This thesis deals with the water price in relation to the costs of rebuilding of water infrastructure in use. Although the price of water has been very much discussed in the last few years, but mainly in terms of profits. This paper describes the method by which, when using data from property and operating records, it is calculated how much of the gained money should be deferred each year. This amount is for both the whole company and each municipality. As part of this work, I evaluated six water companies and compared the results to each other.

The ways of purifying waste water produced by human society are nowadays a great deal. With the increasing pressure on sustainable construction, technology using principles close to natural processes are at the forefront. Treatment wetlands have been in use for almost 30 years and thanks mainly to developments abroad, they prove they are a suitable option for smaller producers of pollution. When designing a treatment wetland for municipalities with a larger amount of inhabitants, it is necessary to modify the proposal in order to eliminate all types of pollution. This thesis therefore compares three sewage treatment plants with a multistage filtration system. Comparing the achieved parameters will be beneficial for defining the rules for optimal design of these types of wastewater treatment plant.

In the introductory part of this diploma thesis the pesticidal substances and their legislative requirements in drinking water are described. This is followed by a description of technologies in which pesticides can be removed and used in water treatment plants. In the practical part of the thesis is described description of the experimental procedure of the removal of pesticides on two selected adsorption materials (Filtrasorb F100 and Bayoxide E33) and subsequently this experiment is evaluated.

This diploma thesis is divided into two parts, the theoretical and practical part. The theoretical part is to study of factors influencing the workability and bleeding of concrete. There is mentioned the production of cement and standard requirement. The task of the practical part is to assess the cements produced by the cement works Hranice and Prachovice. These cements test in terms of water separation. In combination with these cements use superplasticizing admixtures from Mapei and Stachema and determine the impact of water separation on cement pastes. Determine rheology on the cement pastes. Define influence of variations in cement composition affect the stability of cement mixtures.

There is an opportunity for a new approach to the city adjacent districts by a combination of a reconversion and a modification of the former industrial estate of the Koffiller´s factory with a revitalization of the river Svitava and its feeding canal from an unused island. An introduction of the human spirit into an industrial environment using urban elements, green, public amenities and habitation brings about a better lifestyle.

The diploma thesis is focused on Storm water management in urban areas. The first task for processing thesis was to arrange meeting with MČ Brno - Bohunice Ing. Antonín Crha, who has provided necessary information about the targeted location the and the reservoir for accumulation of rainwater collected. The practical part of the thesis is to capture the rainwater drainage in the existing rainwater sewerage system using the newly built pumping station and then pumping into the existing, unused reservoir. Accumulated water in the reservoir is planned to be used for the needs of the city, gardeners and other customers. The first part of the diploma thesis describes the management of refined water in the Czech Republic, Denmark and Germany. The first part also provides description of measures and technologies for the management of rainwater. Finally, there is description of the pumping station and borehole objects and the program for calculating the rainfall from the urbanized area. In the practical part of the diploma thesis the selected variants are described, rewarded and evaluated. The diploma thesis deals with two variants, that are guided along the same route, with the difference of the construction of the drilled well in the second variant. Both variants are handled by pumping. The option of the gravity inflow was rejected because of the large countersink of rainwater sewerage.

This thesis deals with design of hot water grate boiler, where the output is water with parameters 130 °C and pressure 16 bar. In the content of the whole thesis is gradually introduced a stoichiometric calculations, which is based on the specified fuel – wood chips. This is followed by the design of the individual heating surfaces according to the thermal calculations given in the thesis. Finally, the calculation is extended by hydraulic and aerodynamic losses. Dimensional design, as a basic scheme, is shown at thesis. More detailed drawing documentation is attached to this thesis.

This diploma thesis deals with the efficiency of removal of pharmaceuticals from drinking water by selected adsorption materials. The first part describes sources of pharmaceuticals in drinking water and possible ways of contaminating water by pharmaceuticals. Subsequently, the pharmaceuticals most commonly found in the environment - nonsteroidal anti-inflammatory drugs, antibiotics, psychiatric drugs and sex hormones - are described in more detail. Next, the thesis describes the processes used for removal of pharmaceuticals. These are activated carbon adsorption, membrane processes and advanced oxidation processes. The last chapter of the theoretical part of the thesis deals with water treatment plants, where the technologies for removing drugs are already in operation. In the practical part of this thesis an experiment was performed and evaluated, for a purpose of comparing the efficiency of selected sorption materials in the removal of diclofenac from water. Filtrasorb F100, Bayoxide E33 and GEH were used.

The diploma thesis deals with the use of the electrical impedance spectrometry method (EIS) and the devices Z-meter II, Z-meter III and Z-meter VI based on it for the monitoring earth-fill dams of small water reservoirs. The devices were developed in the Laboratory of Water Management Research of the Institute of Water Structures of the Faculty of Civil Engineering of the Brno University of Technology by solving international project of applied research in the EUREKA program. The analysis of monitoring of the dam of the small water reservoir Bezedník III, which is located in the cadastre of the village Kobeřice, was carried out. Monitoring was carried out from 2006 to 2012. One-off control measurements followed by analysis of achieved results were carried out in 2016, 2018 and 2019.

The development of the chemical and pharmaceutical industry and the massive use of synthetic substances in various industries has become indispensable for our society. Unfortunately, this progress has brought a whole new kind of pollution. It is a group of substances which imagine for living organisms’ greater risk than 'normal' organic pollution. Because they have extraneous origin compared with naturally occurring compounds, they are called "Xenobiotics." It is a group comprising a large number of different substances, with dissimilar physical, chemical and biological properties such as pharmaceuticals, pesticides, detergents, paints, varnishes, plastic packaging, food additives, cosmetic products, drugs, and many others. Although these substances began to enter the water cycle as early as 30 years of the 20th century, their concentration often moves to the limit of the detection limit, so their presence in the water began to be examined in more detail in the 1980s, following the development of analytical technologies chemical composition of water. The main danger of these substances is that doesn’t primarily effect on water quality, but directly affect on the organisms by confusing of the endocrine system or by directly damaging RNA or DNA, causing mutagenic changes, cancer-causing proliferation, birth defects, metabolic disorders, gender changes, the degeneration of reproductive capacity of entire populations or the disappearance of self-preservation instinct. The source of xenobiotics in the water cycle is predominantly wastewater, which generated through the wastewater treatment, which not designed to eliminate this type of pollution. he dissertation thesis deals with the issue of xenobiotics in wastewater and is divided into the theoretical and experimental part. The theoretical part summarizes the xenobiotics current state of knowledge in wastewater from their history, origin, classification, possibilities of elimination to impacts on the environ
