Study of the sizing of a fecal sludge treatment station in the town of Kissidougou (Republic of Guinea)

Abstract

The management of fecal sludge is a concern for cities in Guinea such as the city of Kissidougou. This study aims to evaluate the feasibility of setting up a fecal sludge treatment station at the Songbo public landfill, 3 km from the city center of Kissidougou. The methodology adopted for this study is based on: the choice and installation site of the treatment structure, the determination of the geometric parameters of the station, the identification of construction materials and the estimation of the cost of carrying out the the work. For this reason, the upstream hypotheses were defined and the analytical formulas were used. The emptying flow produced by the urban municipality is estimated at 176 m3/day of materials. The volumes of these works are: optional basin (1300 m3); anaerobic pond (384 m3) and maturation pond (1828 m3). The investment cost of building the station amounts to 25 301 546 000 GNF over a requested area of 2 hectares. However, before the establishment of these stations, the Guinean government, through state structures, should carry out preliminary actions to raise awareness among all stakeholders in the sector and regulate it in order to be able to perpetuate this study project.
