The only analysis we found for Kirchlengern is one tap sample at the town hall, taken in February 2023 and published by Energie- und Wasserversorgung Bünde (EWB). The lab calculated 405.2 mg/L CaCO₃ from its calcium and magnesium results, which is hard under the WRMG. The figure is more than three years old and covers a single point, so it is a rough guide rather than a current town-wide value. Ask EWB for its latest analysis before sizing a softener.
German law (WRMG) uses 3 bands: soft < 8.4 °dH, medium 8.4–14 °dH, hard > 14 °dH.

What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
