Assessment of the Reliability-Cost Efficiency of the Pumping Subsystems at Water Treatment Plant

Abstract

Abstract:In last years all countries of the European Union experience decrease of water consumption. What is worse, in most cases large European water treatment plants (WTP) have been design and built decades ago, when water consumption was much higher than nowadays. It is a challenging task to adjust WTP's capacity to the current water demand as it is associated with costs and safety issues. Minding that fact, authors decided to propose an new authorial methodology of combined reliability-cost efficiency assessment for water supply system with exceeded redundant capacity, based on new index -unit indicator of reliability-cost efficiency. It included both reliability and costs aspects. It was decided to present the new method on example of the pumping subsystems working for WTP in Poland. The research was based on Activity-Based Life Cycle Costs (AB-LCC) methodology together with two-parametric reliability evaluation. Using real operational and financial data an application of proposed authorial reliability-cost indicator was presented. The reliability-cost efficiency assessment allowed to present how operation of each pumping subsystem influenced global operational costs of WTP. This information is essential for decision-making process for rational management of technical facilities.

Smart specialization as a factor stimulating innovative development of water and wastewater economy

“…In this scope, it is important to set proper directions of R&D and innovative works. Introduction of innovations in the scope of, inter alia, water recycling and reuse of water in the water industry can bring multiple benefits for sustainable development [13]. An aspect significant for the purpose of increase the water technology development opportunities is cooperation that must be based on network and cluster relations between the various participants of this process at all the different levels.…”
