Measurements of small flow in water service connections
Stehlíková, Veronika ; Ševčík, jiří (referee) ; Tuhovčák, Ladislav (advisor)
In the first part of this thesis the basic information about the losses of water and their reporting are described. There are presented the means and methods of reducing water losses and their suitability for use. Finally, general information about water meters are presented and the UFR device is briefly described. The second part of the thesis is devoted to testing water meter and UFR device on specific water connection in a family house. The thesis resulted in the author's general recommendations for owners and operators of water supply networks.

Reconstruction of the pre-station area in Havířov
Fojtík, Ondřej ; Mikulová, Kateřina (referee) ; Nový, Martin (advisor)
Diploma thesis focuses on the reconstruction of the forecourt area in the city of Havířov. The theoretical part clarifies the concept of project management and its fundamental principles, addressing requirements for construction site equipment and the construction schedule. In the practical section, theoretical knowledge is applied, presenting the reconstruction project itself with a detailed description of its progression. An essential component is the proposal for construction site equipment, including cost estimation, along with the calculation of electricity and water consumption costs. The goal of the thesis is to compare real components of the project with alternative solutions, with an emphasis on potential savings in terms of finances and time.

Assessment of minimal night-flows in the water supply network
Nováková, Jana ; Korabík,, Michal (referee) ; Ručka, Jan (advisor)
This diploma thesis is focused on assessement of the minimum night flow in the water supply system. The first part of the work is focused on the research of foreign and Czech literature in the area of evaluation of water losses in water systems, evaluation and measurement of minimum night flow and comparison of values of individual indicators in the Czech Republic. In the practical part of the thesis, the minimum night flow is estimated and the water losses indicators are determined for selected DMA of Vsetin´s watter supply system, which is operated by VaK Vsetin, a.s.

Demand and Consumption of Water at the Small Water Systems
Klement, Jan ; Svoboda, Pavel (referee) ; Kučera, Tomáš (advisor)
The aim of this work is in selected locations to analyze and calculate the actual value of the maximum daily maximum hourly inequality and inequality in selected locations. At the same time, I wanted to point out this work on outdated design values of the maximum daily and maximum hourly uneven unevenness that may be in the design of new or reconstruction of existing supplied area in small communities to make significant problems with the supply of drinking water.

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 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.

Analysis of Water Consumption in Brno
Růžička, Jaroslav ; Kučera, Tomáš (referee) ; Tuhovčák, Ladislav (advisor)
Water consumption is the amount of water removed by the consumer from water disstribution network. During the transportation inside water disstribution network occur losses. Assesing these losses is one of the main responsibillities of the water supplier. We can show the amount of water lost by using several different methods. Values used to describe the amount of water lost can be often replaced by percentual ratio of water produced to water lossed.

Effects of decreasing water requirements at wastewater treatment plant
Benešová, Irena ; Raček, Jakub (referee) ; Hluštík, Petr (advisor)
Bachelard thesis si aimed on impact and consequences of decreasing water consumption on wastewater treatment plant. The thesis concerns with water consumption in the Czech republic and generally in the world, while particular attention is payed to the hygienic minimum of water supplies to citizens; the causes of decrease of water consumption and its consequent impacts on wastewater treatment plant are mentioned, and further is discussed design of both present and new wastewater treatment plants. The thesis compares different existing approaches to indicate the specific need of water for technological objects of wastewater treatment plants. Part of the thesis was survey on water consumption, possibilities of water savings, and recyclation of grey water. The overlarge objects of wastewater treatment plant are the result of decreasing water consumption.

Pohled veřejnosti na závlahu zemědělských plodin odpadními vodami
Klimešová, Iva
Diploma thesis titled Public view to using sewage irrigation on agricultural crops is divided into two parts: theoretical and practical. First part describes situation about amount of water in the world, in Europe and in Czech republic and also about usage of water in agriculture. Then is definition of waste water and the system of sewage purification a and next utilization. There i salso a few chapters about Czech legislation. Second part include quantitative questionaire which detects the opinion of public on irrigation of arcultural crops by waste water. Analyzing of data helps us to test hypotheses and review with research of Veolia company. In conclusion is evaluation of the thesis and then some references.

Environmental assessment of the Czech Republic based on Water Footprint
Žlábková, Jana ; Hák, Tomáš (advisor) ; Vačkář, David (referee)
This dissertation sets its goal in application of the water footprint indicator, which is a practical and multi-layered indicator of water sources consumption. Of human activities, agriculture presents the most significant demands on water sources consumption. Therefore I have turned my focus to the widely-discussed issue of biofuels production, because the input materials for production of this kind of energy are agricultural crops (in the Czech republic those are: oilseed rape, sugar beet, Indian corn and winter wheat). The calculated results of water footprints of the selected industrial crops (m3 /t) and of water footprints of the heating value units of that crops (m3 /GJ) offer us a concrete notion of energy requirements of water of that chosen industrial crops in the conditions of the Czech republic. Keywords: water footprint indicator, biofuels, oilseed rape, water consumption, biodiesel, bioethanol, evapotranspiration.
