Assainissement par toilettes sèches à litière biomaîtrisée : premiers résultats d’une expérimentation menée en milieu rural (Grande Plaine, commune de Gros-Morne, Haïti)

Abstract : This article presents an experiment on the management of a domestic sanitation device by dry litter toilets (TSLB), carried out in rural Haiti. This technology was chosen because of its affordability for the population concerned, in an area where the main practices are those of very simplified latrines (simple holes in the soil) and of defecation in open air. Several actions have been carried out: organization of hygiene awareness meetings, training workshops on the construction of toilets, consultation meetings to establish the needs of the populations in terms of domestic sanitation, their selection criteria, to discuss the availability and preparation of absorbent litter, the necessary equipment, the conditions for the management and treatment of liquid (direct individual use in personal gardens) and solid (choice of composting) residues. The experimentation began with the manufacture and delivery of 25 toilets modules to the pilot households, the selection of the collective composting site and its management conditions. Having opted for voluntary input and community-based management of residues, households bring their buckets there weekly. After one year of operation and monitoring, nearly 4 tons of solid residues were collected. Most of the households bring their residues very regularly and have completely adopted this method of sanitation. This encouraging result now justifies the implementation of an experimental program aimed to optimize the composting conditions to ensure the production of a good quality and hygienizided compost dedicated to be used as an organic amendment for agricultural soils.
