PROPOSTA DE PROJETO DE CAPTAÇÃO E APROVEITAMENTO DE ÁGUA DE CHUVA: Estudo de Caso na Escola Municipal Edna de Abreu – Três Pontas, MG

Abstract

Water presents itself as an essential resource for life and every day many regions suffer from its scarcity or contamination. Emphasis is thus placed on the concern with its preservation and conservation, a topic that is much discussed today. This paper presents a proposal for the rational use of water through the rainwater harvesting system, in order to promote sustainability. The objective of this work is to propose a rainwater harvesting project for non-potable purposes in a public school teaching institution in the municipality of Três Pontas, MG. It was necessary to establish parameters according Regulatory Norms. Afterwards, the average precipitation and rainfall intensity of the study site and the volume of roof capture were estimated, in order to determine the demand and safely size the collection system. The design of the lower reservoir was carried out from the consumption at the chosen points, and the water was raised to the upper reservoir through a lifting system and distributed to the points of consumption by the distribution network and thus to find the saving of drinking water that the municipality would reach in the school in study and also raising the economy that he would reach with the installation in all the municipal educational institutions.
