Methodology of use greywater in the selected objects
Raček, Jakub ; Pollert,, Jaroslav (referee) ; Stanko,, Štefan (referee) ; Raclavský, Jaroslav (advisor)
The concept of reusing wastewater in buildings has recently become more important. This is due to change in climatic conditions and reduction of the yield of water resources. Greywater can broadly be defined as not extremely polluted wastewater coming from basins, showers, baths, kitchen sinks and washing machines. The concept based on the use of alternative rate sources wouldn't need same strict parameters as drinking water. Dissertation engage in collecting greywater from basins, showers and wash machines separately from the other more polluted domestic wastewater at the dorms, the laundry machines, the hotels, detached houses, the swimming pools, the office buildings and other buildings. The research showed that membrane filtration meets all needed parameters of water quality and can be used in house systems where we use cleansed white water to flush toilets, watering garden or grass areas. There is still a lack of experience and documentation for such system of operation in our country. Systems of use of greywater in selected objects are detaily solved in my dissertation directed at system proposal.

Utilization of the greywater
Zríni, Miroslav ; Soukup, Lubomír (referee) ; Štigler, Jaroslav (advisor)
The bachelor work consists of two parts. First is the theoretical research about waste water of household. Due to the different features of the water, it is divided into greywater and rainwater. In each section are mentioned properties, quality needs, cleaning method and others. Concrete utilization of these waters is illustrated on the recycling system by company Asio. s.r.o. Last chapter deals with heat recovery of the greywater. Second, the practical part is aimed at proposal of a small recycling unit in certain location. It includes proposal of a storage tank, selection of a pump device or water station and any necessary accessories. The end is concluded with financial balance-sheet of the project.

Proposal for the use of gray water in the swimming area "Kraví hora" with a view to completion of the wellness center
Běloušková, Pavla ; Plotěný, Karel (referee) ; Biela, Renata (advisor)
Greywater is the leftover water from baths, showers, hand basins and washing machines only, what implies that it is free of faeces and urine. Greywater can be recycled as processing water (whitewater) for toilet and/or urinal flushing or landscape irrigation. Energy recovery from greywater looks also very promising. The subject of this thesis is short research on the issue of the use of greywater in the first part, the following chapter provides examples of the use of greywater in practice. Practical part of thesis provides suggestion of use of greywater and their heat potential in swimming area Kraví hora with regard to completion of wellness centre. This part also includes economical analysis of suggested recycling.

Plumbing Systems with Low Water and Energy Consumption
Nikrmajer, Vojtěch ; Vrána, Jakub (referee) ; Bárta, Ladislav (advisor)
The thesis deals with energy-saving plumbing systems. It is divided into three parts: task analysis, applications theme on the building and experiment. In the first part are described the possibilities of saving water and energy in the plumbing systems. The second part contains a comparison of some variants of saving solution water supply system and sanitary drainage system at the hotel. Part of the experiment investigates the water consumption for washing hands in addiction: the pressure in the water supply system and the type of mixing valves.

Possibilities of using gray waters
Bogáňová, Ida Antonie ; Raclavský,, Jaroslav (referee) ; Biela, Renata (advisor)
Greywater is waste water from washbasins, showers, baths, kitchen sinks, dishwashers and washing machines. This can be treated to gain so-called white water, which can for example be used for flushing toilets and urinals, watering greenery or for cleaning. The subject of this diploma thesis is to state the possibilities for utilisation of greywater. In the first part of this thesis, research will be elaborated on the given topic. In the following chapters, I would like to state examples of the possibilities for utilisation of greywater. The practical part should consist of design of a system for treatment of greywater in a specific building.

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.
