Hamburg Wasser's Grundwasserwerk Glinde publishes a 2025 analysis with a mean total hardness of 181.0 mg/L CaCO₃ (minimum 9.3, maximum 10.9 °dH in the report). The figure comes from this single waterworks, and the source does not confirm that it covers every street in Glinde, so treat it as the works value. A different reading of about 10.47 °dH appeared in a search snippet, but the PDF value is the one used here.
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).
