Preparation and distribution management of potable hot water

There are a lot guidelines and regulations developed in many individual countries for the design, operation and maintenance for tap water systems to avoid the growth of bacteria Legionella. The aim of this study is to show the necessity of regulations for installations inside buildings and to enhance maintenance and operation of the system to reach high reliability hand in hand with cooperation of the competent staff. The core of the article stems from the ‘STN EN 806 Specifications for installations inside buildings conveying water for human consumption’ that have been accepted by the Slovak Republic and prepared Technical report TC 164 and our investigation of Legionella contamination of hot water in a cross-sectional survey in Kosice, the Slovak Republic. In brief we would like to emphasize demands for implementation of precautionary regulations and facility management in conditions of the Slovak Republic.
