Multi-objective condition assessment of selected parts of water distribution systems
Tauš, Miloslav ; Svoboda,, Miroslav (referee) ; Kriš,, Jozef (referee) ; Tuhovčák, Ladislav (advisor)
The topic of the thesis is multi objective condition assessment of water supply systems. The state of the art of condition assessment of water supply systems and the state of the art of multi objective optimization methods are presented within the thesis. Based on these recherches, the uniform methodology of condition assessment of water supply systems and its 7 modules was designed. The thesis deals with the selected modules to condition assessment of water pumping stations, water networks and pipe sections. The output of the methodology is the assignment of a category of the technical condition to the rated object. The proposed methodology was tested on real water facilities and proves the ability of a fair presentation of the technical condition of the object.

Assessment of minimal night-flows in the water supply systems
Zvejška, Tomáš ; Tuhovčák, Ladislav (referee) ; Ručka, Jan (advisor)
This Diploma thesis deals with minimum night flows issue. Basic findings about minimum night flows were summarized in the introductory part of thesis. Findings like the minimum night flow components, affecting parameters and used methodologies for assessment of minimal night flows. In the practical part of this thesis was this knowledge applied to real water distribution system in the municipality Hrádek u Sušice. The part of this thesis was also determinate the measurement accuracy of used water meter, which was formerly installed at the outlet in the Hrádek water tank. Measurement errors was determinate for the flow values, that are close to the real measured minimum night flow data in the water distribution system in municipality Hrádek u Sušice.

Stochastic modeling of water consumption in the water supply network
Kopecký, Josef ; Tureček,, Jan (referee) ; Ručka, Jan (advisor)
This thesis deals with stochastic water demand modellling in the water supply network. In the opening section, a research is created, where two different approaches to stochastic modelling of water consumption are presented. The practical part describes the creation of a deterministic hydraulic model and its calibration. Generated stochastic water demand patterns with a small time step of 1 minute, are then inserted into this model. Each household is assigned with a unique water demand pattern. Then a hydraulic analysis was done. A comparison of deterministic and stochastic approaches is presented at the end of the thesis. The comparison shows, that small-time step modelling does not have a big impact on the pressure ratios in the water supply network, but has a huge impact on the maximum flows and speeds occurring in links of the hydraulic model.

Study of Interconnection of Lanškroun and Letohrad Water Distribution Systems
Kubešová, Kateřina ; Bakrlík, Marek (referee) ; Kučera, Tomáš (advisor)
This diploma thesis describes study of interconnection of Letohrad and Lanškroun water distribution systems. The thesis contains an overview of legislative regulations and technical standards related to the construction, design and directional solution of water supply systems. Following that, there is the description of the current state of the affected water mains. Next part is the design of interconnection including hydraulic analysis in using Epanet 2.0 software. The study contains several variants of the solution. The economic assessment is included.

Hydraulic analysis of the Tvarožná water supply system
Trněná, Eva ; Sucháček, Tomáš (referee) ; Ručka, Jan (advisor)
This bachelor thesis deals with the hydraulic analysis of the existing water distribution system of Tvarožná village. The thesis is divided into several parts. The first part introduces the purpose of the work. The second part focuses on mathematical modeling of water distribution system, hydraulic analysis of water distribution system, describe Epanet 2.0 software that was used for modeling and review the current research on mathematical modeling of water distributions systems. The third part of the thesis analyzes in detail the studied area and describes drinking water distribution to the municipality. The fourth part describes the measuring campaign in the locality and its evaluation, which was subsequently used for the model construction. The fifth part describes the input data and the procedure for the model settings in the software Epanet 2.0. The results of the hydraulic analysis are the pressure conditions in the water distribution network, which are compared to the actual valid legislation. Also the hydraulic capacities of the fire hydrants and their location in the municipality are compared to the standard requirements.

Assessment of a selected part of the water supply network
Mrázek, Jan ; Dvořák,, Pavel (referee) ; Raclavský, Jaroslav (advisor)
The aim of this thesis is to research the field of water distribution system monitoring and modeling such system. In the next section the thesis describes a part of the water distribution system which is located in Pardubice district, specifically south of town Přelouč. With knowledge from the done research a hydraulic model will be done. This model made in EPANET interface will be calibrated and verified using data, which was acquired by the administrator of the system VAK Pardubice a.s. Afterwards new pipelines will be added to simulate the future situation accordingly to the area plans of the cencerned towns. Furthermore another aim is to simulate the requirements made towards the water distribution system in the future in case all the areas in area plan will be completely used. This will result into creation of forward looking hydraulic model which will show possible weaknesses of the water distribution system. In case of any shortcomings, according measures will be designed for future use.

Energy recuperation in water delivery system
Pavlík, Šimon ; Rudolf, Pavel (referee) ; Himr, Daniel (advisor)
The thesis deals with the use of energy potential in water supply networks and is divided into three main parts. The first part describes the characteristic elements of the water supply network and analyses the energy potential of the Nové Bránice water supply system, which was identified in the location of the pressure reducing valve. The second chapter is devoted to designing algorithm according to which a system of energy recovery - a pump in turbine mode is designed. The statistical analysis is counted as well. In this chapter, the theory of pump in turbine mode operation and the prediction theory of turbine characteristic estimation are presented. The final part of the thesis is devoted to creating a water network model in Epanet 2.2. In one day simulations the current state of the system with a pressure reducing valve is compared with the system including the proposed pump in turbine mode.
