In diploma assignment we present the development process of a mechatronic system for the transport of drinking water from conceptualization to realization. The system enables us to fill and empty the reservoir with capacity of 3000 l within the time period of 180s. We use cable car for water transport between lower and upper cable station with 963 m of height difference. In the phase of the conceptualization we see different concepts and their evaluation. Optimizing and dimensioning of the chosen concept was carried out with the use of numerical analisys. There is also detailed presentation of manufacturing processes of different components and results of the working system.
