Drinking water in 47167
For this postcode the responsible water supplier publishes several supply zones. Which of them serves an individual address is not published — below are the values of the zone with the most documented parameters, the remaining 2 underneath.
How to read the share of the parametric value
Several samples per year: for chemical parameters the mean value is given, for microbiological ones the highest measured value. There the parametric value is zero — a single finding would disappear in the average, and it is precisely that finding which is the information. Which reference applies is stated in the last column of the table.

Frequent questions about postcode 47167
- How hard is the water in Postcode 47167?
- Stadtwerke Duisburg publishes a total hardness of 1,9 mmol/l for the supply zone Versorgungsbereich 2 - Nördlich der Ruhr ohne Homberg und Baerl (Ruhrort nur nördlich Vinckekanal) — that corresponds to 10.7 °dH. The hardness range is a classification under the German Detergents and Cleaning Products Act (soft below 8,4 °dH, medium 8,4 to 14 °dH, hard above that) and not a quality verdict — it indicates how much calcium and magnesium is dissolved in the water. Basis: Publication by the water supplier, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 47167?
- Stadtwerke Duisburg publishes a nitrate value of 11 mg/l for the supply zone Versorgungsbereich 2 - Nördlich der Ruhr ohne Homberg und Baerl (Ruhrort nur nördlich Vinckekanal). The statutory parametric value is 50 mg/l; the measured value represents 22 % of the parametric value. Basis: Publication by the water supplier, retrieved on 11/07/2026.
- Are PFAS detectable in the drinking water in Postcode 47167?
- Stadtwerke Duisburg publishes for the supply zone Versorgungsbereich 2 - Nördlich der Ruhr ohne Homberg und Baerl (Ruhrort nur nördlich Vinckekanal) a sum value PFAS-20 of 14 ng/l (0.014 µg/l). The statutory parametric value is 0.1 µg/l; the measured value represents 14 % of the parametric value. For the sum of the 20 individual substances, this parametric value has applied since 12/01/2026. Basis: Publication by the water supplier, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 47167?
- Stadtwerke Duisburg. The values shown here come from the supply zone Versorgungsbereich 2 - Nördlich der Ruhr ohne Homberg und Baerl (Ruhrort nur nördlich Vinckekanal) and apply to the water the supplier delivers. What happens between the building connection and the tap — in old lead pipes, for example — is not covered by these analyses; information on that is provided by owners, the health authority or an examination by an accredited laboratory.
