Asset Management of Urban Drainage Systems: If anything exciting happens, we've done it wrong!
Asset management issues are and will always be key concerns for many stakeholders in the water sector. Despite this, there is still a lack of awareness and clear guidance on the topic. There has been some focus on the management of drainage pipes, but more effort needs to be dedicated to examining the various regulations, practices, and research within this discipline. It's paramount to consider the long-term management of urban drainage assets, given the role they play in ensuring the wellbeing of our communities.
Asset Management of Urban Drainage Systems is the first comprehensive handbook that deals with the asset management of infrastructure dedicated to both sewage and stormwater, including blue-green infrastructure. It gives an insight into the theoretical background of asset management itself and showcases regulations and legislation influencing it. The methods used to investigate the condition of assets, and how they can be modelled and represented while accounting for the associated limitations, are also presented. The book describes how the discipline can move from a purely condition-based approach to a service-based one using risk-management strategies, seen in the broader context of decision-making. Data management and techniques for the rehabilitation of urban drainage assets are also explored.
From technicians who want to know more about the tools and methods, to researchers and students who want a broad overview, to professionals who are tasked with developing short, medium, and long-term asset management strategies, this book provides important content for a wide audience.

Abstract
Condition assessment often serves as the primary, and at times, the exclusive factor driving the prioritization of rehabilitation requirements. While this methodology signifies a substantial departure from a ‘run-to-failure’ strategy, it does possess inherent limitations. Notably, it has been demonstrated to exhibit constrained efficiency, potentially resulting in the refurbishment of assets with minimal risks or inconsequential impacts. An evolved and more sophisticated perspective on asset management involves a comprehensive evaluation of the functions delivered by infrastructure elements, whether they pertain to drainage pipes or other stormwater control measures. By harmonizing the state of assets with the contextual stakes and vulnerabilities within the specific territory or region under the purview of the utility manager responsible for the upkeep of the drainage network, a more precise targeting of rehabilitation necessities can be achieved. This precision, in turn, culminates in a notable enhancement of the system's overall performance. This holistic approach, commonly referred to as a risk-based strategy, furnishes an inclusive framework for optimizing location strategies. This optimization hinges on the prioritization of rehabilitation requisites through a meticulous multi-criteria analysis. This chapter delves into the foundational functionalities inherent in urban drainage systems, coupled with their associated services. Subsequently, the succeeding section elucidates the shift from a condition-centred methodology to a performance-centric approach. A series of illustrative case studies follow, providing real-world context to the concepts discussed.
