water infrastructure issues

Could we have a new Eskom called WaterKom?

According to Financial Mail, SA could set up an Eskom style firm to manage water resources in South Africa. For a second time in 10 years, government will attempt to set up an Eskom-style agency to manage SA’s large water infrastructure investments. It will own, finance, operate and maintain critical national water infrastructure such as dams and pipelines. The intention, which is laid out in the water affairs department’s recently released second national water resource strategy (NWRS), is yet to be formally announced by water affairs minister Edna Molewa. But […]

South Africa: not a drop to drink

South Africa and the dripping time bomb

Reasons why Gauteng is out of water. Gauteng like any other city is forlornly short of finance to upgrade existing and build new sewerage treatment works.  The resultant sewerage flowing into rivers arrives in rivers to dams like Hartebeespoort Dam, and increasingly back into the Vaal.  There this concoction of high BOD (biological Oxygen Demand) water, industrial waste containing heavy metals and acid mine drainage (AMD) is fast making the Vaal water useless.  For instance, the Vaal Barrage which is the old Vaal Dam is useless water.  Rand Water used […]

Learn To Be Self Sufficient

ESKOM is the undisputed, largest single user of water in South Africa. Medupi, the largest coal fired power station in the world yet to come on stream will be cooled by dry coolers, that come at a huge cost.  15% of the energy generated will be lost to cooling.  If the power is to be delivered to Cape Town some 2000 kilometres from Medupi, then this will be the furthest power line delivery in the world.  The loss in the transport of this power will be a further 25%.  The […]

Why Don’t we Love Water anymore?

M&G SIPHO KINGS-MCDERMOTT It’s easy to forget the importance of water. Most people reading this live in a city — all you have to do is turn a tap. And the quality is almost the best in the world. It’s almost too good. Actually, it is too good and it’s too cheap. We’ve forgotten where water comes from, how valuable it is, and how vulnerable we are because of it. A while ago my dad told me water will be the biggest news story of the 21st century. Many of […]

Power Competition between Cars and Water. Chapter 1

We have new competition for supply from electrical generation. This edition of water versus cars et al is over five chapters. We look at the carbon dioxide emission of producing electrical energy for the purposes of domestic use, energy hungry desalination of sea water and electrical car scooter and bicycle use. We look at giveaway pointers at how much energy is expected to be used by which sector, and at hard facts about demand versus supply of water and energy. Let us begin: Medupi is not on track. There is […]

Could SA run out of water by 2020?

South Africans must brace themselves for steep water tariff increases in the coming months, water experts have warned. Though the exact increases are yet to be calculated, the impending increases would be similar to the astronomical electricity tariff hikes that hit South Africa early last year. The proposed increases follow last month’s warning that South Africa will run out of water by 2020 if nothing is done to supplement water resources. Speaking on the eve of World Water Week (March 20-26), Water Affairs acting director-general Trevor Balzer said South Africa’s […]
