Water and wastewater treatment are key to protect humans in cities by providing safe water and urban hygiene and to protect the aquatic environment from pollutants. Over the past century, urban water management allowed for healthy and pleasant living conditions in ever-growing cities in many parts of the world. This presentation will discuss the potential for local reuse of treated greywater and drivers for implementation. What are the scientific and technological challenges? How can appropriate local water reuse be implemented in a way that it does not jeopardize today’s achievements in urban water management and urban hygiene? Basic sciences for gravity driven membrane (GDM) filtration and technology development for reuse of hand washing water in informal settlements or resource recovery at the building scale will be discussed.
