Evolução dos indicadores de abastecimento de água potável e esgotamento sanitário no Rio Grande do Norte no período de 2007 a 2019

Abstract

The National Basic Sanitation Policy (Act nº. 11,445/2007) and the new Legal Framework for Basic Sanitation (Act nº. 14,026/2020) determine that universal access is a fundamental principle of the provision of public sanitation services. To achieve this objective, the drinking water supply and sanitary sewage services aim, for 2033, at a coverage rate of 99% and 90%, respectively. Historically, the development of the water supply sector in Rio Grande do Norte has surpassed the average of the Northeast region however, in the sanitary sewage sector the situation is the opposite. Therefore, this work proposes to analyze the evolution of the indicators of drinking water supply and sewage in Rio Grande do Norte in the period from 2007 (beginning of act nº 11.445/2007) to 2019, the last reference year available when it started this research. The methodology of this analysis used mainly secondary data extracted from the National Sanitation Information System (SNIS) database. Operational indicators for water, operational sewage, the quality of services provided, and financial indicators were analyzed. It is concluded that in the analyzed period, the selected indicators evolved satisfactorily, but the sanitary sewage sector needs to be prioritized, due to the results of the total sewage service rate is dwindling.
