Methods of remediation of concrete sewers
Vondráček, Filip ; Úterský, Michal (referee) ; Hluštík, Petr (advisor)
The bachelor's thesis is focused on getting familiar with the methods of remediation of concrete sewers, including shafts by trenchless technology. The first part was focused on materials, shafts, methods of cleaning and methods of determining the construction and technical condition of the sewerage system. In the second and third part, the methods of remediation of concrete sewer by trenchless technology were analyzed. The fourth part talks about the remediation of shafts using trenchless technology. In the fifth part, the knowledge from the previous parts is applied to a specific section of the sewerage system and a solution for the remediation of this section will be proposed.

Methodologies for evaluating the technical condition of sewer networks
Palkovská, Vendula ; Singrová, Veronika (referee) ; Hluštík, Petr (advisor)
The bachelor’s thesis deals with methodologies for evaluating the construction and technical condition of sewer networks. The work consists of two parts. The first theoretical part is focused on the description of basic concepts related to the sewer network, acquaintance with the issues of cleaning, research and faults of sewer networks and also contains methodologies for evaluating the technical condition of sewer networks used in our country and abroad. In the second practical part, based on a camera inspection of a selected section of the sewer network, the classification of faults and evaluation according to three methodologies and their subsequent comparison were performed.

Rehabilitation of sewer networks and sewer connections
Brychta, Kryštof ; Lžičař, Jakub (referee) ; Raclavský, Jaroslav (advisor)
This bachelor thesis is about approaching the possibility of rehabilitation of the sewer network and sewer connections. The bachelor thesis is divided into two parts. The first part describes the basic division of the most used methods for rehabilitation, repair and renovation of sewer network. In the second part, the acquired knowledge is applied to the rehabilitation of a part of the sewer network in Znojmo, Rumunská - Slovenská street. Two methods of rehabilitation (CIPP lining, open excavation) were selected for the site. An economic comparison was made for these methods.

Assessment of the technical condition of the sewer network in the village
Shamko, Viktoryia ; Úterský, Michal (referee) ; Hluštík, Petr (advisor)
The bachelor's thesis deals with the assessment of the construction and technical condition of the sewer network in a selected village. The research part is focused on maintenance, types and frequency of failures and inspection techniques to control the condition of the sewer network and propose reconstruction. The works include czech and foreign methodologies for evaluating the condition of the sewer network. In the practical part, a camera inspection of selected sections of the sewer network was performed, followed by a defect coding and evaluation according to two methodologies. Conforming to the assessment of the condition of individual sewer sections and manholes, rehabilitation was proposed.

Construction and technical condition of the sewer network
Petrová, Diana ; Malaník,, Stanislav (referee) ; Raclavský, Jaroslav (advisor)
This bachelor's thesis deals with assessing construction and technical condition of a selected section of the sewer system in Znojmo. The first part of the thesis deals with the issue of surveys, cleaning, sewage watertightness tests and a description of methodologies for evaluating the construction and technical condition. In the second part of the thesis classification of occurring failures from camera records is compiled according to coding system from ČSN EN 13508-2. Subsequently, the sections were evaluated according to the two methodologies, first according to TNV 75 6905 (design) and then according to the German standard ATV-M 149. Based on the results, an overall evaluation of the construction and technical condition of the sections was performed and a possible remediation was proposed. The thesis includes individual annexes classification of failures according to ČSN EN 13508 2, evaluation of construction and technical status according to TNV 75 6905 (design) and according to ATV-M 149, three drawings (situation of current state, situation of evaluation of construction and technical condition according to methodology TNV 75 6905 and according to ATV-M 149).

Measurement and evaluation of flows in sewer networks
Haška, Aleš ; Prax,, Petr (referee) ; Raclavský, Jaroslav (advisor)
Measuring flow rate, water surface and rainfall are the crucial inputs for the calibration of the hydraulic model. This bachelor’s thesis presents mathematical models and measuring devices for the sewer networks. This thesis summarises the measuring devices that are currently available and used on the sewer network. Furthermore, theory of random and systematic errors is discussed. In the second section, this theory is implemented in the chosen area for the sewer network in Znojmo. On the 9. 9. 2020, three ultrasonic measuring devices (type ISCO 2150 with AV sensor) and one device for measuring water surface (type IJINUS) were installed in this area. This thesis provides continuous measurements which are then applied for the calibration of the hydraulic model. On completion of this thesis it is necessary to continue to calibrate and verify the model in order to increase accuracy and be more precise.

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.

Assessment of a selected sewer system in an urbanized catchment area
Bártík, Tomáš ; Malaník,, Stanislav (referee) ; Raclavský, Jaroslav (advisor)
The aim of the diploma thesis is to asses the current state of a selected part of the sewer network in Znojmo, design of possible remediation and theoretical design of retention tank. The work is devided into an accompanying report, technical report, hydraulics and drawing documentation. The assesment consist of the determination structural and technical condition of selected parts of the sewer network with a proposal for remediation and economic evaluation. The hydraulic part describes the hydraulic model in program SWMM, there are processed here hydraulic calculation and there are 4 different variants of the design of retention tanks.

Assessment of technical condition of sewer system in the village
Chotová, Tereza ; Úterský, Michal (referee) ; Hluštík, Petr (advisor)
The bachelor´s thesis deals with the assessment of the technical condition of sewer network in Dub nad Moravou. Main goal of the thesis was to accomplish the passportization of the sewer network. Based on the passportization, a hydrotechnical assessment of the combined sewer network is performed. Also with a camera records provided by Podlas s.r.o. company, the technical condition of the stormwater sewer network in Bolelouc is evaluated. The rehabilitation of unsatisfactory sewerage pipes is designed by two methods. The indicative prices, advantages and disadvantages of the recommended methods are involved. The bachelor´s thesis includes four drawings, namely total situation of the sewer network, detailed situation of the combined sewer network, hydrotechnical situation of the combined sewer network and longitudinal profile.
