Relação do número de habitantes e a ausência de esgoto sanitário nos municípios do centro-oeste brasileiro

Abstract

The provision of services linked to basic sanitation is essential to guarantee the quality of life of the population. The lack of collection and treatment of sewage combined with the lack of investments in this sector, directly affects the area of health, education and the environment. The execution of these services demands an infrastructure, which most of the municipalities do not have, especially the small ones. Thus, this study approaches the Brazilian situation in terms of sanitary sewage, analyzes and identifies if there is any relationship between the number of inhabitants and the absence of sewage collection in the 467 municipalities of the Brazilian Midwest. The study was carried out in a quantitative approach where the variables passed through statistical tests, and the hypotheses for confirmation were formulated, with data extracted from the Sewage Atlas in the calendar year of 2013. The explanatory variable was the number of inhabitants of the municipality of the Center -Oeste (NH) eavariable explained was the percentage of failure to collect sanitary sewage (% AES), where it showed a negative and significant relation of 1%, confirming the hypothesis of the study, and corroborating previous studies; the constant presented a positive and significant relationship at 1% with the dependent variable. By analyzing the data, it is suggested that in future research, it would be very important to study the investments made in the sanitary sewage bill and the number of inhabitants in the municipalities of the Center-West of Brazil.
