ADEQUAÇÃO DO SISTEMA DE MICRODRENAGEM URBANA NA SUB-BACIA DA LAGOA SECA NO MUNICÍPIO DE BOA ESPERANÇA - MG

Abstract

The microdrainage system is extremely necessary for a perfect drainage of rainwater. This system is designed to retain and conduct water to appropriate locations to avoid problems such as erosion of roads and flooding the road gutter. This study examined the technically microdrainage conditions in the allotment of the New Age neighborhood, specifically in the Lagoa Seca sub-basin in Good Hope, with basement to the theoretical aspects, and contained in literature. His focus was on the puddling of water on the streets Teixeira Olinto, Senator Milton Campos and Princess Elizabeth, who often suffer from the problem. They were collected all the necessary data for determining the flow generated in the study area section such as the contribution basin, precipitation intensity, return time, concentration time, among others. Thus checking the efficiency of existing mouths-of-wolf in the basin resulted in a capacity of less efficient than necessary to flow contribution. It can be proved that due to the lack of a micro drainage system in study sections, the flow of contribution basin that does not drain accumulates at the lowest point of the basin causing flooding. The paper presented a comparison between two solutions to the problem, in which the first was made use of a reservoir holding and lifting system that had a cost of R $ 1,030,949.19 and the second solution was to use a gallery where it was not possible to follow the slope of the land, with a cost of R $ 894,159.34. Then, after choosing the most viable solution, making deployment microdrainage devices that have become necessary, it is expected that problems with flooding and waterlogging on site are healed.
