Field surveys conducted in 2010 in the peri-urban neighborhoods of Bangui, particularly Cattin - Plateau and Kokoro - Boeing, revealed that more than 80% of the people represented in the two neighborhoods do not have access to drinking water through the network of the Central African Water Distribution Company, SODECA for short. This situation is worrying in these peri-urban neighborhoods, which are dominated by informal settlements. Indeed, these neighborhoods should benefit from the SODECA water supply network instead of hydraulic solutions, but unfortunately they are poorly served with drinking water. They are traditionally implemented, despite their unsuitability and the very poor quality of the water that is associated. This situation exposes these populations to pathogenic risks, particularly diarrhea, especially among children under five years of age.
