Rainfall data in urban drainage
Mrázek, Jan ; Prax,, Petr (referee) ; Raclavský, Jaroslav (advisor)
The aim of the bachelor thesis is to process knowledge from measured precipitation data and aplicating this knowledge on methods of prepration of a hydraulic sewage network model of Znojmo city. The first part is a research in the field of interest, being sewage network and precipitation data processing. The detailed procedure of modeling and quantification of the measured data is explained in the practical part of the thesis. After that the process of inputting the data in to a hydraulic model in MIKE URBAN, the program which draws topological data from GIS (retained by VAS a.s. as the investor) and exports the final model into a SWMM enviroment. At last but not least the thesis focuses on schematization of the objects situated on the sewage network, such as relief chambers. The result is a noncalibrated and nonverified model of a part of sewage system of the Znojmo city and systematically organized measured critical rains. This model is going to be optimized after this thesis is finished, thus also calibrated and verified.

Structural and technical condition of the sewer network
Šimek, Radim ; Hluštík, Petr (referee) ; Raclavský, Jaroslav (advisor)
The bachelor thesis is focused on the evaluation of the construction and technical condition of the selected part of the sewer network. The first part of the thesis deals with the problems of designing, exploration and methodology of evaluation of sewerage system and sewer connections. In the second part of the camera records were recorded failure classification according to the coding system ČSN EN 13508-2. The individual shafts and sections of the selected section of the sewer network were evaluated by technical indicators for which the overall technical condition was evaluated. The data was processed in Microsoft Office Excel. The results found show that the selected section of the sewerage network is in critical condition and measures should be taken to address it. At the end of the thesis there are proposed basic possibilities of rehabilitation.

Alternative methods of sewer systems of municipalities
Podhrázský, Martin ; Raček, Jakub (referee) ; Raclavský, Jaroslav (advisor)
The first part of thesis focus on design of alternative sewer collection systems. Shortly is described the influence of using alternative sewers to quality of wastewater, next are described parts of pressure and vacuum sewer systems and possible ways for designing. The second part applies known for designing both pressure and vacuum sewer system in municipality Lubna, Czech Republic, and compare the cost of construction of alternative sewer systems with traditional gravity system. It is possible to reduce cost of sewer collection systems using alternative ways, mainly when in the locality are inappropriate conditions for a traditional gravity system.

Renovation of sewer network with CIPP methods
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.

Assessment of selected part of sewer network in urbanized area
Köhler, David ; Prax,, Petr (referee) ; Raclavský, Jaroslav (advisor)
The aim of the thesis is to assess the current state of sewerage of the site of interest in Ostrava and to suggest a possible renewal or extension of the sewer network. The work is divided into accompanying report, technical report, hydrotechnical calculations and drawing documentation. The assessment consists of determination of the technical state of selected sewers, hydraulic assessment of the sewer network with a proposal of possible measures and economic evaluation of these measures. In the part of hydrotechnical calculations creation of hydraulic model in program MIKE URBAN is described, including process of calibration and simulation of individual proposed variants of renewal or extension of sewer network of the locality of interest.

The study of sewerage of selected municipalities
Chromík, Radek ; Raček, Jakub (referee) ; Raclavský, Jaroslav (advisor)
The author of bachelor´s thesis addrress the issue of alternative solution sewerage selested municipalities. Resolved area for this work is Nové mlýny. The author chose the construction of a nem gravitationel sewerage systém for sewage and retained the original sewerage systém for the use of drainage of rainwater from the selected area. The aim is to recommend the technically optimal and economically most advantageous variant of the village of Nové Mlýny according to the requirements of the operator

Variants of sewerage of municipalities to 2000 inhabitants
Remešová, Terezie ; Ručka, Jan (referee) ; Raclavský, Jaroslav (advisor)
The main goal of this thesis is a proposal and a comparing potential options about drainage of village Bořetice. Proposed variants are building of a new sewer network and a pump station according to PRVK, building of a new sewer network and a sewage treatment plant and a building of a new sewer network with a finishing wastewater treatment in the stabilization tanks. This thesis also includes a summary of current options of drainage village up to 2000 inhabitants.

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.

Simulation modeling of the sewer network when applying elements for rainwater management
Vondráček, Filip ; Lžičař, Jakub (referee) ; Raclavský, Jaroslav (advisor)
The master's thesis focuses on methods of stormwater management. The introductory part of the research provides an overview of the current legislation related to this issue in the Czech Republic. Following that, there is a brief introduction to the history and stormwater management worldwide. The main section of the research acquaints the reader with methods of stormwater management in our conditions. Another part of the thesis is a technical report, describing the creation of a stormwater network model in a selected location with the application of insights into stormwater management from the research
