Postizanje i održavanje higijenskih uvjeta u instalacijama pitke vode
In this paper satisfactory hygiene conditions for the water supply system are proposed through guidances, specifications and recommendations. In addition to hygienic design of water installations, the thesis provides possibilities for maintaining hygiene. Additionally, impacts on water quality are discussed and microorganisms that can proliferate due to these impacts are described. 
Installation solutions were implemented using the example of an actual object in Dendrit computer program. A pressure drop calculation was performed. The system analysis obtained satisfactory water temperatures, corresponding flow rates, an overview of the system materials and the time required to reach the required water temperature at the point-of-use fittings. A thermal simulation was performed to check temperature drop in the recirculation part of water system.
