Markt Manching publishes the drinking-water analysis for its own waterworks in a notice dated 4 March 2026, and the page gives total hardness of 3.13 mmol/l, or 17.5 °dH (312.4 mg/L CaCO₃), in the hard range. The notice prints no sampling date, so the date shown is the publication date. An older page on the municipal site lists 17.8 °dH, which matches the 2024 notice, so the 2026 figure 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).
