Diretrizes para implantação de sistema de captação de águas pluviais pelas indústrias cerâmicas no agreste pernambucano

Abstract

The ceramic industries use water to humidify and work the clay in the production line, with the water deficit that occurs in the Agreste region of Pernambuco, a region that have suffered with this problem for hundreds of years, it is imperative to study options that minimize the impacts caused by periods of drought. Rainwater harvesting for use in the production line of the red ceramic industries is an unconventional form of water conservation. The present study aims to establish the guidelines for the implementation of a rainwater harvesting system. Its use has several advantages, the main one being the environmental one, reducing the consumption of the water of the sources, the expense with the transport and the reduction of floods through the reduction of the water thrown in the system of drainage of rainwater and the economic one by a smaller consumption of water supplied by Sanitation Companies and other suppliers. In this paper, we present the results of a study of the climate of the region and the follow-up of the case study in the Red Ceramic Industry, located in Caruaru, where the capture system was implemented, using the existing structure, a set of guidelines elaborated to implement the system. In this proposed guideline, the use of existing structures and the design of the system, the control of water quality and the ways of raising awareness among users and their involvement in water conservation were evaluated. With the study area within a region with great vulnerability and climatic variability, results have been obtained which lead to the conclusion that the use of rainwater is a practice that should be encouraged in all regions and in both industrial and domestic activities.
