Drinking water in 4712 (Switzerland)
For this postcode Werkkommission Laupersdorf 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 4 underneath.
The values come from the SVGW platform trinkwasser.ch. Water utilities report there voluntarily; the SVGW does not verify the data. For each parameter, the minimum, maximum, average and median of one year are published; hardness in French degrees (°fH). On 20 August 2026 the SVGW objected in writing to the use of this data for maunawai.info: we do not show values from this source, but only name the parameters measured there. Analyses we obtained directly from the water supplier are shown in full.
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.
