Drinking water in 6014 (Switzerland)
For this postcode the responsible water supplier 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 9 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.

Values available, but not released
We hold evaluated analysis results for this supply zone. They come from the platform trinkwasser.ch of the Swiss Gas and Water Industry Association (SVGW). On 20/08/2026 the SVGW objected in writing to the use of this data for maunawai.info. We comply with this and do not show the values.
The current values of your water supplier are available directly from WV Littau-Berg or on trinkwasser.ch.
13 parameters are recorded: Aerobic mesophilic bacteria, Calcium, Chloride, Chlorothalonil metabolite R417888, Chlorothalonil metabolite R471811, Escherichia coli (E. coli), Intestinal enterococci, Magnesium, Nitrate, Oxidisability, Temperature, Total hardness, Turbidity.

QWW Sonnenberg, Quellwasser roh
ewl (Energie Wasser Luzern)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 06/05/2025. 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.
