Citadel's chief investment strategist Dave Mohr recently forecast that South Africa was entering a recession, much to Trevor Manuel's annoyance. He was not as pessimistic. Manuel believes that 2010's FIFA Soccer World Cup infrastructure development, coupled with his 2009 budget allocation of R787 billion over three years for yet more infrastructure development, would protect South Africa, to a large extent, from the negative effects of the global economic downturn.

The recently released results of the biannual Consulting Engineers South Africa (CESA) Management Information Survey (MIS) for the period July to December 2008, indicate that the industry continues to grow although it is starting to show a slight levelling off, with companies becoming more cautious. It is 'business as usual' for most consulting engineering companies, apart from those operating in the mining as well as the commercial and industrial property sectors where the current economic climate has had a definite negative impact. Good news is that international work within Africa is on the increase.

Everyone is talking about climate change. Scientific studies confirm an increase in concentration of greenhouse gases (GHG). The largest growth of GHG emissions between 1970 and 2004 has come from energy supply, transport and industry, while residential and commercial buildings, forestry and deforestation and agricultural sectors have been growing at a lower rate. South Africa is among the top 20 international per capita emitters of GHG, making up 1.6% of the global total. South Africa is vulnerable to the impact of climate change and, as a signatory to both the UNFCCC and Kyoto Protocol, has begun implementing mitigation measures to reduce GHG emissions.

The fight between advocates of water-carriage technology and supporters of dry conservancy technologies was an uneven one from the start. The government and the engineers who advised them generally favoured water-carriage systems because they could be controlled more easily and necessitated a centralised government bureaucracy staffed by experts. Sewers were automatic and took responsibility away from individual householders, landlords and private carters who it was felt could not be trusted.

The George Municipality initiated a water resource study in 2005, with the main purpose being to augment the water supply to George in terms of the municipality's strategic planning for the next 20 years. In 2006, the City of George faced an extreme drought, with the Garden Route Dam at 42% and no end in sight to the drought. This drought further emphasised the urgent need for augmentation. The rapid growth of development in the region added further pressure to solve the situation for the short term until more extensive bulk water augmentation schemes could be put in place.
