Feasibility Study on Quantitative Risk Analysis of Drinking Water Networks

Quantitative risk analysis is used by various water companies, but mainly for aboveground assets for water treatment and pumping. Quantitative risk analysis is less frequently practiced for underground water distribution networks, as the condition of mains and the possible consequences of failures are difficult to predict. Nowadays, quantitative risk analysis for water distribution networks is a logical step forward as more (geographical) information becomes available and links can be made with computer models. Recent research by Kiwa Water Research executed for the Joint Research Programme of the Dutch drinking water companies, made clear that quantitative risk analysis is a feasible method for identifying critical mains sections in water distribution networks. The next step will be to investigate how quantitative risk analysis for distribution networks is to be implemented efficiently.
