Water quality failures in distribution networks - risk analysis using fuzzy logic and evidential reasoning

摘要

This paper proposes a systematic approach for using quantitative-qualitative data to evaluate the risk of distribution network water quality failures. The methodology is based on five failure mechanisms: contaminant intrusion, leaching and corrosion, biofilm formation and microbial regrowth, permeation, and water treatment breakthrough (including disinfection byproducts formation). The proposed methodology is demonstrated using a simplified example for water quality failures in a distribution network.
