Holeš, Petr ; Helcelet, Marek (referee) ; Raclavský, Jaroslav (advisor)
Diploma thesis makes a summary of today’s state of CIPP methods designed for sewer relining. Thesis presents classification of CIPP methods between other NO-DIG technologies. Then CIPP methods are divided into groups according to the material used for the liner, applied resin, installation method and curing method. Designing of the CIPP liner used for sewer renovation is also part of this diploma thesis. The result of the theoretical part of this work is a table, which states suitability of particular methods for use in a sewer of specific technical properties. Practical part of bachelor’s thesis is dealing with the analysis of defects of an existing sewer in the city Přerov. Analysis was done due to the camera examination provided by the company Wombat s.r.o. Later the table developed in theoretical part was applied, and then the suitability of use of all parameters of CIPP liners was commented. At the end the plan of works is designed, with the plan for pumping of water included.

Study of sewer network of selected municipality
Remešová, Terezie ; Lžičař, Jakub (referee) ; Raclavský, Jaroslav (advisor)
The main goal of this diploma thesis is the proposal of sewerage variants of local parts of village Pačlavice, which are villages Pornice and Lhota. For individual municipalities are proposed three partially different variants, which vary mainly in the way of wastewater draining and wastewater treatment. All three variants are evaluate from an economic and technical point of view and on the basis of evaluation is propose a variant, which is in my opinion, the most suitable for these municipalities. In the villages Pornice, Lhota and Pačlavice are proposed new delivery and gravity sections, associated objects of overflow chambers with pumping stations, independent overflow chambers or separate pumping stations that complement the existing combined sewer system to ensure the drainage of wastewater to wastewater treatment plant and following treatment of this water.

Development of new grouting materials for reverse grouting of sewers
Dolák, Martin ; Dohnálek,, Pavel (referee) ; Drochytka, Rostislav (advisor)
ABSTRACT This thesis deals with the development of silicate based reverse grouts for the purpose of rehabilitation of sewers. The work also examines the possibility of substitution of basic input raw materials with secondary raw materials, meaning replacements of both filler components and binder components. As secondary raw materials, we refer to wastes from the production process which, after the necessary treatment, are used in another production. The development and experimental verification of the functionality of the developed grout was focused mainly on the use of secondary raw materials as much as possible, while maintaining or even improving its physical and mechanical properties. Based on the results of the work, it can be stated that with a 100% replacement rate of filler components in combination with 20% replacement rate of binder components, it is possible to largely maintain the properties of the material, or even optimize them. The results of the thesis also point to the possibility of reducing the economic and environmental demands of production of building materials.

Assessment of hydraulic reliability of drainage system in urban area and solution of extra-urban storm water.
Šebek, Josef ; Macsek, Tomáš (referee) ; Hlavínek, Petr (advisor)
This diploma thesis presents the topic of urban drainage systems. The first theoretical part contains methods and options for urban drainage systems, stormwater management, blue-green infrastructure (BGI) in urban areas and introduction of numerical modelling of sewerage systems. The application of modelling platforms is further described in the feasibility study in the practical part of this thesis. By using the simulation model, the study assesses the hydraulic reliability of the drainage system in the city of Jedovnice in the Czech Republic, identifies hydraulic issues and their causes on the urban drainage system. The second part of the study assesses extra-urban stormwater inflow from fields around the city caused by heavy rainfalls, which causes local flooding in the urban area. The identification as well as proposed solutions and capital expenditures, their comparison and recommendation of the optimal solution are included in the study.

Sink disposers and theirs importance in biological degradable waste removal.
Amemori, Anna ; Benešová, Libuše (advisor) ; Doležalová, Markéta (referee)
Some 30 - 50 % of municipal solid waste (MSW) is biodegradable waste. Most of this waste is sent to landfills or incinerated and is not recovered. According to Waste Management Plan of Czech Republic based on the Landfill Directive of EU, Czech Republic should to reduce weight of biodegradable waste sent to lanndfills to 75 % in 2010 and 35 % in 2020 compared with the amount that had been landfilled in 1995. In rural areas biodegradable waste is fed to animals or treated by home composting. However in urban areas the collection of separated biowaste is problem for a long time. Food waste disposers (FWDs) presents interesting alternative for the biowaste disposal. They enable the separation of food waste at source by shreding it in a kitchen sink. FWDs utilize existing infrastructure of sewer system to transport shreded wastes to wastewater treatment plants (WWTP). Wastes can be disposed in WWTPs by anaerobic digestion - the best method for disposal of food waste of animal origin. This work concentrates on literature research of studies about feasibility of FWD as a instrument for biodegradable waste removal and compares arguments for and against using of FWDs in households. Majority of studies shows no complications in sewer system and on WWTP after instalation of FWDs. Energetic and hydraulic consumption...
