Survival Analysis in Water Supply Networks

The problem of aging water supply networks affects almost all cities in developed countries. Different strategies can be used to apply the high investments required by network renewal in the best possible manner. Among them, one of the most important is the identification of influential factors in pipe failure risk and the subsequent possibility of forecasting the risk affecting different pipes. This requires the existence of adequate historical databases, which have not always existed, and the use of statistical survival models to identify these influential factors and to evaluate the pipes failure risk.
