In Cameroon, given the socio-economic and health impact of diseases (cholera, typhoid, amoebiasis, etc.) linked to poor access to drinking water (population access rate to drinking water: 23% in urban areas and 10% in rural areas1 ) and poor compliance with hygiene and sanitation (sustainable access to improved sanitation for rural and urban populations: 42% versus 58%)2 , it is important to note that this is not a new phenomenon: 23% in urban areas and 10% in rural areas1) and the low compliance with hygiene and sanitation (sustainable access of rural and urban populations to improved sanitation: 42% vs. 58%)2 , IRESCO conducts interventions aimed at raising the said indicators related to human development related to water and sanitation. Its actions are structured around water and sanitation services installation projects including improved wells and springs, drainage, cleaning, pesticide campaigns, etc. These interventions are carried out in a participatory implementation and continuity approach for ownership and sustainability characterized by the promotion of the necessary capacities in the target communities.
