Range across supply zones: 230–273 mg/L.
2 supply zones — hardness varies by neighbourhood; the figure above is the median.
Hardness by district / supply zone
| °dH | mg/L | ||
|---|---|---|---|
| Fernwasser WW Torgau-Ost (Elbaue-Ostharz; Härtebereich mittel) | 12.9 | 230 | very hard |
| WVA Probstheida (Hauptversorgung Stadtgebiet, Härtebereich hart) | 15.3 | 273 | very hard |
Leipziger Wasserwerke publishes a 2025 annual average analysis for its supply points. Most of the city is served from the Probstheida waterworks at 273.1 mg/L CaCO₃, while long-distance water from the Torgau-Ost waterworks (Elbaue-Ostharz) is softer at 230.3 mg/L. The city figure is 251.7 mg/L, with calcium at 74 mg/L and magnesium at 11 mg/L. Scale builds up quickly in kettles and washing machines at this level, so a descaling routine pays off.
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).
Estimates for planning, not a quote. Check your appliance manual for exact settings.
