ELABORAÇÃO DE PLANO DE SEGURANÇA DA ÁGUA (PSA) PARA ETA DE MARÉS - CAGEPA EM JOÃO PESSOA/PB

Abstract

As discussions about our most precious natural asset – water – increase, the concern with the quality and safety of this resource offered to consumers becomes increasingly evident. Thus, the Water Safety Plan (WSP), tool developed by the World Health Organization (WHO) is highlighted, which allows the assessment and preventive management of health risks associated with water supply network, from the source to the consumer's tap. A relatively recent alternative that, in Brazil, gained strength with the update of Ordinance GM/MS no 888/2021 of the Ministry of Health, which introduces the possibility for the public health authority to demand from those responsible for water collective supply systems and solutions, the elaboration and implementation of the WSP. The present study aims to describe the construction and implementation of a WSP in the Water Treatment Plant of the Marés system, from CAGEPA, in João Pessoa, Paraíba. In summary, the development of the WSP was divided into three stages. The first was intended to carry out a risk assessment, identifying all hazardous events and process hazards. The second stage comprised the creation of action plans and the delimitation of critical limits for the treatment phases. Finally, in the third stage, the Emergency and Contingency Plan was created. The development of this work was essential for the practical understanding of the Water Treatment Plant, and the system in general, recognizing its potential, as well as its limitations and deficiencies.
