Drenagem Urbana: qualificativo de dispositivos de drenagem no centro urbano de Corrente-PI

Abstract

In many cities, urban drainage infrastructure does not keep up with urban growth or climate change, so analysis provides in-depth insight into how drainage devices work. The objective of this research is to identify and evaluate the urban drainage devices responsible for collecting rainwater from existing streets in the urban area of Corrente-PI, identifying the main problems related to urban drainage in the researched area. The mapping and evaluation of the operational conditions of the manholes was carried out, initially, through the Greatracker application that uses GNSS (Global Navigation Satellite System) navigation, in which it was possible to collect the latitudes, longitudes and altitudes of each equipment under analysis. The analysis of the gutters considered dimensions of height, width and transversal slope. The conservation conditions of the rainwater collection devices were evaluated, highlighting the areas that showed need for maintenance or reinforcement in the infrastructure. The implementation of a structured drainage plan and the recruitment of professionals involved in rainwater management can contribute to minimizing the problems identified and increasing the resilience of the urban infrastructure to extreme/unexpected events
