Résumé:
Risk is something that has permeated humanity since its inception. Through
their perception, it is possible to conjecture undesirable future scenarios and,
this time, enable their elimination or mitigation since their materialization is likely
to bring harm to the organization, to human beings and even to the
environment. Therefore, the application of risk analysis methodologies helps
companies to prevent or reduce the impact caused by any mechanisms that
affect the quality of the service provided and the operability of the system.
Composing the list of services, water supply systems (SAA) are included, which
are complex in their operation and, like any other activity, are subject to failures.
The objective of this research was to list the potential failure modes inserted in
each stage of the SAA in the municipality of BananeirasPB.
For this purpose,
the Failure Mode and Effects Analysis (FMEA) methodology was used,
considering the steps of Capture, Adduction, Treatment, Elevation of Treated
Water, Reservation and Distribution of the system. Eleven professionals linked
to the area of water resources and sanitation were interviewed, from operational
technicians who work in the SAA of Bananeiras, civil engineers to university
professors who, through their technicaloperational
knowledge, could quantify
the causes of failures and their respective degrees of Severity, Occurrence and
Detection and, through the products of the three indexes, find the degree of risk
(NPR) for each step of the system. With the results obtained, it was possible to
rank which events are more likely to happen, as well as their magnitude and
chance of interrupting the service provided to users. Through weighting, the
distribution stage was the one with the highest NPR. It is necessary to insert
prevention and mitigation measures in order to mitigate the possible flaws
inherent to the system, given that some are already taking place.
