Sugestões de redução de consumo de água em um hotel localizado em Bagé

Abstract

Today, the need for water conservation is highlighted, and it is increasingly necessary to seek sustainable measures and solutions that contribute to the rational use of water. In these sustainable solutions, rainwater harvesting techniques stand out, thus verifying the importance of knowing studies already carried out by other researchers, proving that the potable water saving potential obtained through the use of rainwater is quite important. expressive. In some regions, this use of rainwater becomes even more important due to water scarcity, such as in the city of Bagé - Rio Grande do Sul. Checking this situation, the idea of carrying out this monograph in a hotel, located in the city, emerged Bagé, aiming to reduce the consumption of drinking water and use rainwater. The methodology proposes the calculation of the hotel's water consumption and the dimensioning of the rainwater reservoir using the NBR 15527/2019 method and the Aquasave method. The results suggested many changes to reduce water consumption, such as the use of aerators, replacement of conventional faucets with self-closing faucets, the use of toilets with attached boxes and a rainwater harvesting system. The rainwater harvesting system provides for the replacement of drinking water in the laundry (4136 L) and in the hotel cleaning (4050 L) with rainwater, collected in the 102.5 m2 of roof coverage. This replacement generates savings in the monthly water bill of approximately 40% and also generates the marketing of a nature-friendly hotel.
