Introduction This guideline has been developed by Working Group 15 “Security of drinking water” of CEN/TC 164 “Water supply”. This guideline describes the fundamentals of crisis management, including relevant recommendations for drinking water suppliers, and offers examples drawn from disaster and crisis management organisations within the relevant contributing national authorities. Drinking water suppliers should have at their disposal appropriate equipment, sufficiently qualified personnel and reliable quality assurance measures. They should be organised in such a way as to ensure their services are provided in a safe, reliable, environmentally friendly and economical manner under normal supply conditions. The existence of an effective and efficient risk management system will support any organisation's crisis management process. Guidelines on risk management regarding the security of drinking water supply exist in a separate document (prEN 15975-2) in development. Extremely rarely however, certain situations occur that drinking water suppliers may not be able to control without significant third-party assistance and the involvement of the relevant authorities. These situations are difficult to forecast and, therefore, impossible to make detailed provisions for. They are characterised by an absence of, or the presence of ambiguous, information and high risk with severe potential consequences. The situation's degree of complexity due to the involvement and interaction of different players and its high degree of intrinsic dynamics make it difficult to control. Key personnel involved may suffer from a high degree of pressure regarding decision-making, time and justification requirements while having at their disposal only a limited number of resources. Internal and external communications may work unsatisfactorily or not at all. Decisions need to take appropriate account of the specific circumstances of the crisis and the key objectives for restoration of normal water supply services. These guidelines have been developed by CEN to support that aim. The objectives of these guidelines are to enable the drinking water supplier to take action in the event of a crisis in order to ensure the continued supply of water to the greatest possible extent and to restore normal operating conditions as quickly as possible. The management tools required to achieve these objectives are explained in this standard. Basic steps of the workflow described in this standard (see Figure 3) may also be used during normal operations that have the potential to become a crisis. Across Europe there are many different ways to organise drinking water supply. The responsibility for crisis management may differ depending on legislation and organisational structures. In this document the term "drinking water supplier" is used to reflect all the different organisational structures. Member States may chose to specify these structures in more detail. National legislation may impose definitions that differ from the ones defined in this standard. In this case the necessary adaptations should be made in the application of this standard.
NOTE Such capability also includes the organisation of preparatory and follow-up structural and process activities. 2.3 disaster situation where widespread human, material, economic or environmental losses have occurred that exceeded the ability of the affected organisation, community or society to cope using its own resources 2.4 emergency sudden, urgent, usually unexpected incident or circumstance that is highly likely to or will cause grave damage to persons or assets or considerably impair the supply of drinking water and that requires immediate action frequently involving the relevant authorities (e.g. police, public health officials, and local authorities) 2.5 incident deviation from normal operating conditions NOTE An incident is characterised by its cause, the extent and the consequences of the deviation. 2.6 hazard potential source of biological, chemical, physical or radiological impairment of the water supply system NOTE Each organisation should determine the maximum credible hazard (the ‘Design Basis Hazard’) that the organisation plans to have a capability to respond to. By definition the organisation is therefore tolerant that its crisis management response to events or circumstances exceeding the Design Basis Hazard may be inadequate. 2.7 normal operation general term describing all water supply-related operating conditions and processes including failures that can be controlled by the normal means of operation and/or organisation structures selected by the water supplier 2.8 risk (of hazard) combination of the likelihood of a hazardous event and the impact of that event on the integrity of the drinking water supply system and on related stakeholders SIST EN 15975-1:2011

However, a residual level of risk will usually remain (unless the hazard is terminated). This is because it may be impractical to treat, terminate or transfer all risks. In addition, those measures upon which reliance is placed to control hazards may fail. For these reasons a crisis management system is needed. Crisis management is a management system with a special structure and process organisation especially designed for the exceptional circumstances of crisis. Examples of this kind of special capability are evident in the general structure of military staffs, and are also found in the police, fire brigade and other emergency protection authorities, security and relief organisations. 3.2 Definition of objectives The primary goal of drinking water suppliers should be to handle a crisis situation potentially affecting drinking water supply in an organised way focussing on the ongoing provision of drinking water in accordance with established statutes and/or regulations. Therefore drinking water suppliers should
 define their objectives based on the relevant national laws, regulations and permits, and  develop an individual crisis management plan by appropriate interpretation of these guidelines. SIST EN 15975-1:2011

- Phase I: transition from incident management to crisis management and preparation for crisis operations (preparation of operations) — Operative crisis management: - Phase II: marked by declaring a state of crisis and convening the crisis management team; comprises intensely pursued crisis control activities. This phase terminates when the end of a crisis is declared and the crisis management team stands down — Follow-up crisis management: - Phase III: a progressive resumption of normal operations takes place (this may include a continuation of the incident below the trigger level for a crisis)
- Normal operations: includes, among other things, a de-briefing of and follow-up on what has been learned, preparation for future crises, additional training etc.
