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.

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.

Analysis of water age in the water supply network of a selected area
Pellarová, Tereza ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
The bachelor thesis deals with the issue of water age in drinking water distribution system. The theoretical part discusses the factors influencing the age of water and the quality of delivered water, and also the way in which the age influences the quality of water. Furthermore, the methods of age determination are mentioned, as well as indicators of high age. The consumption of mains water and water prices in Europe are also discussed. The practical part of the thesis focuses on the analysis of the age of water in the water supply system. The data needed for the analysis was obtained by means of the EPANET 2.2 tool, in which simulations were performed for periods with different water consumption, including the annual average, summer (July, August) and winter (January, February). After the simulation, the data were entered into MS Excel and then statistically processed and evaluated. The aim of the practical part was to find the correlations of the factors acting in the network. The age/velocity and age/flow rate were examined in the water main sections. The relations between age/consumption from the nodes and age/pressure were examined in the nodes of the network. All data were monitored within the constant age intervals occurring in the municipality´s shared water supply system.

Analysis of Water Consumption
Pokorná, Denisa ; Ručka, Jan (referee) ; Tuhovčák, Ladislav (advisor)
The subject of the bachelor thesis is the processing of water consumption analysis in the area of building faculty. The bulk of the work is devoted to the evaluation of the data obtained by the smart metering system, which is currently only installed on the billing water meter number 2 located on Veveří Street. The Faculty of Civil Engineering is very interested in new trends and possibilities to more effectively measure water consumption. The conclusion of the thesis deals with the appropriate design of the alarm values of consumption and the possible counting of other water meters in the area and associated faster and more transparent information about the water consumption values. An integral part of the work and water consumption are general information on the need for water for which there are no up-to-date comprehensive methodologies to accurately determine it. Analyzing already measured data seems to be the most accurate way of determining it. Part of the thesis is also a chapter focused on the development of water consumption in our country as well as in comparison with abroad. At present, there is a decreasing trend in water needs that began in the 1990s.

Modeling of water quality in the water supply network
Dukát, Petr ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
This thesis looks at water quality modelling in the water network, focusing on water age. The initial part of the work identifies the factors that lead to an increase in water age in water supply networks. The theoretical part of the work presents the mathematical relationships and logistical steps that software tools apply to simulate water quality indicators in a water supply network. In the practical part of the work, a hydraulic model of a water distribution system with a total length of 302,1 km was constructed. Measurement campaign was carried out to calibrate and verify created hydraulic model. Using this hydraulic model, water age for existing and possible scenarios was simulated. The results of the work have revealed parts of the water supply network containing high water age and are intended to encourage the progressive water distribution systems management philosophy.
