Description
The operator of a centralized water supply system, a decentralized water supply system, a proprietary water supply system, or, if the drinking water is provided as part of a public activity, a building water supply system, shall notify the health department in writing or electronically of the following:
- The construction of the water supply system,
- the commissioning and recommissioning of the water supply system,
- the structural or operational change to parts of the water supply system carrying drinking water, if this change may have a significant impact on the quality of the drinking water,
- the transfer of ownership or the right to use the water supply system to another person, and
- the decommissioning of the water supply system or parts of the water supply system.
Service water systems (e.g. for rainwater utilization) that are installed in the household in addition to the drinking water system are also subject to notification.
Prerequisites
A water supply system is constructed, commissioned, decommissioned, structurally and constructionally altered or the ownership or right of use is transferred.
Special notes
The aim of the Drinking Water Ordinance (TrinkwV) is to ensure a high quality of water supplied to consumers in microbiological, chemical and physical terms. This is intended to protect human health from adverse effects that may result from the contamination of drinking water.
Quality assurance
The operators of water supply systems are responsible for the perfect quality of the drinking water they supply.
They must ensure this by conducting their own tests on the drinking water. The scope of testing covers microbiological, chemical and physical parameters. The tests may only be carried out by laboratories accredited for drinking water tests, which are approved after inspection by the notified body responsible in the respective federal state. In Bavaria, the Notified Body at the State Office for Health and Food Safety is responsible for this. It publishes the current list of approved drinking water testing laboratories on its website.
Independently of this, the water supply systems are officially monitored by the health authorities.
Consumer information
The Drinking Water Ordinance stipulates that consumers must be informed at least annually by the operator of the water supply system about the quality of the drinking water by means of suitable and up-to-date information material. Upon request, individual results of drinking water tests must be made available to the consumers concerned in accordance with § 21 Para. 1 Sentence 3 TrinkwV. In the case of water treatment, the duty to provide information also includes the treatment substances used. Furthermore, consumers must be informed about exceptionally permitted deviations from the specifications of the Drinking Water Ordinance or restrictions on use.
