This document was prepared by Technical Committee ISO/TC 224, Service activities relating to drinking water supply systems and wastewater systems Quality criteria of the service and performance indicators. ISO 2017 All rights reserved v ISO/TS 24520:2017(E) Introduction Water is the s

20、ource of life, without which humans, as well as other species, cannot survive. In many countries, there is a lack of knowledge regarding crisis management of drinking water and wastewater services. Impairment of the drinking water service would change the quality of life of the affected population i

21、n the immediate period while in the medium-term it could affect their ability to survive. Therefore, the continuous and orderly supply of clean water is of paramount importance for the population. The collection, treatment and safe disposal of sanitary wastewater are also important if illness and/or

22、 inundation are to be prevented and the environment protected. This document describes good practice in the establishment of technical crisis management systems drawn from experience contributed by relevant national authorities. The approach of a water utility when preparing for any crisis should en

23、compass all pertinent aspects of water supply and the collection, treatment and safe disposal of wastewater. The water utility needs to cooperate with all relevant authorities concerned with the crisis. Effective crisis management should ensure that the actions taken before, during and after the cri

24、sis consider the natural environment as well as the impact on the health and wellbeing of the population. Effective communication with the public is necessary to mitigate or prevent panic and to establish trust in the water utility by disclosing important information appropriately in the area affect

25、ed by a crisis, in neighbouring areas or to any other stakeholders. This document can be used as a toolkit by water utilities where they wish to review their current capability to prepare for, respond to and recover from a crisis in an effective and efficient manner. It is not intended as a complete

26、 guide to crisis management. Water utilities can consult ISO 24518 if they need further guidance.vi ISO 2017 All rights reserved Service activities relating to drinking water supply systems and wastewater systems Crisis management Good practice for technical aspects 1 Scope This document provides gu

42、 this context extend from within an organization to the global system. Note 2 to entry: For the application of this document, environment is considered as a specific stakeholder (3.38). The interests of this specific stakeholder can be represented by relevant authorities (3.33), by the communities o

43、r by other groups, such as non-governmental organizations (NGOs). 3.17 hazard source of potential harm Note 1 to entry: Harm in the context of a water utility can include injury to stakeholders; compromising of public health; degradation of the environment; a deterioration in service quality; reputa

44、tional and/or financial damage; and consequential sanctioning by the relevant authorities. Note 2 to entry: Capacity for harm can also arise from compromised service provision. In this context a hazard can be considered to be a biological, chemical, physical or radiological agent in, or condition of

45、, water with the potential to cause harm to public health or the environment (3.16). This perspective is based on the definition of “hazard” in the WHO Water Safety Plan Manual expanded to include “condition”, which includes quantity (i.e. a shortage or an excess), hence making it applicable also to

46、 wastewater (3.40) service (3.37). Note 3 to entry: Other sources of potential harm exist within the water utilitys organizational context. These hazards can be internal or external to the organization (3.26). Internal hazards could be tangible (e.g. a toxic chemical store; potential energy stored b

47、ehind a dam perched on a hillside above a town; a chamber potentially containing a hazardous atmosphere) or intangible (e.g. poorly documented procedures; inadequate training; an inappropriate organizational culture). External hazards could be tangible (e.g. earthquake; flooding; forest fire) or int

48、angible (e.g. social unrest; terrorism, cyber threat, corruption; financial instability). 3.18 hazardous event event that introduces one or more hazards (3.17) to, or fails to remove them from, the drinking water (3.13) system or the wastewater (3.40) system Note 1 to entry: The equivalent French wo

49、rd for the English expression “hazardous event” is “evenement dangereux”. However, the English word “danger” has been removed from this document as it is synonymous with “hazard”. Both “hazard” and “danger” convey the concept of a potential risk (3.36). When it comes to describing hazard, the English terminology remains consistent, e.g. “fire hazard”, but the equivalent French expression “Il y a risque dincendie” migrates to using the equivalent of the English term “risk”. The difficulty is that the meanings of “hazard” and “risk” a
