Abstract

The paper presents issues related to ensuring the safety of water supply, based on the analysis and assessment of the risk of the lack of water supply to consumers using risk maps, in accordance with the current global trend recommended by guidelines and procedures, compliance with which should be a priority activity in the struggle against adverse events, related to the functioning of every collective water supply system (CWSS). The work contribution is the development of an original methodology of risk analysis and assessment for the needs of mapping the risk of a lack of water supply in the normal operation of the water supply network, as well as during a crisis. The presented methods take into account the quantitative aspect of the lack of water supply, with the possibility of extending the proposed solutions with a qualitative aspect. The article will contribute to the development of knowledge in the area of analysis and assessment of the risk of a water supply failure in PsDyW, and will determine new standards in its graphical presentation. It is a response to the World Health Organization (WHO) requirements of providing protection for the critical infrastructure and ensuring access to water for all citizens in the European Union.

Summary

Introduction

Most people in the European Union (EU) have access to high-quality drinking water, especially if we compare European countries to other regions of the world. The fact that access to safe drinking water and sanitation is inextricably linked to the right to life, human dignity and the requirement to ensure a fair standard of living, has been noticed by the World Health Organization (WHO) It was confirmed by the opening words of the 4th edition of the WHO guidelines on the quality of drinking water, recommending the creation and implementation of water safety plans (WSP) [7]: the most effective means of consistently ensuring the safety of a drinkingwater supply is through the use of a comprehensive risk assessment and risk management approach that encompasses all steps in the water supply from catchment to consumer. In these guidelines, such approaches are termed water safety plans (WSPs)
