This study aimed to evaluate the linear correlation between data from four rainfall stations for the design of a rainwater harvesting system for non-potable purposes in a municipal public school in Teófilo Otoni, MG. First, a cartographic study was carried out using a geographic information system environment in order to generate a map with the rainfall stations and the school where the collection system was designed. Next, an attempt was made to assess the availability of data present at the stations and compare them using linear regression. Finally, the design of the rainwater harvesting system for the school was carried out. The results of the linear correlation indicate that the four stations can be used in the sizing of the system. Finally, the implementation of the system can contribute to the reduction of water consumption and, consequently, financial expenses.Downloads
