Análise de sistemas de gestão de águas residuais em escolas localizadas em zonas com solos de baixa permeabilidade e elevado lençol freático. Estudo de caso: Escola Secundária Eng. o Filipe Jacinto Nyusi

Abstract

After the family environment, school is the place where pupils spend most of their time. For this reason, adequate sanitation and hygiene conditions help to maintain the integrity and health of the pupils. Wastewater drainage systems are sanitation, so it is also necessary to look at this issue. issue. Due to the diversity of the terrain, geographical, geotechnical and hydrological conditions, the conditions in which schools are built differ for each site on which they are built. implementation. The implementation of wastewater management systems that are suited to the the conditions of the land on which the schools are to be built and/or are built generally guarantees the efficient operation of this system. The aim of this work is to analyse the operating behaviour of wastewater management systems. of wastewater management systems installed in schools located in areas with low permeability with low permeability soils and a high water table, and to analyse the the main problems faced by these institutions and to identify alternative solutions that can be used in these situations. The study was based on interviews, laboratory tests and drilling work in the field. drilling work in the field and a literature review. The schools covered by the study use conventional drainage systems, septic tanks and vertical drains. The the study carried out, it was found that the behaviour of the systems differs in each of the institutions. (TRADUÇÃO NOSSA)
