Many households in some of South Africa’s biggest cities have been facing water restrictions in recent times – sometimes lasting for days at a time. People have had to make tough choices. For example, if you have a bottle of water in your house, are you going to drink it or use it for flushing the toilet? Sanitation scientist Dr Preyan Arumugam-Nanoolal argues that, even without water restrictions, it simply doesn’t make sense to keep flushing drinkable water down the toilet. She and her colleagues have been evaluating alternative sanitation technologies. Ina Skosana had a conversation with her about this research and innovations surrounding it.
