A utilização do sistema de informação geográfico (SIG) como ferramenta de gestão na distribuição da rede de esgoto no conjunto João Sampaio II

Abstract

Geographic Information Systems (GIS) play a crucial role in the planning and decision-making processes of sanitation utilities, enabling more efficient management of resources and services. This study investigated the use of GIS in the context of the residential complex João Sampaio II located in the Benedito Bentes neighborhood in the city of Maceió, Alagoas, highlighting its potential as a tool to assist basic sanitation companies. The methodology employed involved the collection, processing, and correlation of commercial data related to domestic sewage boxes, using the QGIS software. The data from the sewage networks and their structures were also considered. Based on the attributes contained in the constructed database, the data were categorized by colors, and thematic maps were created. The results revealed that 88.57% of the properties have water meters, while 11.43% do not yet have them. Furthermore, it was found that 93.21% of the properties have active sewage connections, while 6.79% are inactive. It was also observed that the residential complex is predominantly residential. This research generated maps, graphs, and analyses that can support future decision-making by the sanitation utility, as well as facilitate the execution of works by companies interested in the region, as they will have knowledge of the location of the pipelines, thus avoiding undesired damages. These spatial information provide valuable data for the planning and improvement of sanitation services, meeting the specific needs of this residential complex and contributing to more efficient management.
