Residential Rainwater Harvesting
Šumichrastová, Mária ; Vendlová, Lucie (referee) ; Wierzbická, Helena (advisor)
The aim of this work is to approach the issue of the use of rainwater in building constructions. This water is widely used for routine activities in the home, which contributes to saving drinking water. At the beginning of my work I focused on what water actually is, and a brief description of each treatment on the basis of their quality. In the first part of about reasons for rainwater management and access to the use of water collection at home and abroad. The second part describes possibilities of application of rainwater in the home. Describes the concept of the need for water, which is essential for the design of the facility. The design of tank is explained in part 3, where I describe the factors affecting the amount of water collected. The following chapters are focusing on individual elements making up the system for the management of rainwater. Chapters are divided according to their function, namely: filter portion, accumulation and a section giving water to the "movement".

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 At the same time, I wanted to point out this work on outdated design values of the maximum daily and maximum hourly uneven unevenness that may be in the design of new or reconstruction of existing supplied area in small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.

Optimization of water management costs during construction
Kramárová, Annamária ; Fazekas, Monika (referee) ; Nový, Martin (advisor)
In the theoretical part, I mentioned the project management of buildings and the construction of prices in construction. In the next section I have described the building site and its water supply requirements. Finally, I have dealt with the cost of water and its consumption. The aim of the thesis was to analyze the influence of water prices on the cost of construction. I transferred this analysis to the model building in the practical part of the thesis. I determined the water consumption during construction, and then I analyzed the impact of the change in water prices on the construction cost.

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.

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.

Rozdíl náročnosti zdrojů (energie, voda) u konvenčního a robotického dojení
TUREK, Tomáš
This paper focuses on the differences in electricity and water consumption between conventional and robotic milking parlours. Data collection from consumers was carried out using a questionnaire method. The developed questionnaire was sent to farms with cattle milk production. From the data collected from the consumers, graphs and tables were created from which individual electricity and water consumption can be determined.

A variety of transpiration in the young spruce stands with different thinning management
Zavadilová, Ina ; Szatniewska, Justyna ; Vágner, Lukáš ; Krejza, Jan ; Pavelka, Marian
Managing the spruce forest growing beyond its favourable conditions is trading between water consumption and increasing biomass. We examined tree transpiration in four stands with different thinning intensities in a 40-year-old spruce forest in South Moravia. Tree transpiration was significantly higher under moderate and heavy intensity compared to low intensity and control plots. Tree transpiration differed also among trees of different sizes within the treatments and also between the treatments. The stem increment was visibly increasing with the intensity of treatment, particularly for suppressed trees. The findings show an ecological tree response two years after the thinning.
