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.

Project aims to boost science pass rate

The University of the Free State (UFS), in partnership with computer giant Hewlett Packard (HP), wants to boost the pass rate of its science students by using mobile technology.

The UFS is one of only 15 universities across Europe, the Middle East and Africa and the only university in South Africa to receive a grant from HP to promote mobile technology for teaching in higher education valued at USD$ 100,000 (or about R1 million). Altogether 80 universities from 28 countries applied for the grant.

“Last year HP invited a number of selected universities to submit proposals in which they had to explain how they are going to utilise mobile technologies in the redesign of a course that is presented at the university. The proposal of the Centre for Education Development (CED) at the UFS entitled “Understanding Physics through data logging” was accepted,” says Mr Cobus van Breda, researcher at CED and manager of the project.

According to Mr van Breda, students who do not meet the entrance requirements for the three-year B.Sc. programme have to enroll for the four-year curriculum with the first year actually preparing them for the three-year curriculum.

In order to increase the success rate of these students, the project envisages to enhance their understanding of science principles by utilising the advantages of personal computer (PC) tablet technology and other information and communication technologies (ICT) to support effective teaching and learning methodology.

“By using PC tablet technology in collaboration with data-logging software, a personal response system, the internet and other interactive ICT applications, an environment different from a traditional teaching milieu is created. This will consequently result in a different approach to addressing students’ learning issues,” says Mr van Breda.

The pilot project was launched during the fourth term of 2008 when 130 first-year B.Sc. students (of the four-year curriculum) did the practical component of the physics section of the Concepts in General Science (CGS) module by conducting experiments in a computerised laboratory, using data-logging software amongst other technology applications. “The pilot project delivered good results and students found the interactive application very helpful,” says Mr van Breda.

”The unique feature of the latter is the fact that real-life data can be collected with electronic sensors and instantly presented as computer graphs. It can then be analysed and interpreted immediately, thus more time can be devoted to actual Science principles and phenomena and less time on time-consuming data processing,” says Mr van Breda.

The CGS module can be seen as a prerequisite for further studies in physics at university level and in this regard it is of essence to keep looking for new models of learning and teaching which can result in student success. This year the theoretical and practical component of the physics section of the CGS programme will be done in an integrated manner.
