Alternativas para el manejo de excretas de la comunidad de San Rafael, parroquia Checa : Evaluación de alternativas para el manejo de excretas: letrina de pozo anegado y baño de arrastre hidráulico para la comunidad San Rafael en Checa.

Abstract

Basic sanitation is a need that is difficult to meet in rural areas, which is why there are alternatives for excreta management that seek to generate solutions to this problem. The sanitation technologies with flush toilets proposed for the San Rafael community are: the flooded pit latrine and the hydraulic flush toilet. The methodology used was to design a guide for each of the technologies, based on specifications and technical considerations extracted from the Pan American Health Organization, then the unit prices of each sanitation unit were determined by means of quotations in material and labor distribution centers using experts in the construction area, Subsequently, a decision matrix was used to identify the most appropriate technology, which included technical criteria with a weight of 40%, economic criteria with a weight of 30%, social criteria with a weight of 15%, and environmental criteria with a weight of 15%. The result of the evaluation of the technologies gave 51.33% for the flooded pit latrine and 58.11% for the hydraulic drag toilet, these alternatives are not feasible to implement in the community because they do not have an adequate management of the distribution network, low permeability which makes it impossible to operate and the high costs exceed the monthly income received by the inhabitants.
