Análise das perdas no sistema de abastecimento de água da cidade de Delmiro Gouveia – Alagoas, considerando dados de 2018, 2019 e 2020

Abstract

Water is an abundant natural element on the planet, and essential for the existence and survival different forms of life, a fact that makes access to safe drinking water one of the fundamental resources for human existence, in addition to being a good in the public domain. However, it is a limited resource, and one that is increasingly scarce. Based on this concept, knowing that the supply of quality water must be a priority, and that the high rate of real water losses has been an aggravating factor within sanitation companies, an internal program to manage and combat losses is of fundamental importance in which the preservation of water sources and the control of the quality of water for consumption are obtained. Within this context, the present work studies water losses in the supply system of the municipality of Delmiro Gouveia, located in the Alagoano sertão, through the analysis of indicators of water losses in public supply networks used by the service provider CASAL in the years 2018, 2019, and 2020. The losses presented rates of high values, and a significant increase between years, however, it is noteworthy that this increase does not necessarily indicate fewer losses in the previous years, since in the approach from the calculation of losses from 2018 to 2020, changes occurred in the way of measuring the data taken into account in the calculation of volumes, consequently on calculating the losses. These changes represent, in a way, an improvement in management and greater control in relation to the real value of losses.
