Analysis of the micro-drainage infrastructure on an avenue in the city of Aracaju-SE

Abstract

The urban drainage system plays a vital role in the lives of people living in urban areas, protecting properties and citizens during heavy rainfall, preventing erosion on streets and public roads, and other benefits. To create an efficient drainage system, attention must be paid to the design, execution, and supervision of works by qualified professionals, as well as the maintenance of existing works. Because of the above, this article aims to analyze the micro-drainage infrastructure of Avenida Edélzio Vieira de Melo, in the city of Aracaju-SE. Initially, an in loco visit was made to assess the state of conservation and the presence of waste in the gutters and gutter inlet. It was observed that 51.2% of the gutter inlets are located in an undesirable way; 60.5% are partially or totally degraded and 81.4% have solid waste disposal. About the manholes, 90% are inadequately located, 80% are partially or totally degraded, and, finally, 70% are level with the sidewalk. The conclusion is that the devices need to be cleaned more frequently, and the population needs to be made more aware not to throw garbage in the street, since the presence of solid waste negatively affects the functioning of the drainage network. Finally, the location of the devices (manholes and gutter inlets) affects their efficiency, and durability and interferes with the comfort of those who use the road.
