Proposal for sustainable drainage for a small municipality - Case study

Abstract

Currently the concern regarding the renewal and preservation of natural resources promotes studies that relate the reduction, reuse and recycling of these resources. Civil Engineering, specifically the Urban Infrastructure sector, has responsibility for the preservation of ecosystem of urbanized areas and in process of urbanization. Urbanization should be carried out in a way that promotes the reduction of environmental impact and the application of measures that preserve the Permanent Preservation Areas, use the areas properly, preserve the water sources, handle rainwater and allow groundwater recharge, treat effluents, among others. In this context, the aim at this study is to propose a sustainable drainage system for downtown area of a small municipality. Case study has an area of 280.8 km² and two scenarios of urban, conventional and sustainable drainage. Development has seen the use of measures that preserve and reuse water resources, reduce diffuse pollution and promote the recharge of groundwater. Concluded that when adopting sustainable measures for urban drainage there is a reduction of runoff’s coefficient areas and of the rainfall released in the drainage system.
