• Abstract:

  The present work aims to show the application of a system of performance indicators to evaluate the quality of drinking water distributed by Water Supply Systems (SAA) and its functionality in relation to the technical regulation of the basic sanitation service provider. Four parameters were chosen to systematically evaluate water quality for the SAA, they are: Turbidity, Free Residual Chlorine, Total Coliforms and Escherichia coli. Indicators of non-conformity of samples analyzed for the selected parameters were established and aim to verify the standards established by Annex XX of Consolidation Ordinance, number: 5 of the Ministry of Health, and an indicator that aims to summarize the information of all others in a single, called the Drinking Water Quality Index (IQAP). The measurement of indicators was carried out at the treatment outlet (st) and in the distribution network, allowing the assessment of the quality of drinking water in both positions independently, providing better identification and location of problems. In terms of the indicator's spatial coverage, the calculation was carried out first in its smallest dimensions, then expanded through the sum of data or averages for larger dimensions. As a result, it was possible to investigate the deficiencies and performance of the SAA, helping the agency in decision-making and action through regulation by exposure, providing interchangeability and dynamism of the Public Entities responsible for guaranteeing the quality of drinking water supplied by the SAA.
