Stadtwerke Dingolfing reports 18.6 °dH for the whole town, from the Hochbehälter Dingolfing analysis of 5 November 2025, and classes it as hard. The same report gives 18.9 °dH for 2024 and 18.8 °dH for 2023, so the value has been stable for three years. The utility's web page still shows the 2023 figure, which is why the PDF is used here. At this level, descaling kettles and shower heads is a regular chore.
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).
