Utilização de círculo de bananeiras para destinação de águas cinzas em ocupação urbana de João Pessoa-PB como contribuição para o saneamento básico

Abstract

The sanitation problem is one of the results of urbanization that excludes peripheral populations, especially those in urban settlements. The Banana Circle was a technology used in this action research in the Terra Nova Community, in João Pessoa, because it is a low-cost technology that can be implemented by the community itself, and can be easily appropriated and provide the capacity of populations in precarious conditions to overcome inequalities such as basic sanitation. The aim was to understand the contributions of the use of this technology to the construction of a critical view of the importance of sanitation, especially in relation to the correct disposal of greywater. To do this, it was necessary to understand the history of the local population with the environment in which they live; document the situation of greywater discharge in the community; analyze the quality of domestic effluents in the local community; and apply the use of Banana Circles as a viable alternative to the lack of basic sanitation. This action research observed that the retention of wastewater in banana circles improves the quality of life by removing this water from the surface of the soil, avoiding bad odors and disease vectors, in addition to preventing a large amount of nutrients from reaching aquatic ecosystems, preventing their eutrophication. Therefore, it should be used both as a tool to raise awareness among the population regarding ecological processes, and as a practical action to improve their living conditions.
