Análise de conformidade de indicadores sentinelas da qualidade da água de abastecimento de Campina Grande-PB.

Abstract

The water supply system is a set of civil works, materials and equipment intended for the production and distribution of piped drinking water to populations. The quality of water in a water supply system may change during its journey in the distribution network, which demonstrates the vulnerability of wastewater. The search for methodologies that allow the early identification of possible health risks associated with the degradation of water quality for human consumption becomes one of the challenges in action planning for surveillance of water quality. The sentinel indicators are instruments that act early, effective and economical in identifying those changes that can cause waterborne diseases, can be prevented and control through sanitation measures. This work has as main objective to analyze, on a consolidated basis, from the risk assessment, the water supply system of Campina Grande. Thus, the study used the technique of FMEA risk assessment that generated results as the definition of system risks, their classification regarding the importance, as well as identify which points in the system had a greater violation of standards established in the Ordinance MS/2914. We also used the technique of fault tree which allows clear visualization through imaging, of the possible causes of such risks becoming a facilitator in managing the quality control of water. The risk weighting for classification was more effective when used only CRL and turbidity, which proved the importance of sentinel indicators for monitoring water quality.
