Methodology for the Estimation of the Technical Condition in the Case of Water Treatment Plants

The paper presents the methodology for determining the operating and technical indicators for a preliminary assessment of the elements of water supply system (WSS) such as water treatment plants. The necessary data and system of technical indicators (TI) evaluation using the multi-objective optimization and Failure Mode and Effects Analysis (FMEA) are defined. The proposed methodology allows for the selection and ranking of WSS critical elements for more detailed analyses and suggestions of the type of renewal, including the estimated financial costs. Water treatment plants can be assessed by means of the specific part of the methodology. With respect to the water treatment plants the authors of the methodology realize that it is hard to generalize the entire audit since there are many types of water treatment plants as well as technological elements used. The proposed set of assessment indicators is based on the function of the water treatment plant, i.e. production of drinking water in the required quantity and quality. When assessing the technical condition of the water treatment plant this facility may not be viewed simply in structural and technical terms but it is absolutely necessary and much more important to assess it in technological terms.
