Assessing the condition of water pipes is a complex task, partly due to scarcity of complete maintenance records and field observations. This makes it harder to identify the factors determining pipe condition and their probabilistic relationships with the deterioration process. A challenge facing water utilities is to find an effective and reliable tool for assessing their pipelines and taking prompt decisions regarding repair and maintenance to extend the service life and keep them safe from sudden failures. This paper presents research on a new fuzzy-based methodology for modelling water pipe condition prediction. It proposes a hierarchical fuzzy rule-based model that uses a simplified and effective method for supporting the elicitation of the fuzzy rules and adapting uncertainty propagation that can be intuitively understood by human experts. The results of applying the model to the water pipes domain shows the plausibility of extending the approach to other knowledge domains based on human expertise
