Drinking water hygiene in buildings

Hygiene has a particularly high priority in sensitive buildings such as homes for the elderly and clinics or larger buildings, such as hotels, starting with the installation and going on to everyday operation.

Building types

In sensitive buildings, such as hospitals and homes for the elderly, as well as larger buildings such as hotels, special attention must be paid to drinking water hygiene.

Homes for the elderly

For the protection of persons with a weak immune system

Hygiene has a very high priority in homes for the elderly, as older and often persons with a weak immune system are staying there. Accordingly, the cleanliness of the drinking water is of central importance. Operators of homes for the elderly are well advised to pay particular attention to hygiene in the drinking water installation so as to exclude any health risks for the inhabitants as far as possible.


Impeccable drinking water free of pathogens

Not in all hotels can all the individual rooms and the associated water connections be used. Particularly when the rooms are occasionally empty, it is advisable to pay attention to hygiene in the drinking water installations and to check these regularly. The highest quality of drinking water is important, as in hotels there are many people with differing levels of health stability - an important point to consider for operators, so that all guests feel comfortable.


For the protection of persons with a weak immune system

Hospital hygiene must meet the highest requirements. Hygiene in the water supply is an important component. Drinking water is used everywhere. Starting with hand washing before operations, cleaning of surgical instruments and hospital equipment, in the catering sector, for hospital cleaning and laundry.

Without hygienically perfect water this is not possible. Behavioural rules in hospitals help to combat the spread of infections. Our hygienic concept provides efficient protection against contamination in the pipeline system, a lasting protection against infection and helps to prevent nosocomial infections.


One of the main priorities for achieving optimal drinking water hygiene is the operation of the the system, which includes the installation, command and control.

Hycleen - Operation

Even during transportation and storage of the drinking water installation components, contamination must be avoided. After the installation of the drinking water system a dry leak test is recommended. This prevents standing water from contaminating the pipeline system before the system is put into use.

Installation and assembly

Schon beim Transport und der Lagerung der Bestandteile einer Trinkwasserinstallation müssen Verunreinigungen vermieden werden. Nach dem Einbau der Trinkwasseranlage empfiehlt sich eine trockene Dichtheitsprüfung. So wird verhindert, dass stehendes Wasser bis zur Inbetriebnahme das Rohrleitungssystem kontaminiert.

Hot water distribution

Hot water preparation and distribution

Microorganisms love temperatures between 25 °C and 50 °C. They multiply most in this temperature range. Therefore, the temperature in the water heater should never drop below 50 °C. As the water standing in hot water pipes cools slowly, care must be taken, among other things, to ensure that the circulating water pump is functioning properly and that the installation is as evenly distributed with hot circulating water. If the volume of the water heater is exchanged once a day, stagnation times in the critical temperature range can be significantly shortened.

Unused sections

Unused section regions form true nutrient soils for germs and microorganisms. The drinking water installation must therefore be regularly checked for pipeline sections or dispensing points that are rarely or never used. If dispensing points are no longer used, they should be dismantled together with the connecting pipe. Rarely used conduction areas are to be flushed frequently.

Cleaning and flushing

In order to prevent the formation of germs, drainage areas in hot water pipes, in which the water cools slowly below 50 °C., must be flushed regularly. The same applies to unused pipe sections in cold water pipes. In these sections, especially when the insulation is insufficient, standing water slowly heats up to a growth-promoting level. Installations with backwash devices should be flushed every three days. Salt containers, perlators and household water meters require regular cleaning and disinfection.
