Alternativas para el manejo de excretas de la comunidad de San Rafael, parroquia Checa.

Abstract

The objective of this study is to evaluate two sanitation technologies for the management of excreta in the rural parish of San Rafael - Checa, considering that the community has poor sanitation since they do not have adequate facilities for disposal. Within the community, families have cesspools, which are rustic infrastructures that do not have any type of waterproofing coating or disinfection system for viruses and bacteria inside that prevents the passage of pathogens into the soil or prevents seepage of wastewater, causing contamination in the soil and water that is used in the community, compromising the health of the inhabitants. Faced with this problem, two sanitation technologies were proposed that can be used in the community in the future, the biodigester and the composting latrine. To determine the ideal technology, the decision matrix was applied, which takes into account technical, social, environmental and economic factors. As a result, it was obtained that the biodigester had acceptance of 71.66%, where technical factors represent 34.66%, social factors 12%, environmental factors 11% and economic factors 14% of the total. While the composting latrine had a final rating of 77.22% within the community, of which 38.22% represents technical factors, 12% social, 13% environmental and 14% economic. Therefore, it was concluded that the latter is the ideal technology for a future application in the community.
