Estudo do sistema de abastecimento de água de Pitangueiras - PR: um proposta de PSA

Abstract

This study presents the development of a proposal for a Water Safety Plan (WSP) for the municipality of Pitangueiras, Paraná, with the aim of strengthening the preventive management of the public water supply system and ensuring the safety of the water provided to the population. The methodology followed the guidelines of Ordinance GM/MS No. 888/2021 and involved data collection provided by the local water supply service (SAAE), technical visits to catchment and distribution points, document analysis, application of the principles established by current legislation, and construction of a risk matrix for the three wells that make up the system. The study included the characterization of the catchment structures, evaluation of operational procedures, analysis of raw and treated water quality results, and identification of hazards and hazardous events associated with the functioning of the water supply system. The physicochemical and microbiological analyses performed by SAAE remained within the legal potability limits, indicating compliance of the monitored parameters throughout the evaluation period. Nevertheless, the application of the WSP methodology made it possible to identify relevant risks related to structural integrity, surrounding environmental conditions, potential introduction of contaminants, and operational factors, highlighting the need for systematic maintenance of structures, adequate control of chemical products, and continuous monitoring of equipment and facilities. Although no nonconformities capable of compromising the public water supply system were observed, the study emphasizes that prevention is a central element of water safety, and that maintaining consolidated routines of monitoring, inspection, and response to unexpected events is essential. In conclusion, this work provides the municipality with a practical tool to organize and strengthen water safety management, contributing to the reduction of vulnerabilities, improvement of operational efficiency, and support for decision-making, especially in contexts where technical and structural resources are limited.
