WATER RESEARCH & INNOVATION (GLOBAL AND NATIONAL TRENDS) Valerie Naidoo Water Research Commission Cape Town Accelerate, 2017
Importance of investment in water and need to improve access and quality of water - for economic growth Economy GLOBAL TRENDS Water 780-million people did not have access to improved sources of drinking water Sanitation 2.5-billion were without improved sanitation ; Sub- Saharan Africa - lowest sanitation coverage of 70% there will be no SADC industrial revolution without substantially higher investment in infrastructure, upgrading and diversifying the capital stock and the provision of the high technology skills necessary in the modern industry

WATER RECLAMATION Various Examples Of This Being Done In SA With Variations Around Blending, Recharge, And Use. Social Perceptions And Acceptance Are Critical But Trust In Institutions To Deliver 100% Assurance Of Quality Is Vital. Hence, Wastewater Treatment Plants Need To Be Managed Well And To Standard. Plant Wide Model Developed At Uct Can Assist Optimized Process Control Tested By Trusense Will Improve Final Quality Energy Efficiency Using The Combination Can Be Reduced By 20 To 40% (Plant Age)
