Inadequate water and sanitation infrastructure continue to impede sustainable development and inclusive growth across the world, with some countries suffering a 7% GDP loss per annum as a result.


About 2.1 billion people lack access to safely-managed drinking water services, while 4.5 billion lack access to basic sanitation. More calamitous, poor water and sanitation services claim 675 000 lives globally each year.


TCTA Senior Manager: Evaluation & Knowledge, Xolani Ngonini, shared some of these statistics during an internal knowledge -sharing session held on 27 August. “Water will play a key role in achieving the Sustainable Development Goals (SDGs) by 2030, making water-related investments a necessary foundation for sustainable development and inclusive growth,” Mr Ngonini emphasised. (Read more)
