In Dar es Salaam, Tanzania’s biggest city, most people depend on pit latrines. They leak and flood, are only infrequently emptied, and for users and sewage collectors alike they’re a source of potentially fatal diseases like cholera and typhoid. Water Aid is pioneering a cheap and simple pump and motorbike device that empties up to six latrines a day. And it’s a cleaner and cheaper option than traditional methods.
In Dar es Salaam, only 10% of the city is connected to mains sewage. wateraid.org/uk
