Drinking water in Rosenberg
There are 2 places with this name — listed below by area. To determine the exact match, look up the postcode.
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.

WW Schweighausen/Kregelberg
NOW Zweckverband Wasserversorgung NordostwürttembergAssigned 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.

Frequently asked questions about drinking water in Rosenberg
- How hard is the water in Rosenberg?
- Zweckverband Bodensee-Wasserversorgung publishes the hardness range mittel for the supply zone Wasserwerk Sipplinger Berg. 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 08/07/2026.
- How much nitrate is in the drinking water in Rosenberg?
- Zweckverband Bodensee-Wasserversorgung publishes a nitrate value of 4,0 mg/L for the supply zone Wasserwerk Sipplinger Berg. The statutory parametric value is 50 mg/l; the measured value represents 8 % of the parametric value. Basis: Publication by the water supplier, retrieved on 08/07/2026.
- Who supplies the drinking water in Rosenberg?
- Zweckverband Bodensee-Wasserversorgung. The values shown here come from the supply zone Wasserwerk Sipplinger Berg 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.
General questions — how current the data is, limit of quantification, parametric values, who is behind this site — are answered under Questions & answers.
