Given the proportions of the high consumption of water resources and disorderly urban occupation, it is essential to implement and control a water distribution system suitable for human consumption. For effective management of this resource in the network, the analysis of the physical-chemical parameters of the water allows its characterization and points out possible problems in the network, like clandestine connections, which can impact the quality of the water supplied to the population, in addition to increasing the loss rate of the supply systems. Therefore, the monitoring of these parameters in the long term, with the reception of continuous data, allows the rapid detection of anomalies in the network and, therefore, becomes an important tool in quality assurance. The parameters defined by the Potability Ordinance of the Ministry of Health, as the most representative, for assessing the quality of water in the distribution network are pH, Turbidity, Color, Residual Chlorine, Fluoride, Total Coliforms and E. Coli. The present work aims to detail the implementation, validation and operation of the online water quality monitoring system, installed from a branch in the water supply pipeline at water supply sub-ductor of Catonho, one of the five water supply sub-ductor of distribution block 2 water managed by Iguá Saneamento, responsible for supplying the Barra da Tijuca, Jacarepaguá and adjacent neighborhoods in the city of Rio de Janeiro. For this, previous studies were evaluated, as well as the installation and operation steps according to the manufacturers' manual and validation by comparing data from equipment in network monitoring and bench analysis. The equipment installed in the distribution network has sensors for measuring the parameters of apparent color, free residual chlorine, fluoride, pH and turbidity, sent to the storage server via transmission over a cellular network. Data were evaluated by statistical methods and validated by comparison with bench analyses. However, the calibration procedures need to be improved to improve the comparative correlation of the data and their reliability, mainly in the fluoride, color and turbidity instruments. Even so, real-time monitoring allowed for faster decision-making by the company responsible for maintaining the distribution network.
