Environmental conservation and sustainable development by civil construction have driven the population to adopt new practices, especially those aimed at reducing environmental impact. With increasing urban growth, the green areas are becoming scarcer in the scene of many cities and society awareness for the rational use of water, conservation and reuse are becoming increasingly important. The use of green roofs can be seen as one of the main techniques to mitigate the problem situation as it increases the amount of green areas favoring ecological aspects and, especially, the use of rainwater. The reason is that in this type of covering, a large part of the rain water seepages and can be reserved, which makes its use possible. This survey was conducted in a northern higher education institution of Rio Grande do Sul in order to qualitatively assess the rainwater captured in green roofs prototypes and compare it with the water collected in another container, considering physical and chemical parameters for non-potable uses. Through the analysis of the samples collected, it could be seen that the results did not show a correlation with each other, comparing the initial expectations of the project and leading to the conclusion that the rainwater collected by the green roofs must pass, first, by an appropriate treatment before the use for no potable purposes.
