Dimensionamento de um sistema de captação da água da chuva em uma residência unifamiliar no município de Farroupilha - RS

Abstract

Good quality water is like health or freedom: it only has value when it runs out. The system for capturing and using rainwater is one of the ways to reduce the consumption of potable water in civil engineering projects that are easy to apply and cost-effective. For this, it was proposed the implementation of a system for capturing and using rainwater in a single-family residence, more specifically the use of this water in the toilet bowl and in a garden faucet. Research and sizing were carried out at all stages of the system, such as average rainfall, capture, collection, storage, treatment and pumping to meet the studied demand. Every study was developed in accordance with ABNT NBR 15527/2019, and all the standards it recommended. With the study, it is possible to have a better understanding of rainfall data in the region, months in which the collection is greater, determine monthly and annual consumption volumes, predict collection and extravasation volumes, in addition to predicting the return on investment for implementation. and system operation, this time resulted in approximately 8 years.
