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.”
UFS entomologists describe a new spider species

It is about 3mm in size and almost looks like a ladybird, but this new spider is the cause of great excitement at the University of the Free State’s (UFS’s) Department of Zoology and Entomology.
The new species of spider, now known as Rhene amanzi, was recently described for the first time and was ‘introduced’ to other arachnologist at the recent congress of the African Arachnology Society at Amanzi Private Reserve.
Dr Charles Haddad, senior lecturer in the UFS’s Department of Zoology and Entomology, said they already stumbled upon the male spider in 2010 when a student was doing research at the reserve. After a very long process, the spider was described and a couple of weeks ago, whilst at the congress, they also found the female.
“Up to now we only know that the spider lives in trees in the Brandfort area. The range could be wider, but since it was only described recently, other arachnologists will only now be able to identify accurately.”
Dr Haddad says they still have to determine how many eggs the female is able to lay, what the spider’s life cycle looks like and what their habitual preferences are.
“What we do know is that it probably isn’t poisonous and that the spider imitates a ladybird in order to protect itself against predators.”
