The City of Tshwane has made history by being the first municipality in South Africa to use hydropower. This huge project was launched on 29 November 2011. This has realised the objectives of the study that was done by the University of Pretoria through funding from the Water Research Commission, which explored the use of water to generate power that could assist in supplementing the existing supply within a municipality. With this new source of energy, the country could start looking into providing such a service to other areas while reducing the problematic carbon emissions from coal that poses a threat to the environment.
Hydropower is still an untapped resource of energy within the African continent
The ‘Pressure Hydropower System’ has been installed and integrated at the new site, Pierre van Ryneveld reservoir located in the south-eastern part of the City of Tshwane. When operational, the system will generate about 16 Kilowatts of electricity per hour.
The acting Executive Mayor, Councillor Terence Mashego congratulated the team of experts and applauded the excellent work done by the University of Pretoria and its students and the Water Research Commission for funding such an initiative.
“The fact that somebody was employed to take part in the project by working on it or supplying stock for it, the project assisted in putting food on the table for those families’. I also appreciate that the project involved students who should be promoted based on their contribution towards this big initiative’’ says councillor Mashego.

South Africa faces a water crisis that could cripple economic growth and cause a plague of health problems – but critics say the government has yet to act with urgency.
Toxic algae bloom
The most immediate concern is the acid mine drainage (AMD) polluting a vast swathe from the Witwaters-rand to Mpumalanga. Other threats include pesticide run-off, broken infrastructure and failed sewage plants.
As the population grows and economic recovery puts more pressure on limited inland water resources, experts predict a shift of industrial activity to coastal areas where desalination plants will have to meet a growing share of demand.
Environmentalists warn that if the government and industry fail to act, within two years mine water as corrosive as battery acid will gush from Johannesburg’s Wemmer Pan and seep into the city’s streets and gardens.
“It is acutely toxic,” said Mariette Liefferink, who leads a group of non-governmental organisations lobbying for action. “It affects the soil and neural development of the foetus, which leads to mental retardation; it will cause cancer, cognitive problems, skin lesions,” she said. “These are all the foreseeable risks if we do not manage our AMD.”
Acid mine drainage, which occurs when mines close and stop pumping water out of shafts, has contaminated streams and dams on the West and East Rand that feed into the Limpopo and Vaal rivers. Treatment by utilities such as Rand Water renders the water safe, but those who drink straight from rivers are at risk. Continue reading Water crisis could cripple economic growth

South Africa should start looking for alternative solutions to control malaria-carrying mosquitoes. Using DDT to curb the spread of malaria has been proven by researchers to pose a huge risk to human beings. According to [...]
