Drinking Water Facility Registration

Anyone operating a water supply facility that provides drinking water to the public or to a commercial establishment (including private wells, small waterworks, and building-internal systems) must notify the competent health authority (Gesundheitsamt). Notification must be made at least four weeks before commissioning, and cessation of operations must be reported within three days.

Under the Drinking Water Ordinance (TrinkwV), your facility is subject to regular water quality monitoring. You must have the water tested at certified laboratories for microbiological, chemical, and physical parameters at intervals determined by the health authority, typically at least annually. The health authority conducts on-site inspections and may impose additional testing requirements based on local conditions. Fees apply for the official monitoring.
