The former Kovsie Neil Powell, Blitzboks coach, steered the South African sevens rugby side to another Commonwealth Games gold medal in Birmingham, England.

Hard work does not necessarily guarantee success, but it is part of success.

According to Neil Powell, the Blitzboks head coach, this is what his players showed by turning the team’s recent misfortunes into Commonwealth Games gold.

The South African sevens side rewarded the University of the Free State (UFS) alumnus – who will be parting ways with the team next month – by claiming another Games top spot.

The decorated coach steered his troops to a gold medal in Birmingham, England, after defeating Fiji by an impressive 31-7 in the final late on Sunday evening.

Powell and the Blitzboks also won Commonwealth gold in Glasgow, Scotland, in 2014.

After nine successful years with the Blitzboks, the former Kovsie will become the new Director of Rugby at the Sharks in September 2022. His last sevens tournament will be the World Cup from 9 to 11 September 2022 in Cape Town.

Reset and rewarded

The Blitzboks, however, did not go into the Commonwealth Games as favourites, as they struggled in the last four HSBC World Rugby Sevens Series tournaments.

After winning the first four tournaments of the season, they failed to reach the semi-finals in Singapore, Vancouver, Toulouse, and London.

“After the World Series tournament in London, we had to reset and re-evaluate our goals for the rest of the season and the last three tournaments, the Commonwealth Games, the Los Angeles Sevens, and finally the Rugby World Cup Sevens,” Powell said in a SA Rugby media release.

“The guys really worked hard in the build-up to this tournament, and I’m glad they got rewarded for it.”

Memories from Glasgow Games

In 2016, Powell received a Cum Laude Award at the UFS Chancellor’s Distinguished Alumni Awards when the Blitzboks won Olympic bronze in Rio de Janeiro.

Powell represented the Cheetahs, Sharks, Griquas, Blue Bulls, and Blitzboks in his playing days and is one of 28 national sevens players produced by the UFS.

“It’s amazing to have won the gold medal again, like we did eight years ago in Glasgow, and especially after we finished fourth and didn’t win a medal at the previous Commonwealth Games in Australia, so there is a lot of emotion and the victory brought back memories of what happened in Glasgow in 2014.”

He said it was important for the team’s confidence to deliver in Birmingham in order to get momentum and belief back.

Powell hopes his side can take this into the last World Series tournament in Los Angeles on 27 and 28 August 2022, and the World Cup.

South Africa are on top of the World Series log and can take the overall honours with a good LA performance.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
