“…Gilchrist and Allouche (2005) used data from road works studies to estimate the cost of delayed travel time and traffic jams. Similarly, Werey, Janel, and Weber (2003) provided profit/loss ratios usable to activity disruption due to water delivery cut for each specific activity sector or flooding. Regarding protection costs, considering the costs for protection from flooding due to sewer network malfunctions could be an alternative.…”

Sewer asset management gained momentum and importance in recent years due to economic considerations, since infrastructure maintenance and rehabilitation directly represent major investments. Because physical urban water infrastructure has life expectancies of up to 100 years or more, contemporary urban drainage systems are strongly influenced by historical decisions and implementations. The current decisions taken in sewer asset management will, therefore, have a long-lasting impact on the functionality and quality of future services provided by these networks. These decisions can be supported by different approaches ranging from various inspection techniques, deterioration models to assess the probability of failure or the technical service life, to sophisticated decision support systems crossing boundaries to other urban infrastructure. This paper presents the state of the art in sewer asset management in its manifold facets spanning a wide field of research and highlights existing research gaps while giving an outlook on future developments and research areas.
