Lead connections impact on quality of drinking water
Vostrčilová, Markéta ; Sucháček, Tomáš (referee) ; Biela, Renata (advisor)
The thesis is divided into several parts. First, materials of water supply connections are discussed, which are used today and have been used in the past. Further, it discusses the basic characteristics of lead, lead connections and lead in drinking water. The next chapter describes the development and current legislative requirement for lead content in drinking water. Subsequently it describes risks lead to the organism. The penultimate part consists of an evaluation questionnaire forms on the topic of lead connections, which were filled by water companies. Finally specific data on lead content in drinking water are listed and described from two water companies and selected health institutions.

Hydraulic analysis of small water supply system
Sucháček, Tomáš ; Kučera, Tomáš (referee) ; Ručka, Jan (advisor)
This document aims on aplication of sophisticated software programs to accomplish hydraulic analysis of real water supply. In this work is stated a list and description of software enabling to accomplish static or long-term hydraulic analysis of water supply when the most world used program EPANET 2.0 is described more deeply. There is described working of a EPANET and his algorithm also there are explain principles on which EPANET is based. During the hydraulic analysis of real system was used two sophisticated software it were MikeNet and EPANET 2.0. With using these two sophisticated programs was processed hydraulic analysis of chosen water supply of small consumption area, during this analysis was studied influence of method distribution node´s demand on achieved results also was created map of velocity in water pipeline. This work is first step for continuing Master´s thesis which will be using results of hydraulic analysis for create plan of elimination sludge in water supply.

Optimisation of Pressure Condition in water Distribution Networks
Straňák, Petr ; Sucháček, Tomáš (referee) ; Tuhovčák, Ladislav (advisor)
The bachelor thesis deals with pressure in the water distribution network. The introductory chapter describes legislative requirements for network pressures and means of network auditing. The following chapter deals with the optimization of pressure conditions in the water distribution network, describes the positive and negative aspects of pressure optimization, illustrates ways of influencing pressures, and briefly analyzes existing case studies from abroad. In the final chapter, with the help of the EPANET 2.0 program, pressure optimization is performed on the fictional network.

Water consumption in selected subjects
Jedličková, Tereza ; Sucháček, Tomáš (referee) ; Kučera, Tomáš (advisor)
The aim of the theoretical part of the bachelor thesis is to define the basic concepts related to the need and consumption of water. The following terms are explained: average daily water demand, maximum daily and maximum hourly water demand. The thesis also deals with water flow measurement. Among other things several types of flow meters are described here. In the practical part of the bachelor thesis, water consumption and water prices are analyzed in three selected agricultural cooperatives. There are compared individual agricultural cooperatives. Part of the thesis is also the determination of the average value of water consumption per cow.

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.

Impact of pressure condition on water consuption in water distribution network
Straňák, Petr ; Sucháček, Tomáš (referee) ; Tuhovčák, Ladislav (advisor)
The diploma thesis deals with effect of pressure conditions in the water supply network on consumption of drinking water. The introductory part describes how pressures affect water consumption and six studies from different countries carried out on real network are presented. Further, the work is devoted to other factors influencing water consumption and distribution of domestic water consumption. The practical part deals with the laboratory measurement of the influence of pressure change on tested discharge fittings for flowing and dripping water. The results are also expressed in annual costs and a method is presented how the effect of pressure change can be quantified if we know the average daily consumption and its distribution.

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.
