This paper seeks to propose rational water use indicators for public schools in Recife, Brazil. The methodology consists of a cadastral survey, the use of questionnaires, and identification of leakage in the hydro-sanitary facilities. The results indicate that even though water consumption is not as high as pointed out in the literature, the schools still present a considerable amount of physical water losses, in addition to having a low perception regarding the rational use of water. Based on these results, this study supports the development and application of water conservation actions within the school environment.
