Drinking water in 14797
For this postcode Wasser- und Abwasserzweckverband Werder-Havelland (WAZV) 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 11 underneath. The water supplier publishes 1 further local networks that cannot be clearly assigned to this postcode — they are listed on the water supplier page.
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.

Wasser- und Abwasserzweckverband Werder-Havelland (WAZV)Assigned 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 16/04/2024. 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 |

These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 02/05/2023. 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.

Frequent questions about postcode 14797
- How hard is the water in Postcode 14797?
- Wasser- und Abwasserzweckverband Werder-Havelland (WAZV) publishes a total hardness of 3,5 mmol/l for the supply zone Netzproben WAZV Werder-Havelland - Ferch, Potsdamer Platz 9, Amt Schwielowsee — that corresponds to 19.6 °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: 29.04.2024, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 14797?
- Wasser- und Abwasserzweckverband Werder-Havelland (WAZV) publishes a nitrate value of <0,00300 (NWG) mol/m³ for the supply zone Netzproben WAZV Werder-Havelland - Ferch, Potsdamer Platz 9, Amt Schwielowsee. The statutory parametric value is 50 mg/l; the measured value lies below it and cannot be specified more precisely below the limit of quantification. Basis: 29.04.2024, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 14797?
- Wasser- und Abwasserzweckverband Werder-Havelland (WAZV). The values shown here come from the supply zone Netzproben WAZV Werder-Havelland - Ferch, Potsdamer Platz 9, Amt Schwielowsee 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.
