Análise de perdas de distribuição de água em diferentes localidades de Goiás.

Abstract

This research presents an analysis of water distribution losses in different locations in Goiás, focusing on comparing operational methods in the water distribution system among five municipalities in Goiás: Águas Lindas de Goiás, Anápolis, Aparecida de Goiânia, Goiânia, and Rio Verde. Data available in the SNIS (National Health System) for 2023 were used. The specific objectives were to analyze and compare ten operational water indicators: total service rate, water billing rate, billing loss rate, distribution loss rate, gross linear loss rate, and loss rate per connection. A quantitative case study methodology was used, and the results reveal significant differences among the municipalities. In terms of billing loss rates, Aparecida de Goiânia, Goiânia, and Rio Verde presented losses below 25%. In terms of water loss in distribution, Goiânia and Rio Verde stood out with values below 25%. In terms of gross linear loss, Aparecida de Goiânia, Goiânia, and Rio Verde achieved values below 10 m³/day/km. Goiânia stood out with a strong performance across all indicators, as the state capital receives the most investment. Águas Lindas de Goiás had the worst result among municipalities, with a revenue loss index of 41.01%. In terms of water loss in distribution, the municipality had a loss value of 40.82%, and a gross linear loss index of 66.19 m³/day/km. Thus, this research enabled the analysis of possible causes for poor results in reducing losses.
