Like the majority sub-Saharan Africa cities, Aneho city in Togo is experiencing the problem of sustainable management of fecal sludge. The objective of this study is to contribute to better management of fecal sludge from Aneho city. To achieve this, an inventory of the management of fecal sludge in the city was carried out, followed by the quantification and characterization of the sludge produced according to the different types of existing sanitation systems. The results showed that the fecal sludge sector is experiencing shortcomings in its management. The sludge mainly discharged by mechanical means (62%) is transported to an official unmanaged disposal site or to farmers' fields without treatment. The amount of mud produced per year in the city is between 3,534 and 7,442 m3. The physico-chemical characterization results reveal that the sludge from dry pits was more loaded with pollutants than that from wet pits. The sludge with a neutral characteristic and a high salinity is rich in ammonium, phosphorus, nitrates with a COD/BOD5 ratio equal to 2.1. Heavy metals including Iron, Copper, Zinc, and Manganese have a relatively apparent concentration in the sludge. The microbiological characterization showed the significant presence of fecal and pathogenic germs in the sludge. From this study, knowing of the sludge quantity and characteristics produced at Aneho, will allow choosing an appropriate treatment based on other local criteria.
