ANÁLISE DAS PERDAS NOS SISTEMAS DE ABASTECIMENTO DE ÁGUA NOS MUNICÍPIOS DO MATO GROSSO DO SUL

Abstract

The analysis of losses in water supply systems is a topic that has become increasingly relevant and necessary, with a highlight to the water resources management aspects, in view of the sustainability and availability of water around the world. In Brazil, the waste of water in distribution systems is a serious but little studied problem at the state and municipal level. In this context, the present study aimed to analyze the indicators of losses in the water supply systems in Mato Grosso do Sul municipalities between 2011 and 2020, using the four most representative indicators from the database of the National System of Information on Sanitation (SNIS). The reference numbers of the four indicators in all municipalities in the state were evaluated by using data collected from service providers and made available by the Ministry of Cities. Results showed that the municipalities of Novo Horizonte do Sul and Japorã had an excellent performance in reducing water losses in their supply systems, indicating water resources efficient and conscious management. On the other hand, the municipalities of Corumbá and Ladário had above-average water loss rates, indicating problems in the systems management and operation, such as network leaks and illegal connections. In this sense, it is important that the municipalities of Mato Grosso do Sul invest in loss control programs and constantly seek to improve the efficiency of their systems in operation.
