ABSTRACT
The drinking water network in the city of Mendoza, Argentina, is, for a great proportion of pipes, more than 40 years old. The network is confronted with a significant number of repairs and leakage is very important. The operator uses a methodology issued from experience in France, which consists of sampling representative lengths of pipes and analysing them for corrosion. Environmental influences are also taken into account for the calculation of corrosion speed. The objective is to obtain a program of replacement based upon the estimation of the remaining lifespan of each pipe in the network.
