Drinking water in 9563 (Austria)
For this postcode Gemeinde Gnesau (Gemeindewasserversorgung Gnesau) 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 5 underneath.
The values come from the Austrian drinking water database, to which water suppliers report voluntarily. In each case the highest value of the published range is given.
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 9563
- How hard is the water in Postcode 9563?
- Gemeinde Gnesau (Gemeindewasserversorgung Gnesau) publishes a total hardness of 0,76 mmol/l for the supply zone Volksschule Gnesau, Wasserhahn Wirtschaftsraum (Analysennr. 292982) — that corresponds to 4.3 °dH. Hardness indicates how much calcium and magnesium are dissolved in the water. It is not a quality assessment: there is no parametric value for hardness. Basis: 23.02.2026, retrieved on 11/08/2026.
- How much nitrate is in the drinking water in Postcode 9563?
- Gemeinde Gnesau (Gemeindewasserversorgung Gnesau) publishes a nitrate value of 2,52 mg/l for the supply zone Volksschule Gnesau, Wasserhahn Wirtschaftsraum (Analysennr. 292982). The statutory parametric value is 50 mg/l; the measured value represents 5 % of the parametric value. Basis: 23.02.2026, retrieved on 11/08/2026.
- Who supplies the drinking water in Postcode 9563?
- Gemeinde Gnesau (Gemeindewasserversorgung Gnesau). The values shown here come from the supply zone Volksschule Gnesau, Wasserhahn Wirtschaftsraum (Analysennr. 292982) 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.
