The topic of this thesis is to create a study of the rehabilitation of the sewer network. The sewer system under assessment is located in city Znojmo, specifically Znojmo – city. In this case, rehabilitation is proposed in order to improve the functional operational properties of the sewer network and extend its service life. The work was divided into two basic parts, namely the Accompanying and Summary Technical Report. Three variants of solution were proposed. The first two variants are made as trenchless using a sanitation sleeve in the first one and a short sanitation sleeve in combination with a sanitation sleeve in the second. The third variant is made as an open excavation recovery. A description of the rehabilitation technology was carried out and the facts that each individual Option or what the three Option would bring up were defined. These three variants of the solution are assessed in terms of economic, technical and environmental impact.

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.
Assessment of the technical condition of the sewer system in the village
Krulová, Martina ; Úterský, Michal (referee) ; Hluštík, Petr (advisor)
This bachelor thesis deals with the assessment of the technical condition of the sewer network in Sudice and the subsequent recommendation of the remediation of sewerage pipes and manhole. In this work there is a legislation that deals with the issue and general information about the village. There is a description of the execution passportization of the sewer network, the passportization target and the current status of the sewer network. In the thesis is devoted a part of hydraulic assessment of sewerage network, where are calculations of sewage flows and rainwater flows in the network and consequent comparison of suggestion flow with the capacity flow. Based on the results of the performed passportization and acquired camera records, the technical condition of the sewer pipes and manholes was evaluated. The work deals with the recommendation of rehabilitation of sewerage pipes and manholes, where the most serious types of failures on the assessed sewer network are found. There are advantages and disadvantages of recommended remediation methods. The thesis includes three drawings (total situation, detailed situation and hydrotechnical situation) and a sample revision sheet.
Evaluation of the construction-technical state of the sewer network
Bártík, Tomáš ; Malaník,, Stanislav (referee) ; Raclavský, Jaroslav (advisor)
The bachelor thesis is focused on the evaluation of the structural and technical condition of the selected part of the sewer network. The work is devided into two parts. The aim of the first part is the issue of designing, exploration and methodology of evaluating of sewer networks and sewer connections. In the second part of the camera records, there was carried out the classification of disorders according to the coding system ČSN EN 13508-2. Each section was subsequently rated by the technical indicators, which were evaluated for overal technical condition. The assessment has shown that one of the sections is in critical condition. It should address the measures to improve the condition of this section. For this reason, there are designed two kinds of rehabilitation.
