Drinking water in 48599
For this postcode Stadtwerke Gronau GmbH 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 1 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 48599
- How hard is the water in Postcode 48599?
- Stadtwerke Gronau GmbH publishes a total hardness of 18 °dH for the supply zone Wasserwerk Epe (hardness range hart). 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: Oktober 2025, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 48599?
- Stadtwerke Gronau GmbH publishes a nitrate value of 16 mg/l for the supply zone Wasserwerk Epe. The statutory parametric value is 50 mg/l; the measured value represents 32 % of the parametric value. Basis: Oktober 2025, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 48599?
- Stadtwerke Gronau GmbH. The values shown here come from the supply zone Wasserwerk Epe 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.
