Análise quali-quantitativa de água perdida por vazamentos da Estação de Tratamento de Água (ETA) setor bairro Tancredo Neves da cidade de Paulo Afonso – BA

Abstract

Water is a vital resource for living beings, so it is essential that it goes through a treatment process that makes it potable. However, in this process of potabilization, it ends up being wasted due to innumerous factors that may start from the abstraction in the springs to its distribution, a subject that has been frequently pointed out by several authors. Thus, this paper presents quantitative and qualitative data of treated water lost through leaks in the Water Treatment Station of the BTN sector in Paulo Afonso - BA, managed by the Empresa Baiana de Águas e Saneamento (EMBASA) with a treatment potential of 150 L/s and responsible for supplying several neighborhoods of the city. Therefore, a field and laboratory research was carried out in order to calculate the average volume wasted daily and make a comparison with the number of local inhabitants who do not have access to drinking water, besides certifying if the discarded water was ready for human consumption by performing turbidity, color and pH tests in the chemistry laboratory of the Federal University of Alagoas - Campus Sertão in Delmiro Gouveia. Then, an average volume of more than 530 m3 of water was detected to be wasted per day and with standards within what is required for human use. Therefore, carrying out repairs to the structure in order to contain the leaks, in addition to modernized measures to control losses, such as management plans with performance indicators, are solutions to solve the problem in a short and long term.
