Drinking water in 78736
For this postcode Zweckverband Wasserversorgung Kleiner Heuberg 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
12 % Share of the parametric value. The proportion of the permitted maximum that the measured value uses — here 12 %, so just over an eighth.
< 10 % * Below the limit of quantification. The substance was not detectable. The mark shows where the detection limit lies relative to the parametric value — the actual share of the parametric value is below that.
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.

These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 30/10/2024. 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.

Frequent questions about postcode 78736
- How hard is the water in Postcode 78736?
- Zweckverband Wasserversorgung Kleiner Heuberg publishes a total hardness of 11.2 °dH for the supply zone ZV WV Kleiner Heuberg / HHB/WT Brittheim (HB Brittheim Entnahme) (hardness range mittel). 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: 01.04.2026, retrieved on 14/07/2026.
- How much nitrate is in the drinking water in Postcode 78736?
- Zweckverband Wasserversorgung Kleiner Heuberg publishes a nitrate value of 18 mg/l for the supply zone ZV WV Kleiner Heuberg / HHB/WT Brittheim (HB Brittheim Entnahme). The statutory parametric value is 50 mg/l; the measured value represents 36 % of the parametric value. Basis: 01.04.2026, retrieved on 14/07/2026.
- Are PFAS detectable in the drinking water in Postcode 78736?
- Zweckverband Wasserversorgung Kleiner Heuberg publishes for the supply zone ZV WV Kleiner Heuberg / HHB/WT Brittheim (HB Brittheim Entnahme) a sum value PFAS-20 below the limit of quantification (entry in the report: "<0,0000010 mg/l"). This is not to be read as "PFAS-free": below the limit of quantification, the measurement cannot make any statement. The statutory parametric value is 0.1 µg/l; the measured value lies below it and cannot be specified more precisely below the limit of quantification. For the sum of the 20 individual substances, this parametric value has applied since 12/01/2026. Basis: 01.04.2026, retrieved on 14/07/2026.
- Who supplies the drinking water in Postcode 78736?
- Zweckverband Wasserversorgung Kleiner Heuberg. The values shown here come from the supply zone ZV WV Kleiner Heuberg / HHB/WT Brittheim (HB Brittheim Entnahme) 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.
