Prioritizing Water Mains for Inspection and Maintenance Considering System Reliability and Risk

This paper presents a method for prioritizing water mains for inspection and maintenance with consideration of municipalities with a lack of data for failure probability assessment. The method employs reliability and risk of a pipeline system to determine the maintenance schedule for each pipe component in the system. A simple Weibull function–based failure prediction model is developed for the pipe components based on a stochastic analysis...
