Price elasticity of household water demand in Czech Republic
Hortová, Jana ; Krištoufek, Ladislav (advisor) ; Šopov, Boril (referee)
Během posledních desetiletí se v eské republice stále zvyšují ceny vody, což vede k následnému snižování její spotřeby. Tomuto tématu se věnuje velké množství studií, ale dle našich zjištění se žádná z nich nezabývá eskou republikou. Obecně lze říci, že hlavním cílem této práce je nalezení krátkodobé a dlouhodobé cenové elasticity poptávky po vodě v eské republice a následně v Kladně. Při zkoumání poptávky po vodě v Kladně vyšetřujeme cenovou elasticitu v závislosti na odlišném počtu člen· v domácnostech. V obou případech dojdeme k závěru, že poptávka je neelastická v krátkém i dlouhém časovém období. Dále zjistíme, že cenová elasticita roste s klesajícím počtem člen· domácností v obou časových obdobích. Naše výsledky jsou v souladu se závěry ostatních studií.

Management of gray water and rain water
Kocourková, Michaela ; Synáčková, Marcela (advisor) ; Renata, Renata (referee)
Evolution and advancements of human activity is unstoppable, still we should not forget about basic natural processes which proceed no matter how man can influence them. Water is one of the main constructors of life and is necessary for function of everything live on the planet Earth. It often is categorized among the inexhaustible resources, still there lacks enough drinkable water. It is consumption grows in recent years with fast development of cities.
It is the most important part of life on Earth and with urbanization and anthropogenic interference water is negatively affected and thus it is processes in nature. Interfering with water cycle makes for higher occurrences of droughts and floods, the quality of water streams suffers. Urban areas lack the surface where water could soak into the subsoil and underground water resources shrink. Through all these influences with which we affect natural water cycles the need for water and its consumption grows in our societies. For effective use of water comes up the idea of using not only the drinkable water but waste water and other types as well. Sources can be various, rain water, reused water.
The focal point of this thesis is to be the impetus of discussion concerning the use of rain water and directly cleaning and reusing the water which comes straight from our homes. Rain water fills up underground water resources and also could be used in place of potable water. Substituting the potable water in activities and industries where such a high quality water is not needed and could be easily replaced with grey water. Grey water, being the waste water that comes from our bathrooms, is easily cleaned and can be used for various necessities. Current state where the potable water is used in absolute majority of human life appears to be extremely wasteful and unecological. Use of grey water and rain water is a possibility of ecological and thrifty water management which could prevent environmental damages and save water resources for the next generations.

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.
