Avaliação de quatro pontos de lançamento de emissários de galeria de águas pluviais contribuintes do Rio do Campo no município de Campo Mourão, Paraná

Abstract

The current reality of urban environments indicates that it is vital for city and town managers to establish plans and strategies aiming to control and redirect rainwater to the receiving water bodies, as issues caused by rains accumulate, such as flooding, inundation, soil erosion and deterioration of urbanized areas. The proper design of the urban storm sewer systems has as benefits the rapid and efficient removal of rainwater from urban centers, consequently increasing the comfort and safety of the population, and reducing environmental impacts. Based on the previous arguments, the main objective of this work was to analyze the design and the current conditions of four final storm sewer outfall pipes whose flows contributes to Campo River in the municipality of Campo Mourão, Paraná, by redesigning the fractions of the storm sewer network connected to the four outfall pipes and by observing the conditions of their building, preservation and maintenance. It was observed that all analyzed outfall pipes presented problems related to the building or maintenance procedures and that 50% of the outfall pipes have inaccurate final diameter, indicating problems with the original design.
