Our Relentless Water Dilemma
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.”

Little ‘Devil’s Worm’ on Top 10 New Species list

A minuscule little worm found and researched with the assistance of researchers at the university has made it onto the list of Top 10 New Species of the world. The list was published by the International Institute for Species Exploration (IISE) at Arizona State University and a committee of scientists from around the world. It lists the top ten new species described in 2011.

An article on the new worm species appeared in the authoritative journal Nature in June 2011.
 
Prof. Esta van Heerden, leader of the university’s research team, says, “In our wildest dreams, we could not have imagined that we would get so much reaction from the worm’s discovery. We had to do so many checks and balances to convince Nature that the worm could survive in the old and warm water. We were very excited when the article was accepted but the media reaction was unbelievable.”
 
The tiny nematode, Halicephalobus mephisto (Devil’s Worm) of about 0,5 mm in length, is the deepest-living terrestrial multi-cellular organism on earth. It was discovered in the Beatrix gold mine near Welkom at a depth of 1,3 km.
 
The IISE says in a statement the species is remarkable for surviving immense underground pressure as well as high temperatures. The borehole water where this species lives has not been in contact with the earth’s atmosphere for the last 4 000 to 6 000 years.  
 
This top-10 list includes a sneezing monkey; a beautiful, but venomous jellyfish; a fungus named after a popular TV cartoon character; a night-blooming orchid; an ancient walking cactus creature; and a tiny wasp. A vibrant poppy, a giant millipede and a blue tarantula also made it onto the list.
 
The international selection committee made its choice from more than 200 nominations. They looked for species that captured the attention because they were unusual or because they had bizarre traits. Some of the new species have interesting names.
 
Prof. Van Heerden says, “We are very thankful for the exposure that the university gets as a result of the inclusion on the list and we enjoy the international cooperation immensely.”
