ANÁLISE DE VIABILIDADE: sistema de captação e aproveitamento de água pluvial em condomínio residencial na cidade de Varginha - MG

Abstract

Drinking water is an extremely important natural resource for human survival, but it is often used for non-noble purposes that result in waste. Following this line of thought, and also addressing the economy of financial resources, flood reduction, and the solution for water lack, the use of rainwater is a method that minimizes these effects, and also helps to reduce the consumption of drinking water for non-noble purposes. The current work, therefore, focuses on analyzing the feasibility of implementing a water reuse system for the condominium Portal Jardim do Sol II in Varginha - MG. The research started with the search of bibliographies and materials so that theoretical concepts could guide the development of it. After that, it was followed by the data collection, the rainfall and capacity rates of the prospected site, as well as the dimensions and features of the construction. By the relationship between the theoretical knowledge applied to the obtained data, the next step was to plan the destination of the retained water and its impacts on the current structure, analyzing the economical and constructive viability, besides the system return rates. Given that, it’s possible to conclude that the condominium Portal Jardim do Sol II, which has 6,646.58 m2 of catchment area, distributed throughout the roofs of its 19 towers, generates an average monthly volume of rainwater of 715,615.11 liters, which is enough to equate and overcome the current demand of 449,988.50 liters, validating the feasibility of the system implementation.
