The subject of this diploma thesis is a study of two variants of sewer network of Cetechovice. Variant solutions include the use of existing segments supplemented by new gravitational or pressure sections. The proposed variant solutions are then economically assessed.

The thesis describes wastewater removal and subsequent handling. Also includes calculations and drawings of the proposed network and sewage treatment plant. Finally, work is designed sewerage system and wastewater treatment plant for the area. Area for which the sewerage system and wastewater treatment plant being proposed is Maleč village, which lies in Havlíčkův Brod district, north of Chotěboř. The benefit of this work is the comprehensive information on the issue of wastewater removal and subsequent purification plant. The information obtained will be used in the design of a new sewer system and wastewater treatment plant for the municipality Malec, which is currently built only rainwater drainage system and sewage is discharged into the pits and cesspools.

The present work provides a general description of the development of sewerage system in the world and in the Czech Republic. This is supplemented with the most commonly used materials and legislative links. The main objective of this thesis is to conduct a detailed description of a construction-technical survey of the sewer network city Stříbro. It contains documentation of the status quo, construction problems and defects in the sewer network in the next section, then the data obtained with the use of CCTV survey, evaluate and suggest restoring the city sewer system city Stříbro. The reason for the development is to create a recovery plan for the purpose of efficient operation of the sewer.

This work deals with factual building, which is a sewerage in the town of Rokytnice nad Rokytnou. The aim of this work is to propose measures to reduce inflow of redundant water to the local wastewater treatment plant. A method chosen to achieve it is an assesment the most problematic location and making a plan. This work includes among other outputs from the primary exploration and a condition survey, hydrological analysis and designing of two measures. These designs are complemented by the calculation of investment costs and their comparison. Appendix to this work contains drawings and the sheets from condition survey.

The diploma thesis deals with the assessment of the existing condition of the sewerage system and the proposal of measures for disposal of sewage in the village Prasklice. Submits a proposal for three options for improving the condition of the drainage and resolve the disposal of sewage. Option 1. consists in the design of new separate system and reconstruction of existing stormwater, the original combined system. To this option, including the proposal of the central sewage treatment plant. Option 2. includes the design of the pumping station for the diversion of sewage effluent to wastewater treatment plant that is proposed in the next village Pačlavice. Option 3. describes the reconstruction of the existing combined system and design of the central sewage treatment plant. The individual proposed technological solutions to the drainage and treatment of waste, is created overview of the economic performance. The object is to determine what the least economically demanding variant and show how subsidies can be used. Economically least demanding option was evaluated option 3. From an operational point of view it is most advantageous to variant 1., which will prevent future operating costs. The diploma thesis brings the village Prasklice a convenient solution for sewerage and sewage disposal in the village.

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 diploma thesis deals with sewage systems, evaluation of their technical conditions and various methods of sewage system reconstruction. First chapters provide theoretical background for sewage system reconstruction and contains general information about sewage systems and basic terminology. Next chapters describe the theoretical procedure of elaboration of proposal of existing sewage system remediation including the evaluation of technical conditions of sewage system and the evaluation of individual technical indicators. Then, individual methods of sewage system reconstruction are described. The second part of diploma thesis deals with the case study of sewage system in the village of Mikulovice. The case study is elaborated according to procedure specified in the theoretical part of diploma thesis. The case study includes the passportisation of sewage system and the evaluation of technical conditions of three selected sections. On the grounds of discovered defects, the methods of sewage system reconstruction are designed. Finally, each section of sewage system is evaluated and optimal method for its reconstruction is selected.

Diploma thesis is focused on hydraulic assessment of Lipůvka´s sewer system, done by dynamic rainfall-runoff simulation model. Because of this fact, chapter about mathematical models is included. Commonly used programs to this actions are listed as well. Next part of the thesis describes monitoring campaign, which was done in Lipůvka and results are used to calibrate the simulation model. Hydraulic assessment of sewer system by this calibrated model was done.

This work deals with the evaluation of the technological state of the sewerage network, as well as the subsequent method of remediation for each failure. The first part contains the accompanying report. This report includes information on the municipality in which the evaluation of the technical condition of the sewerage network took place. Next section includes the actual technical report which has data on the sewage network and its inspection. There are also information about the evaluation of the network‘s technical condition and viable ways of its rehabilitation. At the end of the section there are suggested possible ways of remediation for each of the detected failures. In the next chapter there are calculations for construction technical indicators and the calculation of the capacity of the sewerage network. The last section contains technical data sheet listing the faults of the individual sections and geodetic focus on manholes.

The aim of this diploma thesis is a rehabilitation study of the sewer network on Vídeňská street in the city of Brno. The first part of the thesis includes an accompanying review including basic data about the sewage gutter, including the characteristics of the affected area with a detailed description of the geological and hydrogeological rates. This is followed by a technical review, which consists of hydrotechnical calculations and overal summary of the construction-technical condition. The subject of the following part is a proposal and description of several varying solutions for the rehabilitation, including, particularly, trenchless technologies. Further on, all of the proposed variants are evaluated based on technical, economical and environmental impact. Finally, all the observations are summarized and a final recommendation for the way of solving the rehabilitation is carried out.
