Water temperature in the water supply network
Veniger, Jan ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
The bachelor thesis deals with the analysis of water temperature in the water supply network of the municipalities of Kanice and Řícmanice. These are municipalities located in the South Moravian Region, in the district of Brno-venkov. First, the available literature that was used in the data processing is described. For the purpose of temperature measurements, the Astacus technology used by Voda Brno, s.r.o. for controlled flushing of water pipes was used. Furthermore, the water temperature distribution along the length of the pipeline on individual parts of the water supply lines is described. In the last part of the paper the influence of the assessed factors on the water temperature is discussed.

Design and Operation of Water Disinfections Plants
Krupicová, Simona ; Rajnochová, Markéta (referee) ; Kučera, Tomáš (advisor)
In the first part of my bachelor thesis I deal with individual disinfectants used for hygienic supply of drinking water based on chlorine and without chlorine. Then I mention the operation without chlorine disinfectants. In the second part of this thesis I describe individual plants using various disinfection methods and at the end of the thesis I compare these methods and use it in practice.

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.

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.

Simulation of the chlorine concentration in the water-supply network
Rajnochová, Markéta ; Biela, Renata (referee) ; Ručka, Jan (advisor)
The Bachelor thesis is focused on simulation of the concentration of free chlorine in the water supply network of the village of Kateřinice. For the simulation, the EPANET 2.0 software tool was used for construction of a mathematical simulation model for the existing water supply network of the village. Subsequently, the model was calibrated and verified on the basis of data obtained from the measurement of water quality in the distribution network. The aim was to calibrate the simulation model of water quality so as to best simulate the concentration of free chlorine in all areas of the village’s water supply network. Also, the optimal dose of chlorine for the village was determined using the model. Furthermore, in the bachelor thesis it was examined if controlled flushing has an impact on the rate of decay of free chlorine.

Water supply without a residual disinfectant
Rajnochová, Markéta ; Pikal, Martin (referee) ; Ručka, Jan (advisor)
The diploma thesis focuses on the water distribution system functioning without chlorine-based disinfectant. This thesis contains research of documented cases of examples of drinking water distribution systems both abroad and in the Czech Republic, which do not use disinfectants. Moreover, the thesis pay attention to chlorine and its effects on bacteria. The thesis deals with the first assessment of water supply structure, which determines whether the water supply structure is suitable for operating without disinfectant. The thesis describes the process of transition to the disinfectant-free operation and determines the undesired events, which may occur with the ending of the use of disinfectant. As a part of the research, the thesis examines the water supply system in village Kateřinice, to determine if it is suitable for operation without disinfectant.

Model solution for rainwater management in selected types of residential buildings
Šoustal, Michal ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
The bachelor's thesis contains a model solution for rainwater management, where certain measures are proposed for selected types of residential buildings. Its aim is to propose the economic use of precipitation for the benefit of the population and the environment. The introductory part is acquainted with water supply networks, rainwater quality and legal legislation. The theoretical part describes the individual infiltration and retention devices that are used today. The following are mathematical methods and procedures that have been applied in the research. The theoretical part also describes possible subsidy programs for the use of financial support for rainwater capture. The research began with a survey and then an analysis of the public and private space in which the buildings are located and the remaining data were performed from ČSN standards. In the practical part, hydrometeorological calculations were performed, then according to the identified legal requirements, measures were subsequently proposed for implementation. The indicative budget of the proposed measures was prepared by calculating aggregated RTS prices. Followed by subsidy contributions, which may cover part of the costs of the measures created.

Assessment of pressure conditions in the water supply network of the municipality of Ústí
Kuchař, Jakub ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
The bachelor's thesis is devoted to the hydraulic analysis of the water supply network of the municipalities of Ústí, Skalička and the settlement of Kamenec. The village is located in the Přerov district. The first chapter describes the theory of mathematical modeling and the basic relationships for calculation in pressure pipe systems. A quasi-dynamic hydraulic model of the entire area was created from the measured pressure values of the water supply network. The assessed values were displayed in the EPANET 2.2 simulation program. With regard to the character of the development in the municipalities, the pressure conditions in the area were assessed using the result. The last part of the work is dedicated to proposing measures to optimize pressure conditions and the resulting impact on the territory.
