Sistema de microdrenagem urbana para o bairro centro no município de Pombal- PB.

Abstract

The objective of this study is to develop a technical urban microdrainage project for the Centro neighborhood in the municipality of Pombal, Paraíba, aiming to mitigate the frequent flooding problems resulting from soil impermeability and the lack of an adequate drainage system. The research uses analysis of the current drainage system and hydrological analysis of the area, on-site visits, as well as characterization of the area and land use and occupation. The methodology integrates the use of specific software: QGIS for mapping and delimiting the study area, AutoCAD for laying out the drainage network, and Excel for calculating the sizing of the devices. The results show that the current system is deficient, with blocked storm drains, silted channels, lack of maintenance, and illegal sewage connections to the storm drain network, compromising hydraulic efficiency and environmental quality. The proposed solution includes the design of gutters, storm drains, and galleries, following technical criteria from drainage manuals and auxiliary ABNT standards, ensuring greater drainage capacity and safety during heavy rainfall events. It is concluded that the implementation of the proposed system will reduce flood risks, contribute to the preservation of urban infrastructure, and improve the population's quality of life. It will also serve as a technical basis for future urban planning and public policies focused on sanitation and sustainable stormwater management.
