Análise de viabilidade do aproveitamento da água de chuva em um prédio público, na cidade do Recife- PE

Abstract

Rainwater harvesting can be a quick way to obtain large volumes of water of reasonable quality. Most cities throughout the state of Pernambuco, including those in the Metropolitan Region of Recife - RMR, experience difficulties every year to ensure the public supply of drinking water. Therefore, the use of a rainwater harvesting system is an alternative to reduce the demand for treated water. This work analyzes the feasibility of building a rainwater storage reservoir at the IFPE campus - Recife. In this context, an arrangement of information was necessary to generate data and support the feasibility analysis. For this, local rainfall data, definition of the catchment area, and demands for non-potable water uses were analyzed. It was observed that the implementation of a reservoir for the use of rainwater is viable in the studied area, since the payback indicator was in a period of approximately 1 year 5 months.
