Examples of Reconstruction and Extension of Group Water Supply Systems in The Czech Republic

The paper focuses on the issue of drinking water supply without use of any disinfectants. Before the public water supply network operator begins to consider switching to operation without use of chemical disinfection, initial assessment should be made, whether or not the water supply system in question is suitable for this type of operation. The assessment is performed by applying the decision algorithm. The initial assessment is followed by another decision algorithm which serves for managing and controlling the process of switching to drinking water supply without use of a disinfectant. The paper also summarizes previous experience and knowledge of this way operated public water supply systems in the Czech Republic.

Supply Systems

Group water supply systems (GWSS) are designed for centralized water supply of settlements located in waterless areas and remote from drinking water sources. GWSS are an object of increased attention, have a great social and environmental significance, require significant capital investments and financial resources for operation, ensuring the required reliability and manageability. Therefore, the issues of optimization of design solutions for the structure and parameters of structures are relevant and require improvement and development of methodological and software solutions to these problems. The paper proposes a method of redundant design schemes and a method of schematic and structural optimization based on a sequential and iterative solution of two problems: for a fixed value of flows in the graph of the redundant scheme, network parameters are optimized (pipeline diameters, heads, and the composition of pumping stations); with fixed network parameters, the problem of the distribution of water flows is solved in the GWSS.

This paper deals with a comparative analysis and benchmarking of drinking water supply systems and water supply sector in the selected countries of Central and Eastern Europe. These include the Czech Republic, Poland, Romania, and Slovakia. The article provides an analysis of existing benchmarking systems in each country. Methods of supervision and control over the assessment and the functioning of the organizations responsible for the assessment and benchmarking of water utilities are also described. Comparative analysis for the selected performance indicators is carried out. The units, methods of data collection and processing were described.

Supply Systems

In recent years, in the Russian cities there has been a decrease about 15-30% the total volume of water consumed and the specific indicator of water consumption per resident. However, this phenomenon is not taken into account in the SP 31.13330.2012, therefore the values of specific water consumption do not correspond to the modern level of sanitary equipment of the buildings and water consumption, which can not be the same for all cities and towns in Russia. Using the standard values of the design loads indicated in this code can lead to a significant increase in the cost of the project and operating costs. Their correction is necessary taking into account the assessment and forecast of the actual values of specific water consumption. This requires appropriate research and updating of specific water consumption standards for the design and reconstruction water supply and sewerage systems. The article describes the parameter justification method for the designed water supply systems under uncertainty of the prospective values of specific water consumption. The technique is based on the fuzzy sets theory and decision-making methodology under uncertainty of the initial information. This technique allows you to make decisions based on the minimum values of investment risks.
