Abstract

The rational use of drinking water has been a cause of concern in today's society. A number of policies have been adopted with the purpose of raising awareness of the population and legal provisions have been created to reduce waste and implement alternative sources for purposes less noble than intake. In this sense, the objective of this work is to show the optimization and automation project of the use of rainwater and the effect of the monitoring of the consumption of drinking water implanted in a technical school of the federal network. As a result, it is verified that the utilization of rainwater corresponds to one third of the total water consumption in the period investigated after the implementation of the project. Allied to this, also a noticeable reduction in the consumption of drinking water, independent of the utilization of the rain water. From the economic point of view, there was a considerable reduction of the drinking water bill paid by the institution after the project was implemented.
