Matrix Analysis of Risk of Interruptions in Water Supply in Terms of Consumer Safety / MATRYCOWA ANALIZA RYZYKA PRZERW W DOSTAWIE WODY W ASPEKCIE BEZPIECZE?STWA KONSUMENTóW WODY
With regard to drinking water consumers, safety is understood as a probability to avoid threat arising from the consumption of water inconsistent with quality standards or the lack of water. Accordance with the Regulation of the Minister of Health water is safe for human health, if it is free from pathogenic microorganisms and parasites in the amount constituting a potential threat to human health, any substances in quantities hazardous to health and has no aggressive corrosive properties. Water supply reliability means providing stable conditions allowing to meet current and future demand for water in sufficient quantity and with required quality, in convenient time for water consumers and also at a price acceptable by them. In this study consumer (individual) risk rK was defined as the sum of the first kind of risk rKI, associated with possibility of interruptions in water supply and the second kind of risk rKII associated with possibility of consumption of water inconsistent with quality standards. Three-parameter matrix of risk was proposed. For presented method was made an application example based on exploitation data of collective water supply system, which may help to increase safety of water consumers.
