Avaliação do sistema de microdrenagem na rua Ipiranga, na cidade de Corrente, Piauí

Abstract

Urban drainage is used to manage rainwater to prevent flooding and inundation in urban areas. However, when planned without proper study, the rainwater collection system becomes incapable of draining all the precipitated liquid, resulting in excessive accumulation of rainwater on public roads. In this context, the main objective of this study is to evaluate the devices that make up the microdrainage system on Ipiranga Street. The methodology used involved a qualitative and exploratory approach, complemented by bibliographic research and field study. Data collection occurred in two stages: the first on sunny days, to identify obstructions and anomalies in the drainage system, and the second on rainy days, to monitor the occurrence of flooding. The results obtained indicated that the microdrainage system has deficiencies that compromise its efficiency. Obstructions were identified in manholes and gutters, in addition to damage to the asphalt pavement that interferes with the flow of rainwater. It is clear that the inefficiency of the microdrainage system on Ipiranga Street, aggravated by the obstruction of the devices and damage to the pavement, contributes significantly to the occurrence of flooding in some places in the studied area. Thus, the study emphasizes the need for maintenance actions and improvements in the drainage system, with the intention of ensuring the adequate management of urban rainwater
