Opis:: Water supply system is complicated technical system which belongs to underground urban infrastructure. Its accurate functioning determines everyday live stability of citizens. Risk analysis is a key phase of the process of water supply safety management. The aim of this paper is to present new propose of methods for risk of the first type (associated with quantity of supplied water) and the risk of the second type (associated with quality of supplied water) analyses in water supply system. The paper contains the description of matrix methods for risk analyses and methods describing cause-and-effect relationship of failure events (fault tree analysis).

Opis:: The subject and main purpose of this study is to present the method of risk analysis and assessment of the lack of water supply to the collective water supply system (CWSS). Presented method using the expected value of water scarcity. The analysis was based on all possible states of the operation of water production subsystem. The article contains calculation example of analysis for the exemplary CWSS with regard to absolute risk, equal to the expected value of water scarcity and the relative risk referred to the nominal value of the water demand. In the example attached special importance to the criteria levels of the relative risk of lack of water supply. Presented method is a new concept which allows to make comprehensive analysis of reliability, safety and operation of the collective water supply system.

Opis:: The subject and main purpose of this study is to develop risk analytic model for the design and operation of water supply sector. A water supply system belongs to the critical infrastructure of cities, and it should be a priority task for waterworks and even for the local authorities to ensure the suitable level of its safety. A water supply systems (WSS) ought to be high reliable continuous operating system. Failure factors in WSS should be identified and prioritized, for example, the causing factors in the most frequent failures in waterpipe network. Drinking water supply utilities are responsible for providing a safe and reliable supply of potable water to their customers. Risk priority helps asset manager to target and refine maintenance plans, capital expenditure plans, investigative activities, and deal with potential failure before it occurs. In this paper, we present a review of classic risk analyses, risk management and new methodology for water supply networks management. This paper presents a framework for the analysis of performance risk in water supply that can be applied to the entire system or to individual subsystems. It is expecting that the methodology for the water supply performance risk analysis would provide the city leadership for decision making support.

Opis:: Water quality control from the perspective of water supply system users’ safety contributed to create drinking water production and quality control procedures. Contemporary risk hazard analysis should be performed on the stage of production, distribution and storage of tap water. Sequences of undesirable events are considered in the so-called waterworks chain series. This leads to critical control points and gives the ability to provide current control over the processes in the collective water supply system, as well as of their combinations and mutual interactions. Methodology of water consumers protection against incidental pollutions was shown. Algorithm concerning identification of critical control points – CCP was developed .The rules of safety related system into drinking water production have been shown. Also risk assessment using the tree event method was presented.
