Caracterização do consumo de água doméstico na zona urbana de Alegrete/RS

Abstract

The present study aims to characterize the domestic water consumption per capita in the city of Alegrete / RS, by district, using residence consumption data, provided by local utility services – Companhia Riograndense de Saneamento (CORSAN) and sanitation rates obtained in project ISA Alegrete / RS . Based on the water consumption data and the average population by district, determined the average water consumption of each municipal district for characterization of consumption, comparing them with daily consumption indicated by literature and sanitation companies. The results show that the average water consumption per capita by district ranged from 74 to 190 litres per person per day, showing that there is variability between the districts, in view of the many factors that influence water consumption standard of a population. In terms of average consumption data per capita water indicated by the literature, National Sanitation Information System (SNIS) and sanitation companies, verifies that such data do not reflect the local reality. After, it was performed the linear correlation analysis between the average consumption data per capita water and socioeconomic indices (ISE), water treatment (IAA), environmental health (ISA). In the linear correlation analysis between the indices, there was a variation from 0.118 to 0.348, not being able to affirm the existence of strong correlation.
