Opis:: In paper the methods of comprehensive analysis of reliability, safety and operation of the water supply system were presented. The main goal of this work is to present the problems associated with the WSS functioning in terms of belonging to critical infrastructure. The analysis of the WSS functioning in face of emergency events occurrence should be one of the priority actions taken by the water companies. The paper presents an application of reliability and safety analysis of water supply in emergency situations.

Opis:: Drinking Water Supply Service is considered vital in all societies, modern and old. As for all vital services, governance undertakes all possible measures to guarantee their supply continuity. However, severe service supply disruptions may occur under the action of threats, series of failures cascading or any combination of them. Threats may be nature originated: climatic extreme conditions, earthquakes, floods. It may also be man originated: ill-informed managing actions, organisational misconduct or malevolence. As for failures, it can be humans or simply systemic: unproven technology, fatigue, ageing, overloading or operational hazards. Whatever the origins of the disruptions, societies conceive legislations, standards and processes in order to enhance the resilience of the vital service supply systems and the correspondent critical infrastructures. They provide appropriate R&D frames and assets, amongst others, in order to conduct activities on critical infrastructures resilience modelling, simulation and analysis (MS&A). The paper contributes into the development of a resilience concept and a methodology for integrating cascades of failures to help in crisis management decision making. The proposed methodology is applied on a case study belonging to the drinking Water Supply Services and its critical infrastructures.

Tytuł:: Failure risk analysis in the collective water supply systems in crisis situations

Opis:: Risk is a basic category to estimate water supply system safety. The first step in risk assessment is to identify the threats and their possible consequences. One of methods for risk assessment is the method using the socalled risk graphs. It relies on the preliminary analysis of such risk factors as: the frequency of threat occurrence – F, the duration of the risk exposure – E, the size of the possible consequences – C and a degree of protection – O, that is inversely proportional to the mentioned measures of risk. The route along the branches of the risk graph should be started from the determination of the initiating/peak event which is the undesirable event (e.g. secondary water contamination in water-pipe network). The expanded risk graph presented in the work differs from the standard (commonly used) graph because it takes into consideration all combinations of the particular risk factors.

Tytuł:: Safety of water supply in crisis conditions

Tematy:: water supply system
risk index

water supply safety levels
threat identification
Opis:: The paper presents the concept of safety in water distribution systems, which is an important issue connected with its functioning in crisis situations. The research undertaken is directed towards methods of safety assessment relating closely to current world trends, aiming to ensure safety of water supply and use. The paper pays special attention to water consumer safety. Safety levels were assumed on the basis of failure intensity, exposure of water consumers and a number of undesirable event groups. Individual values of the immediate risk index were presented and three categories were distinguished as permissible, tolerable, or unacceptable risk categories, according to presumed action. The risk index can characterize the safety of the functioning of technical systems. The risk index definition is considered as the product of threat ranking. The paper contains the original proposal for a new method of risk analysis and assessment.
