Water and sewer networks and levees must be managed in a way that guarantees their performance over time. Maintaining their service in the long-term involves huge public health and safety, social, economic and environmental stakes. This calls for integrated asset management rules and strategies to mitigate the consequences of ageing and possible obsolescence integrating life cycle approaches. The aim of this article is to present the various approaches developed by Irstea with its partners over several years relating to these three types of infrastructure. It also proposes elements of comparison and synthesis between these approaches with respect to their objectives and implementation.
