Analysis of water age in the water supply network of a selected area
Pellarová, Tereza ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
The bachelor thesis deals with the issue of water age in drinking water distribution system. The theoretical part discusses the factors influencing the age of water and the quality of delivered water, and also the way in which the age influences the quality of water. Furthermore, the methods of age determination are mentioned, as well as indicators of high age. The consumption of mains water and water prices in Europe are also discussed. The practical part of the thesis focuses on the analysis of the age of water in the water supply system. The data needed for the analysis was obtained by means of the EPANET 2.2 tool, in which simulations were performed for periods with different water consumption, including the annual average, summer (July, August) and winter (January, February). After the simulation, the data were entered into MS Excel and then statistically processed and evaluated. The aim of the practical part was to find the correlations of the factors acting in the network. The age/velocity and age/flow rate were examined in the water main sections. The relations between age/consumption from the nodes and age/pressure were examined in the nodes of the network. All data were monitored within the constant age intervals occurring in the municipality´s shared water supply system.
