AUTOMATION OF A WATER SUPPLY SYSTEM FOR RESIDENCES

Water scarcity is increasingly haunting the world, and the outlook for the next few years is not enough for everyone to drink, thanks to the pollution and waste that grows every year for a population growing more and more on the globe. Water scarcity is not the only problem we face. In Brazil, the country with the largest freshwater reserve in the world, another major problem is the supply of water in the cities, in several regions the population faces an inefficient supply system, which presents faults in the water course the residence. The present work proposes an improvement in the residential water supply system that uses hydraulic pumps, automating the process of feeding the reservoirs of the residential, developing an autonomous system allowing the user to have control of the supply process in their property. The importance of the work is made by the difficulty encountered by residents of regions that suffer from the irregular water supply in their homes. The work was based on an experimental research, starting from a bibliographical research in several literatures as academic papers, researches and articles, focused on the study on water supply, hydraulic systems and automation. The studies were based on a residence in the northern part of Manaus/Amazonas, where there are irregularities in the water supply in this region, causing residents to use hydraulic systems to supply their residential reservoirs. In addition, a prototype for better observation of the automated operation of the small-scale supply process was developed for the study to perform better. Through an existing hydraulic system in the house, the automation process was carried out by the elaboration of an electrical system with the function of activating the pump through an Arduino® and for indicate the sensors responsible for the level of water in the reservoirs. A simple and practical monitoring system was developed based on an electrical principle and a hydraulic system. After the tests carried out, the model proposed in this work showed a simple and functional hydraulic supply system, facilitating for the user the monitoring of the water supply operation for the residence, the project was elaborated using elements already existing in the residence in order to reduce costs for the user, an autonomous system was implanted in the water supply process of the residence, thus enabling practicality in the activation of the hydraulic pump and the monitoring of levels in the reservoirs of the residence.
