Aplicação do índice de acessibilidade de água: estudo de caso Fortaleza, Ceará

Abstract

Water security has evolved and encompassed in its studies social factors in addition to the physical availability of water. The diversity of these factors and the assessment of access to water becomes inevitable for the understanding of the water resources system. Many indexes have been used to analyze such aspects. Therefore, this article proposes the application of the accessibility index as a subsidy tool for the analysis of urban water security. The index was applied to the city of Fortaleza and related the water bill to the per capita monthly income. It was found that 18.5% of the neighborhoods have a water bill with a significant portion of monthly income and that 11.7% are low-income neighborhoods with a new sewerage network, meaning an increase in the index in these regions. Enabling the price of water within the recommended 5% is a challenge since it is necessary to cover costs related to water and infrastructure services, as well as environmental costs.
