[Significance of the ordinance on the quality of water for human consumption (Drinking Water Ordinance 2001) for hospital hygiene].
Since January 2003, the new German Drinking Water Ordinance (DWO) has become operative. This paper briefly reviews some major consequences for hospitals. One of the main topics is the increased responsibility of operators of drinking water installation systems in hospitals concerning both the maintenance and control of good drinking water quality. Besides harmful chemical parameters, proliferation of pathogens can occur such as Pseudomonas aeruginosa, Legionella spec., Acinetobacter, and others which are mainly bound to biofilms and thus less affected by disinfectants. Recent epidemiological investigations point out that the relevance of waterborne pathogens is still considerably underestimated, particularly in hospitals. Local public health authorities play a central role in clinic inspection, supervision of water installations, surveillance, and risk assessment in cases of noncompliance with DWO requirements. For this reason, every irregularity detected must be reported to the local public health authority.
