ANÁLISE DA EFICIÊNCIA HIDROENERGÉTICA E DIMENSIONAMENTO ECONÔMICO DO SISTEMA DE RECALQUE DE ÁGUA BRUTA DO RIO MUMBABA PARA O RIO MARÉS, LOCALIZADO NO MUNICÍPIO DE JOÃO PESSOA-PB

Abstract

The water system from the Mumbaba River to the Marés River is part of the water supply program of the city of João Pessoa-PB and adjacent regions. Based on the former studies, it is possible to visualize some problems that hinder the full capacity of the current system, such as: the low flow rate of water promoted at the expense of a high energy expenditure, as well as the need to pump the Gramame River water beyond permitted by law. This work aims to make diagnoses of these problems and propose a new project more efficient hydroenergetically, rentable and committed to the environment. Based on the study of the current system and its inputs, the associated bibliographic about the theme, two new sets of motor pumps (CMB) were dimensioned and replaced those currently used by the Paraíba Water and Sewage Company (CAGEPA). With this change, the flow rate reaches about 500l / s - which is equivalent to 143% of the current flow, operating under the same energy expenditure of the operating sets. An economic analysis of the proposed project was also performed and saw that the benefits outweigh the costs. In addition, due to other problems encountered, some changes were suggested in order to improve the functioning of the current system
