Rainwater-treatment and rainwater utilization
Štefek, Miroslav ; Kárník, Jan (referee) ; Štigler, Jaroslav (advisor)
The aim of this bachelor thesis is developing searches which are focused to treatment with rainwater and it's next utilization. We can find general information about situation in Czech Republic in this work and we can also read about products for rainwater treatment which are available in the market. There is a calculation for house too where we can see if it is advantageous step if we'll purchase rainwater treatment products.

Study and characterization of organic substances in a biochar sample
Vojáčková, Beáta ; Kalina, Michal (referee) ; Enev, Vojtěch (advisor)
This bachelor thesis characterizes biochar from a physico-chemical point of view. The theoretical part deals with biochar as a soil conditioner, its properties, use, production, and last but not least, effect of its sorroundings. For better characterization of organic and inorganic matter a phosphate buffer was used. This buffer ensures their specific extraction due to a neutral pH. The second path is to use rainwater, which simulates the condition of the soil environment. In the experimental part are discussed both; purified buffer-extracted samples and rainwater samples, which were studied by thermogravimetric analysis (TGA), elemental analysis (EA) and by infrared spectroscopy with Fouier transform (FTIR-ATR). Conductivity and pH were also measured. Moisture and ash content, which represent the inorganic non-combustible fraction, were determined using thermogravimetry. The extraction yields were converted to ashless wt. % based on these values. Results of EA provided us with information on the content of biogenic elements and basic physico-chemical characteristics of biochar. In contrast, the FTIR method defined the presence of individual functional groups and specific constitutive units, which are present in the extracts. This information allows us to better understand the environmental impact of biochar on the soil ecosystem.

Stormwater management in frame of green infrastructures of cities.
Novotný, Michal ; Raček, Jakub (referee) ; Hlavínek, Petr (advisor)
The aim of the diploma thesis is to create an evaluation and recommendation of measures in the field of water management within green infrastructures of cities according to appropriate size. These measures apply to typical urban buildings managed by cities of this size. The first part of the diploma thesis deals with a research focused on the current state of stormwater management within the green infrastructure of cities. The legislative aspect is also outlined and measures and technologies for stormwater management are described. The practical part of the diploma thesis deals with a case study for the design of stormwater management within the green infrastructure of the city of Třešť. Stormwater management methods for various buildings owned by the city of Třešť are designed and economically assessed.

Ways of rain water disposal or reuse in the newly built production compound near the Hodejice village
Kabátek, Stanislav ; Menšík, Pavel (referee) ; Hyánková, Eva (advisor)
The task of this work is to solve rainwater management, which will be captured on the roof and on the paved areas due to the planned construction of the production factory in Hodějice village. Outflow of rainwater could glut culvert beneath railway line. Resolving rainwater management is a prerequisite for obtaining a building permit. The solution is a system of infiltration blocks with controlled drainage, which ensures the retention and not-increasing of the original rain outflow from the land. For solution manual calculation according to ČSN 75 9010 and the application from the ASIO manufacturer is used. The benefit of this work is the design of a system for automatic irrigation of vegetation on land and a system for eventual maintenance and washing of technical equipment. This will use the rainwater that would otherwise outflow meaningfully.

Pre-treatment of rainwater before entering the infiltration tank
Spurný, Martin ; Balas, Jan (referee) ; Hluštík, Petr (advisor)
The diploma thesis is focused on the topic of pre-treatment of rainwater before entering the infiltration tank. The theoretical part deals with the issue of rainwater, their division and pollution, as well as technical solutions for rainwater management. In the practical part, testing of selected street drains of various construction systems in the laboratory of VHO (municipal water management) was performed and subsequently these drains were evaluated according to various criteria - the amount of captured material, drain cleaning system and filter construction.

Reservoirs - Brno, Zluty kopec (Yellow hill)
Rozsypal, Petr ; Poláš, Michal (referee) ; Palaščák, Michal (advisor)
The area of water reservoirs on Žlutý kopec is a unique site of a technical herritage, which has the potential to be attractive to the general public. Its uniqueness lies not only in the interiors of individual reservoirs, but also in the large flat areas of greenery, under which the reservoirs are hidden. Due to the size and location of the area within the city, it would be irresponsible to sacrifice it only for tourism and keep it closed to the public most of the time. Since I am of the opinion that the city of Brno has more than enough underground structures sacrificed to tourism, the aim of my work is to find a way to meaningfully integrate this area into the structure of the city, so that it becomes as much a daily part of it as possible.

Technical solutions for blue-green infrastructure in cities
Císařová, Monika ; Macsek, Tomáš (referee) ; Hluštík, Petr (advisor)
The bachelor thesis deals with knowledge in the field of rainwater use in cities. Inclusion of the term blue-green infrastructure and a description of the design technical elements used for efficient rainwater management in urban areas. The practical part proposes the solution of the elements of the blue-green infrastructure on Údolní Street in the city of Brno with the requirements of the utility network administrators and the sewer network operator BVK, a.s ..

Sanitation installation and grey and rain water reuse in industry complex
Talač, Michal ; Lněníček, Ladislav (referee) ; Vrána, Jakub (advisor)
The aim of this Bachelor work is to outline a proposal for a plumbing system in the administrative premises of ESL plc, including a proposal for the usage of rainwater and greywater. Owing to the different attributes of rainwater and greywater, and the different issues surrounding them, the theoretical part is divided into two sections. In each section the attributes of the water, its quality, history and current methods of dealing with it are described. The practical part deals with proposals for domestic water supply and sewerage. The practical part includes a proposal for the location and size of storage tanks and wastewater treatment plants used for treating greywater. An essential element of this part is to equate the calculations with the subsequent design.The final section of this work is a project which includes technical drawings.
