The aim of my thesis is to design the water supply of the 2nd pressure zone of the village Veličná. The work consists of two parts: text and graphic. The text part describes the current state of water supply to the village and a description of the proposed solution for supplying the 2nd pressure zone with water. The supply proposal for the 2nd pressure zone includes an extension of the water supply network on the basis of the envisaged land-use plan and a proposal for accumulating for the 2nd pressure zone. The graphical part of the thesis includes a hydraulic assessment of the design of the extended water supply network in the 2nd pressure zone and the design of the supply of the 2nd pressure zone shown by situation of water supply and profiles.
