Abstract	El objetivo es describir la situacion de cobertura y calidad del agua para consumo humano, ACH y disposicion de excretas, o aguas residuales ordinarias, en Costa Rica al ano 2007. Para cumplir con el objetivo de este estudio descriptivo-retrospectivo, se aplicaron los siguientes pasos: A. Se aprovecharon los datos historicos de los Programas de Vigilancia y Control de la Calidad del Agua, desarrollados por el Laboratorio Nacional de Aguas, LNA. B. La informacion existente sobre la cobertura de los diferentes mecanismos de disposicion de excretas en el AyA, OPS e INEC. C. La evolucion de las coberturas de agua de calidad suministrada por los diferentes administradores de los servicios de agua potable, se elaboro mediante los informes anuales de calidad del ACH entre 1989 y el ano 2007, elaborados en el Laboratorio Nacional de Agua, LNA. Los resultados indican que Costa Rica tiene una cobertura de ACH del 98.3 por ciento en el 2007, de la cual el 94.3 por ciento es suministrada por conexion intradomiciliar. El 83.5 por ciento del ACH suplida por acueductos fue de calidad potable, mientras que el 82 por ciento de la poblacion total del pais recibio agua de calidad potable. En el caso de la disposicion de excretas, el 67.3 por ciento de la poblacion lo hacen por medio de tanques septicos, el 20.1 por ciento por alcantarillado sanitario sin tratamiento, el 4.9 por ciento por alcantarillado sanitario y tratamiento con operacion deficiente; ademas, solamente el 3.5 por ciento de las excretas son evacuadas por alcantarillado con tratamiento eficiente. El 3.4 por ciento lo hacen mediante letrinas. Se recomienda ejecutar el Programa Nacional de Mejoramiento y Sostenibilidad de la Calidad de los Servicios de Agua Potable 2007-2015. Con respecto a la evacuacion de excretas, es necesario crear un Programa Nacional de la Disposicion de Excretas 2008-2020. The objetive of this study is to describe the quality of water for human consumption (ACH ), excrement disposal, and sewerage water in Costa Rica, as well as their coverage to the year 2007. In order attain the objective for this descriptive and retrospective study, the following steps were applied: A) Analysis of the historical database from surveillance and water quality control developed by the National Water Laboratory (LNA). B) Analysis of existing information regarding coverage of different mechanisms for excrement disposal in AyA; Pan American Health Organization, and the National Institute for Statistics and Census (INEC). C) Coverage evolution of water quality supplied by drinking water services administrators, which was done by means of annual reports of quality of ACH between 1989 and 2007 as reported by the National Water Laboratory (LNA). The results indicate that Costa Rica has a coverage of ACH of 98,3% in 2007, of which which 94.3% is supplied by household connections. 83.5% of ACH supplied by AyA was drinking water quality, while 82% of total population of the country was supplied with drinking water quality. In the case of excrement disposal, 67.3% of population used septic tanks, 20.1% by sewerage system without any treatment, 4.9% by sewerage system with a poor treatment of sewage water; furthermore, only 3,5% of excrements disposal by sewerage systems are treated with efficient treatment, and 3.4% use letrines. We recommend carrying out the National Programme for Improvement and Quality Sustainability of Drinking Water Services 2007-2015. With respect to excrements disposal, it is necessary to create a Program of National Excrement Disposal 2008-2020.
