An objective of infrastructure asset management of drinking water network is to minimize risks (service outage, or disruption of vehicular traffic...). However there are several methods to assess their frequency. This paper first discusses the different models used in predicting the structural deterioration, because it is a compulsory preliminary step to calculate risk. Risk models for service outage are then discussed.
