Plano de segurança da água do município de Janiópolis-PR: etapas iniciais de preparação

Abstract

Providing clean drinking water to a community should be the foremost sanitary and social action in any sanitation program. The Water Safety Plan (PSA) serves as a tool to identify potential deficiencies in the water supply system (SSA), structuring and organizing the system to minimize the likelihood of incidents. Additionally, the WSP establishes contingency plans to respond to system failures or unforeseen events. Consequently, this study aimed to develop the initial stages of the Water Safety Plan for the municipality of Janiópolis in Paraná, Brazil. The study followed the WSP stages in accordance with the guidelines provided by the Ministry of Health. These initial stages encompassed system evaluation, including a description of the SSA, construction, and validation of flow diagrams, identification and analysis of potential hazards, risk characterization, and the establishment of critical control measures. Based on the data collected, a brief description of the urban SSA was provided, followed by the development of the initial stages of the PSA for seven rural communities within the municipality. Hazardous events such as source contamination, reservoir contamination, pipeline blockages, and leaks were identified. After assessing the identified risks and potential risks within the SAC, four non-tolerable hazardous events, nine non-acceptable events, and three acceptable risks were identified. Consequently, measures will need to be taken according to their nature and potential to control and/or prevent these events from occurring in future incidents.
