Abstract: In this paper the authors describe a tool (the Repair/Replace Tool; R/R tool) they have developed in order to help water utilities make the decision whether to replace or repair a pipe. The tool is based on a comparison between the cost of replacing a pipe with the cost of just repairing it, i.e., potentially facing more breaks and repair costs in the future until the pipe is finally replaced. The tool includes the use of innovative analytical elements such as an advanced failure forecasting statistical model and a pipe grouping algorithm. The tool is to be placed within an overall Asset Management program that takes into account different perspectives (long term planning vs. short term planning vs. immediate response to a break; system level vs. pipe level). A software has been developed.
