Eco-cisterna: desenvolvimento de uma solução de automação para coleta da água pluvial em ambiente residencial

Abstract

The availability of water for drinking and non-potable use is an essential component of human life and its rationalization combined with a conscious use is a recurrent theme for the entire planet. This work aims to develop a product capable of managing the collection, treatment and use of rainwater collected for automatic non-potable use. In the current market of products for rainwater harvesting for residential and commercial consumers, there are numerous solutions that present the predominance of manual processes and low presence of automated solutions, being the human intervention intense in this process. With the possibility of innovation in this group of products, this work proposes the development of a prototype of a commercial product that automates relevant processes in the collection, treatment and use of rainwater. Additionally, by using several actuators, sensors, and embedded software technologies, the management of the tank’s water volume is done autonomously. During the development of the prototype in question, unit, functional, nonfunctional, compliance, and user tests were performed according to the product requirements. The product presented satisfactory results, even with the difficulties and the various functionalities proposed. This prototype has high relevance for the automation of processes related to the collection, treatment, and use of rainwater, because it enables the automation of a relevant process considering the planet’s socioeconomic environment.
