This chapter covers the legal framework and technical regulations that must or should be observed for the strategic asset management (AM) of urban drainage systems over the entire life cycle (planning, construction, maintenance, and dismantling). A distinction is made between rules and regulations that deal with network management in general (strategic level) and rules and regulations that address the management of individual network components and/or certain activities (e.g., CCTV-inspection and condition assessment of reaches or stormwater basins). These activities are subsumed under ‘operative level’.
It should be noted that both the legal framework and the applicable technical regulations vary widely from region to region. In some cases, different regulations apply even in different provinces or federal states of a country. Against this background, only case studies can (such as regulations that apply to Germany, France, Colombia or Canada) and will be presented in this chapter.
It is thus made clear that AM in the sense of ISO 55000 to 55002 (AM) enables a structured approach to a multi-layered field of tasks. In this way, goals and conflicting goals can be identified and prioritized at various levels and, in conjunction with the continuous improvement process in accordance with ISO 9000 and 9001 (Quality Management Systems), efficient ways can be found to achieve these goals.
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.
