Estudo de aproveitamento de água de chuva no condomínio Dona Lurdes Piacentini em Campo Mourão - PR

Abstract

Due to the water shortage problem observed worldwide, it’s important to seek alternative means to supply the population. The collection and storage of rainwater is a simple technique used for centuries, mostly for non-potable purposes. The estimation of rainwater volume for common use is based on catchment areas and atmospheric precipitation data. The objective of this work is the Dona Lurdes Piacentini residential area located at the city of Campo Mourão-PR. This residential area has a drainage system problem, which doesn’t tolerate considerable amounts of rainfall in a short period of time, hence part of the land gets flooded. The aim of this project is to dimension a reservoir to collect rainwater and estimate the amount of treated water saved due to the creation of this reservoir. The collected water is going to be used for non-potable purposes. A Sanepar consumption data was consulted and analyzed throughout the months of April and August of 2017. The use of water for courtyard cleaning and mensal consumption were estimated. This project found that the implantation of a harvesting rainwater system will solve the drainage system problem and has a 15-year return period, approximately. The system is economic viable and is a sustainable technic which will decrease the treated water consumption.
