Evaluating dry toilet use in a rural area of Colombia.Fifteen families were selected by convenience sampling from the rural area of a municipality in the Cundinamarca department in Colombia. A dry (composting) toilet was installed in one house and used for demonstration purposes over a five-month period. An ex-post evaluation was made concerning technical and economic matters.A dry toilet is easy to construct/install and has environmental benefits associated with less contamination of water sources reduction and a reduced amount of chemical fertilizer. Dry toilets construction and operating costs may represent savings of Col$616973456 (US$308487) in the municipality being studied, compared to the costs involved in conventional toilet use. However, cultural barriers were found regarding their use.A large percentage of households in many countries rural sectors do not have a sewerage system for disposing of human waste. This situation creates significant challenges regarding environmental health and ecosystem conservation. Dry toilets represent an environmentally-acceptable solution from a technical and economic perspective; however, work is required concerning social and cultural factors producing cultural perceptions and prejudices about handling excreta to provide the necessary coverage and produce a significant impact on peoples awareness.
