Uso de água pluvial para fins não portáveis em hotel fazenda localizado em Sairé - PE

Abstract

The objective of this work was to propose the reuse of rainwater, at the Hotel Fazenda Monte Castelo, in five areas, called, A1, A2, A3, A4 and A5, as a sustainable measure to reduce the consumption of drinking water through the concessionaire. Initially, a bibliographical research was carried out with related themes, technical norms and calculation methods for reservoir sizing and estimation of the drainage capacity of the roofs. The study was directed to the use of rainwater in Areas A1, A2, A3, A4 and A5 of Hotel Fazenda Monte Castelo located in the city of Sairé-PE. The use of rainwater is a low-cost reality with high expectations of return on the economy. The total volume needed to capture rainwater is 1,600.00m³ for a demand of 1,890.00m³ and 10,841.05m² of catchment area following the Rippl method. The specific reservoir for discarding the first waters is approximately 12.00 m³. The study points out that 64.00 liters of chlorine will be needed to disinfect the collected rainwater and that there will be an average monthly saving of 81.00% in the consumption of drinking water. The technical and environmental viability of the study for execution in projects in the region was verified.
