At the handover of a system, the operator should be made aware that, from that point onwards, (s)he is responsible for regular and complete exchange of drinking water and for operation of the system as it is intended, at all extraction points. In some countries, disregarding the relevant ordinances constitutes a criminal offence.

For buildings, whose usage requires increased hygiene measures (e.g. food processing premises, hospitals, care homes), a hygiene plan is agreed by the operator, a hygienist, the relevant health authorities and, if applicable, the water supplier. The hygiene plan of the drinking water installation must be compiled for the specific use and system and must contain details of the intended use of the drinking water installation. It is recommended that a maintenance contract for the drinking water installation is concluded with a specialist company or that the measures are carried out by one’s own specially trained specialists.


Drinking Water safely under control with Viega System Solutions


Water quality controls for public buildings are mandatory. Therefore, water must be regularly chemically and microbiologically tested at extraction points in public buildings. So that these samples can be extracted under laboratory conditions, without contamination of the parameter via external influences, Viega has developed the two-part and, subsequently, cost-effective Easytop sample extraction valve. It consists of a permanently secured zero stagnation space extraction valve and an, especially for the extraction process attached, actuator which can be sterilised. All of the parts which come into contact with water are made of gunmetal and can therefore be treated in autoclave temperatures or flame treated.
