Assessment of drinking water consumption in the water supply network of the Valašské Meziříčí
Fučík, David ; Libosvár, Dušan (referee) ; Ručka, Jan (advisor)
This diploma thesis deals with the analysis of the time series of drains from the water reservoir and evaluation of the minimum night flow in the water supply network of the town of Valašské Meziříčí. In the theoretical part of this thesis were elaborated research of Czech and foreign literature focusing on drinking water consumption analysis, measurement and evaluation of minimum night flow and methods of determination of water losses in distribution systems. The practical part includes analysis of water outflows from reservoirs, evaluation of minimum night flow and determination of basic water loss indicators for selected district metered areas of the network. The above-mentioned water supply network is operated by the Vak Vsetín, a.s.

Smart Metering of Water Supply System at Campus of Faculty of Civil Engineering BUT
Černíková, Eva ; Ručka, Jan (referee) ; Tuhovčák, Ladislav (advisor)
The aim of this thesis is to perform an analysis of possibilities and benefits of installing the Smart Water Metering technology at campus of Faculty of Civil Engineering, Brno University of Technology. The main goal was to provide specific solutions of Smart Metering systems from different companies. One part of this thesis is dedicated to a detailed analysis of a water consumption measurement campaign that took place at the beginning of this academic year using dataloggers. Real-time flow rate and consumed volume was recorded every five minutes. Therefore it was possible to determine water consumption patterns during the day and also tell the minimum, maximum and average flow rate in different parts of the campus. Thanks to these measurements, irregular water consumption during the night was observed. This would not have been easily detected without recording real-time data. This system of recording real-time flow rates with dataloggers is considered to be suitable for the needs of faculty. Thanks to a GSM module, recorded values are sent to an FTP server once a day. From there the data can be downloaded to any kind of analysis software. Installation of Smart Water Metering technology at campus of Faculty of Civil Engineering would be beneficial for both operation of the water supply network and also for purposes of an academic research.

Hydraulic analysis of the Hnojník water supply system
Nováková, Jana ; Tureček,, Jan (referee) ; Ručka, Jan (advisor)
This Bachelor thesis is focused on hydraulic analysis of Hnojnik water supply system. The structure of this thesis is devided into several parts. The first part focuses on general hydraulic analysis, possibilities of using matematic modeling, and types of analysis that can be performed in a water network. Next section contains a list and brief characteristics of software tools used for hydraulic analysis. Attention is focused on the EPANET 2.0 which was used to build a model of Hnojnik water supply system. The last section describes the construction of the network model, input data used for modeling and evaluation od hydraulic analysis.

Drinking water customer complaints analysis
Trněná, Eva ; Baran, Přemysl (referee) ; Ručka, Jan (advisor)
The diploma thesis deals with the analysis of complaints from drinking water customers, particullary about water quality. Within the theoretical part, it presents both the view of the customer of the drinking water and the view of the operator of the water supply system. It also presents possible ways to use drinking water customers complaints as indicators of water system service quality. Further, the thesis focuses on the satisfaction of customers and their trust in the operators of water supply systems. An analysis of complaints of drinking water users on the quality of water that has been received by the operator during the last five years has been performed as part of the case study in the practical part of the thesis. The cases are interpreted in context of the conditions at the given site of the water supply network.

Properties of fine sediments in the water supply network
Dukát, Petr ; Sucháček, Tomáš (referee) ; Ručka, Jan (advisor)
This bachelor’s thesis deals with properties of fine sediments which occur naturally in water supply pipes. With focus on issues of fine sediments samples literature search was made and measurement methodology, which enables better understanding the behavior of sediment in the water supply network, was determined. During controlled pipes flushing, samples of fine sediments were taken from selected water pipes sections and under laboratory conditions sedimentation test, using measurement methodology, was made. Sedimentation test included the measurement of turbidity for the time necessary to meet the limit value of turibidity given by the government regulation for drinking water. Results of this thesis are important input information for simulating the spread of high turbid water in the water supply network during a turbidity event.

Drainage of sewage from expanding housing development
Studený, Martin ; Kejvalová, Eva (referee) ; Ručka, Jan (advisor)
This bachelor thesis deals with the technical-economical study, which compares the investment, operating and total costs of the given variants of drainage in the expanding development with regard to the variable number of considered real estate in the development. The theoretical part deals with variants of the technical solution of the case study. In the practical part of the thesis a technical-economic study is conducted, where the individual variants are elaborated in terms of investment, operating and total costs of the variable number of considered real estates in the development and their mutual comparison with respect to property law relations.

Time series analysis of the waste water flow in the pressure sewer
Ambrož, Martin ; Beránek, Josef (referee) ; Ručka, Jan (advisor)
This Bachelor Work is describing the time series analysis of outlet from pressure waste water sewerage and detailed statistic data evaluation in village Štěpánovice. In terms of this Work there were realized detailed evaluation of measured time series of flow by 5 minutes in 4 calendar months. Data evaluation was realized by software programme STATISTICA and MS EXCEL with output to determination of an average and maximal daily flow, maximal and minimal hourly flow and coefficient of non-uniformity. At the same time there was found out with statistic probability number of simultaneous running pumps of pressure sewerage of Štěpánovice village.

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.

Pressure optimisation in the water-supply system of the Střelná village
Sucháček, Tomáš ; Valkovič,, Pavel (referee) ; Ručka, Jan (advisor)
This document aims on aplication of sophisticated software programs to accomplish hydraulic analysis of real water supply, design and optimization measures for improvement of pressure conditions in water network. In this work is stated a list and description of software enabling to accomplish static or longterm hydraulic analysis of water supply when the most world used program EPANET 2.0 is described more deeply. There is described working of a EPANET and his algorithm also there are explain principles on which EPANET is based. During the hydraulic analysis of real system was used sophisticated software EPANET 2.0. With this program was processed hydraulic analysis of chosen water supply system of small consumption area. Based on the results of analysis pressure conditions has been designed and optimized measure to improve pressure conditions in the water network.
