FSM in Léo City (Burkina Faso)

The management of faecal sludge is a concern for the cities of Burkina Faso, in particular for those which are in the implementation of their strategic sanitation plan. This is the framework for this study, which aims to contribute to the control of data on sludge flows and to provide a basis for development activities in the city of Léo. The work consisted in making an inventory of the excreta disposal structures through household surveys and field observations. It emerged that 96% of households have latrines, with an equipping rate of 59% with traditional structures and 38% with approved ones. Public places have high rates of equipment with approved structures, despite the insufficient number of cabins for the hygienic management of periods and for people with reduced mobility. The surveys also revealed that 11% of households had recourse to emptying, which is most often done manually (88%), with the field as the usual place of unloading (87%). The evaluation of sludge flows made by the SFD tool showed that 66% of the city’s sludge is poorly managed, and the management capacity evaluation was made thanks to the identification and characterization of actors, and SWOT analysis. Analysis of the previous data made it possible to propose improvements through the system-wide approach, highlighting some functional determinants. This is how a logical framework and a synoptic diagram were drawn up, and the gap to be filled at the level of the access link was defined in households and public places. Actions were also proposed for the intermediate link, and a STBV was designed for the treatment link with the construction in 5 phases of 131 sludge drying beds, lagoon basins and a sanitation area over a total area of 20,362 m2.
