In semi-arid to arid countries water supply challenges will increase in the future with demographic and climate change putting pressure on available resources. Water supply and disposal paradigms of the temperate zone are unsuitable to address these challenges. Innovative water supply and wastewater treatment technologies that are embedded into a holistic integrated water resources management concept are needed, with strong aspects of stakeholder participation, institutional development and capacity building. In central northern Namibia, an eight-year project (CuveWaters) is initiated which links IWRM concept development to the implementation of demand side oriented, appropriate and regionally adapted innovative water technologies.
