Abstract

Over the past years in Central and Eastern Europe, including Poland, it can be observed that there has been a considerable decrease in water consumption. This leads to high operational costs due to underutilised capacity of existing drinking water treatment plants (DWTP) or distribution systems. Under these conditions providing rational management of DWTP requires technical, economical and reliability analysis. The application of probability and statistical theories together with a decomposition method was the scientific basis of this paper. As a second step, Woodward’s LCCA model, together with the Activity Based Costing (ABC) model, were applied. Keywords: risk, reliability, operation costs, life cycle cost(ing).

Keywords
