Drinking Water Ordinance: Important Knowledge for Property Owners and Managers

Welcome to the Hochheiden Property Management blog, your specialist in real estate management. Today, we dedicate ourselves to a topic of utmost importance for all property owners and managers: the Drinking Water Ordinance. This ordinance ensures that the drinking water in residential buildings is not only clean and safe but also healthily unobjectionable. In this post, you will learn what the Drinking Water Ordinance entails, what obligations it imposes on owners and managers, and how you can ensure that your properties meet the requirements.

What is the Drinking Water Ordinance?

Die Trinkwasserverordnung (TrinkwV) is a German law that regulates the quality of drinking water. It transposes EU directives and specifies the requirements for the quality of drinking water to protect consumers' health. This includes limits for microorganisms, chemical substances, and other parameters that must be regularly monitored.

Duties arising from the Drinking Water Ordinance

Für Eigentümer und Verwalter von Mehrfamilienhäusern ergeben sich aus der Trinkwasserverordnung verschiedene Pflichten:

  • Regular Inspections: The drinking water installations must be regularly tested for Legionella and other harmful substances. The frequency of these tests depends on the type of usage and the size of the facility.

  • Documentation and Reporting: The results of water tests must be documented, and if the limits are exceeded, they must be reported to the health authorities.

  • Information Obligation: Tenants and users of the property must be informed about the quality of the drinking water and any potential risks.

Implementation of the Drinking Water Ordinance

To meet the requirements of the Drinking Water Ordinance, owners and managers should consider the following steps:

  1. Commissioning an accredited laboratory: For water testing, a laboratory accredited according to DIN EN ISO/IEC 17025 should be commissioned.

  2. Regular maintenance: The drinking water installations should be regularly maintained to prevent deposits and contamination.

  3. Adaptation of the installations: In case of repeated exceedances of limit values, the drinking water installations must be inspected and, if necessary, renovated or adapted.

  4. Education and information: It is important to educate all residents and users about the importance of responsible handling of drinking water.

Compliance with the Drinking Water Ordinance is not only a legal obligation but also a contribution to the health protection of residents. Violations of the ordinance can lead to serious health risks and have legal as well as financial consequences.
