For this postcode Zweckverband Sulmwasserversorgungsgruppe / Gemeinde Obersulm (geliefert durch Zweckverband Wasserversorgung Nordostwürttemberg NOW) 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 74182
- How hard is the water in Postcode 74182?
- Zweckverband Sulmwasserversorgungsgruppe / Gemeinde Obersulm (geliefert durch Zweckverband Wasserversorgung Nordostwürttemberg NOW) publishes a total hardness of 1,62 mol/m³ for the supply zone Affaltrach, Eschenau, Sülzbach und Willsbach — that corresponds to 9.1 °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 08/07/2026.
