Abstract
Potable and hygienically suitable water supply is important for both residential and commercial buildings. The contribution focuses on potable water hygiene and quality from the water stagnation point of view. Stagnation of water is very dangerous phenomena because it causes the change in water quality. Proper routing and arrangement of cold and hot water pipes can significantly reduce the risk of water stagnation. In the paper, the classical trunk-and-branch installation system with the hygienically more suitable alternatives are compared. The paper also provides the definition of potable water, basic factors affecting its quality and basic rules for its control.

We could define potable water as a "water intended for human consumption" [1]: 1. all water either in its original state or after treatment, intended for drinking, cooking, food preparation or other domestic purposes, regardless of its origin and whether it is supplied from a distribution network, from a tanker, or in bottles or containers; 2. all water used in any food–production undertaking for the manufacture, processing, preservation or marketing of products or substances intended for human consumption unless the competent national authorities are satisfied that the quality of the water cannot affect the wholesomeness of the foodstuff in its finished form [1]
Summary
The human body needs to receive a sufficient amount of potable water every day. It is very important to ensure the proper intake of potable water and it is even more important that the water we consume does not contain harmful contaminants and pathogens. The contribution focuses on potable water hygiene and quality from the water stagnation point of view. Proper routing and arrangement of cold and hot water pipes can significantly reduce the risk of water stagnation.
