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.

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.

Properties of fine sediments in the water supply network
Dukát, Petr ; Sucháček, Tomáš (referee) ; Ručka, Jan (advisor)
This bachelor’s thesis deals with properties of fine sediments which occur naturally in water supply pipes. With focus on issues of fine sediments samples literature search was made and measurement methodology, which enables better understanding the behavior of sediment in the water supply network, was determined. During controlled pipes flushing, samples of fine sediments were taken from selected water pipes sections and under laboratory conditions sedimentation test, using measurement methodology, was made. Sedimentation test included the measurement of turbidity for the time necessary to meet the limit value of turibidity given by the government regulation for drinking water. Results of this thesis are important input information for simulating the spread of high turbid water in the water supply network during a turbidity event.
