Drinking water in 71364
One supply zone, water supplier: Stadtwerke Winnenden GmbH.
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.

Stadtwerke Winnenden GmbHAssigned via the water supplier — the exact supply zone boundary within the postcode is not yet linked.
These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 31/12/2024. We have no newer values — which is why we show the latest available ones rather than none at all. They say nothing about how the water has changed since then.
| Parameter | Value | Parametric value | Share of the parametric value | Reference |
|---|---|---|---|---|
| Nitrate | 20,9 mg/L | 50 mg/l | 42 % | Single value |
| Lead | <0,001 mg/L below limit of quantification | 10 µg/l | < 10 % * | Single value |
| Sulphate | 23,9 mg/L | 250 mg/l | 10 % | Single value |
| Sodium | 10,3 mg/L | 200 mg/l | 5 % | Single value |
* Value below the limit of quantification: the actual share of the parametric value is not known; it lies somewhere below the stated upper bound. The marker shows where the limit of quantification of the measurement lies relative to the parametric value.

Frequent questions about postcode 71364
- How hard is the water in Postcode 71364?
- Stadtwerke Winnenden GmbH publishes a total hardness of 13.3 °dH for the supply zone HB Schelmenholz (hardness range medium). 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: Juni 2024, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 71364?
- Stadtwerke Winnenden GmbH publishes a nitrate value of 20,9 mg/L for the supply zone HB Schelmenholz. The statutory parametric value is 50 mg/l; the measured value represents 42 % of the parametric value. Basis: Juni 2024, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 71364?
- Stadtwerke Winnenden GmbH. The values shown here come from the supply zone HB Schelmenholz 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.
