Análise do sistema de abastecimento de água da cidade de Palmeira dos Índios-AL através de simulação hidráulica

Abstract

Water distribution in Brazil still suffers significant losses, whether real or apparent. According to the SNIS 2019, Brazil has a loss rate of 39.2%. This lost volume impacts the companies financially and the hydraulic conditions within the supply system itself, as it influences the pressures within the pipes, which is an important aspect for the water to reach the most distant points of the system. In order to reduce the levels of losses there are several methodologies, analysis tools and control equipment available, such as: the implementation of monitoring and control equipment, and hydraulic modeling. Palmeiras dos Índios presents a high rate of losses and one of the indications for this lost volume is the breakage of networks due to high pressure in the system. The tools mentioned above should help to reduce the rate of losses and control pressure if used for the supply system of the city of Palmeira dos Índios, in Alagoas, therefore, in this study we verify, through the Epanet software, the implementation of Measurement and Control Districts (MCDs), pressure reducing valves (PRV) and the implementation of new pipes.
