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.

Variants of sewerage of municipalities to 2000 inhabitants
Remešová, Terezie ; Ručka, Jan (referee) ; Raclavský, Jaroslav (advisor)
The main goal of this thesis is a proposal and a comparing potential options about drainage of village Bořetice. Proposed variants are building of a new sewer network and a pump station according to PRVK, building of a new sewer network and a sewage treatment plant and a building of a new sewer network with a finishing wastewater treatment in the stabilization tanks. This thesis also includes a summary of current options of drainage village up to 2000 inhabitants.

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.

Minimum slope on the sewerage system
Vašková, Kamila ; Ručka, Jan (referee) ; Hluštík, Petr (advisor)
The bachelor thesis deals with the comparison of calculation methods to determine the minimum slope on sewerage systems. The thesis compares the calculation methods specified in ČSN 75 6101 and also the city standards of larger cities in the Czech Republic. When the comparison is carried out, it is distinguished whether that is a single, sanitary or storm sewer. The comparison is carried out according to available sewer material options and the sizes of sewer profiles.

Design of the Střížov sewer network
Vrána, Radek ; Úterský, Michal (referee) ; Ručka, Jan (advisor)
The aim of this bachelor's thesis is to elaborate the proposal technical design of the drainage village Střížov by combined sewer network. The first part deals about the area of interest. In the next part the thesis deals with the design and description of the location of sewer with respect to crossing with existing utility lines. It is also processed hydrotechnical situation of dewatered area and detailed longitudinal profile of the main collector.

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.
