People working at a garbage field in Bamako, Mali. According to Protos, a Belgian charity that promotes access to safe water, more than 85 percent of Bamako households handle their own sanitation — meaning they have to dispose of any wastewater and excrement themselves. Bamako lacks a proper sewage system. Most wastewater is evacuated into the Niger River, which runs through the city.
