Long term planning of water distribution network rehabilitation
Hos, Lukáš ; Kučera, Tomáš (referee) ; Tuhovčák, Ladislav (advisor)
This diploma thesis is about long-term rehabilitation planning of water distribution system. First part is about legislative demands on rehabilitation planning in Czech Republic and about methods used abroad to do long-term reahabilitation planning. Second part of thesis is about own created method based on TEA Water (application about condtition assessment of water supply infrastructure). This method is tested on fictional water network and on real water network of Babice nad Svitavou.

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.

Benchmarking of Water Utilities in Czech Republic
Hájek, Břetislav ; Sucháček, Tomáš (referee) ; Tuhovčák, Ladislav (advisor)
This Bachelor thesis is focused on knowledge of benchmarking of water companies with performance indicators. The main task is to to gather basic and complementrary indicators into the Excel table, which calculates performance indicators. All indicators are then rewritten into the WaBe web application. Data are collected from the company’s annual reports, which are downloadable on the website of the Ministry of Justice www.justice.org, where companies are required to submit their annual reports. The first part of the bachelor thesis is a description of benchmarking and the companies that do it in water industry as foreign companies (IWA, EBC, IBNET, EurEau, AWWA, WRF) as well as the czech organizations (SOVAK, Ministry of Agriculture, WaBe). In the second part is the presentation and analysis of selected water companies. For the selected indicatorsis made comparsion with graphs created in Excel.

Multi-objective condition assessment of selected parts of water distribution systems
Tauš, Miloslav ; Svoboda,, Miroslav (referee) ; Kriš,, Jozef (referee) ; Tuhovčák, Ladislav (advisor)
The topic of the thesis is multi objective condition assessment of water supply systems. The state of the art of condition assessment of water supply systems and the state of the art of multi objective optimization methods are presented within the thesis. Based on these recherches, the uniform methodology of condition assessment of water supply systems and its 7 modules was designed. The thesis deals with the selected modules to condition assessment of water pumping stations, water networks and pipe sections. The output of the methodology is the assignment of a category of the technical condition to the rated object. The proposed methodology was tested on real water facilities and proves the ability of a fair presentation of the technical condition of the object.

Optimisation of pressure condition in water supply systems
Sucháček, Tomáš ; Svoboda,, Miroslav (referee) ; Pollert, Jaroslav (referee) ; Tuhovčák, Ladislav (advisor)
This thesis is focused on the optimization of pressure conditions in the water supply network. There is a deep theoretical and critical search of the state of the art and there are fields where there is an insufficient field of knowledge, the so-called "knowledge gap". Experiments are proposed here to determine the dependence of water consumption on pressure conditions. There is a description of experiments and way how it was carried out, which were carried out on the water connection, in the pressure zone and in the laboratory on the hydraulic loop. There is proposed a methodology of experimental determination of the mathematical dependence of water consumption on pressure so that it can be used for optimization problems, where consumption is considered as an optimization criterion. The results of individual experiments are evaluated and a critical discussion of the achieved results is carried out. Finally, the achieved results are compared with the values found in a deep literature search.

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.

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.
