Assessment of minimal night-flows in the water supply systems
Zvejška, Tomáš ; Tuhovčák, Ladislav (referee) ; Ručka, Jan (advisor)
This Diploma thesis deals with minimum night flows issue. Basic findings about minimum night flows were summarized in the introductory part of thesis. Findings like the minimum night flow components, affecting parameters and used methodologies for assessment of minimal night flows. In the practical part of this thesis was this knowledge applied to real water distribution system in the municipality Hrádek u Sušice. The part of this thesis was also determinate the measurement accuracy of used water meter, which was formerly installed at the outlet in the Hrádek water tank. Measurement errors was determinate for the flow values, that are close to the real measured minimum night flow data in the water distribution system in municipality Hrádek u Sušice.

Energy Audit od Water Supply Systems
Krupa, Filip ; Viščor,, Pavel (referee) ; Tuhovčák, Ladislav (advisor)
This Disertation deals with energetical audit of aqueduct. First part is dedicated to the current status in Czech Republic, but expecially abroad. Other part processes structure of energetical audit according to the knowledge gained and also from academic articles and set up an example, where this audit is made. Firts variant is energetically intensive water line and other variant is nergetically economical. Last part id dedicated to perform an energetical audit on real water line in Kateřinice village, Vsetín district.

Risk Analysis for Intermittent Water Supply Systems
Alayoubi, Mzayan ; Říha, Jaromír (referee) ; Munka,, Karol (referee) ; Tuhovčák, Ladislav (advisor)
Intermitted Water Supply strategy is implemented commonly in some developing countries nowadays in order to minimize the water scarcity problems. Unstable hydraulic conditions in the distribution system, low pressure, high risk of water contamination, wasting water, rising costs paid by consumers and water providers, failures and problems with consumption metering and inconvenience to consumers are some of the consequences. Risk Analysis Methodology is developed to handle with intermittent water supply systems in developing countries conditions that include undesired events identification; risk estimation and risk evaluation and reduction plan, the catalogue list of potential undesired events (UE) which may occur in these types of systems have been also developed using the HAZard and OPerability technique (HAZOP). The developed methodology is implemented and tested in this research on one of the potential undesired events UE _ Low operational pressure

Technical Audit of Water Distribution Network
Haman, Michal ; Ručka, Jan (referee) ; Tuhovčák, Ladislav (advisor)
This diploma thesis deals with the topic the assessment of the technical condition of water supply networks. Part of the work is a case study that evaluates the technical condition of the water supply network in the city district Brno-Lisen. The work describes in detail how the pressure zones and selected water mains evaluated. The output is an Excel application, which can be set according to technical indicators carry out an evaluation of the technical condition of the individual pressure zones.

Smart Metering of Water Supply System at Campus of Faculty of Civil Engineering BUT
Černíková, Eva ; Ručka, Jan (referee) ; Tuhovčák, Ladislav (advisor)
The aim of this thesis is to perform an analysis of possibilities and benefits of installing the Smart Water Metering technology at campus of Faculty of Civil Engineering, Brno University of Technology. The main goal was to provide specific solutions of Smart Metering systems from different companies. One part of this thesis is dedicated to a detailed analysis of a water consumption measurement campaign that took place at the beginning of this academic year using dataloggers. Real-time flow rate and consumed volume was recorded every five minutes. Therefore it was possible to determine water consumption patterns during the day and also tell the minimum, maximum and average flow rate in different parts of the campus. Thanks to these measurements, irregular water consumption during the night was observed. This would not have been easily detected without recording real-time data. This system of recording real-time flow rates with dataloggers is considered to be suitable for the needs of faculty. Thanks to a GSM module, recorded values are sent to an FTP server once a day. From there the data can be downloaded to any kind of analysis software. Installation of Smart Water Metering technology at campus of Faculty of Civil Engineering would be beneficial for both operation of the water supply network and also for purposes of an academic research.

Technical Audit of Water Tanks
Šlesinger, Jan ; Svoboda,, Miroslav (referee) ; Tuhovčák, Ladislav (advisor)
This diploma thesis aims to design a methodology for technical audit of water tanks. The first part presents basic information on water tanks, followed by a brief summary of Czech legislation related to developing water tank renewal financing plans. The key part of the thesis is designing the structure of TEAA water tanks module, which will be included in TEA Water methodology, being developed at Institute of Municipal Water Management. The module under proposal is implemented as a MS Excel application, which is used to assess selected water tanks. The assessment results are compared to results obtained using TEA Water web application, which implements a draft of the TEAA module from October 2014, and to the results obtained using TAWAT.xls application.

Energy audit of water supply
Pavliš, Jan ; Tuhovčák, Ladislav (referee) ; Kučera, Tomáš (advisor)
This document aims on presentation of energy audit of water networks. Its focus is to introduce the method of solving the energy audit of water networks. It characterizes the water networks performance using context and efficiency indicators. It consists of theoretical description of mathematical approach to the problem. It describes different kinds of energies participating in water distribution process and also presents energy indicators which describe energetic efficiency of water networks. Last but not least it shows the possibilities of accomplishment the energy audit of water network on numerical example. Then we can find the assessment of each of indicators and kinds of energies. Context indicators describe topography of water network and efficiency indicators show how efficient in terms of using input energy is the behavior of the water networks. The case application of the approach of solving energy audit of water networks as well as indicators assessment can be found in the last part of the thesis. This thesis brings basic overview of the approach to the solution of energy audit of water networks. May it help the future application of the energy audit of water networks in the Czech Republic.
