Dr Tseliso Ntili, HOD of the Free State Department of Water and Sanitation, warns that pollution caused by mismanagement of municipal water-treatment works puts severe pressure on the province’s water security.
“Despite our water challenges, Bloemfontein will never become a second Cape Town.” This firm assurance was given by Dr Tseliso Ntili, HOD of the Free State Department of Water and Sanitation, during his presentation at the recent regional seminar of the Faculty of Law’s Environmental Law Association.
The theme of the seminar was Water Quality and Water Security in Bloemfontein and was attended by staff and students from the Faculty of Law and the Faculty of Natural and Agricultural Sciences, as well as relevant role players from private, business, and government sectors.
Not enough water for city’s needs
Water restrictions in some form do seem to remain part of our future landscape though, as Dr Ntsili explained that the city’s current water yield of 218 megalitres per day still fell short of the demand of 259 megalitres per day.
Pollution and mismanagement at municipal level
He pointed out that a big cause for concern was that 75% of the Free State’s waste-water treatment works were dysfunctional. Housekeeping and security at these plants are often severely neglected. Yet, it is difficult for the Department of Water and Sanitation to act against offending municipalities.
“In intra-governmental disputes, the courts must be satisfied that organs of state have taken all reasonable steps to settle contentions – which can be a time-consuming process,” he explained.
Dr Ntsili said that the Caledon River System’s dwindling water levels due to low rainfall and siltation was also a concern, but that plans were underway to supplement the water supply to Bloemfontein via the Gariep Dam by 2026.
However, he warned that poor water management could drastically affect these long-term plans.
“If we can’t manage pollution, the cost will be high. Water security will be challenged, and we will have water shortages – not because of drought, but because of negligence.”
Childhood obesity should be curbed early

Serious intervention by parents is required to deal
with childhood obesity. Prof Louise van den Berg and
a group of final-year PhD students worked on a study
about the prevalence of obesity in six-year-olds in
South Africa.

If your child is overweight when they start school at the age of six, unless you do something about it at that point, the indications are they are going to be overweight teenagers and obese adults. This is according to University of the Free State’s Prof Louise van den Berg.
Evidence has shown that overweight children and teenagers have a greater risk of developing lifestyle diseases such as type 2 diabetes, hypertension and cardiovascular disease later in life, and dying prematurely.
Obesity is a global pandemic rapidly spreading among adults and children, in developed and developing countries alike.
Dr Van den Berg worked with Keagan Di Ascenzo, Maryke Ferreira, Monja-Marie Kok, Anneke Lauwrens, all PhD students with the Department of Nutrition and Dietetics, to conduct the study. Their research found that children who are overweight by the time they turn six should be screened for weight problems.
Why six-year-olds?
Children who are overweight between the ages of two and five are five times more likely to be overweight when they are 12. There are two periods in a normal life cycle when the body makes new fat cells. The first is in the uterus and the second is around the age of six. The second phase lasts from the age of six to puberty.
The study assessed the prevalence of obesity in six-year-olds as part of a campaign in South Africa to raise awareness of the problem among parents and educators.
A total of 99 children were chosen from seven schools in Mangaung, the capital city of Free State. The schools were chosen from quintile four and five schools, which when measured by their own resources and economic circumstances, are well resourced and serve largely middle-class and wealthy communities.
The children’s weight, height and waist circumference were measured and used to calculate a body mass index score and waist-to-height ratio. Both these figures are good predictors for future lifestyle disease risks such as type 2 diabetes, hypertension and cardiovascular disease. A person with a good waist-to-height ratio can wrap a piece of string equal to their height around their waist at least twice.
When the children had a higher body mass index, they also had an increased waist to height ratio. The study found one in four children from the schools surveyed were overweight when they started primary school.
Nipping the fat in the bud
Although there are many factors that play a role in preventing childhood obesity, parents’ perceptions of their children’s weight play an important role. A recent study found that more than 50% of parents underestimate the weight of their obese children. These parents remain unaware of the risks their children face and are not motivated to take any action.
At least half of the parents whose children are overweight struggle to recognise their children’s weight problems fearing that they will be labelled or stigmatised. By the time they turn six overweight children should be referred to dieticians and nutritionists who are qualified to guide their parents in getting them to eat well and be more physically active at pre-primary and primary school.
The high prevalence of weight problems among six-year-olds found in this study is an urgent call to healthcare professionals to step up and empower parents, educators and children with the necessary skills for healthy dietary practices and adequate physical activity.
