Estudo e proposta de implementação de sistema para uso racional de água em empresa de transportes no norte do Paraná

Abstract

This study provides guidelines for the implementation of a program related to the rational use of water, by piloting a case study in a collective transport company in the north of the state of Paraná, Brazil. The objective of this study is to provide opportunities to reduce the use of potable water in the built environment, highlighting the use of rainwater harvesting as an economically viable alternative. This study encompassed an overview of water conservation programs in existing buildings, of ways to reuse wastewater, of details of components of a rainwater harvesting system and related regulations. At the end it was proposed a system to collect rainwater for washing the company's transportation vehicles; as well as by implementing actions to reduce the water consumption by its users. This study showed through an economic analysis that it is possible to significantly reduce the consumption of potable water, achieving an immediate reduction in costs, which will settle the employed investment in the system in a few years. In addition, this study showed that socio-environmental benefits will be also generated.
