Drinking water in 66780
For this postcode Technische Werke der Gemeinde Rehlingen-Siersburg GmbH (TWRS) 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 2 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.

Technische Werke der Gemeinde Rehlingen-Siersburg GmbH (TWRS)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 30/09/2024. 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 66780
- How hard is the water in Postcode 66780?
- Technische Werke der Gemeinde Rehlingen-Siersburg GmbH (TWRS) publishes a total hardness of 8.5 °dH for the supply zone TWA Rehlingen / Z Förderleitung ON (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: 1. Ausfertigung vom 22.10.2024, retrieved on 08/07/2026.
- How much nitrate is in the drinking water in Postcode 66780?
- Technische Werke der Gemeinde Rehlingen-Siersburg GmbH (TWRS) publishes a nitrate value of 13,5 mg/l for the supply zone TWA Rehlingen / Z Förderleitung ON. The statutory parametric value is 50 mg/l; the measured value represents 27 % of the parametric value. Basis: 1. Ausfertigung vom 22.10.2024, retrieved on 08/07/2026.
- Who supplies the drinking water in Postcode 66780?
- Technische Werke der Gemeinde Rehlingen-Siersburg GmbH (TWRS). The values shown here come from the supply zone TWA Rehlingen / Z Förderleitung ON 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.
