Hi Gene, are you a part of the Green Cape? I am part of their ICN (International Cleantech Network) and am looking into going to South Africa, CPT, September or December this year. I presented my work for the Cape Town Water Department in 2010 and asked why they are not implementing rainwater-harvesting on a large scale plan for RDP-housing....I am a building-engineer focus: water-and energy management, educated in Malmö/Sweden & Cape Town/CPUT, and I would love to team up with engineers, leaders, environmental psychologist, innovators, designers and more who believe and wish to be part of the solution of (SubSaharan) Water Crisis. 
It seems that the predicted refugee situation linked to Water Crisis is wider than we can imagine. 
 I have first-hand experience of living without access to clean water, in Gugulethu, and the consequences of such has resulted in that my life project and passion is to combat water crisis.
