25、 2017 All rights reserved ISO 24516-3:2017(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each membe
26、r body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Elec
27、trotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types o
28、f ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held
29、 responsible for identifying any or all such patent rights.

33、er and to some degree. It focuses on the details of managing the physical assets at the operational level rather than the organizational (corporate management, structural or process) level.Wastewater utilities are reliant on their assets to deliver their services to the resident populations in their
34、 jurisdictions. The assets (underground pipes, retention and detention tanks, treatment plants, etc.) collectively form the physical infrastructure of the wastewater utilities and are the consequence of the accumulated capital investments and operational expenditures on maintenance and rehabilitatio
35、n over many years. In many of these utilities, the replacement value of these past investments will amount to many millions (even billions) of US dollars depending on the size of the community served. The infrastructure represents therefore a major societal investment in essential services contribut
36、ing to public health and the protection of the environment.In many countries, these assets have been identified as critical infrastructure, and programmes are in place to ensure their protection or their sustainability. Like many other organizations having assets, wastewater utilities undertake prog
37、rammes of activities to manage the assets to ensure they continue to meet the needs of the community. These management activities can be at the strategic, tactical or operational level. The activities can be part of a formal management system, the result of specific legislative requirements, or simp
38、ly the result of due diligence by the service operators and managers.This document can serve as a supporting document for utilities operating an asset management system regardless of whether the utilities make use of any management system standard (e.g. ISO 55001).In many countries, there is a recog
39、nized sustainability problem, sometimes referred to as the infrastructure gap, which recognizes that for various reasons, the infrastructure has not been maintained over the years on a truly sustainable basis, i.e. funding of rehabilitation programmes has been postponed, with a focus instead on shor
40、t-term repairs or an allowed decrease in the level of service provided.The condition of wastewater infrastructure greatly influences the adequacy of the wastewater service from aspects of quantity, quality, safety, reliability, environmental impact, degree of treatment and economic efficiency. Syste
41、m condition-based rehabilitation approaches serve to meet these requirements with a focus on a holistic approach of condition-based, risk-oriented maintenance.As the installation and development of wastewater assets mature, the optimization of networks will become necessary in many places in order t
42、o respond to changing societal and economic conditions. Consequently, networks are subject not only to ageing as well as wear and tear but also to adaptation processes resulting from growth, new legislative requirements, or changing user service level expectations. This requires wastewater utilities
43、 not only to focus on maintenance and rehabilitation but also to keep future requirements and developments in mind. Rehabilitation will thus become essential in management of assets, with ever more stringent requirements on the design and execution of rehabilitation (partial replacement of specific
44、sections of the entire network is also considered as rehabilitation).In recent years, much effort has been applied to the whole issue of management of assets on two levels: What are the principles and structure of an asset management system? What are the good practices that can be implemented on a t
45、echnical level to assess the condition of the assets and help decide when asset interventions (repair, renovation or replacement) take place?This document describes the information required and how to collect and process reliable inventory, condition, operational and environment data about wastewate
46、r systems. Data on wastewater infrastructure notably include data on failure. These data serve mainly as a basis for systematic maintenance and can also contribute data needed for benchmarking.vi ISO 2017 All rights reservedBS ISO 245163:2017ISO 24516-3:2017(E)IntroductionThis document is written wi
