Drinking water is a limited resource, and if systems that can maintain its regular cycle are not used, misuse can generate its absence and scarcity on Earth. Its use needs to be conscious and rational, respecting criteria of sustainability and economy. In this sense, a study aimed at environmental sustainability at the Instituto Federal de Alagoas (IFAL), Maceió campus, was carried out; thus, a proposal for the use of rainwater was studied in order to use it to refill the unit's sports pool. The refilling of this pool is responsible for part of the water consumption of the campus, as it has the dimensions of a semi-Olympic pool, the demand to refill it is significant. After research it was found that the average annual precipitation, in the period from 2016 to 2021, is 1,425.34 mm. For rainwater catchment the building corresponding to the IT block was defined, which has a catchment area of approximately 357m². From these data it was possible to calculate the average monthly catchment potentials for the coverage area, besides the total rainwater demand calculated for the refilling of the swimming pools, equivalent to 160 m³. It was concluded that the English Practical Method presented the smallest reservoir among all the methods calculated, and also proved to be compatible with the space available for the location of the reservoir, and also with the potential for monthly rainwater catchment. Thus, the system's reservoir volume was set at 30 m³. Next, the operation of the rainwater harvesting system was determined, which presented the need for investments in equipment and labor that would make the campus more expensive; however, it is a harvesting alternative in cases of future deficits. Finally, some recommendations were presented for future studies aiming at the viability of rainwater harvesting at IFAL-Maceió.Acesso AbertoÁguas da chuvaSustentabilidadePiscinaPrecipitação médiaRainwaterSustainabilityPoolAverage precipitationTrabalho de Conclusão de CursoENGENHARIAS
