated by the National Water Act (NWA), indicated that we had allocated 98% of all the water in all our rivers and dams, as far back as 2002. We noted the migration of plumes of uranium moving into the headwaters of both the Vaal and Crocodile Rivers, both tributaries of the Orange and Limpopo respectively, driven by uncontrolled decant of acid mine water, as the gold mining industry started to collapse.

From these sets of data, a simple conclusion was drawn – SA was heading for a slow onset disaster unless we could convince our political leadership that we need to do things differently.

Here are some facts in the wake of the cholera crisis.

Fact 1 – The South African economy ran out of water in 2002 when the NWRS revealed that we had already allocated 98% of all the water we have legally available in terms of the NWA. This means that we cannot convince investors to have confidence in our future. We face an investment drought as a direct result of this startling but irrefutable fact.

Fact 2 – We produce more than 5 billion litres of sewage daily, all of which is discharged into our rivers and dams, only about 10% of which is treated to a standard that makes it safe for direct human contact.

Fact 3 – The Green and Blue Drop Reporting System was suspended by Nomvula Mokonyane when the data was showing trends in the failure of our sewage treatment works. This is like a pilot in a commercial airliner switching off the radar screen because the information being revealed was becoming uncomfortable to the poorly trained, but rapidly promoted cockpit crew. This is the undeniable genesis of the deaths we are seeing today.

Fact 4 – Because of Facts 1 and 2 combined, our tsunami of sewage can no longer be diluted in our rivers. In fact, more than 60% of all our large dams are now eutrophic, with highly enriched water breeding toxic cyanobacteria, all thriving off the warming water and growing flow of nutrients from sewage. In simple truth, we have lost our dilution capacity, and our rivers have been turned into hazardous sewers breeding harmful pathogens, including the flesh-eating bacteria that cost RW Johnson his leg. This means that cholera is only one of the risks we are facing from raw sewage in our rivers. For example, Hepatitis A is a waterborne pathogen directly related to sewage-contaminated rivers, but this is being reported separately in our slow onset disaster, so the penny has yet to drop.

Fact 5 – The current Minister of Water and Sanitation, Mr Senzo Mchunu, was brave enough to reinstate the Green and Blue Drop Reporting System, which has now shown that more than 90% of our wastewater treatment works are dysfunctional. He is a brave man in so doing, and I want to publicly support him as he tries to rebuild the trust that was destroyed by a previous minister.

So, this is where we are today. People are dying as a direct consequence of decisions made by a former minister, who clearly failed in her custodial role. She must ultimately be held to account for her dereliction of duty and blatant betrayal of public trust. Just this week, a spokesperson for the Presidency noted that his office was unable to intervene in another crisis, because the cooperative governance clause in our constitution prevented one sphere of government from intervening in the activities of another sphere. We must challenge this constitutional weakness and seek clarification from the appropriate court. How can a constitutional clause be so irrational as to prevent one part of government from intervening in another to avert a catastrophe? How many more lives must be lost to the absurdity of legal protection for those in power, while their activities are clearly not in the best interest of society as a whole? Surely a constitutional democracy is about empowering the citizens by protecting them against the consequences of failed service delivery.

From the depths of despair in the families of those whose lives have been lost to an entirely preventable illness, let us find the strength to rally as one and shout out, ‘enough is enough’. Our noble constitution grants all citizens rights to a better life in an environment that is safe from harm. Let us restore that dream by demanding that our sewage flows be brought under control. Surely this is the basis of modern civilization, irrespective of political persuasion or ideological preference.

UFS student makes breakthrough in the application of nanorobots
2005-04-21

A student from the University of the Free State (UFS) has made a ground-breaking discovery in the field of microbiology by uncovering a series of new compounds that may in future be used to lubricate man-made nanorobots.

Mr Olihile Sebolai, a full-time student at the UFS’s Department of Microbial- Biochemical and Food Biotechnology, made this discovery while working on his M Sc-study on yeast.

With this discovery Mr Sebolai will also be awarded six prestigious prizes during this week’s autumn graduation ceremony at the UFS.  This university has recognised this exceptional achievement as a build-up to the celebration of national Science and Technology week next month.     

Mr Sebolai’s dissertation on the yeast genus Saccharomycopsis Schionning has been published in an accredited international journal of repute. 

“Words cannot describe how excited I am. I never expected to receive such recognition for my studies.  I am humbled by all of this,” said Mr Sebolai.

The Lipid Biotechnology Group at the UFS recently discovered that some yeasts produce their own water-propelled capsules in which they are transported.  These capsules have different shapes and resemble among others miniature flying saucers, hats with razor sharp brims etc.  “In order to function properly, parts of the capsules are oiled with prehistoric lubricants – lubricants that are produced by yeasts and that probably existed for many millions of years as yeasts developed,” said Mr Sebolai.  

According to Mr Sebolai these capsules are so small that approximately 300 can be fitted into the full-stop at the end of a sentence and are therefore invisible to the naked eye.

“With my studies I discovered many new compounds that resemble these prehistoric lubricants.  These lubricants may in future be used to lubricate man-made nanorobots and are similar in size compared to yeast capsules,” said Mr Sebolai.  The nanorobots are used to perform tasks in places that are invisible to the naked eye and could one day be used, among others, to clean up human arteries.

Mr Sebolai has been interested in the subject of Micro technology since he was at RT Mokgopa High School in Thaba ‘Nchu.  “I was specifically interested in the many possible applications the subject has – in the industry, as well as in medicine,” said Mr Sebolai. 

His next goal is to successfully complete his Ph D-degree.

The prizes that will be awarded to Mr Sebolai this week include:

Best Magister student at the UFS (Senate medal and prize);

Best Magister student in the Faculty of Natural and Agricultural Science and Dean’s medal at the same faculty;

The Andries Brink – Sasol-prize for the best M Sc dissertation in Microbiology;

The JP van der Walt prize for best M Sc dissertation in yeast science;

The Chris Small prize for an outstanding Master’s dissertation; and

Honorary colours awarded by the UFS Student Representative Council
