Análise quantitativa das primeiras águas de chuva para fins não potáveis na cidade de Delmiro Gouveia - AL

Abstract

In view of the disorderly population growth in urban centers which entails negative consequences, such as lack of natural resources, water becomes increasingly makes it a limited good. Therefore, studies are needed to address new techniques for the economics of drinking water consumption with a view to preservation and conservation, thus, rainwater harvesting systems They are a cheap and sustainable technology. The present work evaluates the reliability mm first flush quantity of rainwater for non potable purposes in the city of Delmiro Gouveia, Alagoas. Initially, data were analyzed monthly, annual and daily rainfall as well as the correlation between areas of roof used as a catchment area with demands regarding the consumption of residents. They were divided into real and hypothetical scenarios in order to obtain the more accurately local reality. For all cases, volume calculation of the reservoir through the simulation method where it is possible to reach levels of fault-based reliability. As a result it can be considered that the volume of the first rainwater can be stored in small reservoirs, even with high failure rates, as they can be of service if tied to conventional systems.
