Resumen

El número de proyectos de recarga artificial (MAR) en Australia se la incrementado en los últimos años, en parte como respuesta a la sequía y al crecimiento de la población en las ciudades. Las aplicaciones de esta técnica en las ciudades se han realizado infiltrando agua depurada o agua procedente de tormentas en los acuíferos para su posterior utilización para el riego urbano, el uso en inodoros o el uso industrial. El suministro de agua de bebida está empezando también a utilizar estas técnicas. En zonas rurales, también se almacena el agua depurada y el procedente de tormentas en acuíferos durante la estación húmeda para suministrar agua para regadío en la estación seca. Para facilitar todas estas operaciones, se han redactado directrices a nivel nacional para la gestión de la recarga artificial, que se han complementado con documentos de discusión sobre los aspectos políticos y legales involucrados. Sin embargo, aún quedan aspectos que mejorar, sobre todo para integrar la recarga artificial en la planificación e infraestructuras de abastecimiento urbano, así como para determinar su viabilidad en la gestión de los recursos hídricos subterráneos en sistemas con importantes descensos de los niveles piezométricos. Este artículo describe algunos de los procedimientos desarrollados, así como la información disponible para ayudar a usuarios y legisladores sobre los proyectos MAR.
