Reaproveitamento urbano de águas pluviais: o caso de uma escola em Silvânia-GO

Abstract

To save water, there are conventional and unconventional measures. The rainwater recovery system is not a conventional measure. Currently, many countries such as the United States, Germany, Australia, Japan and others are using rainwater reuse. The feasibility of using rainwater is characterized by the reduction of water demand by the supply company, which reduces the cost of drinking water and reduces the risk of flooding due to heavy rains. In the rainwater reuse project, impermeable areas are generally used, such as roofs. Rainwater is collected through gutters, vertical and horizontal pipes and stored in reservoirs. Such devices will be dimensioned in this project to serve a school in Silvânia-GO, the collected and stored water will be used for washing the external areas and cleaning the sports court. At the end, a calculation is made using a simple method to assess the cost-benefit of installing the system. Proving how effective the rainwater reuse method can be both economically, environmentally and socially.
