19、ordISO (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 member body interested in a subject for which a technic

20、al 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 Electrotechnical Commission (IEC) on all matters of el

21、ectrotechnical 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 of ISO documents should be noted. This document was

22、 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 responsible for identifying any or all such paten

ISO 2016 All rights reserved vBS ISO 24516-1:2016ISO 24516-1:2016(E)IntroductionThis document is written within the overall concept of management of assets which is an activity all organizations undertake in some manner and to some degree. It focuses on the details of managing the ph

27、ysical assets at the operational level rather than the organizational (corporate management, structural or process) level.Drinking water utilities are reliant on their assets to deliver their services to the resident populations in their jurisdictions. The assets (underground pipes, reservoirs, stor

28、age tanks, treatment plants, etc.) collectively form the physical infrastructure of the drinking water utilities and are the consequence of the accumulated capital investments and operational expenditures on maintenance and rehabilitation over many years. In many of these utilities, the replacement

29、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 contributing to public health and the protection of the environment.In m

30、any countries, these assets have been identified as critical infrastructures, and programmes are in place to assure their protection or their sustainability. Like many other organizations having assets, drinking water utilities undertake programmes of activities to manage the assets to ensure they c

31、ontinue to meet the needs of the community for reliable delivery of drinking water. 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 simply the result of d

32、ue 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 recognized sustainabili

33、ty 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 and implementation of rehabilitation programmes have been postponed, with a focus instead on sh

34、ort-term repairs or an allowed decrease in the level of service provided.The condition of water infrastructures greatly influences the adequacy of the water service from aspects of quality, quantity, pressure, safety, reliability, environmental impact, degree of treatment and economic efficiency. Sy

35、stem 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 water assets mature, the optimization of networks will become necessary in many places in order to

36、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 customer service level expectations. This requires drinking water uti

37、lities 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 spe

38、cific 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

39、on a technical 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 context data about drinkin

40、g water systems. Condition data for the underground water 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 2016 All rights reservedBS ISO 24516-1:2016ISO 24516-1:2016(E)Reliable f

41、ailure statistics and the database description of the condition are of particular significance for establishing investigation, maintenance and rehabilitation priorities.This document also provides guidance on how to define a strategy on management of assets with regard to the overall performance exp

42、ected by the drinking water utility and other stakeholders. It includes several aspects of the operation and maintenance, including asset condition assessment and investment strategies (new assets and rehabilitation).The approaches offered in this document are intended to be universally applicable,

43、regardless of the structure of a given water system.The usual and expected goal of the effective management of assets is to provide an appropriate service life while fulfilling given requirements in a cost-effective manner.This document is intended to provide guidance on the assets typically owned o

44、r operated by drinking water utilities (networked drinking water systems) that are expected to meet customer needs and expectations over longer (multi-generational) periods.Additional information on objectives of management of assets is provided in Annex A. Information on the assessment of typical s

45、ervice life and age-based failure rates of pipes is shown in Annex B and risk-based prioritization of pipe rehabilitation in Annex C.

46、water distribution networks1 ScopeThis document specifies guidelines for technical aspects, tools and good practices for the management of assets of drinking water networks to maintain value from existing assets.This document does not apply to the management of assets of waterworks (including catchm

47、ent and treatment, pumping and storage in the network), which are also physically part of the drinking water system and can influence the management of assets of the pipe network.NOTE 1 The drinking water network is taken to include both pressurized and non-pressurized (i.e. containing free surface

48、flow) conduits and accessories such as valves and control or metering equipment.NOTE 2 The management of assets of drinking water pumping stations and storage in the network will be included in another part of the ISO 24516 series.This document focuses on the assets typically owned or operated by dr

49、inking water utilities (networked drinking water systems) that are expected to meet customer needs and expectations over longer (multi-generational) periods.This document includes examples for good practice approaches on the strategic, tactical and operational levels.This document is applicable to all types and sizes of organization and/or utilities operating drinking water systems, and all different roles/functions for the management of assets within a utility (e.g. asset owner/responsible body, asset manager/operator, service provider/operator).NO
