This paper proposes a methodology for managing complex sewerage networks based on the concomitant use of two performance evaluation methods, namely, failure modes, effects, and criticality analysis (FMECA) analytical hierarchy process (AHP). The FMECA is used to determine risks structural failures making it possible establish these failures. AHP check relationship consistency between indicators...
