Assessment of drinking water consumption in the water supply network of the Valašské Meziříčí
Fučík, David ; Libosvár, Dušan (referee) ; Ručka, Jan (advisor)
This diploma thesis deals with the analysis of the time series of drains from the water reservoir and evaluation of the minimum night flow in the water supply network of the town of Valašské Meziříčí. In the theoretical part of this thesis were elaborated research of Czech and foreign literature focusing on drinking water consumption analysis, measurement and evaluation of minimum night flow and methods of determination of water losses in distribution systems. The practical part includes analysis of water outflows from reservoirs, evaluation of minimum night flow and determination of basic water loss indicators for selected district metered areas of the network. The above-mentioned water supply network is operated by the Vak Vsetín, a.s.

Sanitation installation and gas installation in a multifunctional building
Peřinová, Jitka ; Vaščáková, Alena (referee) ; Vrána, Jakub (advisor)
The task of the Bachelor's thesis is to develop a design of sanitary and gas installations in a given multifunctional building. The building has no basement and has four floors. In the first floor there is a bistro and a accommodation in the second floor. One dwelling unit is spread over the third and fourth floors. The theoretical part focuses on grease traps. I focus on their main functions, the choice of nominal size, montage and types of traps. The computational part contains all calculations used in the design of sewerage, water and gas pipelines, including their connection to utilities.

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.

Impact of drought on drinking water supply
Bergerová, Marie ; Sucháček, Tomáš (referee) ; Ručka, Jan (advisor)
This bachelor thesis deals with the issue of water age in the distribution system of drinking water supply. Various scenarios were simulated, which represented a reduction in water consumption due to the replacement of part of drinking water with rainwater. In first part, various definitions of drought and possible effects of drought are presented. The second part is focused on the consumption of water from the water supply network. The uses of drinking water in the household are defined here, but also an indication is included which household activities do not need to use drinking water, which can be replaced with rainwater. The practical part describes an analysis of water age. Not only was the analysis processed for different scenarios, these scenarios were also compared for different times of the year, including the annual average, the summer period (July, August) and the winter period (January, February). The analysis was performed using the Epanet 2.0 software program. In processing the results of the water age analysis, the relationship between water age, velocity, flow rate and pressure ratios were evaluted.

Hydraulic analysis of the water supply network of the municipality of Ostopovice
Jaroš, Zdeněk ; Sucháček, Tomáš (referee) ; Ručka, Jan (advisor)
The theses focuses on a hydraulic analysis of a water supply network of a village called Ostopovice, located in South Moravia. Theses presents a detailed quasi-dynamic hydraulic simulation of the water supply network based on own consumer field survey. Subsequently, the assembled model was calibrated and verified by hydraulic data measured on the water supply network. The model was made to simulate characteristic water supply system operating conditions. Using the hydraulic analysis results, the theses assesses network pressure conditions with regards to the existing building range and type, taking into the account the extent of expected house development of the area. The work concludes with a proposition for measures leading to the water supply network pressure conditions optimization.
